windows - 是否可以使用winmerge从cygwin查看git diff？

我喜欢在cygwin上使用git，但是我唯一的缺点是当我想git difftool时我无法使用任何有用的东西。多数时候git diff对我来说都很好，但是有时候我想使用Winmerge通过git difftool查看这些差异，是否可以通过某种方式进行设置？

最佳答案

对于cygwin，可以将SO问题“How can I configure Mercurial to use WinMerge for merges, under cygwin?”应用于git(将以下winmerge脚本与旧问题“use Winmerge inside of Git to file diff”结合使用时)

#!/bin/sh
"/cygdrive/c/Program Files/WinMerge/WinMergeU.EXE" /e /ub /dl other /dr local `cygpath -aw $1` `cygpath -aw $2` `cygpath -aw $3`

过程

您在本文“Git + WinMerge + Cygwin”中有更多详细信息(来自Thiru Thirunavukarasu):
(但我仍然建议您从上面推荐WinMergeU.exe选项)

  [diff]
    tool = winmerge
  [difftool "winmerge"]
    cmd = git-difftool-winmerge-wrapper.sh \"$LOCAL\" \"$REMOTE\"
  [difftool]
    prompt = false

  #!/bin/sh
  echo "Launching WinMergeU.exe \"$(cygpath -aw "$1")\" \"$(cygpath -aw "$2")\""
  if [ -f "$1" -a -f "$2" ]
  then
    "C:/Program Files (x86)/WinMerge/WinMergeU.exe" -e -u -wl -dl "Base" -dr "Mine" "$(cygpath -aw "$1")" "$(cygpath -aw "$2")"
  else
    echo "skipping as one file doesn't exist"
  fi

(再次，使用这些WinMerge选项进行一些测试)

剧本

如果要使用“所有WinMerge”(包括diff和merge git函数)，则可以从gist page to follow获得这个ecerulm (Ruben Laguna):
