From a46d13f1896779e22e4188dee41132b8a3df004e Mon Sep 17 00:00:00 2001 From: thePR0M3TH3AN <53631862+PR0M3TH3AN@users.noreply.github.com> Date: Wed, 3 Jun 2026 18:08:42 -0400 Subject: [PATCH] book(I1): CodeMirror markdown editor in chapter pane MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the plain textarea with a CodeMirror 5 instance configured for markdown — syntax highlighting, line wrapping, smart Enter for list continuation. Library: - Vendored CodeMirror 5.65.16 as three files in src/vendor (core, markdown mode, CSS). ~188 KB total. Lazy-loaded through loadCodeMirrorOnce() so the cost is only paid when a chapter opens. Wiring: - openBookChapter kicks off _upgradeChapterEditorToCodeMirror after the existing sync runs. The upgrade swaps the textarea for a CodeMirror instance bound to its DOM node and stores the editor handle on ta._cmEditor. - syncBookChapterEditor pushes value changes through the CM editor when present (only if value differs AND the editor doesn't have focus — preserves the user's caret + IME composition). - Editor change → updateBookChapterMarkdown, which already debounces history + repaints the markdown preview + page-count readout. - Enter on a list line auto-continues the bullet (- / * / +) or numbered marker (1. → 2.); pressing Enter on an empty list item breaks out of the list. - Falls back gracefully to the plain textarea if the CodeMirror download fails (offline / blocked CDN re-host). CSS: - Forces .bookChapterEditorBody .CodeMirror to fill its grid cell (CodeMirror's default is 300 px); matches the surrounding monospace font + line-height so the pre/post-upgrade UX is visually consistent.
