# boilerplate for a rust language server powered by `tower-lsp`
## Introduction
This repo is a template for `tower-lsp`, a useful github project template which makes writing new language servers easier.
## Development using VSCode
1. `pnpm i`
2. `cargo build`
3. Open the project in VSCode: `code .`
4. In VSCode, press F5 or change to the Debug panel and click Launch Client.
5. In the newly launched VSCode instance, open the file `examples/test.nrs` from this project.
6. If the LSP is working correctly you should see syntax highlighting and the features described below should work.
> **Note**
>
> If encountered errors like `Cannot find module '/xxx/xxx/dist/extension.js'`
> please try run command `tsc -b` manually, you could refer https://github.com/IWANABETHATGUY/tower-lsp-boilerplate/issues/6 for more details
## A valid program in nano rust
```rust
fn factorial(x) {
// Conditionals are supported!
if x == 0 {
1
} else {
x * factorial(x - 1)
}
}
// The main function
fn main() {
let three = 3;
let meaning_of_life = three * 14 + 1;
print("Hello, world!");
print("The meaning of life is...");
if meaning_of_life == 42 {
print(meaning_of_life);
} else {
print("...something we cannot know");
print("However, I can tell you that the factorial of 10 is...");
// Function calling
print(factorial(10));
}
}
```
## Features
This repo use a language `nano rust` which first introduced by [ chumsky ](https://github.com/zesterer/chumsky/blob/master/examples/nano_rust.rs). Most common language feature has been implemented, you could preview via the video below.
- [x] InlayHint for LiteralType
- [x] semantic token
make sure your semantic token is enabled, you could enable your `semantic token` by
adding this line to your `settings.json`
```json
{
"editor.semanticHighlighting.enabled": true,
}
```
- [x] syntactic error diagnostic
