是否可以将Git配置为使用我配置的difftool git add --patch
?
我想通过我自己的difftool选择要添加到索引的更改。
答案 0 :(得分:10)
不,不幸的是。
我想我可以看到工作--Git根据当前索引中的内容生成一个临时文件,将其与当前工作树版本的副本一起交给difftool(以防止您进行进一步的更改),让您使用difftool将一些更改移动到索引版本,然后一旦您保存并退出,将分析该修改后的索引版本中的任何内容。请注意,这将需要difftool也是一个编辑器,并不是所有有效的difftools;其中一些仅用于查看差异。另请注意,这基本上绕过了git add -p
的所有。你不会有任何正常的界面来在帅哥之间移动,分裂帅哥等等。 difftool将完全负责所有这些。
如果你的difftool功能齐全,可以做到这一点,那么我想你可以编写一个脚本来完成它。大纲,没有任何错误保护,处理特殊情况(二进制文件?),并且完全未经测试:
#!/bin/bash
tmpdir=$(mktemp -d)
git diff --name-only |
while read file; do
cp "$file" $tmpdir
# this has your changes in it
work_tree_version="$tmpdir/$file"
# this has the pristine version
index_version=$(git checkout-index --temp "$file")
# and now you bring changes from the work tree version into the index version,
# within the difftool, and save the index version and quit when done
my_difftool "$work_tree_version" "$index_version"
# swap files around to run git add
mv "$file" "$work_tree_version"
mv "$index_version" "$file"
git add "$file"
mv "$work_tree_version" "$file"
# you could also do this by calculating the diff and applying it directly to the index
# git diff --no-index -- "$file" "$original_index_version" | git apply --cached
rm -r $tmpdir
可能有很多方法可以改善这种状况;抱歉,我现在没有时间小心谨慎。

此处为my script,为您执行2个文件合并打开kdiff3
。如果您不喜欢kdiff3
,请为MERGETOOL
和MERGECMD
提供您自己的值(但您不会喜欢kdiff3
)。
为避免出现意外,此脚本会尝试模仿git add -p
至参数和错误代码。 (它处理文件和目录列表。)
另外,它可以正确处理各种角落案例,包括:
Ctrl+C
使用示例:
$ ## With kdiff3 (default):
$ add-with-mergetool myfile1.txt
$ add-with-mergetool some-directory
$ ## ...or with custom mergetool:
$ export MERGETOOL='opendiff'
$ export MERGECMD='$MERGETOOL $LOCAL $REMOTE -merge $MERGED'
$ add-with-mergetool some-directory/*.py
#!/bin/bash
#
# add-with-mergetool
# Author: Stuart Berg (http://github.com/stuarteberg)
#
# This little script is like 'git add --patch', except that
# it launches a merge-tool to perform the merge.
# TODO: For now, this script hard-codes MERGETOOL and MERGECMD for kdiff3.
# Modify those variables for your own tool if you wish.
# In the future, it would be nice if we could somehow read
# MERGETOOL and MERGECMD from the user's git-config.
# Configure for kdiff3
# (and hide warnings on about modalSession, from kdiff3 on OSX)
MERGETOOL=${MERGETOOL-kdiff3}
MERGECMD=${MERGECMD-'"${MERGETOOL}" "${LOCAL}" "${REMOTE}" -o "${MERGED}"'\
2>&1 | grep -iv modalSession}
main() {
check_for_errors "$@"
process_all "$@"
}
check_for_errors() {
which "${MERGETOOL}" > /dev/null
if [[ $? == 1 ]]; then
echo "Error: Can't find mergetool: '${MERGETOOL}'" 1>&2
exit 1

if [[ "$1" == "-h" ]]; then
echo "Usage: $(basename $0) [<pathspec>...]" 1>&2
exit 0
fi
# Exit early if we're not in a git repo
git status > /dev/null || exit $?
}
process_all() {
repo_toplevel=$(git rev-parse --show-toplevel)
# If no args given, add everything (like 'git add -p')
if [[ $# == 0 ]]; then

fi
# For each given file/directory...
args=( "$@" )
for arg in "${args[@]}"
do
# Find the modified file(s)
changed_files=( $(git diff --name-only -- "$arg") )

set -e
trap "echo && exit 130" INT # Ctrl+C should trigger abnormal exit
# Execute 2-file merge
echo "Launching ${MERGETOOL} for '$f'."
LOCAL="$f.from_index"

如果vimdiff是.gitconfig中的difftool:
[diff]
tool = vimdiff
您也可以站在文件屏幕上执行以下命令:
:!git add %

我喜欢Cascabel和Stuart的答案,因为它们显示了如何编写完成所需任务的封面的脚本。他们使用git add
代替了问题所陈述的git add --patch
,但仍然本着问题的精神。另一种选择是使用git add --edit
,它的优点是根本不需要修改工作树。从逻辑上来说,我的答案是对Stuart脚本的一个小改动。
我在git add --patch
上遇到的问题是,它本质上是交互式的,因此很难覆盖脚本。 Stuart的方法是使用差异工具来确定所需的索引完整内容,然后使用git add
来实现。我的方法的不同之处在于,在调用git add
之前和之后,我没有修改工作树,而是获取了所需的完整内容,并将其变成可应用于索引的补丁。然后可以使用EDITOR="mv \"$PATCH\"" git add --edit
来做到这一点。这样可以避免修改工作树。
要使用此方法,请从Stuart的脚本开始,并用以下内容替换patch_file_and_add
的定义:
patch_file_and_add() {
f="$1"
base=$(basename "$f")
dir=$(mktemp -d)
mkdir "$dir/working"
mkdir "$dir/index"
mkdir "$dir/merged"
LOCAL="$dir/working/$base"
REMOTE="$dir/index/$base"
MERGED="$dir/merged/$base"
PATCH1="$dir/head.patch"
PATCH="$dir/full.patch"
git show :"$f" > "$REMOTE" # Copy from the index
(
set -e
trap "echo && exit 130" INT # Ctrl+C should trigger abnormal exit
# Execute 2-file merge
echo "Launching ${MERGETOOL} for '$f'."
cp "$f" "$LOCAL"
eval "${MERGECMD}"
if [[ -e "$MERGED" ]]; then
git diff -- "$f" > "$PATCH1" 2> /dev/null
git diff --staged -- "$f" >> "$PATCH1" 2> /dev/null
# We need both of the above in case one is empty.
head -4 "$PATCH1" > "$PATCH"
diff --unified=7 "$REMOTE" "$MERGED" | tail -n +3 >> "$PATCH"
# Now we have the patch we want to apply to the index.
EDITOR="mv \"$PATCH\"" git add -e -- "$f"
fi
rm -rf "$dir"
)
status=$?
if [ $status == 130 ]; then
echo "User interrupted." 1>&2
exit $status
elif [ $status != 0 ]; then
echo "Error: Interactive add-patch stopped early!" 1>&2
exit $status
fi
}
严格来说,可以将LOCAL
设置为$f
,而不必使用mv
将其放在其他位置。但是我似乎记得,一些第三方差异程序允许隐藏路径的公共初始部分,因此这种方法可以利用该功能。
感谢Cascabel和Stuart的出色回答,以及HaxElit的出色问题。

不幸的是没有。
目前我所知道的唯一用户界面是git-gui的一部分,当被调用为
时git gui citool
另一个UI是作为
调用时的交互式控制台UIgit add -i
git difftool允许一些不同的工具选项,但不允许添加接口。
