# Haxe Language Server

[![CI](https://github.com/vshaxe/haxe-language-server/actions/workflows/main.yml/badge.svg)](https://github.com/vshaxe/haxe-language-server/actions/workflows/main.yml)

This is a language server implementing [Language Server Protocol](https://github.com/Microsoft/language-server-protocol) for the [Haxe](http://haxe.org/) language.

The goal of this project is to encapsulate haxe's completion API with all its quirks behind a solid and easy-to-use protocol that can be used by any editor/IDE.

Used by the [Visual Studio Code Haxe Extension](https://github.com/vshaxe/vshaxe). It has also successfully been used in Neovim and Sublime Text[[1]](https://github.com/vshaxe/vshaxe/issues/171)[[2]](https://github.com/vshaxe/vshaxe/issues/328), but no official extensions exist at this time.

Note that any issues should be reported to [vshaxe](https://github.com/vshaxe/vshaxe) directly (this is also the reason why the issue tracker is disabled). Pull requests are welcome however!

**IMPORTANT**: This requires Haxe 3.4.0 or newer due to usage of [`-D display-stdin`](https://github.com/HaxeFoundation/haxe/pull/5120),

[`--wait stdio`](https://github.com/HaxeFoundation/haxe/pull/5188) and tons of other fixes and additions related to IDE support.

### Building From Source

The easiest way to work on the language server is probably to build it as part of the vshaxe VSCode extension as instructed [here](https://github.com/vshaxe/vshaxe/wiki/Installation#from-source) (even if you ultimately want to use it outside of VSCode), which allows for easy debugging.

However, you can also build it as a standalone project like so:

```

git clone https://github.com/vshaxe/haxe-language-server

cd haxe-language-server

npm ci

npx lix run vshaxe-build -t language-server

```

This creates a `bin/server.js` that can be started with `node server.js`.

### Usage with (Neo)vim

There's a large amount of language client plugins for (Neo)vim, but the best choice currently seems to be [coc.nvim](https://github.com/neoclide/coc.nvim). A `coc-settings.json` that is known to work with haxe-language-server looks like this:

```haxe

{

    "languageserver": {

        "haxe": {

            "command": "node",

            "args": [""],

            "filetypes": ["haxe"],

            "trace.server": "verbose",

            "initializationOptions": {

                "displayArguments": ["build.hxml"]

            },

            "settings": {

                "haxe.executable": "haxe"

            }

        }

    }

}

```

### Usage with Kate

Go to configure Kate (`Ctrl+Shift+,`) » `LSP Client` » `User Server Settings` » Add the following snippet to the JSON config within the `servers` object. Don't forget to change the path to the LSP server.

```json

"haxe": {

    "command": ["node", ""],

    "rootIndicationFileNames": ["*.hx", "*.hxml"],

    "url": "https://github.com/vshaxe/haxe-language-server",

    "initializationOptions": {"displayArguments": ["build.hxml"]},

    "settings": {"haxe": {"buildCompletionCache": true}},

    "highlightingModeRegex": "^Haxe$"

},

```

Click `Apply`, you can then close the window. Use `File` » `Reload` or `F5` to reload the project. Accept when it asks you whether you want to start the LSP server.

Where `` can either be a `server.js` you built from source or simply downloaded as part of the Haxe Visual Studio Code extension (`"//.vscode/extensions/nadako.vshaxe-/bin/server.js"`).
