dsh-paste-code-block

Why

Copying a 200‑line stack trace, an API response, or a long log into a chat input turns the composer into an unreadable blob. This plugin folds any qualifying paste into a chip (built on DSH's own hidden‑reference mechanism, the same one file uploads use) plus an editing detail card — the draft stays clean, and the content stays fully editable and restorable.

Features

• 🧩 Auto block detection — pasted text with ``` fences, newlines, heavy indentation, or length ≥ 96 becomes a card; ordinary short prose pastes through untouched.
• 🏷️ Language tags — auto-detects Python / JS / JSON / YAML / SQL / bash / HTML·XML / C++ / Go / Ruby (incl. shebangs); plain-text blocks are tagged text.
• ✏️ In-card editing — edit the content right in the detail card; the edited text is exactly what gets sent. Plus copy, collapse/expand, and hide.
• 🈯 Localized names — chips are named in the current DSH language: 代码块 1 / Code #1, 文本块 N / Text #N. A leading glyph and tint tells the two apart at a glance — </> blue for code, Aa gray for text. Switching Settings → Language live-retitles every chip.
• × One-click remove — every chip carries its own × delete button (the detail card has one too); a removed number is recycled immediately.
• 📤 Fenced restore on send — each card expands back into a ```lang … ``` block when you send; a failed send automatically refills the input.
• 🔢 Smart numbering — code and text count apart; the smallest free number is always reused.
• 📱 Every surface — pure client plugin; works on desktop & mobile web, follows light/dark themes.

How it works

Localization

Chip labels, tooltips, line counts, and the send-time error notice all render through the official DSH locale service: the plugin registers a paste-code-block dictionary namespace with complete zh / en key sets, and its composer dock declares that namespace, so everything re-renders on every language switch.

• New pastes are named in whatever language is active at paste time.
• Existing chips are re-titled live when you flip 设置 → 语言 / Settings → Language — no reload needed.
• Clicks and deletes match chips across languages: a 代码块 2 chip still resolves to its block after switching to English (where it now reads Code #2), and vice versa.

Install

Requires DSH 0.1.x (developer preview — APIs may change). Published on npm — install by name:

dsh plugin --profile web add dsh-paste-code-block

Or from this repository / a local checkout:

dsh plugin --profile web add github:cjm-m/dsh-paste-code-block   # from GitHub
dsh plugin --profile web add file:/path/to/dsh-paste-code-block  # from a local folder

Restart dsh web after installing.

Usage

1. Copy any code or multi-line text from anywhere.
2. Paste into the DSH input → it collapses into a chip such as 代码块 1 / Code #1.
3. Click the chip to open the card: read, edit inline, copy, collapse. Click the chip's (or the card's) × to delete that block.
4. Send — the full original text goes out as a proper fenced code block.

Detection threshold: contains a newline / ≥ 2 lines / length ≥ 96 / indented & brace-dense / fenced — any one turns the paste into a block.

Notes & boundaries

• Blocks are appended at the end of the draft (reusing DSH's hidden-reference semantics), which keeps cursor/undo stable.
• Plain-text blocks are sent wrapped in ```text ``` so they never smear into one line.
• Removing a chip any other way (e.g. Backspace) also frees its number — plugin state is reconciled against the editor continuously.
• Deleting one block never touches the others, and removal is an ordinary editor edit — Ctrl+Z brings it back.
• Creating a block leaves no stray space: DSH appends a separating space after a freshly inserted chip, and the plugin removes exactly that one character, so text typed after a block does not start with a space and pasting several blocks never piles spaces into the message. Spaces you typed yourself are never touched by pasting or deleting.
