dsh-paste-code-block
Cherry Studio‑style text/code block pasting for DeepSeek Harness Web
Paste long code or text into the DSH Web composer → it lands as a bordered, collapsible, language‑tagged card instead of a wall of text. Names follow the DSH interface language (中文 / English). On send, the original content is restored as a fenced code block.

Preview — pasted blocks become tidy cards
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
Four steps: copy · paste · tidy · send
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.
Block names follow the UI language
- 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
- Copy any code or multi-line text from anywhere.
- Paste into the DSH input → it collapses into a chip such as
代码块 1 / Code #1.
- Click the chip to open the card: read, edit inline, copy, collapse. Click the chip's (or the card's)
× to delete that block.
- 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.
