Kumitateru

Kumitateru is a build system for Garmin ConnectIQ, written in Rust.

It is ALPHA software, be aware

Project structure

The basic directory structure looks like this: ├── id_rsa_garmin.der ├── kumitateru ├── package.toml ├── resources │   ├── drawables │   │   ├── drawables.xml │   │   └── launcher_icon.png │   ├── fonts │   │   └── fenix5 │   ├── layouts │   ├── menus │   ├── settings │   └── strings │   └── main │   └── strings.xml └── src

Build config

Build config sits in the root of the project, and named package.toml. It looks like this:

```toml [package] nameres = "@Strings.AppName" iconresource = "@Drawables.LauncherIcon" main_class = "MyApp"

Currently here for the future, exactly for supporting libraries(barrels) as projects, not only apps.

packagetype = "app" apptype = "watch-app" min_sdk = "1.2.0"

This property is for setting the SDK, which will be used to build the app

target_sdk = "4.0.4"

[package_meta] name = "MyApp" id = "app-id" version = "1.0.0" devices = ["fenix6xpro"] permissions = ["Background"] languages = ["eng"]

[build] signingkey = "idgarmin_sign.der"

This will be, again, for future. Will be used for code analysis, like possible places of crash, bad design, and much more

codeanalysisonbuild = false typechecklevel = 0 # Type checking, which was introduced in CIQ 4.0.0. Levels: 0: disable, 1: gradual, 2: informative, 3: strict compilerargs = "" # If you want some custom parameters, place them here

[dependencies] "simple-barrel" = ["0.1.0", "simple-barrel-0.1.0.barrel"] # The second entry is a path to the barrel inside of dependencies folder. ```

For now Kumitateru does not support external dependencies(or barrels, as Garmin calls them), but I will figure out later how to add them, specifically when i will learn the full structure of Connect IQ manifest and monkey.jungle.

Using the build system

Basic build command is ./kumitateru build, which compiles the app in .iq format. To build for a specific device, run ./kumitateru build --target <device>. To build for all devices in .prg, you run ./kumitateru build --target all.
