## Installation
A [justfile](./justfile) is included by default for the [casey/just][just] command runner.
-`just` builds the application with the default `just build-release` recipe
-`just run` builds and runs the application
-`just install` installs the project into the system
-`just vendor` creates a vendored tarball
-`just build-vendored` compiles with vendored dependencies from that tarball
-`just check` runs clippy on the project to check for linter warnings
-`just check-json` can be used by IDEs that support LSP
## Translators
[Fluent][fluent] is used for localization of the software. Fluent's translation files are found in the [i18n directory](./i18n). New translations may copy the [English (en) localization](./i18n/en) of the project, rename `en` to the desired [ISO 639-1 language code][iso-codes], and then translations can be provided for each [message identifier][fluent-guide]. If no translation is necessary, the message may be omitted.
## Packaging
If packaging for a Linux distribution, vendor dependencies locally with the `vendor` rule, and build with the vendored sources using the `build-vendored` rule. When installing files, use the `rootdir` and `prefix` variables to change installation paths.
```sh
just vendor
just build-vendored
just rootdir=debian/noctua prefix=/usr install
```
It is recommended to build a source tarball with the vendored dependencies, which can typically be done by running `just vendor` on the host system before it enters the build environment.
## Developers
Developers should install [rustup][rustup] and configure their editor to use [rust-analyzer][rust-analyzer]. To improve compilation times, disable LTO in the release profile, install the [mold][mold] linker, and configure [sccache][sccache] for use with Rust. The [mold][mold] linker will only improve link times if LTO is disabled.
