我正在开发一个预提交 Hook ,它使用 YUI 压缩机来缩小已准备提交的任何 CSS 和 JavaScript 文件。文件缩小后,缩小版本会自动暂存以供提交。我读过,自动将机器生成的文件添加到提交中通常不是一个好主意,但我认为在这种情况下这是可以的。它看起来像这样:
git status
的输出:
# On branch master
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: _site-wide.css
#
# Changes not staged for commit:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# modified: _subpage.css
#
git commit -m“更新站点范围样式”的输出
:
1 CSS file was minified and added to the Git repository
0 JavaScript files were minified and added to the Git repository
[master 41f1815] Updated site-wide styling
2 files changed, 2 insertions(+), 2 deletions(-)
这里发生的是预提交钩子(Hook)使用 YUI Compressor 来缩小 _site-wide.css
,将结果输出到 site-wide.css
(没有前导下划线) )。然后,它暂存 site-wide.css
进行提交。预提交 Hook 跳过了 _subpage.css
,因为尽管它已被修改,但它并未暂存以供提交。
由于磁盘上的 CSS 和 JavaScript 文件可能与准备提交的 CSS 和 JavaScript 文件不同,因此我在缩小文件之前运行 git stash -q --keep-index ,然后之后运行 git stash pop -q 。这个预提交钩子(Hook)在已经有提交的存储库上工作得很好,但是如果我在第一次提交之前将预提交钩子(Hook)放在适当的位置,我会得到这个:
git status
的输出:
# On branch master
#
# Initial commit
#
# Changes to be committed:
# (use "git rm --cached <file>..." to unstage)
#
# new file: _site-wide.css
# new file: _subpage.css
#
git commit -m "Initial commit"的输出
:
fatal: bad revision 'HEAD'
fatal: bad revision 'HEAD'
fatal: Needed a single revision
You do not have the initial commit yet
2 CSS files were minified and added to the Git repository
0 JavaScript files were minified and added to the Git repository
No stash found.
git status
的输出:
# On branch master
#
# Initial commit
#
# Changes to be committed:
# (use "git rm --cached <file>..." to unstage)
#
# new file: _site-wide.css
# new file: _subpage.css
# new file: site-wide.css
# new file: subpage.css
#
我现在将粘贴预提交 Hook 的代码。请记住,为了灵活,我编写了此脚本,以便它可以在任何 CakePHP 项目中运行,而不仅仅是具有 Git 存储库的项目。我还编写了它,以便您可以强制它缩小所有 CSS 和 JavaScript 文件,而不仅仅是那些准备提交的文件。这是通过运行 .git/hooks/pre-commit force 来完成的。这是代码:
#!/bin/bash
css_files_to_ignore=(
#"_do_not_minify.css"
)
js_files_to_ignore=(
#"_do_not_minify.js"
)
if git rev-parse --git-dir > /dev/null 2>&1; then
git_repository=true
base_folder="$(git rev-parse --show-toplevel)/app/webroot"
if [ "$1" == "force" ]; then
process_unstaged_files=true
else
process_unstaged_files=false
fi
else
git_repository=false
base_folder="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)/webroot"
fi
if [ -f /Applications/yuicompressor.jar ]; then
# Mac
yuicompressor_path=/Applications/yuicompressor.jar
else
# Linux
yuicompressor_path=$(command -v yui-compressor)
fi
function process_assets()
{
extension=$1
files_minified=0
for infile in $(echo "$base_folder/$extension/*.$extension")
do
# Only process files.
[[ -f $infile ]] || continue
filename=${infile##*/}
# If the filename starts with an underscore, that means that the file is
# eligible for minification.
[[ ${filename:0:1} == "_" ]] || continue
ignore_this_file=false
files_to_ignore=$extension"_files_to_ignore"
for i in $(eval echo \${$files_to_ignore[@]})
do
if [[ $i == $filename ]]; then
ignore_this_file=true
break
fi
done
if [ $git_repository == true ] && [ $process_unstaged_files == false ] && git diff --quiet --cached $infile; then
# This file is NOT staged for commit.
ignore_this_file=true
fi
if [ $ignore_this_file == false ]; then
minified_file="$base_folder/$extension/${filename:1}"
if [ ! -f "$minified_file" ] || test $infile -nt $minified_file; then
$yuicompressor_command "$infile" -o "$minified_file"
if [ $git_repository == true ] && [ $process_unstaged_files == false ]; then
git add "$minified_file"
fi
((files_minified++))
fi
fi
done
# Output a summary of what was done.
if [ $extension == "css" ]; then
file_type="CSS"
else
file_type="JavaScript"
fi
echo -n "$files_minified $file_type file"
if [ $files_minified -eq 1 ]; then
echo -n " was"
else
echo -n "s were"
fi
echo -n " minified"
if [ $git_repository == true ] && [ $process_unstaged_files == false ]; then
echo " and added to the Git repository"
else
echo
fi
}
if [ -f "$yuicompressor_path" ]; then
if [ ${yuicompressor_path: -4} == ".jar" ]; then
yuicompressor_command="java -jar $yuicompressor_path"
else
yuicompressor_command=$yuicompressor_path
fi
if [ $git_repository == true ] && [ $process_unstaged_files == false ] && ! git diff --quiet --cached; then
# The staging area is what should be processed rather than what is currently
# on disk.
git stash -q --keep-index
stashed=true
else
stashed=false
fi
process_assets css
process_assets js
if [ $stashed == true ]; then
git stash pop -q
fi
else
echo "YUI Compressor was not found. Aborting."
exit 1
fi
我怎样才能做到这一点?任何帮助将不胜感激。
最佳答案
我得出的结论是没有解决方案,因为一些 Git 命令在没有 HEAD 时根本无法工作。另外,经过更多思考后,我认为这无论如何都是一种边缘情况,至少对我来说是这样,因为我的第一次提交通常是一些基本的东西,例如我使用的框架的文件。所以我可以在第一次提交后实现钩子(Hook)。
我感谢哈塞克以及其他阅读本文的人所花费的时间。谢谢!
