# Fuzzy Ruby Server

A Ruby language server designed to stay performant for large codebases. A full-text search backend gives fast, but fuzzy search results that closely approximates the behaviour of Ruby.

## Installation

The workspace and gems will be indexed automatically after installing:

#### VSCode
**1.** Install the `Fuzzy Ruby Server` extension from the VSCode Marketplace.

**2.** Activate the extension by reloading VSCode and navigating to any `.rb` file.

#### Neovim
**1.** See the nvim [config example here](https://github.com/pheen/fuzzy_ruby_server/wiki/Neomvim-Install).

 
## Features

### Definitions
Peek or go to the definition of a variable, method, class, or module. If multiple definitions are found they will all be returned. Results are sorted by score so the first result automatically shown will be the closest match.

- Cmd: `Go to Definition`
- Keybinds:
- `f12`
- `cmd + click`
- **Tip:** Enable the VSCode setting `Workbench > Editor: Reveal If Open`

## Contributing
- Update the `command` path in `extension.ts` to point to your local working directory. Target release as it's necessary or indexing is too slow.
- E.g., `command = "/Users//dev/fuzzy_ruby_vscode_client/target/release/fuzzy";`.
- Run `yarn run esbuild` to compile `extension.ts`.
- Make Rust changes in `src`, then `cargo build --release`.
- Hit `F5` in VSCode to run a the extension in a new VSCode window.
- Make a pull request with your changes. Thank you!

 
## Publishing
- Build an Apple Intel release binary:
```
cargo build --target x86_64-apple-darwin
```

- Build an Apple Silicon binary:
```
cargo build --release --target=aarch64-apple-darwin
```

- Build a Linux binary:
```
brew tap messense/macos-cross-toolchains
brew install x86_64-unknown-linux-gnu

CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_LINKER=x86_64-unknown-linux-gnu-gcc cargo build --release --target=x86_64-unknown-linux-gnu
```

- Copy the binaries to `bin/`

- Delete the `target` directory or the `.vsix` package will be huge

- `vsce package`

- Upload the new package
