dock-editor

中文

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+F opens an in-editor search widget in the top-right, Ctrl+H with replace, F3/Ctrl+G (shift to reverse) walks matches, Esc closes. The widget is a separate overlay (not a CM showPanel), so it reserves no editor layout — no drag-select auto-scroll, no misplaced match, no replace-row collapse. Live match highlighting + a current/total counter, ↑/↓ previous/next, Enter next (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+S save (global while the view is on screen); Ctrl+Z undo / Ctrl+Y(or Ctrl+Shift+Z) redo, Ctrl+C/V/X/A copy/paste/select-all, all via the editor's native keymap; plus Alt+↑/↓ move line and Ctrl+/ comment.
• Unsaved-change confirmation: closing a window with unsaved edits asks for confirmation (via the workbench beforeClose hook 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

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:

Recommended install from the npm registry:

dsh plugin --profile web add dock-base
dsh plugin --profile web add dock-files
dsh plugin --profile web add dock-editor

Or install from GitHub (alternative):

dsh plugin --profile web add github:AKS1st/dock
dsh plugin --profile web add github:AKS1st/dock-files
dsh plugin --profile web add github:AKS1st/dock-editor

Security

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.
