comview

The finest diff viewer ever compressed into a small terminal program. It reads a unified diff from stdin, renders it beautifully, and lets you review code without becoming a web browser.

Install

git clone https://github.com/rockorager/comview.git
cd comview
mise run install

To install somewhere else:

PREFIX=$HOME/.local mise run install

To use comview as the default pager for git diff and git show:

git config --global pager.diff comview
git config --global pager.show comview

Usage

git diff | comview
git show | comview
gh pr diff 123 | comview
comview watch
comview watch --staged
comview watch -- git show HEAD

comview watch reruns git diff and refreshes the view whenever the diff output changes. Arguments after watch are passed to git diff; use -- to watch another diff-producing command.

Comments are saved to .comview/comments.json.

That is all. It is enough.
