Release v0.5.12 · Epistates/treemd

[0.5.12] - 2026-06-06

Toggle mouse capture for text selection - New M shortcut and :toggle mouse capture palette command release the mouse so the terminal's native click-drag selection works for copying arbitrary text; toggle back to restore scroll-wheel navigation. The README also documents the Shift+drag bypass supported by most terminals
Toggle heading markers in outline - New outline_heading_markers config option, # keyboard shortcut, and :toggle heading markers palette command to show/hide #/##/### level prefixes in the outline sidebar (default: true) (#57) — thanks to @alisaifee

Table copy keys did nothing useful - In interactive table mode y/Y/r had been silently rebound to generic copy/raw-source actions during the action-dispatch refactor, so cell, row, and copy-as-markdown copy were inoperative. Restored via dedicated CopyTableCell/CopyTableRow/CopyTableMarkdown actions wired to the existing handlers, with a regression test
Inline backticks render as plain text - Inline code in table cells/headers, headings, and blockquotes now renders as styled inline code via format_inline_markdown() instead of literal backticks (#51, #53). Resolves the known issue carried in 0.5.11; requires turbovault-parser 1.5.0
Navigation to duplicate headings - Selecting an outline entry whose text appears multiple times always jumped to the first occurrence. HeadingNode/OutlineItem now carry a position index, and all content-extraction, selection-restore, and rendering paths resolve by index. extract_section(text) is preserved for the CLI --section flag, delegating to a new extract_section_at_index() (#56) — thanks to @alisaifee
snake_case corruption in subscript rendering - Terms like i_am_a_snake were mangled because _x was always treated as a LaTeX subscript. Subscript conversion now applies to _{x} unconditionally and to bare _x only when not mid-identifier (#58) — thanks to @alisaifee
Mermaid image sizing and scrolling - Mermaid diagrams now expand to fit terminal width and scroll correctly (#53)

Trimmed image format dependencies - ratatui-image 10 → 11 (dropped image-defaults) and image now opts into only the needed decoders (png, jpeg, gif, webp, bmp, ico, tiff), substantially shrinking the dependency tree
Upgraded parser dependencies - turbovault-parser 1.4.1 → 1.5.0 and turbovault-core 1.4.1 → 1.5.0, plus transitive refreshes
Removed outline auto-hide - Dropped the logic that auto-hid the outline when a directory contained few files; outline visibility is now driven solely by user toggle/config
Hardened rendering and TTY handling - Tightened audit findings surfaced during PR #53 review across the CLI, table, and TUI rendering paths

fix: inline backtick rendering in tables, headings, blockquotes and mermaid sizing by @esumerfd in #53
fix(tui): disambiguate navigation to duplicate headings from outline by @alisaifee in #56
fix: prevent snake_case corruption by @alisaifee in #58
feat(tui): add toggle for heading markers in outline sidebar by @alisaifee in #57
