1//! # xtask — Cadmus build automation
2//!
3//! Centralises every build, test, lint, documentation, and release task for
4//! the Cadmus project as typed, testable Rust code that behaves identically
5//! in a local devenv shell and in GitHub Actions CI.
6//!
7//! ## Usage
8//!
9//! ```text
10//! cargo xtask <COMMAND> [OPTIONS]
11//! ```
12//!
13//! The `xtask` alias is configured in `.cargo/config.toml` so that
14//! `cargo xtask` works from any directory inside the workspace.
15//!
16//! ## Commands
17//!
18//! | Command | Description |
19//! |---------|-------------|
20//! | [`fmt`](tasks::fmt) | Check (or apply) `rustfmt` formatting |
21//! | [`clippy`](tasks::clippy) | Run `cargo clippy` across the feature matrix |
22//! | [`test`](tasks::test) | Run `cargo test` across the feature matrix |
23//! | [`build-kobo`](tasks::build_kobo) | Cross-compile for Kobo (ARM, Linux only) |
24//! | [`setup-native`](tasks::setup_native) | Build MuPDF and the C wrapper for native dev |
25//! | [`run-emulator`](tasks::run_emulator) | Run the Cadmus emulator (ensures prereqs are built) |
26//! | [`install-importer`](tasks::install_importer) | Install the Cadmus importer crate |
27//! | [`docs`](tasks::docs) | Build the full documentation portal |
28//! | [`download-assets`](tasks::download_assets) | Download static asset dirs from the latest release |
29//! | [`dist`](tasks::dist) | Assemble the Kobo distribution directory |
30//! | [`bundle`](tasks::bundle) | Package a `KoboRoot.tgz` ready for device installation |
31//! | [`ci`](tasks::ci) | CI-specific setup tasks (e.g. `install-doc-tools`) |
32//!
33//! ## Design
34//!
35//! Each command lives in its own module under [`tasks`].  The `tasks::util::cmd`
36//! helper wraps [`std::process::Command`] with consistent error reporting so
37//! every task fails fast with a clear message.  The `tasks::util::http` module
38//! provides pure-Rust download and archive helpers replacing `curl`, `wget`,
39//! `tar`, and `sha256sum` subprocess calls.
