This package implements the language support infrastructure for the
|
|
[CodeMirror](https://codemirror.net/) code editor.
|
|
|
|
The [project page](https://codemirror.net/) has more information, a
|
|
number of [examples](https://codemirror.net/examples/) and the
|
|
[documentation](https://codemirror.net/docs/).

|
We aim to be an inclusive, welcoming community. To make that explicit,
|
|
we have a [code of
|
|
conduct](http://contributor-covenant.org/version/1/1/0/) that applies
|
|
to communication around the project.
|
|
|
|
## Usage
|
|
|
|
Setting up a language from a [Lezer](https://lezer.codemirror.net)
|
|
parser looks like this:
|
|
|
|
```javascript
|
|
import {parser} from "@lezer/json"
|
|
import {LRLanguage, continuedIndent, indentNodeProp,
|
|
foldNodeProp, foldInside} from "@codemirror/language"
|
|
|
|
export const jsonLanguage = LRLanguage.define({
|
|
name: "json",
|
|
parser: parser.configure({
|
|
props: [
|
|
indentNodeProp.add({
|
|
Object: continuedIndent({except: /^\s*\}/}),
|
|
Array: continuedIndent({except: /^\s*\]/})
|
|
}),
|
|
foldNodeProp.add({
|
|
"Object Array": foldInside
|
|
})
|
|
]
|
|
}),
|
|
languageData: {
|
|
closeBrackets: {brackets: ["[", "{", '"']},
|
|
indentOnInput: /^\s*[\}\]]$/
|
|
}
|
|
})
|
|
```
|
|
|
|
Often, you'll also use this package just to access some specific
|
|
language-related features, such as accessing the editor's syntax
|
|
tree...
|
|
|
|
```javascript
|
|
import {syntaxTree} from "@codemirror/language"
|
|
|
|
const tree = syntaxTree(view)
|
|
```
|
|
|
|
... or computing the appriate indentation at a given point.
|
|
|
|
```javascript
|
|
import {getIndentation} from "@codemirror/language"
|
|
|
|
console.log(getIndentation(view.state, view.state.selection.main.head))
|
|
```
