-# Building Cagire
-
-## Quick Start
-
-```bash
-git clone https://git.raphaelforment.fr/BuboBubo/cagire
-cd cagire
-cargo build --release
-```
-
-The `doux` audio engine is fetched automatically from git. No local path setup needed.
-
-## Prerequisites
-
-**Rust** (stable toolchain): https://rustup.rs
-
-## System Dependencies
-
-### macOS
-
-```bash
-brew install cmake
-```
-
-cmake is required by `rusty_link` (Ableton Link C++ bindings). Xcode Command Line Tools provide the C++ compiler. CoreAudio and CoreMIDI are built-in. The desktop build needs no additional dependencies on macOS (Cocoa/Metal are provided by the system).
-
-### Linux (Debian/Ubuntu)
-
-```bash
-sudo apt install cmake g++ pkg-config libasound2-dev libjack-jackd2-dev
-```
-
-For the desktop build (egui/eframe), also install:
-
-```bash
-sudo apt install libgl-dev libxkbcommon-dev libx11-dev libxcursor-dev libxrandr-dev libxi-dev libwayland-dev
-```
-
-### Linux (Arch)
-
-```bash
-sudo pacman -S cmake gcc pkgconf alsa-lib jack2
-```
-
-For the desktop build:
-
-```bash
-sudo pacman -S libxkbcommon libx11 libxcursor libxrandr libxi wayland mesa
-```
-
-### Linux (Fedora)
-
-```bash
-sudo dnf install cmake gcc-c++ pkgconf-pkg-config alsa-lib-devel jack-audio-connection-kit-devel
-```
-
-For the desktop build:
-
-```bash
-sudo dnf install libxkbcommon-devel libX11-devel libXcursor-devel libXrandr-devel libXi-devel wayland-devel mesa-libGL-devel
-```
-
-### Windows
-
-Install Visual Studio Build Tools (MSVC) and CMake. Everything else is provided by the Windows SDK.
-
-## Build
-
-Terminal (default):
-
-```bash
-cargo build --release
-```
-
-Desktop (egui window):
-
-```bash
-cargo build --release --features desktop --bin cagire-desktop
-```
-
-Plugins (CLAP/VST3):
-
-```bash
-cargo xtask bundle cagire-plugins --release
-```
-
-The xtask alias is defined in `.cargo/config.toml` (committed). Plugin bundles are output to `target/bundled/`.
-
-## Run
-
-Terminal (default):
-
-```bash
-cargo run --release -- [OPTIONS]
-```
-
-Desktop (egui window):
-
-```bash
-cargo run --release --features desktop --bin cagire-desktop
-```

-macOS targets can only be built on macOS. Linux targets are cross-compiled via Docker (`cross`). Windows targets are cross-compiled natively via `cargo-xwin` (downloads Windows SDK + MSVC CRT headers, no Docker needed).
-
-### Prerequisites
-
-1. **Docker** + **cross** (Linux targets only): `cargo install cross --git https://github.com/cross-rs/cross`
-2. **cargo-xwin** (Windows target): `cargo install cargo-xwin` and `rustup target add x86_64-pc-windows-msvc`
-3. On macOS, add the Intel target: `rustup target add x86_64-apple-darwin`
-
-### Building Individual Targets
-
-```bash
-# Linux x86_64 (Docker)
-cross build --release --target x86_64-unknown-linux-gnu
-cross build --release --features desktop --bin cagire-desktop --target x86_64-unknown-linux-gnu
-
-# Linux aarch64 (Docker)
-cross build --release --target aarch64-unknown-linux-gnu
-cross build --release --features desktop --bin cagire-desktop --target aarch64-unknown-linux-gnu
-
-# Windows x86_64 (native, no Docker)
-cargo xwin build --release --target x86_64-pc-windows-msvc
-cargo xwin build --release --features desktop --bin cagire-desktop --target x86_64-pc-windows-msvc
-```
-
-### Building All Targets
-
-```bash
-# Interactive (prompts for platform/target selection):
-uv run scripts/build.py
-
-# Non-interactive:
-uv run scripts/build.py --platforms macos-arm64,linux-x86_64 --targets cli,desktop
-uv run scripts/build.py --all
-```
-
-Builds selected targets, producing binaries in `releases/`.
-
-Platform aliases: `macos-arm64`, `macos-x86_64`, `linux-x86_64`, `linux-aarch64`, `windows-x86_64`.
-Target aliases: `cli`, `desktop`, `plugins`.
-
-### Linux AppImage Packaging
-
-Linux releases ship as AppImages — self-contained executables that bundle all shared library dependencies (ALSA, JACK, X11, OpenGL). No runtime dependencies required. `build.py` handles AppImage creation automatically for Linux targets.
-
-### Notes
-
-- Custom Dockerfiles in `scripts/cross/` install the native libraries for Linux cross-compilation (ALSA, JACK, X11, cmake, libclang, etc.). `Cross.toml` maps each Linux target to its Dockerfile.
-- The first Linux cross-build per target downloads Docker base images and installs packages. Subsequent builds use cached layers.
-- Cross-architecture Docker builds (e.g. aarch64 on x86_64) run under QEMU emulation and are significantly slower.
-- Windows cross-compilation via `cargo-xwin` runs natively on the host (no Docker) and uses real Windows SDK headers, ensuring correct ABI and struct layouts.

CHANGELOG.md

@@ -2,237 +2,56 @@
 
 All notable changes to this project will be documented in this file.
 
-## [0.1.5]
-
-### Forth Language
-- **`at` reworked as a looping block**: `at` now captures all stack values as deltas, then re-executes its body once per delta. Closed by `.` (audio emit), `m.` (MIDI emit), or `done` (no emit). Each iteration gets independent nondeterministic rolls (e.g., `0 0.5 at kick snd 1 2 rand freq .` re-evaluates `kick snd 1 2 rand freq` at delta 0 and 0.5).
-- Removed `ArpList` type and `arp` word — arpeggio spreading is now handled by at-loops directly.
-
-### Added
-
-- Support i32/i16 sample formats at cpal boundary for ASIO compatibility
-
-### Fixed
-- Resolved value annotations deduplicated: nondeterministic ops inside at-loops now show only the last resolved value per span, instead of one annotation per iteration.
-- Audio input device name matching.
-
-## [0.1.4]
-
-### Breaking
-- **Doux v0.0.12**: removed Mutable Instruments Plaits modes (`modal`, `va`, `analog`, `waveshape`, `grain`, `chord`, `swarm`, `pnoise`, etc.). Native percussion models retained; new models added: `tom`, `cowbell`, `cymbal`.
-- Simplified effects/filter API: removed per-filter envelope parameters in favor of the universal `env` word.
-- Recording commands simplified: removed `/sound/` path segment from `rec`, `overdub`, `orec`, `odub`.
-
-### Forth Language
-- New modulation transition words: `islide` (swell), `oslide` (pluck), `pslide` (stair/stepped).
-- New `lpg` word (Low Pass Gate): pairs amplitude envelope with lowpass filter modulation.
-- New `inchan` word: select audio input channel by index.
-- New EQ frequency words: `eqlofreq`, `eqmidfreq`, `eqhifreq`.
-
-### UI / UX
-- Redesigned top bar: consolidated transport, tempo, bar:beat display with visual beat segments.
-- CPU meter with color-coded fill bar (green/yellow/red).
-
-### Engine
-- Audio input channel selection support.
-- Audio buffer sizing improved for multi-channel input.
-- MIDI output sends directly from dispatcher thread, bypassing UI-thread polling (~30x less jitter).
-
-### Packaging
-- CI migrated from GitHub Actions to Gitea Actions.
-- Removed WIX installer; Windows now distributed via zip and NSIS only.
-- Gitea Actions workflow for automatic website deployment.
-- Added LICENSE file.
-
-### Documentation
-- Extensive documentation updates reflecting doux v0.0.12 API changes across sources, filters, modulation, wavetable, and audio modulation docs.
-
-## [0.1.3]
-
-### Forth Language
-- New `stretch` word: pitch-independent time stretching via phase vocoder (e.g., `kick sound 2 stretch .` plays at half speed, same pitch).
-- Automatic default release time on sounds when none is explicitly set.
-
-### Engine
-- Sample-accurate timing: delta computation switched from float seconds to integer sample ticks, fixing precision issues.
-- Lock-free audio input buffer: replaced `Arc<Mutex<VecDeque>>` with `HeapRb` ring buffer.
-- Theme access optimized: `Rc<ThemeColors>` replaces deep cloning on every `get()`.
-- Dictionary keys cached in `App` to avoid repeated lock acquisitions during rendering.
-
-### Fixed
-- Realtime priority diagnostics: dedicated `warn_no_rt()` on Linux, lookahead widened from 20ms to 40ms when RT priority unavailable.
-- Float epsilon precision in delta/nudge zero-comparisons.
-- Windows build fixes for standalone and plugin targets.
-
-### Documentation
-- Time stretching usage guide added to `docs/engine/samples.md`.
-
-## [0.1.2]
-
-### Forth Language
-- Single-letter envelope aliases: `a` (attack), `d` (decay), `s` (sustain), `r` (release).
-- `sound` alias changed from `s` to `snd` (frees `s` for sustain).
-- New `partials` word: set number of active harmonics for additive oscillator.
-- Velocity parameter normalized to 0–1 float range (was 0–127 integer).
-
-### UI / UX
-- **Sample Explorer as dedicated page**: the side panel is now a full page (Tab key), with keyboard navigation (j/k, search with `/`, preview with Enter), replacing the old collapsible side panel.
-- **Pulsing armed-changes bar** on patterns page: staged play/stop/mute/solo changes shown in a launch bar with animated feedback ("c to launch").
-- Pulsing highlight on banks and patterns with staged changes.
-- Sample browser shows child count on collapsed folders and uses `+`/`-` tree icons.
-- File browser modal: shows audio file counts per directory, colored path segments, and hint bar.
-- Audio devices refreshed automatically when entering the Engine page.
-- Bank prelude field added to data model (foundation for bank-level Forth scripts).
-
-### Engine
-- Audio timing switched from float seconds to integer tick-based scheduling, improving timing precision.
-- Stream error handling refined: only `DeviceNotAvailable` and `StreamInvalidated` trigger device-lost recovery (non-fatal errors no longer restart the stream).
-- Step traces use `Arc` for cheaper cloning between threads.
-
-### Packaging
-- **Windows: NSIS installer** replaces cargo-wix MSI. Includes optional PATH registration, Start Menu shortcut, and proper Add/Remove Programs entry with uninstaller.
-- Improved Windows cross-compilation from Unix hosts (MinGW toolchain detection).
-- CI build timeouts increased to 60 minutes across all platforms.
-- Website download matrix updated.
-
-## [0.1.1]
-
-### Forth Language
-- `map` word: apply a quotation to each stack element (`1 2 3 ( 10 * ) map => 10 20 30`).
-- `loop` fix: now operates in steps instead of beats, uses `step_duration()` for correct timing.
-
-### Fixed
-- Crash on missing sample directories: sample path scanning now validates directories exist before scanning.
-- Audio channel minimum enforced to 2, preventing crash on devices reporting fewer channels.
-- Audio device disconnect: automatic stream restart when device is lost (terminal and desktop).
-- Live keys (e.g. `f` for fill) no longer trigger while searching in dictionary or help views.
-- Side panel always uses horizontal layout (removed broken vertical fallback for narrow terminals).
-
-### Changed
-- Runtime highlight enabled by default.
-
-### Packaging
-- Modular CI: split monolithic release workflow into per-platform builds (Linux, macOS, Windows, cross-compilation).
-- Separate CI workflows for CLAP/VST plugin builds (Linux, macOS, Windows, Raspberry Pi).
-- Windows MSI installer workflow fixes.
-- Website download matrix updated.
-

-### Features
+## Run
 
-- **Cagire's Forth**: a stack-based language made for live coding
+Terminal version:
-  - Forth has almost no syntax, only words, numbers and spaces. Very easy to learn for beginners, quite deep for experienced programmers.
+```
-  - Nondeterminism and generative: randomness, probabilities, patterns thought as first-class features.
+cargo run --release
-  - Quotations: code blocks `( ... )` that compose with probability, cycling, euclidean, and conditional words.
+```
-  - User-defined words: extend (or redefine) the language on the fly with `:name ... ;` definitions.
-  - Interactive documentation: built-in tutorials with runnable examples.
-- **Audio engine** (powered by [Doux](https://doux.livecoding.fr)):
-  - Synthesis: classic waveforms (saw, pulse, tri, sine), additive (up to 32 partials), FM (2-op, 3 algorithms), wavetables, 7-voice spread.
-  - Drum models: seven drum models with timbral morphing.
-  - Sampling: disk-loaded samples with slicing, looping, pitch tracking, wavetable mode, and live recording from engine output or line input.
-  - Filters: biquad LP/HP/BP and ladder filters. Filters can be modulated, stacked, etc.
-  - Effects: phaser, flanger, chorus, smear, distortion, wavefolder, wavewrapper, bitcrusher, sample-rate reduction, 3-band EQ, tilt EQ, Haas stereo.
-  - Bus effects: delay (standard, ping-pong, tape, multitap), two reverb engines (Dattorro plate, Vital Space), comb filter, feedback delay with LFO, sidechain compressor.
-  - Modulation: vibrato, AM, ring mod, audio-rate LFO, transitions, DAHDSR envelope modulation — all applicable to any parameter.
-- **Sequencing**: probabilities, patterns, euclidean structures, sub-step timing, pattern chaining and a lot more.
-- **MIDI**: receive or send MIDI messages across up to 4 inputs and 4 outputs.
-- **Ableton Link**: tempo and phase sync with any Link-enabled software or hardware.
-- **Cross-platform**: terminal and desktop interfaces on macOS, Linux, and Windows.

-# cagire-forth
-
-Stack-based Forth VM for the Cagire sequencer. Tokenizes, compiles, and executes step scripts to produce audio and MIDI commands.
-
-## Modules
-
-| Module | Description |
-|--------|-------------|
-| `vm` | Interpreter loop, `Forth::evaluate()` entry point |
-| `compiler` | Tokenization (with source spans) and single-pass compilation to ops |
-| `ops` | `Op` enum (~90 variants) |
-| `types` | `Value`, `StepContext`, shared state types |
-| `words/` | Built-in word definitions: `core`, `sound`, `music`, `midi`, `effects`, `sequencing`, `compile` |
-| `theory/` | Music theory lookups: `scales` (~200 patterns), `chords` (interval arrays) |
-
-## Key Types
-
-- **`Forth`** — VM instance, holds stacks and compilation state
-- **`Value`** — Stack value (int, float, string, list, quotation, ...)
-- **`StepContext`** — Per-step evaluation context (step index, tempo, variables, ...)
-- **`Op`** — Compiled operation; nondeterministic variants carry `Option<SourceSpan>` for tracing
-- **`ExecutionTrace`** — Records executed/selected spans and resolved values during evaluation

-TUI widget library and theme system for Cagire.
-
-## Widgets
-
-`category_list`, `confirm`, `editor`, `file_browser`, `hint_bar`, `lissajous`, `list_select`, `modal`, `nav_minimap`, `props_form`, `sample_browser`, `scope`, `scroll_indicators`, `search_bar`, `section_header`, `sparkles`, `spectrum`, `text_input`, `vu_meter`, `waveform`
-
-## Theme System
-
-The `theme/` module provides a palette-based theming system using Oklab color space.
-
-| Module | Description |
-|--------|-------------|
-| `mod` | `THEMES` array, `CURRENT_THEME` thread-local, `get()`/`set()` |
-| `palette` | `Palette` (14 fields), color manipulation helpers (`shift`, `mix`, `tint_bg`, ...) |
-| `build` | Derives ~190 `ThemeColors` fields from a `Palette` |
-| `transform` | HSV-based hue rotation for generated palettes |
-
-25 built-in themes.
-
-## Key Types
-
-- **`Palette`** — 14-field color definition, input to theme generation
-- **`ThemeColors`** — ~190 derived semantic colors used throughout the UI

 After selecting a sound source, you add parameters. Each parameter word takes a value from the stack and stores it in the command register:

 Parameters can appear in any order. They accumulate until you emit. You can clear the register using the `clear` word.
 
-## Global Parameters
-
-Use `all` to apply parameters globally. Global parameters persist across all patterns and steps until cleared with `noall`. They work both prospectively (before sounds) and retroactively (after sounds):
-
-```forth
-;; Prospective: set params before emitting
-500 lpf 0.5 verb all
-kick snd 60 note .      ;; gets lpf=500 verb=0.5
-hat snd 70 note .       ;; gets lpf=500 verb=0.5

-```forth
-;; Retroactive: patch already-emitted sounds
-kick snd 60 note .
-hat snd 70 note .
-500 lpf 0.5 verb all  ;; both outputs get lpf and verb

-Per-sound parameters override global ones:
-
-```forth
-500 lpf all
-kick snd 2000 lpf .     ;; lpf=2000 (per-sound wins)
-hat snd .               ;; lpf=500  (global)

-noall
-hat snd .               ;; no lpf

 ## Controlling Existing Voices
 
 You can emit without a sound name. In this case, no new voice is created. Instead, the parameters are sent to control an existing voice. Use `voice` with an ID to target a specific voice:
