|

<p>Textobjects that are language specific (<a href="../usage.html#textobjects">like functions, classes, etc</a>)
|
||||
require an accompanying tree-sitter grammar and a <code>textobjects.scm</code> query file
|
||||
to work properly. Tree-sitter allows us to query the source code syntax tree
|
||||
and capture specific parts of it. The queries are written in a lisp dialect.
|
||||
More information on how to write queries can be found in the <a href="tree-sitter-queries">official tree-sitter
|
||||
documentation</a>.</p>
|
||||
<p>Query files should be placed in <code>runtime/queries/{language}/textobjects.scm</code>
|
||||
when contributing. Note that to test the query files locally you should put
|
||||
them under your local runtime directory (<code>~/.config/helix/runtime</code> on Linux
|
||||
for example).</p>
|
||||
<p>The following <a href="https://tree-sitter.github.io/tree-sitter/using-parsers#capturing-nodes">captures</a> are recognized:</p>
|
||||
<table><thead><tr><th>Capture Name</th></tr></thead><tbody>
