## :wave: Hello World
```smalltalk
Module import: '@gest/common', for: #{#identity => #id}.
args := Env args asArray.
name := args index?: 1.
"If there is a name, use that name, if not, default to World."
name := name nil? ifFalse: id, else: 'World'.
Module
export: [ Io printLn: 'Hello ' ++ name ++ '!'. ],
as: #main.
```
## :rocket: Getting started
Requirements: [premake](https://premake.github.io/), [uv](https://docs.astral.sh/uv/)
1. Clone the repo.
```console
$ git clone https://github.com/kaiserthe13th/gest.git
Cloning into 'gest'...
done.
$ cd gest
```
2. Set up the environment using premake.
```console
premake5 prepare
```
3. You can play around and compile with premake.
```console
$ premake5 vs2022/gmake2 etc.
$ cd build
$ msbuild /p:Configuration=StaticDebug ...
or
$ make config=staticdebug_bits64
```
> [!TIP] Use the `--test` flag on premake to get tests compiled.
## :handshake: Contributor's Guide
### :art: Code Style
We use code formatting tools for code styling, on top of a small [style guide](CODE_STYLE.md) for things that tools can't cover.
- For C, use [clang-format](https://clang.llvm.org/docs/ClangFormat.html).
- For Python, use [ruff](https://docs.astral.sh/ruff/).
### :test_tube: Testing
1. Build testing build.
```console
$ premake5 vs2022/gmake2 --test
$ cd build
$ ...
```
2. Run the test by running the generate gest-test executable.
### :scroll: License Linting
We use a tool called xg for checking licensing of our files. Please use the tool and ensure all files are licensed.
You can easily use it via premake with:
```console
$ premake5 xg
```
## :balance_scale: Licensing
The project uses the Apache 2.0 License with the LLVM Exception for most of its files. However, some files use the Unicode license for their data.
See [LICENSE](./LICENSE), and [NOTICE.xg](NOTICE.xg).
