From e87e16547a17864b2a0cd574c1aa42d44125bc6c Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 16:35:27 -0300 Subject: Alt-o, Alt-i and the other tree-sitter keys walk the file's syntax tree helix's expand/shrink, previous/next sibling, all siblings, all children and parent-node end/start (Alt-o/up, Alt-i/down, Alt-p/left, Alt-right, Alt-a, Alt-I, Alt-e, Alt-b; Alt-n stays the new terminal) walk a whole-file parse the file keeps (File.node_tree), made on the first such key after an edit and reused until the next, never per key. syntax.walkNodes follows helix's TreeCursor over every node, anonymous ones included, and Alt-i goes back to what Alt-o grew from while the selection still holds it. The harness runs without grammars, so the cases prove the plain-text no-op; a test replays eleven JSON walks whose results were taken from the installed hx.
