# Homescript Language Support for CodeMirror
22

3-
This is an example repository containing a minimal [CodeMirror](https://codemirror.net/6/) language support package. The idea is to clone it, rename it, and edit it to create support for a new language.
3+
This package implements [Homescript](https://github.com/smarthome-go/homescript)
4+
language support for the [CodeMirror](https://codemirror.net/6/) code editor.

Things you'll need to do (see the [language support example](https://codemirror.net/6/examples/lang-package/) for a more detailed tutorial):
6-
7-
* `git grep EXAMPLE` and replace all instances with your language name.
8-
9-
* Rewrite the grammar in `src/syntax.grammar` to cover your language. See the [Lezer system guide](https://lezer.codemirror.net/docs/guide/#writing-a-grammar) for information on this file format.
10-
11-
* Adjust the metadata in `src/index.ts` to work with your new grammar.
12-
13-
* Adjust the grammar tests in `test/cases.txt`.
14-
15-
* Build (`npm run prepare`) and test (`npm test`).
16-
17-
* Rewrite this readme file.
18-
19-
* Optionally add a license.
20-
21-
* Publish. Put your package on npm under a name like `codemirror-lang-EXAMPLE`.
