Code File Embed

Embed the current contents of a vault file as a syntax-highlighted code block, instead of copy-pasting code into a fenced block.

Usage

Point a codefile block at a file. The language is inferred from the extension.

```codefile src/foo.abap
```

Line range (1-based, inclusive):

```codefile src/foo.abap:10-25
```

Single line: :10. The path can also go in the block body (first line) if you prefer. Paths resolve like Obsidian links (relative to the current note, shortest-unique names work).

Features

• Syntax highlighting by extension, reusing Obsidian's own renderer (theme + copy button included).
• Live update: the block re-renders when the target file is saved or renamed.
• Optional clickable header showing the file path.
• Configurable extension → language map and max file size in settings.

Development

npm install
npm run dev    # watch build -> main.js
npm run build  # type-check + production bundle
npm test       # unit tests (parser, langMap)

Copy main.js, manifest.json, and styles.css into <vault>/.obsidian/plugins/codefile/ to try it in a vault.
