Features

• 📋 Smart detection — pasted content with ``` fences, newlines, or long indented code becomes a card; ordinary short prose pastes as-is.
• 🏷️ Language tags — auto-detects Python / JS / JSON / YAML / SQL / bash / HTML·XML / C++ / Go / Ruby (incl. shebang). Plain text blocks are tagged text.
• 📂 Collapsible card — collapsed by default showing a one-line preview; click to expand full code (scrollable, up to 260px).
• ✏️ In‑card editing — edit the block content right in the detail card; the send path uses your edited text.
• 📤 Restore on send — each card is restored to a ```lang … ``` fenced block; a failed send auto-fills it back into the input.
• 🔢 Smart numbering — code and text are counted apart; deleting a block frees its number for reuse (smallest-free allocation).
• 📱 All surfaces — pure client plugin; works on PC & mobile Web, adapts to light/dark themes.

Install

Requires DSH 0.1.x (current developer preview — APIs may change).

Published on npm — install directly by name:

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

Alternatively, install from this Git repository or a local folder:

# From GitHub
dsh plugin --profile web add github:cjm-m/dsh-paste-code-block

# From a local checkout
dsh plugin --profile web add file:/path/to/dsh-paste-code-block

Restart dsh web after installing.

Usage

1. Copy a block of code or a multi-line block of text anywhere.
2. Paste it into the DSH input → it becomes a code-block card.
3. Expand / copy / edit / remove as you like; press Enter or send and it's restored as a fenced code block.

Notes & boundaries

• Blocks are appended at the end of the draft (reusing DSH's hidden-reference semantics), keeping cursor/undo stable; ordinary short text is not intercepted.
• Plain-text blocks are wrapped in ```text ``` on send so they don't smear into one line.
• Detection threshold: contains newline / ≥2 lines / length ≥96 / indented or fenced — any one triggers the card.
