View git diff in Vim tabs.

• gitdiffall function for zsh (requires ruby for running gitdiffall.rb).
• GitDiff, GitDiffInfo, GitDiffOff commands for Vim.

Install like general Vim plugins.

• With zcomet

  zcomet trigger gitdiffall bootleq/vim-gitdiffall bin

• or zplug

  zplug "bootleq/vim-gitdiffall", use:"bin/*.zsh"

• or Manual install

  1. Execute install.zsh (will ask you for copying scripts to path).
  2. Source path/to/gitdiffall.zsh in your .zshrc.

  if [ -e ~/some_dir/gitdiffall.zsh ]; then
    source ~/some_dir/gitdiffall.zsh
  fi

In zsh, use gitdiffall to open git diff in Vim tabs, examples:

• gitdiffall diff current unstaged/staged changes, like git diff.
• gitdiffall --cached diff staged changes with HEAD.
• gitdiffall dae86e see all changes since commit "dae86e".
• gitdiffall HEAD..HEAD~2 works like git diff HEAD..HEAD~2.

For convenience, some special notations are available:

• gitdiffall @dae86e expands to dae86e^..dae86e,
  this is a shortcut for checking changes at specific commit.
  Examples: @@~2 (HEAD~2), @stash@{0} (stashed entry), @master (last commit at master branch).

• gitdiffall 1 is similar to @<rev>, where <rev> is the 1st previous commit from HEAD.
  You can increase the digit for older commits.

• gitdiffall j and gitdiffall k shortcut to next/previous commit from last evaluated gitdiffall <n>.
  (this uses environment variable $_GITDIFFALL_LAST_SHORTCUT to remember last eval)

During merge conflicts, gitdiffall will open a 3-way diff in Vim.

gitdiffall.rb takes configure file from one of the following:

• $XDG_CONFIG_HOME/gitdiffall/config.rb
• $XDG_CONFIG_HOME/gitdiffall-config.rb
• ~/gitdiffall/config.rb
• ~/gitdiffall-config.rb
• {dir_contains_gitdiffall.rb}/gitdiffall/config.rb
• {dir_contains_gitdiffall.rb}/gitdiffall-config.rb

Supported config items:

• editor_cmd (default: respect $EDITOR, or "vim")
  Command to execute Vim.
• max_files (default: 14)
  Wait for confirmation before open such many files.
• min_hash_abbr (default: 5)
  When performing gitdiffall <n>, <n> must have this many digits to indicate a hash, otherwise it's a number.
• ignore_pattern (default: /\.(png|jpg)\Z/i)
  Files match this pattern will not be sent to Vim.

Example config.rb:

CONFIG = {
  :editor_cmd     => "vim -u /some/other/vimrc",
  :max_files      => 14,
  :min_hash_abbr  => 5,
  :ignore_pattern => /(\.(png|jpg)|-compressed\.js)\Z/i
}

In tmux copy mode, select some commit hash and press > to do gitdiffall in new tmux window, see tmux-in.rb gist.

bind -t vi-copy > copy-pipe "~/.tmux-in.rb gitdiffall"
