Docview

Markdown doc viewer side panel for the OpenCode TUI, with line numbers and GitHub-style range copying.

Requires OpenCode 2.x.

Install

Add it to ~/.config/opencode/cli.json and restart the TUI:

{ "plugins": ["opencode-docview"] }

Use

• /doc path/to/file.md or /doc @file opens a doc; /doc alone opens a picker.
• Click or drag the line numbers to copy a range like #L3-L8. Shift-click extends it.
• Frontmatter is dimmed and unnumbered, so L1 is the first line after it.
• The panel reloads when the file changes.

Key	Action
j / k, g / G	Scroll, top / bottom
s	Rendered / source view
y / esc	Copy / clear selection
o / r	Open another doc / reload
f / q	Fullscreen / close

<leader> left and <leader> right move focus between the prompt and the panel.
