- `@outdent` (default scope `all`):
|
||||
Decrease the indent level by 1. The same rules as for `@indent` apply.
|
||||
|
||||
- `@extend-indented`:
|
||||
- `@extend`:
|
||||
Extend the range of this node to the end of the line and to lines that
|
||||
are indented more than the line that this node starts on. This is useful
|
||||
for languages like Python, where for the purpose of indentation some nodes
|
||||
(like functions or classes) should also contain indented lines that follow them.
|
||||
|
||||
- `@stop-extend`:
|
||||
- `@extend.prevent-once`:
|
||||
Prevents the first extension of an ancestor of this node. For example, in Python
|
||||
a return expression always ends the block that it is in. Note that this only stops the
|
||||
extension of the next `@extend-indented` capture. If multiple ancestors are captured,
|
||||
extension of the next `@extend` capture. If multiple ancestors are captured,
|
||||
only the extension of the innermost one is prevented. All other ancestors are unaffected
|
||||
(regardless of whether the innermost ancestor would actually have been extended).
