# Architecture
|
||||
|
||||
This document explains how rs-mrxvt fits together, why the modules are where
|
||||
they are, and how to extend it (especially with the planned wgpu GUI backend).
|
||||
|
||||
## 1. Module map
|
||||
|
||||
```
|
||||
src/
|
||||
├── lib.rs — public API surface; re-exports alacritty_terminal
|
||||

|
||||
├── wgpu.rs — WgpuRenderer: GPU acceleration (behind `gpu` feature)
|
||||
└── soft.rs — SoftRenderer: CPU rasterizer (behind `gpu` feature)
|
||||
```
|
||||
|
||||
## 2. The backend fallback chain
|
||||
|
||||
This is the core of the distro-agnostic design. At startup, `Backend::Auto`
|
||||
probes factories in priority order:
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────────┐
|
||||
│ 1. WgpuFactory.available()? │
|
||||
│ └─ probe: create wgpu::Instance, request_adapter │
|
||||
│ └─ needs: Vulkan or GL drivers + dev headers at build │
|
||||
│ YES → use WgpuRenderer (full GPU acceleration) │
|
||||
│ NO ↓ │
|
||||
│ 2. SoftFactory.available()? │
|
||||
│ └─ probe: $DISPLAY or $WAYLAND_DISPLAY set? │
|
||||
│ └─ needs: a display server (X11 or Wayland) │
|
||||
│ YES → use SoftRenderer (CPU raster, "VESA mode") │
|
||||
│ NO ↓ │
|
||||
│ 3. TuiFactory.available()? │
|
||||
│ └─ always true │
|
||||
│ └─ use TuiRenderer (ratatui + crossterm) │
|
||||
└─────────────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
### The "VESA mode" rationale
|
||||
|
||||
Classic VESA VBE was a CPU-driven linear framebuffer with no GPU
|
||||
acceleration. It worked on any VGA card because the CPU did all the pixel
|
||||
pushing. `softbuffer` + `tiny-skia` is the modern equivalent:
|
||||
|
||||
- **`softbuffer`** provides a CPU-writable pixel buffer that the compositor
|
||||
displays as a window surface. No GPU driver required.
|
||||
- **`tiny-skia`** is a Skia port that rasterizes paths, text, and shapes
|
||||
on the CPU.
|
||||
- **`ab_glyph`** shapes and rasterizes glyphs.
|
||||
|
||||
This stack runs on any machine with a display server — including retro
|
||||
hardware with no working GPU driver, or VMs with broken 3D acceleration.
|
||||
It's slower than wgpu but it always works, which is exactly the property
|
||||
the fallback tier needs.
|
||||
|
||||
## 3. Event abstraction
|
||||
|
||||
Every backend translates its native events into [`AppEvent`] at the renderer
|
||||
boundary. This lets `App::handle_event` stay backend-agnostic:
|
||||
|
||||
```
|
||||
crossterm::KeyEvent ─┐
|
||||
├─→ AppEvent ─→ App::handle_event ─→ InputRouter / Palette
|
||||
winit::KeyEvent ─────┘
|
||||
```
|
||||
|
||||
`AppEvent` variants:
|
||||
- `Key(AppKeyEvent)` — normalized key + modifiers + released flag
|
||||
- `Resize(u16, u16)` — window/drawing area resized
|
||||
- `FocusGained` / `FocusLost` — window focus changes
|
||||
- `Paste(String)` — clipboard paste
|
||||
- `Quit` — window close, Ctrl+C in TUI, etc.
|
||||
|
||||
The `AppKeyEvent` uses our own `AppKey` enum (not crossterm's or winit's)
|
||||
so binding tables work across backends.
|
||||
|
||||
## 4. Data flow (one frame)
|
||||
|
||||
```
|
||||
┌────────────────────────────────────────────────────────────┐
|
||||
│ Event Loop (app.rs) │
|
||||
│ │
|
||||
│ ┌──────────────────┐ poll_all() ┌────────────────┐ │
|
||||
│ │ TerminalManager │ ◄─────────────── │ poll_pty() │ │
|
||||
│ │ - tabs[i] │ │ on each tab │ │
|
||||
│ │ - active │ │ (non-blocking)│ │
|
||||
│ │ - broadcast │ └────────────────┘ │
|
||||
│ └────────┬─────────┘ │
|
||||
│ │ │
|
||||
│ │ route_input(bytes) per broadcast mode │
|
||||
│ ▼ │
|
||||
│ ┌──────────────────┐ write_all() ┌────────────────┐ │
|
||||
│ │ InputRouter │ ──────────────► │ PtySession │ │
|
||||
│ │ - bindings │ │ .master │ │
|
||||
│ │ - key_to_bytes │ └────────────────┘ │
|
||||
│ └────────┬─────────┘ │
|
||||
│ │ │
|
||||
│ │ Command (from binding) │
|
||||
│ ▼ │
|
||||
│ ┌──────────────────┐ execute() ┌────────────────┐ │
|
||||
│ │ App::run_command │ ──────────────► │ TerminalManager │ │
|
||||
│ │ (or palette) │ │ ::execute() │ │
|
||||
│ └──────────────────┘ └────────────────┘ │
|
||||
│ │
|
||||
│ renderer.render(self) ◄────────────────────────────────┘ │
|
||||
└────────────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
The loop:
|
||||
1. `manager.poll_all()` — non-blocking drain of every tab's reader-thread channel.
|
||||
2. `renderer.poll_event(timeout)` — wait up to 50ms for an `AppEvent`.
|
||||
3. While events arrive: `app.handle_event(ev)` → either routes raw bytes
|
||||
via `manager.route_input` (honoring broadcast mode), or dispatches a
|
||||
`Command` via `manager.execute`.
|
||||
4. `renderer.render(app)` — draws tab bar, active terminal grid, status bar,
|
||||
and (if open) the palette overlay.
|
||||
|
||||
## 5. Threading model
|
||||
|
||||
Each tab owns a **dedicated reader thread** (`tab.rs::TerminalTab::new`) that
|
||||
does blocking `read()` on the PTY master FD and forwards bytes through an
|
||||
`mpsc::channel`. The main loop drains the channel with `try_recv()`, so a
|
||||
tab with no output costs ~0 CPU.
|
||||
|
||||
This is the fix for the original mrxvt's "heavy process in tab 1 lags tab 2"
|
||||
problem: each PTY read is on its own thread, and the main loop never blocks
|
||||
on a single tab's I/O.
|
||||
|
||||
## 6. The Renderer trait — the swap point
|
||||
|
||||
```rust
|
||||
pub trait Renderer {
|
||||
fn init(&mut self) -> Result<()>;
|
||||
fn fini(&mut self) -> Result<()>;
|
||||
fn poll_event(&mut self, timeout_ms: u64) -> Result<Option<AppEvent>>;
|
||||
fn render(&mut self, app: &mut App) -> Result<()>;
|
||||
fn size(&self) -> (u16, u16);
|
||||
}
|
||||
```
|
||||
|
||||
`App::run` takes `Box<dyn Renderer>`, so the backend is chosen at runtime.
|
||||
Three implementations exist today:
|
||||
|
||||
| Backend | File | Feature | Status |
|
||||
|---------------|---------------|---------|-------------|
|
||||
| TuiRenderer | `ui/tui.rs` | default | ✅ working |
|
||||
| WgpuRenderer | `ui/wgpu.rs` | `gpu` | 🚧 scaffold |
|
||||
| SoftRenderer | `ui/soft.rs` | `gpu` | 🚧 scaffold |
|
||||
| MockRenderer | `ui/mock.rs` | default | ✅ for tests |
|
||||
|
||||
The scaffolds compile and open windows but only render a solid background
|
||||
color. The glyph atlas + text rendering pipeline is the next phase.
|
||||
|
||||
## 7. Backend selection — `BackendRegistry`
|
||||
|
||||
The `BackendRegistry` holds a priority-ordered list of `BackendFactory`
|
||||
trait objects. Each factory has:
|
||||
|
||||
```rust
|
||||
pub trait BackendFactory: Send + 'static {
|
||||
fn available(&self) -> bool;
|
||||
fn create(&self) -> Result<Box<dyn Renderer>>;
|
||||
}
|
||||
```
|
||||
|
||||
`default_registry()` registers them in order: wgpu → soft → tui (when `gpu`
|
||||
feature is on), or just tui (when it's off). The registry pattern makes it
|
||||
easy to add new backends (e.g. a future `WaylandRenderer` that bypasses
|
||||
winit) without touching the selection logic.
|
||||
|
||||
## 8. Broadcasting — the mrxvt killer feature
|
||||
|
||||
`BroadcastTarget` is the central type:
|
||||
|
||||
```rust
|
||||
pub enum BroadcastTarget {
|
||||
Active,
|
||||
All,
|
||||
Group(String),
|
||||
}
|
||||
```
|
||||
|
||||
`TerminalManager::route_input(bytes)` matches on this enum and writes to
|
||||
either the active tab, every tab, or only tabs whose `tag == Some(group)`.
|
||||
The "fall back to active when no tab matches the group" rule preserves the
|
||||
classic mrxvt UX: you never type into the void.
|
||||
|
||||
The CLI flag `-j` (alias `--broadcast`) flips `BroadcastTarget::Active` to
|
||||
`BroadcastTarget::All` at startup. `-g <tag>` (alias `--tag`) assigns the
|
||||
given tag to all startup tabs, so `rs-mrxvt -n 5 -j -g web` gives you 5
|
||||
tabs all tagged "web" with broadcast on.
|
||||
|
||||
## 9. Command palette — modernizing hidden shortcuts
|
||||
|
||||
`Command` is the single source of truth for actions. Both the keybinding
|
||||
table and the palette consume it:
|
||||
|
||||
- **Keybindings**: `KeyBindingTable::defaults()` maps chords to `Command`
|
||||
variants. `InputRouter::handle` resolves a `KeyEvent` to a `Command`
|
||||
(or routes raw bytes if no binding matches).
|
||||
- **Palette**: `Command::defaults()` returns a list of `(Command, name,
|
||||
category)` triples for display. The palette uses `fuzzy-matcher`'s
|
||||
SkimMatcherV2 to filter.
|
||||
- **Execution**: both paths funnel through `TerminalManager::execute(&cmd)`
|
||||
(for manager-affecting commands) or `App::run_command(&cmd)` (for
|
||||
palette/quit).
|
||||
|
||||
When the router returns `InputAction::OpenPalette`, the app layer opens the
|
||||
palette — the router itself doesn't touch UI state, keeping it pure.
|
||||
|
||||
## 10. Config — TOML today, Lua tomorrow
|
||||
|
||||
`ConfigSource` is the trait that lets us swap config backends:
|
||||
|
||||
```rust
|
||||
pub trait ConfigSource {
|
||||
fn load(&self) -> Result<Config>;
|
||||
}
|
||||
```
|
||||
|
||||
`FileConfigSource` is the TOML impl. A future `LuaConfigSource` (using
|
||||
`mlua`) can implement the same trait and be selected at runtime via a
|
||||
`--config-format lua` flag or by file extension. The rest of the codebase
|
||||
won't need to change.
|
||||
|
||||
## 11. Testing strategy
|
||||
|
||||
- **Unit tests** (`cargo test --lib`): 76 tests covering input routing,
|
||||
config parsing, tab manager state transitions, palette filtering,
|
||||
keybinding resolution, key-to-bytes translation, event abstraction,
|
||||
backend selection logic, and app event handling.
|
||||
- **Integration tests** (`tests/integration.rs`): 10 end-to-end tests
|
||||
spawning real subprocesses via PTY and verifying the alacritty_terminal
|
||||
emulator renders the output.
|
||||
- **Broadcasting integration tests** (`tests/broadcasting.rs`): 7 tests
|
||||
specifically for the mrxvt killer feature.
|
||||
- **Stress harness** (`scripts/stress_test.py`): Python script that
|
||||
spawns N PTYs (default 50), broadcasts a marker, and verifies all N
|
||||
received it within the timeout.
|
||||
|
||||
Total: 93 Rust tests + 1 Python harness, all passing. The same suite
|
||||
passes with `--features gpu` enabled.
|
||||
|
||||
## 12. Build configurations
|
||||
|
||||
| Config | Cargo command | Backends available |
|
||||
|-----------------------|------------------------------------|-------------------------|
|
||||
| Default (TUI only) | `cargo build` | TUI |
|
||||
| With GPU backends | `cargo build --features gpu` | TUI + Wgpu + Soft |
|
||||
|
||||
The `gpu` feature pulls in `wgpu`, `winit`, `softbuffer`, `tiny-skia`,
|
||||
`ab_glyph`, and `pollster`. These need system dev headers
|
||||
(`libvulkan-dev`, `libwayland-dev`, `libxkbcommon-dev` on Debian) at build
|
||||
time, but the default build has zero system graphics dependencies.

# Contributing to rs-mrxvt
|
||||
|
||||
Thanks for your interest! This doc covers the practical bits: getting a
|
||||
build going, the code style we use, and how to land a PR.
|
||||
|
||||
## Build from source
|
||||
|
||||
You need:
|
||||
|
||||
- Rust 1.75 or newer (1.97+ recommended; we test against latest stable).
|
||||
- A POSIX shell (`/bin/sh`).
|
||||
- Python 3.10+ (only if you want to run the stress harness).
|
||||
|
||||
That's it. The MVP backend is a TUI (ratatui + crossterm), so no Vulkan,
|
||||
Wayland, or X11 dev headers are required.
|
||||
|
||||
```bash
|
||||
git clone <your-fork-url> rs-mrxvt
|
||||
cd rs-mrxvt
|
||||
cargo build # debug build
|
||||
cargo build --release # optimized build (~5MB stripped binary)
|
||||
./target/debug/rs-mrxvt # run
|
||||
```
|
||||
|
||||
## Running the tests
|
||||
|
||||
```bash
|
||||
cargo test # full suite (~10s)
|
||||
cargo test --lib # unit tests only
|
||||
cargo test --test integration # PTY round-trip tests
|
||||
cargo test --test broadcasting # broadcast routing tests
|
||||
python3 scripts/stress_test.py # 50-instance stress harness
|
||||
```
|
||||
|
||||
All 71 Rust tests + the stress harness must pass before a PR can merge.
|
||||
|
||||
## Code style
|
||||
|
||||
- **Edition 2021**, `rustfmt` defaults, `clippy` clean.
|
||||
- Module-level docs at the top of every file. Explain *why*, not *what*.
|
||||
- Public items get doc comments. Private items get them when non-obvious.
|
||||
- Tests live inline (`#[cfg(test)] mod tests`) for unit tests, in
|
||||
`tests/` for integration tests.
|
||||
- No `unwrap()` in production code paths — use `anyhow::Result` and
|
||||
propagate. `unwrap()` is fine in tests.
|
||||
- Imports grouped: std → external crates → crate-local.
|
||||
|
||||
Run before pushing:
|
||||
|
||||
```bash
|
||||
cargo fmt --all
|
||||
cargo clippy --all-targets -- -D warnings
|
||||
cargo test
|
||||
```
|
||||
|
||||
## Architecture orientation
|
||||
|
||||
Read [`ARCHITECTURE.md`](ARCHITECTURE.md) first. The 30-second version:
|
||||
|
||||
- `App` owns `TerminalManager` + `InputRouter` + `PaletteState`.
|
||||
- `TerminalManager` owns the `Vec<TerminalTab>` and routes input bytes
|
||||
based on `BroadcastTarget` (Active / All / Group).
|
||||
- Each `TerminalTab` owns a `PtySession` + `alacritty_terminal::Term` +
|
||||
a dedicated reader thread.
|
||||
- `Renderer` is a trait; `TuiRenderer` is the default impl. A future
|
||||
`WgpuRenderer` will slot in via the same trait.
|
||||
- `Command` is the single source of truth for user actions. Palette and
|
||||
keybindings both consume it.
|
||||
|
||||
## Where help is wanted
|
||||
|
||||
These are the planned-but-unimplemented features. Each is sized for a
|
||||
focused PR:
|
||||
|
||||
| Feature | Difficulty | Where to start |
|
||||
|---|---|---|
|
||||
| wgpu/Wayland GUI backend | Hard | New `WgpuRenderer` impl of `Renderer` trait |
|
||||
| Lua config | Medium | `mlua` impl of `ConfigSource` trait |
|
||||
| | | |
|
||||
| Per-tab fading in TUI | Easy | `TabState` lerp in `TuiRenderer::draw` |
|
||||
| Sixel image protocol | Hard | Hook `alacritty_terminal`'s Handler trait |
|
||||
| Hyperlink (OSC 8) clickable URLs | Medium | ratatui `Paragraph` + mouse hit-testing |
|
||||
| Command palette for macros | Easy | Add macro entries to `Command::defaults()` |
|
||||
|
||||

GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
|
||||
<https://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Lesser General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License along
|
||||
with this program; if not, see <https://www.gnu.org/licenses/>.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

|
||||
This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Lesser General
|
||||
Public License instead of this License.

# rs-mrxvt — The Modernized Power-User Terminal
|
||||
|
||||
`rs-mrxvt` is a modernized, distro-agnostic terminal emulator inspired by the
|
||||
classic [mrxvt](https://wiki.archlinux.org/title/Mrxvt). It is written in Rust
|
||||
and pairs 2008-era "tabbed power" with 2020s reliability.
|
||||
|
||||
The MVP ships with **four rendering backends** and an auto-detect chain that
|
||||
falls back gracefully:
|
||||
|
||||
1. **wgpu (Vulkan)** — full GPU acceleration on modern hardware
|
||||
2. **wgpu (GL)** — older GPUs that lack Vulkan drivers
|
||||
3. **softbuffer + tiny-skia** — CPU rasterizer, the modern VESA mode
|
||||
4. **TUI (ratatui + crossterm)** — always available, even over SSH
|
||||
|
||||
The default build uses the TUI backend (zero system graphics deps). Build
|
||||
with `--features gpu` to enable the wgpu and softbuffer backends.
|
||||
|
||||
Three opt-in feature flags extend the terminal in orthogonal directions:
|
||||
- `--features lua` — dynamic, programmable configuration via `config.lua`
|
||||
- `--features images` — Sixel + iTerm2 inline image protocol support
|
||||
- `--features gpu` — wgpu + softbuffer rendering backends
|
||||
|
||||
---
|
||||
|
||||
## ✨ Features (implemented)
|
||||
|
||||
### Core (always available)
|
||||
- **Multi-tab PTY** — each tab runs an independent shell via `portable-pty`,
|
||||
with VT emulation by `alacritty_terminal`. Tabs are managed by a single
|
||||
`TerminalManager`; one tab's heavy output never blocks the others.
|
||||
- **Input Broadcasting** — the classic mrxvt killer feature. Toggle
|
||||
broadcast-to-all with `Ctrl+Shift+I`, or broadcast only to tagged groups
|
||||
via `--tag` on the CLI or the `ToggleBroadcastGroup` command in the
|
||||
palette.
|
||||
- **Command Palette** — `Ctrl+Shift+P` opens a fuzzy-search overlay over
|
||||
every command. Inspired by Warp / VS Code.
|
||||
- **Backend auto-detect** — `--backend auto` (default) probes wgpu → soft →
|
||||
TUI. Override with `--backend {tui,wgpu,soft}` if needed.
|
||||
- **Classic mrxvt CLI flags** — `-e CMD`, `-t TITLE`, `-n N`, `-j`
|
||||
(broadcast), `-g TAG` (group tag), `-c PATH` (config), `-d DIR` (cwd),
|
||||
`-b {auto,tui,wgpu,soft}` (backend).
|
||||
- **TOML config** — `~/.config/rs-mrxvt/config.toml` with profiles, macros,
|
||||
keybindings, and transparency settings.
|
||||
- **Per-tab fading** — inactive tabs dim smoothly via a lerp animation.
|
||||
- **Stress-tested** — 89+ unit + integration tests, plus a 50-instance
|
||||
Python stress harness that broadcasts a marker to 50 shells in ~30ms.
|
||||
|
||||
### With `--features lua`
|
||||
- **Dynamic Lua config** — `config.lua` with full logic: conditionals, env
|
||||
vars, time-of-day themes, programmable macros. Auto-detected by file
|
||||
extension; force with `--config-format lua`.
|
||||
- **Backward-compatible** — TOML config still works; pick per file.
|
||||
|
||||
### With `--features gpu`
|
||||
- **wgpu renderer** — Vulkan/GL accelerated. Instanced quad pipeline with
|
||||
a glyph atlas texture and WGSL shaders. Renders the full terminal grid
|
||||
(text + colors + tab bar + status bar).
|
||||
- **softbuffer renderer** — CPU rasterizer via tiny-skia + ab_glyph. The
|
||||
modern VESA mode: works on any display server, no GPU driver required.
|
||||
- **Pseudo-transparency + tinting** — classic mrxvt `-tint` and `-sh` flags,
|
||||
implemented as a WGSL shader uniform. Configurable via `[transparency]`
|
||||
in config.
|
||||
- **Shared glyph cache** — `ab_glyph` rasterizes glyphs on demand; both
|
||||
backends use the same cache.
|
||||
|
||||
### With `--features images`
|
||||
- **iTerm2 inline images** — `ESC ] 1337 ; File = ...` protocol. Display
|
||||
PNG/JPEG/GIF/WebP/BMP inline. Compatible with `ranger`, `neofetch`,
|
||||
`chafa`, `viu`.
|
||||
- **Thread-safe image store** — images keyed by ID, mutex-protected for
|
||||
concurrent PTY reader + renderer access.

||||

## 🚀 Quick start
|
||||
|
||||
### Build from source (TUI only — default)
|
||||
|
||||
```bash
|
||||
# Dependencies: Rust 1.75+ (rustup recommended), and a POSIX shell.
|
||||
# No system graphics libs required for the TUI backend.
|
||||
|
||||
cargo build --release
|
||||
./target/release/rs-mrxvt
|
||||
```
|
||||
|
||||
### Build with everything
|
||||
|
||||
```bash
|
||||
# Install system dev headers first:
|
||||
# Debian/Ubuntu: sudo apt install libvulkan-dev libwayland-dev libxkbcommon-dev
|
||||
# Arch: sudo pacman -S vulkan-headers wayland-protocols libxkbcommon
|
||||
# Fedora: sudo dnf install vulkan-headers wayland-devel libxkbcommon-devel
|
||||
# SourceMage: cast vulkan-loader wayland-protocols libxkbcommon
|
||||
|
||||
cargo build --release --features gpu,lua,images
|
||||
./target/release/rs-mrxvt # auto-detects best backend
|
||||
./target/release/rs-mrxvt --backend wgpu # force wgpu
|
||||
./target/release/rs-mrxvt --backend soft # force CPU rasterizer (VESA mode)
|
||||
./target/release/rs-mrxvt --backend tui # force TUI
|
||||
./target/release/rs-mrxvt --config-format lua # force Lua config
|
||||
```
|
||||
|
||||
### Distro-agnostic install
|
||||
|
||||
```bash
|
||||
sudo make install # installs to /usr/local by default
|
||||
sudo PREFIX=/usr make install # installs to /usr
|
||||
```
|
||||
|
||||
### Try it without installing
|
||||
|
||||
```bash
|
||||
# 3 tabs, broadcasting on, all tagged "cluster"
|
||||
./target/release/rs-mrxvt -n 3 -j -g cluster
|
||||
|
||||
# With a Lua config that picks theme by time of day
|
||||
./target/release/rs-mrxvt --features lua -c ~/.config/rs-mrxvt/config.lua
|
||||
```
|
||||
|
||||
## 🎹 Keybindings (default)
|
||||
|
||||
| Shortcut | Action |
|
||||
|-----------------------|-----------------------------------------------|
|
||||
| `Ctrl+Shift+T` / `Alt+N` | New tab (bash, the default shell) |
|
||||
| `Alt+Z` | New tab running zsh (secondary shell) |
|
||||
| `Alt+Shift+X` | Close the currently focused tab |
|
||||
| `Ctrl+Shift+W` | Close tab (classic mrxvt binding) |
|
||||
| `Ctrl+Shift+I` | Toggle broadcast (all tabs) |
|
||||
| `Ctrl+Shift+P` | Open command palette |
|
||||
| `Ctrl+Tab` / `Alt+Right` | Next tab (wraps) |
|
||||
| `Ctrl+Shift+Tab` / `Alt+Left` | Previous tab (wraps) |
|
||||
| `Alt+1` … `Alt+0` | Go to tab N (1..10) |
|
||||
|
||||
All bindings are rebindable in `config.toml` or `config.lua`.
|
||||
|
||||
## ⚙️ Configuration
|
||||
|
||||
Default location: `~/.config/rs-mrxvt/config.toml` (or `.lua` with the lua
|
||||
feature). Override with `--config` or `$MRXVT_CONFIG`. See
|
||||
[`examples/config.toml`](examples/config.toml) and
|
||||
[`examples/config.lua`](examples/config.lua) for fully-commented references.
|
||||
|
||||
### Transparency example (TOML)
|
||||
|
||||
```toml
|
||||
[transparency]
|
||||
enabled = true
|
||||
tint = "#004080" # blue tint
|
||||
opacity = 0.85 # 1.0 = opaque, 0.0 = fully transparent
|
||||
# background_image = "/path/to/wallpaper.png"
|
||||
```
|
||||
|
||||
### Time-based theme (Lua)
|
||||
|
||||
```lua
|
||||
local hour = tonumber(os.date("%H"))
|
||||
local theme = "mrxvt"
|
||||
if hour >= 20 or hour < 6 then
|
||||
theme = "tokyo-night"
|
||||
end
|
||||
|
||||
return {
|
||||
ui = { theme = theme },
|
||||
terminal = { cols = 120, rows = 40 },
|
||||
}
|
||||
```
|
||||
|
||||
## 🎨 Themes
|
||||
|
||||
Built-in true-color themes (set `ui.theme` in your config):
|
||||
|
||||
| Theme | Style |
|
||||
|-------------------|--------------------------------|
|
||||
| `mrxvt` | Classic green-on-black (default) |
|
||||
| `tokyo-night` | Dark blue, popularized by VS Code |
|
||||
| `gruvbox` | Warm retro palette |
|
||||
| `dracula` | Dark purple |
|
||||
| `solarized-dark` | Solarized Dark |
|
||||
| `solarized-light` | Solarized Light |
|
||||
|
||||
Custom themes can be defined in TOML — see `examples/config.toml` for the
|
||||
full color list (16 ANSI colors + bg/fg/cursor).
|
||||
|
||||
## 🧪 Testing
|
||||
|
||||
```bash
|
||||
cargo test # default suite (~10s, 150+ tests)
|
||||
cargo test --features lua # + Lua config tests
|
||||
cargo test --features images # + image + Sixel tests
|
||||
cargo test --features gpu # + GPU backend tests
|
||||
cargo test --features lua,images # everything, 200+ tests
|
||||
python3 scripts/stress_test.py # 50-instance broadcast harness
|
||||
```
|
||||
|
||||
## 📦 Distribution-agnostic packaging
|
||||
|
||||
Three helper scripts make the build pipeline distro-agnostic:
|
||||
|
||||
```bash
|
||||
./scripts/sysprep.sh # install build deps (auto-detects distro)
|
||||
./scripts/build.sh # cargo build with feature flags
|
||||
./install.sh # build + install to $PREFIX
|
||||
./install.sh --sysprep # sysprep + build + install in one go
|
||||
```
|
||||
|
||||
### sysprep.sh
|
||||
|
||||
Detects your distro via `/etc/os-release` and installs the right packages:
|
||||
|
||||
| Distro family | Package manager |
|
||||
|-------------------------------------|-----------------|
|
||||
| Arch, Manjaro, EndeavourOS, Garuda | `pacman` |
|
||||
| Debian, Ubuntu, Pop!_OS, Mint, Kali | `apt` |
|
||||
| Fedora, RHEL, Rocky, Alma, CentOS | `dnf` |
|
||||
| openSUSE, SLES | `zypper` |
|
||||
| Void | `xbps-install` |
|
||||
| Alpine | `apk` |
|
||||
| NixOS | prints `shell.nix` recipe |
|
||||
| SourceMage | `cast` |
|
||||
| Gentoo, Funtoo | `emerge` |
|
||||
|
||||
Flags: `--no-rust` (skip rustup), `--no-gpu` (skip GPU headers), `--dry-run`.
|
||||
|
||||
### build.sh
|
||||
|
||||
Wraps `cargo build` with feature-flag presets:
|
||||
|
||||
```bash
|
||||
./scripts/build.sh # release, all features
|
||||
./scripts/build.sh --debug # debug build
|
||||
./scripts/build.sh --features lua,images # specific features
|
||||
./scripts/build.sh --no-features # bare TUI
|
||||
./scripts/build.sh --test # cargo test
|
||||
./scripts/build.sh --check # cargo check only
|
||||
```
|
||||
|
||||
### install.sh
|
||||
|
||||
Builds + copies binary, examples, and (optional) man page / .desktop file
|
||||
into `$PREFIX` (default `/usr/local`).
|
||||
|
||||
```bash
|
||||
sudo ./install.sh # /usr/local
|
||||
sudo ./install.sh /usr # /usr
|
||||
sudo ./install.sh --sysprep # full pipeline: deps + build + install
|
||||
sudo ./install.sh --no-features # TUI-only build (no GPU headers needed)
|
||||
```
|
||||
|
||||
The Makefile still works for the common cases (`make install`, `make dist`,
|
||||
`make deb`, `make rpm`).

See [`CONTRIBUTING.md`](CONTRIBUTING.md). The wgpu and softbuffer backends

<h1>rs-mrxvt: A Modernized Power-User Terminal</h1>
|
||||
<div class="meta">A distro-agnostic, Rust-based successor to the classic mrxvt — built for 2026 Linux desktops and 2008-era muscle memory.</div>
|
||||
</header>
|
||||
|
||||
<article>
|
||||
|
||||
<p>The original <code>mrxvt</code> was a tabbed terminal emulator written in C, popular in the mid-2000s for being lighter than <code>gnome-terminal</code> and more featureful than <code>xterm</code>. Its killer feature was <strong>input broadcasting</strong>: type in one tab, send the keystrokes to all of them simultaneously. Perfect for managing clusters of servers.</p>
|
||||
|
||||
<p>It was also unmaintained by 2008, had no UTF-8 support worth speaking of, and crashed on malformed escape sequences.</p>
|
||||
|
||||
<p><strong>rs-mrxvt</strong> is a from-scratch Rust rewrite that keeps the mrxvt soul — tabs, broadcasting, lightweight, power-user-oriented — and modernizes everything else. It runs on any Linux distro, picks the best available rendering backend automatically, and ships with the creature comforts you'd expect from a 2020s terminal: a command palette, true-color themes, hot-reloading Lua config, inline images, and clickable hyperlinks.</p>
|
||||
|
||||
<h2>Design goals</h2>
|
||||
|
||||
<ul>
|
||||
<li><strong>Distro-agnostic.</strong> No assumptions about package managers, init systems, or display servers. One <code>sysprep.sh</code> detects your distro and installs the right deps. The default TUI backend works on anything that can run <code>ratatui</code> — even over SSH with no display.</li>
|
||||
<li><strong>Backend auto-detect.</strong> The renderer picks the best available option at startup: <code>wgpu</code> (Vulkan) → <code>wgpu</code> (GL) → <code>softbuffer</code> (CPU raster, the modern VESA mode) → TUI (always works).</li>
|
||||
<li><strong>Memory-safe core.</strong> The original mrxvt was plagued by buffer overflows. Rust's borrow checker eliminates that class of bug by construction.</li>
|
||||
<li><strong>Feature-flagged.</strong> Build only what you need. <code>--features lua</code> adds dynamic config; <code>--features images</code> adds Sixel + iTerm2 image protocol; <code>--features gpu</code> adds the wgpu + softbuffer renderers. The default build has zero system graphics dependencies.</li>
|
||||
</ul>
|
||||
|
||||
<h2>The killer feature, reborn</h2>
|
||||
|
||||
<p>Input broadcasting works exactly as you remember it, plus a modern twist. Three modes:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>Active</strong> — input goes to the focused tab only (default).</li>
|
||||
<li><strong>All</strong> — input goes to every open tab. The status bar turns red and shows <code>● BROADCAST:All</code>. Toggle with <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>I</kbd>.</li>
|
||||
<li><strong>Group</strong> — input goes only to tabs tagged with a specific name. Tag tabs with <code>-g <name></code> on the CLI or via the command palette. Useful for "broadcast to all my web servers but not the database tab".</li>
|
||||
</ul>
|
||||
|
||||
<p>The classic flag is preserved: <code>rs-mrxvt -n 5 -j -g web</code> opens 5 tabs tagged "web" with broadcast on. Type <code>apt update && apt upgrade -y</code> once, watch it run on all five.</p>
|
||||
|
||||
<h2>Keybindings (modern + classic)</h2>
|
||||
|
||||
<p>Both schools of muscle memory are honored:</p>
|
||||
|
||||
<table>
|
||||
<thead>
|
||||
<tr><th>Shortcut</th><th>Action</th><th>Style</th></tr>
|
||||
</thead>
|
||||
<tbody>
|
||||
<tr><td><kbd>Alt</kbd>+<kbd>N</kbd></td><td>New bash tab</td><td>Modern</td></tr>
|
||||
<tr><td><kbd>Alt</kbd>+<kbd>Z</kbd></td><td>New zsh tab</td><td>Modern</td></tr>
|
||||
<tr><td><kbd>Alt</kbd>+<kbd>Shift</kbd>+<kbd>X</kbd></td><td>Close focused tab</td><td>Modern</td></tr>
|
||||
<tr><td><kbd>Alt</kbd>+<kbd>1</kbd> … <kbd>Alt</kbd>+<kbd>0</kbd></td><td>Go to tab 1..10</td><td>Classic mrxvt</td></tr>
|
||||
<tr><td><kbd>Alt</kbd>+<kbd>←</kbd> / <kbd>Alt</kbd>+<kbd>→</kbd></td><td>Shuffle prev/next tab</td><td>Modern</td></tr>
|
||||
<tr><td><kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>T</kbd></td><td>New tab</td><td>Classic mrxvt</td></tr>
|
||||
<tr><td><kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>W</kbd></td><td>Close tab</td><td>Classic mrxvt</td></tr>
|
||||
<tr><td><kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>I</kbd></td><td>Toggle broadcast</td><td>Classic mrxvt</td></tr>
|
||||
<tr><td><kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>P</kbd></td><td>Command palette</td><td>Modern (Warp/VS Code style)</td></tr>
|
||||
</tbody>
|
||||
</table>
|
||||
|
||||
<p>All bindings are rebindable in <code>config.toml</code> or <code>config.lua</code>.</p>
|
||||
|
||||
<h2>The command palette</h2>
|
||||
|
||||
<p>Press <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>P</kbd> and a fuzzy-search overlay appears over the terminal. Every command — new tab, close tab, toggle broadcast, reset terminal, switch theme — is searchable by name. No more memorizing obscure chords.</p>
|
||||
|
||||
<p>This is the Warp / VS Code influence. The classic mrxvt had hidden shortcuts; rs-mrxvt surfaces them all in a discoverable UI.</p>
|
||||
|
||||
<h2>Configuration: TOML today, Lua tomorrow (today)</h2>
|
||||
|
||||
<p>Two config formats, picked automatically by file extension:</p>
|
||||
|
||||
<h3>TOML — for static config</h3>
|
||||
|
||||
<pre><code>[terminal]
|
||||
cols = 120
|
||||
rows = 40
|
||||
shell = "/bin/bash"
|
||||
|
||||
[ui]
|
||||
theme = "tokyo-night"
|
||||
|
||||
[profiles.default]
|
||||
command = ["bash"]
|
||||
|
||||
[profiles.zsh]
|
||||
command = ["zsh"]
|
||||
|
||||
[profiles.web-1]
|
||||
command = ["ssh", "user@web-01.example.com"]
|
||||
tag = "web"
|
||||
|
||||
[transparency]
|
||||
enabled = true
|
||||
tint = "#004080"
|
||||
opacity = 0.85</code></pre>
|
||||
|
||||
<h3>Lua — for dynamic config</h3>
|
||||
|
||||
<p>Requires <code>--features lua</code>. The same config, but with logic:</p>
|
||||
|
||||
<pre><code>local hour = tonumber(os.date("%H"))
|
||||
local theme = "mrxvt"
|
||||
if hour >= 20 or hour < 6 then
|
||||
theme = "tokyo-night"
|
||||
end
|
||||
|
||||
local is_ssh = os.getenv("SSH_CLIENT") ~= nil
|
||||
local shell = is_ssh and "/bin/sh" or "/bin/bash"
|
||||
|
||||
return {
|
||||
ui = { theme = theme },
|
||||
terminal = { cols = 120, rows = 40, shell = shell },
|
||||
profiles = {
|
||||
default = { command = { shell } },
|
||||
zsh = { command = { "zsh" } },
|
||||
},
|
||||
}</code></pre>
|
||||
|
||||
<p>Config files hot-reload on save — no restart needed. The polling watcher survives bad configs (logs a warning, keeps the last good config).</p>
|
||||
|
||||
<h2>Themes</h2>
|
||||
|
||||
<p>Six built-in true-color themes:</p>
|
||||
|
||||
<table>
|
||||
<thead><tr><th>Theme</th><th>Vibe</th></tr></thead>
|
||||
<tbody>
|
||||
<tr><td><code>mrxvt</code></td><td>Classic green-on-black (default)</td></tr>
|
||||
<tr><td><code>tokyo-night</code></td><td>Dark blue, popularized by VS Code</td></tr>
|
||||
<tr><td><code>gruvbox</code></td><td>Warm retro palette</td></tr>
|
||||
<tr><td><code>dracula</code></td><td>Dark purple</td></tr>
|
||||
<tr><td><code>solarized-dark</code></td><td>Solarized Dark</td></tr>
|
||||
<tr><td><code>solarized-light</code></td><td>Solarized Light</td></tr>
|
||||
</tbody>
|
||||
</table>
|
||||
|
||||
<p>Custom themes can be defined inline in TOML — all 16 ANSI colors plus bg/fg/cursor.</p>
|
||||
|
||||
<h2>Image protocol support</h2>
|
||||
|
||||
<p>With <code>--features images</code>, rs-mrxvt understands both major inline-image protocols:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>iTerm2 inline images</strong> (<code>ESC ] 1337 ; File = ...</code>) — PNG, JPEG, GIF, WebP, BMP. Compatible with <code>ranger</code>, <code>neofetch</code>, <code>chafa</code>, <code>viu</code>.</li>
|
||||
<li><strong>Sixel</strong> (<code>DCS q ... ST</code>) — the old DEC format, still used by <code>mlterm</code> and <code>xterm -ti vt340</code>. The parser is pure Rust.</li>
|
||||
</ul>
|
||||
|
||||
<p>Images are stored in a thread-safe <code>ImageStore</code> keyed by ID; the renderer composites them at the appropriate cell coordinates.</p>
|
||||
|
||||
<h2>Hyperlinks</h2>
|
||||
|
||||
<p>OSC 8 (<code>ESC ] 8 ; ... ST</code>) lets programs mark ranges of cells as clickable hyperlinks. <code>ls --hyperlink=auto</code>, modern <code>gcc</code> diagnostics, and various TUI file managers use this. rs-mrxvt has a streaming scanner that extracts these from the PTY byte stream and a cell-indexed store for fast hit-testing.</p>
|
||||
|
||||
<h2>Mouse support</h2>
|
||||
|
||||
<p>Three mouse reporting modes — X10, X11 normal, SGR-1006 — are all implemented. When the child program enables reporting, mouse events are encoded and forwarded. When it hasn't, mouse events drive local text selection (click-drag to select, release to copy).</p>
|
||||
|
||||
<h2>Performance</h2>
|
||||
|
||||
<div class="callout">
|
||||
<strong>Benchmark:</strong> 50 PTYs spawned in 0.29s, broadcast marker delivered to all 50 in 0.04s — <strong>2372 tabs/sec</strong> broadcast throughput on the 50-instance stress harness.
|
||||
</div>
|
||||
|
||||
<p>Each tab runs its own reader thread with a bounded channel, so one tab's heavy output never blocks the UI thread. The wgpu backend renders the full terminal grid with an instanced quad pipeline (one draw call per frame) and a lazily-uploaded glyph atlas.</p>
|
||||
|
||||
<h2>Distro support</h2>
|
||||
|
||||
<p>The <code>sysprep.sh</code> script auto-detects your distro and installs the right packages:</p>
|
||||
|
||||
<table>
|
||||
<thead><tr><th>Distro family</th><th>Package manager</th></tr></thead>
|
||||
<tbody>
|
||||
<tr><td>Arch, Manjaro, EndeavourOS, Garuda, Artix</td><td><code>pacman</code></td></tr>
|
||||
<tr><td>Debian, Ubuntu, Pop!_OS, Mint, Elementary, Kali, Raspbian</td><td><code>apt</code></td></tr>
|
||||
<tr><td>Fedora, RHEL, Rocky, Alma, CentOS, Amazon Linux</td><td><code>dnf</code></td></tr>
|
||||
<tr><td>openSUSE, SUSE Linux Enterprise</td><td><code>zypper</code></td></tr>
|
||||
<tr><td>Void</td><td><code>xbps-install</code></td></tr>
|
||||
<tr><td>Alpine</td><td><code>apk</code></td></tr>
|
||||
<tr><td>NixOS</td><td>prints a <code>shell.nix</code> recipe</td></tr>
|
||||
<tr><td>SourceMage</td><td><code>cast</code></td></tr>
|
||||
<tr><td>Gentoo, Funtoo</td><td><code>emerge</code></td></tr>
|
||||
</tbody>
|
||||
</table>
|
||||
|
||||
<p>One command from a fresh checkout to a system-installed binary:</p>
|
||||
|
||||
<pre><code>sudo ./install.sh --sysprep</code></pre>
|
||||
|
||||
<h2>The architecture in one paragraph</h2>
|
||||
|
||||
<p>The app owns a <code>TerminalManager</code> (vec of <code>TerminalTab</code>s, each with a PTY + an <code>alacritty_terminal::Term</code> + a reader thread), an <code>InputRouter</code> (translates key chords to <code>Command</code>s or raw bytes), a <code>PaletteState</code> (command palette), and a <code>SessionState</code> (mouse, selection, hyperlinks, images). The renderer is a trait — <code>TuiRenderer</code> (ratatui + crossterm) is the default; <code>WgpuRenderer</code> (Vulkan/GL) and <code>SoftRenderer</code> (CPU raster via tiny-skia) are opt-in. Auto-detect probes in priority order: wgpu → soft → tui. Every backend translates its native events into <code>AppEvent</code> at the renderer boundary, so the app loop is fully backend-agnostic.</p>
|
||||
|
||||
<h2>Try it</h2>
|
||||
|
||||
<pre><code># Clone the repo, then:
|
||||
./scripts/sysprep.sh # install build deps for your distro
|
||||
./scripts/build.sh # cargo build --release --features lua,images,gpu
|
||||
./target/release/rs-mrxvt # run it
|
||||
|
||||
# Or in one shot:
|
||||
sudo ./install.sh --sysprep</code></pre>

# rs-mrxvt Quick Start
|
||||
|
||||
A 60-second tour from zero to running terminal. For full docs see
|
||||
[`README.md`](../README.md).
|
||||
|
||||
## 1. Install build deps
|
||||
|
||||
```bash
|
||||
./scripts/sysprep.sh
|
||||
```
|
||||
|
||||
This auto-detects your distro and installs Rust + the system libraries
|
||||
needed for the GPU backends. Works on Arch, Debian/Ubuntu, Fedora,
|
||||
openSUSE, Void, Alpine, NixOS, SourceMage, and Gentoo.
|
||||
|
||||
Skip GPU deps if you only want the TUI backend:
|
||||
|
||||
```bash
|
||||
./scripts/sysprep.sh --no-gpu
|
||||
```
|
||||
|
||||
## 2. Build
|
||||
|
||||
```bash
|
||||
./scripts/build.sh
|
||||
```
|
||||
|
||||
Defaults to release mode with all features (`lua,images,gpu`). For a
|
||||
barebones TUI-only build:
|
||||
|
||||
```bash
|
||||
./scripts/build.sh --no-features
|
||||
```
|
||||
|
||||
For a debug build while hacking:
|
||||
|
||||
```bash
|
||||
./scripts/build.sh --debug
|
||||
```
|
||||
|
||||
## 3. Run
|
||||
|
||||
```bash
|
||||
./target/release/rs-mrxvt
|
||||
```
|
||||
|
||||
You should see a bash shell in a tabbed terminal. Try these:
|
||||
|
||||
| Keys | What happens |
|
||||
|-------------------|-------------------------------------------|
|
||||
| `Alt+N` | New bash tab |
|
||||
| `Alt+Z` | New zsh tab |
|
||||
| `Alt+1` … `Alt+0` | Jump to tab 1..10 |
|
||||
| `Alt+Left/Right` | Shuffle to previous/next tab |
|
||||
| `Alt+Shift+X` | Close the focused tab |
|
||||
| `Ctrl+Shift+I` | Toggle input broadcasting to all tabs |
|
||||
| `Ctrl+Shift+P` | Open the command palette (fuzzy search) |
|
||||
| `Ctrl+Shift+T` | New tab (classic mrxvt binding) |
|
||||
| `Ctrl+Shift+W` | Close tab (classic mrxvt binding) |
|
||||
|
||||
## 4. Broadcasting (the killer feature)
|
||||
|
||||
Open three tabs and broadcast keystrokes to all of them:
|
||||
|
||||
```bash
|
||||
./target/release/rs-mrxvt -n 3 -j
|
||||
```
|
||||
|
||||
Now anything you type goes to every tab simultaneously. The status bar
|
||||
turns red and shows `● BROADCAST:All`. Toggle it off with `Ctrl+Shift+I`.
|
||||
|
||||
For tagged-group broadcasting (only some tabs receive input):
|
||||
|
||||
```bash
|
||||
./target/release/rs-mrxvt -n 5 -g web
|
||||
```
|
||||
|
||||
All 5 tabs are tagged "web". Use `ToggleBroadcastGroup("web")` from the
|
||||
command palette to broadcast only to them.
|
||||
|
||||
## 5. Pick a theme
|
||||
|
||||
Edit `~/.config/rs-mrxvt/config.toml`:
|
||||
|
||||
```toml
|
||||
[ui]
|
||||
theme = "tokyo-night" # or: mrxvt, gruvbox, dracula, solarized-dark, solarized-light
|
||||
```
|
||||
|
||||
Or use Lua for dynamic theming (`~/.config/rs-mrxvt/config.lua`, requires
|
||||
`--features lua`):
|
||||
|
||||
```lua
|
||||
local hour = tonumber(os.date("%H"))
|
||||
local theme = "mrxvt"
|
||||
if hour >= 20 or hour < 6 then
|
||||
theme = "tokyo-night"
|
||||
end
|
||||
|
||||
return {
|
||||
ui = { theme = theme },
|
||||
}
|
||||
```
|
||||
|
||||
## 6. Install system-wide
|
||||
|
||||
```bash
|
||||
sudo ./install.sh # /usr/local/bin/rs-mrxvt
|
||||
sudo ./install.sh /usr # /usr/bin/rs-mrxvt
|
||||
```
|
||||
|
||||
Or one-shot from a fresh checkout:
|
||||
|
||||
```bash
|
||||
sudo ./install.sh --sysprep # install deps + build + install
|
||||
```
|
||||
|
||||
## 7. Verify it works
|
||||
|
||||
```bash
|
||||
rs-mrxvt --version
|
||||
rs-mrxvt --help
|
||||
python3 scripts/stress_test.py --tabs 50 # 50-instance broadcast test
|
||||
```
|
||||
|
||||
## Next steps
|
||||
|
||||
- Read [`README.md`](../README.md) for the full feature list and config schema.
|
||||
- Read [`ARCHITECTURE.md`](../ARCHITECTURE.md) for the module layout.
|
||||
- Read [`CONTRIBUTING.md`](../CONTRIBUTING.md) if you want to hack on it.
|
||||
- File issues / PRs at the project repo.

"""
|
||||
rs-mrxvt stress harness — spawns N rs-mrxvt tabs in broadcast mode and verifies
|
||||
that input typed once is mirrored to every tab's PTY.
|
||||
|
||||
This is the "test_suite.py" referenced at the end of the original design chat.
|
||||
It uses only stdlib + the `mrxvt` library's public API via cargo-test FFI is
|
||||
NOT used — instead, we spawn the compiled `rs-mrxvt` binary with `--broadcast`
|
||||
and verify behavior through PTY inspection.
|
||||
|
||||
Since the GUI binary can't be driven headlessly here, this script tests the
|
||||
underlying PTY plumbing directly by spawning subprocesses through Python's
|
||||
pty module and verifying broadcasting at the shell level. It's a smoke test
|
||||
for the "could I manage 50 servers simultaneously?" use case from the chat.
|
||||
|
||||
Usage:
|
||||
python3 scripts/stress_test.py [--tabs 50] [--timeout 30]
|
||||
|
||||
Requirements:
|
||||
- Python 3.10+
|
||||
- /bin/sh
|
||||
- (Optionally) rs-mrxvt binary for an integration smoke check

//! Lua-backed config source.
|
||||
//!
|
||||
//! Compiles only with `--features lua`. Implements [`ConfigSource`] by
|
||||
//! evaluating a Lua script that returns a config table.
|
||||
//!
|
||||
//! ## Lua config format
|
||||
//!
|
||||
//! The script must `return` a table with the same shape as the TOML config:
|
||||
//!
|
||||
//! ```lua
|
||||
//! return {
|
||||
//! terminal = {
|
||||
//! cols = 120,
|
||||
//! rows = 40,
|
||||
//! shell = "/bin/zsh",
|
||||
//! },
|
||||
//! ui = {
|
||||
//! theme = "tokyo-night",
|
||||
//! always_show_tabs = true,
|
||||
//! },
|
||||
//! default_profile = "default",
|
||||
//! profiles = {
|
||||
//! default = { command = {"zsh"}, cwd = "/home/user" },
|
||||
//! web = { command = {"ssh", "user@web-01"}, tag = "web" },
|
||||
//! },
|
||||
//! macros = {
|
||||
//! ["Ctrl+Shift+R"] = "ResetTerminal",
|
||||
//! },
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! ## Why Lua?
|
||||
//!
|
||||
//! TOML is great for static config but can't express logic. Lua gives users:
|
||||
//! - Conditional config ("if it's after 8pm, use midnight theme")
|
||||
//! - Programmable macros (functions, not just command names)
|
||||
//! - Hot-reload (re-eval the script on file change)
|
||||
//! - Access to environment vars and time
|
||||
//!
|
||||
//! ## Example: time-based theme
|
||||
//!
|
||||
//! ```lua
|
||||
//! local hour = tonumber(os.date("%H"))
|
||||
//! local theme = "mrxvt"
|
||||
//! if hour >= 20 or hour < 6 then
|
||||
//! theme = "tokyo-night"
|
||||
//! end
|
||||
//!
|
||||
//! return {
|
||||
//! ui = { theme = theme },
|
||||
//! terminal = { cols = 120, rows = 40 },
|
||||
//! }
|
||||
//! ```

//! Hot-reload config watcher.
|
||||
//!
|

//! Watches the config file for changes (via polling — no `inotify` dependency
|
||||
//! for distro-agnosticism) and re-evaluates it on save. The new [`Config`]
|
||||
//! is delivered through a channel; the main loop picks it up on the next
|
||||
//! tick.
|
||||
//!
|
||||
//! ## Why polling?
|
||||
//!
|
||||
//! `notify` crate pulls in `inotify` on Linux, `kqueue` on BSD, and
|
||||
//! ReadDirectoryChangesW on Windows. Each adds platform-specific deps.
|

//! For a single config file, polling every 2s is cheap (~0% CPU) and works
|
||||
//! everywhere.
|
||||
//!
|
||||
//! ## What gets applied
|
||||
//!
|
||||
//! - `ui.*` (theme, tabbar height, focus model)
|
||||
//! - `terminal.scrolling_history` (affects new tabs only)
|
||||
//! - `profiles.*` (used when opening new tabs)
|
||||
//! - `macros.*`
|
||||
//! - `transparency.*`
|
||||
//!
|
||||
//! What does NOT get applied mid-run:
|
||||
//! - `terminal.cols/rows` — would require resizing the active terminal
|
||||
//! - `default_profile` — affects only new tabs anyway
|
||||
//! - Currently open tabs keep their original shells/cwds

//! OSC 8 hyperlink support.
|
||||
//!
|
||||
//! Implements the [OSC 8 escape sequence](https://gist.github.com/egmontkov/eb114294efbcd5adb1944c9842f0ec18)
|
||||
//! for inline hyperlinks. Programs like `ls` (with `--hyperlink=auto`),
|
||||
//! `gcc`, and various TUI file managers use this to make URLs and file
|
||||
//! paths clickable.
|
||||
//!
|
||||
//! ## Format
|
||||
//!
|
||||
//! ```text
|
||||
//! ESC ] 8 ; <params> ; <URI> ST ← start hyperlink
|
||||
//! ... clickable text ...
|
||||
//! ESC ] 8 ; ; ST ← end hyperlink
|
||||
//! ```
|
||||
//!
|
||||
//! `<params>` is a semicolon-separated list of `key=value` pairs. The
|
||||
//! most common are:
|
||||
//! - `id=<id>` — group consecutive cells into one logical link
|
||||
//! - `title=<text>` — tooltip text
|
||||
//!
|
||||
//! ## How it works
|
||||
//!
|
||||
//! The PTY stream is scanned for OSC 8 sequences. When found, we record
|
||||
//! the `(start_cell, end_cell, uri, id)` tuple in a [`HyperlinkStore`].
|
||||
//! The renderer queries the store when drawing cells; if a cell has a
|
||||
//! hyperlink, it can be styled differently (underline, hover color) and
|
||||
//! mouse clicks can resolve to the URI.
|
||||
//!
|
||||
//! ## Status
|
||||
//!
|
||||
//! Pure parser module. The renderer integration (drawing underlines on
|
||||
//! hyperlinked cells, mouse-click hit-testing) is the next step.

//! Image protocol support (Sixel + iTerm2 inline images).
|
||||
//!
|
||||
//! Compiles only with `--features images`. Adds the ability to display
|
||||
//! inline images in the terminal, as used by `ranger`, `neofetch`, `chafa`,
|
||||
//! `viu`, and other TUI image viewers.
|
||||
//!
|
||||
//! ## Supported protocols
|
||||
//!
|
||||
//! - **iTerm2 inline images**: `ESC ] 1337 ; File = ... : <base64> ST`
|
||||
//! The most common modern protocol, supported by iTerm2, WezTerm, Kitty,
|
||||
//! and others.
|
||||
//! - **Sixel**: `DCS q ... ST` — the older DEC protocol, still used by
|
||||
//! `mlterm`, `xterm` (with `-ti vt340`), and some embedded terminals.
|
||||
//!
|
||||
//! ## Implementation
|
||||
//!
|
||||
//! Image data is parsed out of the PTY stream and stored in an [`ImageStore`]
|
||||
//! keyed by the cell range it occupies. The renderer queries the store when
|
||||
//! drawing cells; if a cell has an image, the renderer composites the image
|
||||
//! pixels instead of (or in addition to) the cell's text.
|
||||
//!
|
||||
//! For the MVP, images are stored as RGBA buffers and rendered as cell-sized
|
||||
//! quads. Proper aspect-ratio preservation and scrolling are deferred.

//! Mouse event types and SGR mouse encoding.
|
||||
//!
|
||||
//! The classic mrxvt supported several mouse modes (X10, X11 normal, X11
|
||||
//! SGR-1006). This module defines the backend-agnostic mouse event type and
|
||||
//! the SGR encoder that translates mouse events into escape sequences for
|
||||
//! the child process.
|
||||
//!
|
||||
//! ## Mouse modes
|
||||
//!
|
||||
//! Programs request mouse reporting via DECSET escape sequences:
|
||||
//! - `?9h` — X10 (click only, no modifiers, no release)
|
||||
//! - `?1000h` — X11 normal (press/release + motion-with-button)
|
||||
//! - `?1002h` — X11 motion (all motion events, even with no button)
|
||||
//! - `?1003h` — all motion (no button needed)
|
||||
//! - `?1006h` — SGR-1006 encoding (extends the above with bigger coords
|
||||
//! and explicit press/release markers)
|
||||
//!
|
||||
//! The terminal keeps a `MouseMode` bitfield; the renderer translates raw
|
||||
//! mouse events into [`MouseEvent`]s and asks the encoder whether to send
|
||||
//! them to the child.
|
||||
//!
|
||||
//! ## Selection
|
||||
//!
|
||||
//! When mouse reporting is OFF, mouse events are interpreted locally as
|
||||
//! text selection: click-drag selects, release copies to clipboard. This
|
||||
//! module exposes a [`Selection`] state machine that renderers can drive.

|
||||
//! Sixel image protocol parser.
|
||||
//!
|
||||
//! Sixel is an old DEC image format that pre-dates the modern PNG/JPEG era.
|
||||
//! It's still used by `mlterm`, `xterm -ti vt340`, and various embedded
|
||||
//! terminals. The format is a sequence of escape codes that describe a
|
||||
//! raster image as runs of six-pixel-tall vertical strips ("sixels").
|
||||
//!
|
||||
//! ## Format
|
||||
//!
|
||||
//! Sixel data is sent inside a DCS (Device Control String):
|
||||
//! ```text
|
||||
//! DCS q <params> <sixel-data> ST
|
||||
//! ```
|
||||
//! - `DCS` = `ESC P` (0x1b 0x50)
|
||||
//! - `q` is the Sixel command introducer
|
||||
//! - `<params>` are semicolon-separated `key=val` pairs
|
||||
//! - `<sixel-data>` is a mix of:
|
||||
//! - `?` repeat count (e.g. `!10?` = repeat 10 times)
|
||||
//! - `#` color register selection (e.g. `#0` = use color 0)
|
||||
//! - `#N;r;g;b` define color N as r,g,b (0..100)
|
||||
//! - `!N<char>` repeat character N times
|
||||
//! - `$` carriage return (move to start of current line)
|
||||
//! - `-` new line of sixels
|
||||
//! - chars `?` (0x3f, 0b000000) to `~` (0x7e, 0b111111): 6 pixels high
|
||||
//! - `ST` = `ESC \` (0x1b 0x5c)
|
||||
//!
|
||||
//! ## Status
|
||||
//!
|
||||
//! This module parses Sixel data into an RGBA buffer. It compiles only with
|
||||
//! `--features images` (reuses [`crate::images::InlineImage`] for storage).

//! True-color theme presets.
|
||||
//!
|
||||
//! Each theme defines 18 colors: the 16 ANSI colors (0-15), plus a
|
||||
//! foreground, background, and cursor color. Themes are applied by the
|
||||
//! renderers when translating `alacritty_terminal`'s `NamedColor` enum
|
||||
//! into actual RGB values.
|
||||
//!
|
||||
//! ## Built-in presets
|
||||
//!
|
||||
//! - `mrxvt` — classic green-on-black (the original).
|
||||
//! - `tokyo-night` — Toki Night, a popular dark theme.
|
||||
//! - `gruvbox` — Gruvbox, warm retro colors.
|
||||
//! - `dracula` — Dracula, dark purple.
|
||||
//! - `solarized-dark` — Solarized Dark.
|
||||
//! - `solarized-light` — Solarized Light.
|
||||
//!
|
||||
//! ## Custom themes
|
||||
//!
|
||||
//! Users can define custom themes in TOML:
|
||||
//!
|
||||
//! ```toml
|
||||
//! [theme.custom]
|
||||
//! bg = "#1a1b26"
|
||||
//! fg = "#a9b1d6"
|
||||
//! cursor = "#c0caf5"
|
||||
//! black = "#15161e"
|
||||
//! red = "#f7768e"
|
||||
//! green = "#9ece6a"
|
||||
//! yellow = "#e0af68"
|
||||
//! blue = "#7aa2f7"
|
||||
//! magenta = "#bb9af7"
|
||||
//! cyan = "#7dcfff"
|
||||
//! white = "#a9b1d6"
|
||||
//! bright_black = "#414868"
|
||||
//! bright_red = "#ff7a93"

//! bright_green = "#b9f27c"

//! Backend selection: which `Renderer` should we use?
|
||||
//!
|
||||
//! Selection happens at startup, in this order:
|
||||
//!
|
||||
//! 1. **CLI flag** (`--backend {auto,tui,wgpu,soft}`) — explicit override.
|
||||
//! 2. **`MRXVT_BACKEND` env var** — same effect, useful for tests/wrappers.
|
||||
//! 3. **Auto-detect** — structured GPU probe → softbuffer → TUI.
|
||||
//!
|
||||
//! ## GPU detection
|
||||
//!
|
||||
//! When the `gpu` feature is enabled, auto-detect runs [`gpu_detect::GpuDetect`]
|
||||
//! which probes each wgpu backend (Vulkan → Metal → DX12 → GL), logs what it
|
||||
//! finds, and records *why* each step succeeded or failed. The full probe
|
||||
//! result is stored in [`LAST_GPU_PROBE`] so `--gpu-info` can print it later.
|
||||
//!
|
||||
//! ## The "VESA mode" fallback
|
||||
//!
|
||||
//! Classic VESA VBE was a CPU-driven linear framebuffer with no acceleration.
|
||||
//! The modern equivalent is [`softbuffer`](https://crates.io/crates/softbuffer)
|
||||
//! (a CPU pixel buffer that the compositor displays) paired with
|
||||
//! [`tiny-skia`](https://crates.io/crates/tiny-skia) for rasterization.
|
||||
//!
|
||||
//! This is the third tier in our chain: when no GPU is available but a
|
||||
//! display server exists, the softbuffer renderer gives you a real window
|
||||
//! with software-rendered glyphs. It's slower than wgpu but works on any
|
||||
//! hardware — including the kind of retro box where you'd still be running
|
||||
//! VESA drivers.

//! Per-tab fading state.
|
||||
//!
|
||||
//! Implements the classic mrxvt feature where inactive tabs are dimmed to
|
||||
//! keep focus on the active tab. Each tab has a `target_fading` (0.0 = active,
|
||||
//! 1.0 = fully faded) and a `current_fading` that lerps toward the target
|
||||
//! each frame, producing a smooth ~150ms transition instead of a snap.
|
||||
//!
|
||||
//! ## Usage
|
||||
//!
|
||||
//! The renderers (wgpu, softbuffer) read this state per-tab and apply it as
|
||||
//! a brightness multiplier on the cell colors before drawing.
|
||||
//!
|
||||
//! ## Lerp math
|
||||
//!
|
||||
//! ```text
|
||||
//! current_fading += (target_fading - current_fading) * lerp_speed * dt
|
||||
//! ```
|
||||
//!
|
||||
//! With `lerp_speed = 10.0` and `dt = 1/60`, the fade completes in ~150ms.

|

|
||||
//! Structured GPU detection for the wgpu backend.
|
||||
//!
|
||||
//! Instead of a bare `bool`, this module probes the system and returns a
|
||||
//! [`GpuProbeResult`] that tells you *what* was found (adapter name, backend
|
||||
//! type, limits) and *why* each step succeeded or failed. Every probe step
|
||||
//! logs a clear message so the user can see exactly what the fallback chain
|
||||
//! is doing at startup.
|
||||
//!
|
||||
//! ## Usage
|
||||
//!
|
||||
//! ```ignore
|
||||
//! let result = GpuDetect::probe();
|
||||
//! match result {
|
||||
//! GpuProbeResult::Available { adapter_info, backend, .. } => {
|
||||
//! log::info!("using GPU: {} via {}", adapter_info.name, backend);
|
||||
//! }
|
||||
//! GpuProbeResult::Unavailable { reasons } => {
|
||||
//! log::warn!("no GPU: {}", reasons.join("; "));
|
||||
//! }
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! ## Fallback semantics
|
||||
//!
|
||||
//! The probe tries backends in this order (configurable via [`GpuDetectOptions`]):
|
||||
//! 1. **Vulkan** — best performance on Linux/BSD.
|
||||
//! 2. **Metal** — native on macOS.
|
||||
//! 3. **DX12** — native on Windows.
|
||||
//! 4. **GL** — broadest compatibility (works on Mesa software, llvmpipe).
|
||||
//!
|
||||
//! If all fail, the result is `Unavailable` with a list of reasons.
|
||||
//! The caller (the backend selection chain) then falls through to
|
||||
//! softbuffer → TUI.

//! Softbuffer renderer — CPU rasterization, the modern VESA mode.
|

//!
|

//! When wgpu isn't available (no Vulkan, no GL, ancient hardware), this
|
||||
//! backend opens a window via `winit` and renders to a CPU pixel buffer
|
||||
//! via `softbuffer`. Text is rasterized through the shared [`glyph::GlyphCache`]
|

//! and composited into a `tiny-skia::Pixmap`, then blitted to the softbuffer
|

//! surface.
|
||||
//!
|
||||
//! ## Status: functional (text rendering works)
|
||||
//!
|
||||
//! Compiles only with `--features gpu`. Renders the active terminal grid:
|
||||
//! - Tab bar at the top
|
||||
//! - Terminal cells (text + colors)
|

//! - Status bar at the bottom (broadcast indicator)
|

//!
|
||||
//! ## Why this exists
|
||||
//!
|
||||
//! Classic VESA VBE was a CPU-driven linear framebuffer with no GPU
|
||||
//! acceleration. It worked on any VGA card because the CPU did everything.
|
||||
//! `softbuffer` + `tiny-skia` + `ab_glyph` is the modern equivalent: works
|
||||
//! on any compositor that speaks Wayland or X11, no GPU driver required.

|

|
||||
|
||||
//! Pseudo-transparency + tinting state.
|
||||
//!
|
||||
//! Implements the classic mrxvt `-tint` and `-sh` (shading) flags in a
|
||||
//! modern, shader-driven way. The state lives here; the wgpu backend
|
||||
//! consumes it via the [`TransparencyUniforms`] struct and the softbuffer
|
||||
//! backend reads it directly when compositing.
|
||||
//!
|
||||
//! ## Classic mrxvt semantics
|
||||
//!
|
||||
//! - `-tint <color>`: tint the background with the given color (multiply).
|
||||
//! - `-sh <value>`: shading amount, 0..100 (higher = darker).
|
||||
//! - `-bg <image>`: load a background image (root-pixmap in old mrxvt;
|
||||
//! compositor screenshot or static image in 2026).
|
||||
//!
|
||||
//! ## Modern implementation
|
||||
//!
|
||||
//! True transparency requires the compositor to blend the window with what's
|
||||
//! behind it. On Wayland this means using the `wlr-layer-shell` protocol
|
||||
//! (which the winit backend doesn't currently expose). For the MVP, we
|
||||
//! support:
|
||||
//!
|
||||
//! - **Static background image**: the user provides a path via `-bg`; we
|
||||
//! load it, upload it as a wgpu texture, and the shader samples it for
|
||||
//! each cell's background instead of using the cell's bg color directly.
|
||||
//! - **Tinting**: the shader multiplies the sampled background by the tint
|
||||
//! color before drawing text on top.
|
||||
//! - **Shading (opacity)**: the shader reduces the alpha of the final
|
||||
//! pixel, letting the desktop show through where the compositor supports it.
|
||||
//!
|
||||
//! ## Config
|
||||
//!
|
||||
//! In `config.toml`:
|
||||
//!
|
||||
//! ```toml
|
||||
//! [transparency]
|
||||
//! enabled = true
|
||||
//! tint = "#004080" # blue tint
|
||||
//! opacity = 0.85 # 1.0 = opaque, 0.0 = fully transparent
|
||||
//! background_image = "/path/to/wallpaper.png"
|
||||
//! ```
|
||||
//!
|
||||
//! In Lua config:
|
||||
//!
|
||||
//! ```lua
|
||||
//! return {
|
||||
//! transparency = {
|
||||
//! enabled = true,
|
||||
//! tint = "#004080",
|
||||
//! opacity = 0.85,
|
||||
//! },
|
||||
//! }

//! wgpu renderer — full GPU acceleration via Vulkan or GL.
|
||||
//!
|
||||
//! Top tier of the backend fallback chain. Renders the terminal grid using:
|
||||
//! - An instanced quad pipeline (one instance per cell)
|
||||
//! - A glyph atlas texture (uploaded from [`glyph::GlyphCache`])
|
||||
//! - WGSL shaders (see [`shaders::SHADER_SOURCE`])
|
||||
//!
|
||||
//! ## Status: functional (text rendering works on Vulkan/GL)
|
||||
//!
|
||||
//! Compiles only with `--features gpu`. Each frame:
|
||||
//! 1. Reads the active tab's `alacritty_terminal::Term` grid
|
||||
//! 2. Builds an instance buffer (one instance per visible cell)
|
||||
//! 3. Re-uploads the glyph atlas texture if new glyphs were rasterized
|
||||
//! 4. Draws the instances with the WGSL pipeline
|
||||
//!
|
||||
//! ## Build requirements
|
||||
//!
|
||||
//! Debian/Ubuntu: `apt install libvulkan-dev libwayland-dev libxkbcommon-dev`
|
||||
//! Arch: `pacman -S vulkan-headers wayland-protocols libxkbcommon`
|
||||
//! Fedora: `dnf install vulkan-headers wayland-devel libxkbcommon-devel`
