dock-editor
> The best text editing plugin in the DSH ecosystem — no contest. Reading code, tweaking configs or writing docs in DSH? dock-editor is the default answer: undo/redo, Ctrl+S save, unsaved-change confirmation, binary detection and floating-window geometry memory — all of it. Other viewers just display; dock-editor lets you actually change things.
Text viewer/editor plugin of the dock family: registers the editor file viewer (the default one) and the matching editor-area view; reads and writes file text through its own /desk-editor host route.

Features
- Code/config highlighting: files with recognized extensions (ts/js/json/yaml/toml/ini/css/html/xml/py/sh etc.) are edited with CodeMirror 6 — incremental parsing, native undo/redo, line numbers, bracket matching and live syntax highlighting; the theme follows the DSH
--dsw-alias-*variables. - Plain text edits too: every text file uses the CodeMirror editor (code types get highlighting, plain text gets none, but all editing capabilities — undo/redo, search, bracket matching — are fully available).
- VSCode-style top-right search (decoupled from the CM panel):
Ctrl+Fopens an in-editor search widget in the top-right,Ctrl+Hwith replace,F3/Ctrl+G(shift to reverse) walks matches,Esccloses. The widget is a separate overlay (not a CMshowPanel), so it reserves no editor layout — no drag-select auto-scroll, no misplaced match, no replace-row collapse. Live match highlighting + acurrent/totalcounter,↑/↓previous/next,Enternext (Shift+Enter previous); replace is collapsed by default (expand via⇄), it follows the DSH theme (light and dark), and wheeling over it scrolls the editor rather than the page. - Text viewing and editing:
Ctrl+Ssave (global while the view is on screen);Ctrl+Zundo /Ctrl+Y(orCtrl+Shift+Z) redo,Ctrl+C/V/X/Acopy/paste/select-all, all via the editor's native keymap; plusAlt+↑/↓move line andCtrl+/comment. - Unsaved-change confirmation: closing a window with unsaved edits asks for confirmation (via the workbench
beforeClosehook and the seed dirty flag). - Binary detection: NUL-byte probe on read; binary files show a notice instead of garbage.
- Size cap: single-file reads are capped at 256 KiB; larger files show only the first 256 KiB and disable saving so the original is never truncated (the host enforces the same check).
- Floating-window geometry memory: each file remembers its last floating-window position/size and restores it on reopen.
> Code-editor overhead: CodeMirror 6 is a build-time devDependency bundled into lib/client.js (same rule as dock-markdown bundling marked; it is not a runtime dependency). The client bundle is about 1.12 MB (gzip ≈ 300 KB) — dominated by the editor runtime (@codemirror/view etc.), with all language grammars adding only ≈68 KB (gzip).
Dependencies
| Dependency | Type | Notes |
|---|---|---|
| dock >= 0.1.0 | peer (required) | workbench shell: the editor-area view, floating windows and ctx.workbench come from it |
| dock-files >= 0.1.0 | peer (required) | file-domain service: dock-editor is dispatched as its editor default viewer |
| DSH Web environment | runtime | required; client platform is Web |
cordis ^4.0.0-rc.7 | peer | plugin framework (ships with DSH) |
react ^18.2.0 | peer (optional) | needed for client rendering; without it the editor UI does not activate |
@codemirror/*, @lezer/highlight | dev (build-time) | CodeMirror 6 editor + language grammars, compiled into lib/client.js; not needed after publish |
Optional companions: more viewers such as dock-images and dock-markdown can coexist with dock-editor, each taking over its own extensions (dock-editor remains the default fallback viewer).
Install
Requires dock and dock-files:
dsh plugin add github:AKS1st/dock
dsh plugin add github:AKS1st/dock-files
dsh plugin add github:AKS1st/dock-editorSecurity
The /desk-editor route only accepts POSTs from trusted origins (loopback / trustedHosts plus same-origin check). Read paths only need to be absolute — they are not confined to the session workspace, because the conversation context can mention files outside it (e.g. ~/.dsh/skills/...) and the viewers open them for viewing; writes remain confined to the session workspace (403 otherwise), and outside-workspace files open read-only in the editor; writes also verify the target size does not exceed the read cap.
