# LSP Server for EOLANG
[](https://codecov.io/gh/objectionary/eo-lsp-server)
[](https://hitsofcode.com/view/github/objectionary/eo-lsp-server)
This is the [LSP] server for [EO](https://github.com/objectionary/eo).
It provides semantic highlighting and parsing error checking for `.eo` files
(written in [EOLANG]).
In order to use it, you need to have [Node] and [npm] installed.
## Using with IntelliJ (with LSP4IJ)
[LSP4IJ](https://github.com/redhat-developer/lsp4ij), a free LSP support plugin
for [IntelliJ], provides an [EO LSP server template][lsp4ij-doc]
to automatically install and run the `LSP Server for EOLANG`:
* Install [LSP4IJ](https://plugins.jetbrains.com/plugin/23257-lsp4ij)
into [IntelliJ]
* Open any `*.eo` file, a notification will appear with
`Install LSP Server for EOLANG`
* Click the link, confirm the server creation, then click `OK`
* The server will be installed (via [npm])
Once done, semantic tokens and diagnostics will be available.
## Using with Sublime Text
To use this [LSP] server with [Sublime Text], you'll need to install
the [LSP package] and configure it
in `Settings → Package Settings → LSP → Settings`:
```json
{
"clients": {
"eo-lsp": {
"enabled": true,
"command": ["npx", "-y", "eo-lsp-server@0.2.0", "--stdio"],
"selector": "source.eo"
}
}
}
```
Then, create a syntax definition file [in][packages]
`~/Library/Application Support/Sublime Text/Packages/User/EO.sublime-syntax`:
```yaml
%YAML 1.2
---
name: EO
file_extensions:
- eo
scope: source.eo
contexts:
main:
- match: '^\+[^\n]+$'
scope: meta.eo
- match: '#.*$'
scope: comment.line.eo
- match: '[@^*?]'
scope: keyword.eo
- match: '[\[\]\\>!:\.\)\(]|\+>'
scope: keyword.operator.eo
- match: '"[^"]*"'
scope: string.quoted.double.eo
- match: '\b(\+|-)?\d+(\.\d+(e(\+|-)?\d)?)?\b'
scope: constant.numeric.eo
```
Should work. If it doesn't, [file an issue], we'll help.
## How to Contribute
First, install [Node] modules with:
```bash
npm install
```
Then, build the project:
```bash
make
```
Make changes on a new branch.
You can run an instance of [VS Code] with the extension running by hitting `F5`
in the code editor.
After modifications, test your code with:
```bash
make test
```
