For example, many languages have the -following syntax for function calls:</p> -<pre><code class="language-js">func(arg1, arg2, arg3); -</code></pre> -<p>A function call might be parsed by tree-sitter into a tree like the following.</p> -<pre><code class="language-tsq">(call - function: (identifier) ; func - arguments: - (arguments ; (arg1, arg2, arg3) - (identifier) ; arg1 - (identifier) ; arg2 - (identifier))) ; arg3 -</code></pre> -<p>Use <code>:tree-sitter-subtree</code> to view the syntax tree of the primary selection. In -a more intuitive tree format:</p> -<pre><code> ββββββ - βcallβ - βββββββ΄βββββ΄ββββββ - β β -βββββββΌβββββ ββββββΌβββββ -βidentifierβ βargumentsβ -β "func" β ββββββ΄ββββ¬ββββββ΄ββββ -ββββββββββββ β β β - β β β - βββββββββββΌβ ββββββΌββββββ ββΌββββββββββ - βidentifierβ βidentifierβ βidentifierβ - β "arg1" β β "arg2" β β "arg3" β - ββββββββββββ ββββββββββββ ββββββββββββ -</code></pre> -<p>If you have a selection that wraps <code>arg1</code> (see the tree above), and you use -<code>Alt-n</code>, it will select the next sibling in the syntax tree: <code>arg2</code>.</p> -<pre><code class="language-js">// before -func([arg1], arg2, arg3) -// after -func(arg1, [arg2], arg3); -</code></pre> -<p>Similarly, <code>Alt-o</code> will expand the selection to the parent node, in this case, the -arguments node.</p> -<pre><code class="language-js">func[(arg1, arg2, arg3)]; -</code></pre> -<p>There is also some nuanced behavior that prevents you from getting stuck on a -node with no sibling. When using <code>Alt-p</code> with a selection on <code>arg1</code>, the previous -child node will be selected. In the event that <code>arg1</code> does not have a previous -sibling, the selection will move up the syntax tree and select the previous -element. As a result, using <code>Alt-p</code> with a selection on <code>arg1</code> will move the -selection to the "func" <code>identifier</code>.</p> - - </main> - - <nav class="nav-wrapper" aria-label="Page navigation"> - <!-- Mobile navigation buttons --> - <a rel="prev" href="install.html" class="mobile-nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> - <i class="fa fa-angle-left"></i> - </a> - - <a rel="next prefetch" href="keymap.html" class="mobile-nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> - <i class="fa fa-angle-right"></i> - </a> - - <div style="clear: both"></div> - </nav> - </div> - </div> - - <nav class="nav-wide-wrapper" aria-label="Page navigation"> - <a rel="prev" href="install.html" class="nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> - <i class="fa fa-angle-left"></i> - </a> - - <a rel="next prefetch" href="keymap.html" class="nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> - <i class="fa fa-angle-right"></i> - </a> - </nav> - - </div> - - - - - <script> - window.playground_copyable = true; - </script> - - - <script src="elasticlunr.min.js"></script> - <script src="mark.min.js"></script> - <script src="searcher.js"></script> - - <script src="clipboard.min.js"></script> - <script src="highlight.js"></script> - <script src="book.js"></script> - - <!-- Custom JS scripts --> - - - </div> - </body> -</html> |
