README.md

Requirements:

• fzf
• git

Commands:

• git first-child REV: Returns the first child of REV
• git my-last-commit: Returns the last commit of the current user (from the current branch)
• git my-files: Returns a list of files the current user has changed sometime
• git my-diff REV: Returns a diff from HEAD to REV with a filter to my-files
• git my-diff-since-last-commit: The diff from HEAD to my-last-commit with the filter to my-files. This is the diff that is relevant for the user.
• git personal-diff: Same as above, but in fzf.

The personal diff will open fzf with the files that are relevant to the user. In fzf the files diff is previewed.

• enter: Open the diff
• ctrl-f: Toggle view (vertical to horizontal)
• ctrl-u, ctrl-d: Scrol up/down half a page in the preview
• ctrl-n, ctrl-p: Scrol down/up in the file list
• shift-up, shift-down: Scrol up/down in the preview
• ctrl-y: Copy the filename to the clipboard (clip.exe, you might change that)
• ctrl-o: Opens the file in VS Code (you might change that too)
