Git diff side by side

Alternative 1

Use icdiff, as instructed on https://blog.scottnonnenberg.com/better-git-configuration/

1. install icdiff (from https://github.com/jeffkaufman/icdiff but ubuntu also has a package)

2. add to your ~/.gitconfig:

   [diff] tool = icdiff [difftool] prompt = false [difftool "icdiff"] cmd = /usr/local/bin/icdiff --line-numbers $LOCAL $REMOTE

3. use git difftool ... to use instead of git diff, e.g. git difftool master to compare current branch and master.

How to get a side by side diff with git diff in the terminal.

Requirements:

• sdiff (from diffutils)
• colordiff

Place the following in your PATH (eg ~/bin/diffy):

#!/bin/sh
echo
echo Comparing: "$1 between $3 and $6"
echo
if stty >/dev/null 2>&1; then
  pager=${PAGER:-less -r}
else
  pager=cat
fi
C=$(stty size | cut -d' ' -f2)
D=$(expr $C / 2)
sdiff -W -w $C "$2" "$5" | colordiff | grep -E "^.{$D} *[|<>] *" -A 10 -B 10 -n | $pager

Then set the environment variable GIT_EXTERNAL_DIFF to point to it.
