From 445aba97620b8856f396669570265f19d890dd10 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 9 Mar 2026 22:01:51 +0000 Subject: [PATCH 1/8] feat(ast-engine): support TAB indentation parsing * Added `get_tab` utility function for parsing tab characters from content. * Refactored `get_indent_at_offset` to handle tabs by returning `is_tab` along with indent offset. * Handled the stripping and insertion of mixed-tabs vs space indent characters properly inside `remove_indent` and `indent_lines_impl`. * Plumbed the `is_tab` boolean down through `formatted_slice` and `indent_lines`. * Updated tests in `indent.rs` to exercise proper TAB character extraction and re-indentation rules.
