Question

我使用以下代码获取上次提交中更改的文件的名称：

git log -1 --stat

现在我想将结果解析为JSON。我知道我可以使用漂亮的格式来解析所有＆＃39; git log＆＃39;将数据转换为JSON（pretty-formats），如下所示：

git log \
--pretty=format:'{%n  "commit": "%H",%n  "author": "%an <%ae>",%n  "date": "%ad",%n  "message": "%f"%n},' \
$@ | \
perl -pe 'BEGIN{print "["}; END{print "]\n"}' | \
perl -pe 's/},]/}]/'

但是有没有办法解析这个JSON，例如更改文件名？

Answer 1

您可以执行以下操作：

function getcommit { \
    git show --pretty="format:"  --name-only $1 | \
    perl -pe's/^\n//g;' | \
    sed 's/\(.*\)/"\1"/g' | \
    perl -0pe 's/\n(?!\Z)/,\n/g'; \
}

export -f getcommit

git log -1 --pretty=format:'{%n  "commit": "%H",%n  "author": "%an <%ae>",%n  "date": "%ad",%n  "message": "%f",%n  "files": [ COMMIT_HASH_%H  ]%n},' | \
perl -pe 'BEGIN{print "["}; END{print "]\n"}' | \
perl -pe 's/},]/}]/;s/COMMIT_HASH_(\w+)/`echo -n "";getcommit $1`/e'

基本上，我在哈希本身之前用固定字符串COMMIT_HASH_替换了提交哈希值，然后将此哈希值替换为git show --pretty="format:" --name-only $COMMIT_HASH的结果。

所有更改的文件都放入json数组＆＃34;文件＆＃34;。这适用于最后的X提交

以下是最后一次提交的示例：

这是一个脚本，它在参数中获取提交索引并返回包含已更改文件的json信息：https://gist.github.com/akinaru/a4ed5d76562e74d77282

Answer 2

代替困难的正则表达式和自定义 Bash 函数，您只需使用 xidel（真正的 JSON 解析器）从 1 个 git-command 创建 JSON 数组。

为了说明，我将从 FFmpeg repo 中获取最新的 3 次提交。

通过在空行上“标记化”来创建每个提交的序列。
对于每次提交，创建一个变量来保存每一行的序列。
（x:lines($cmt) 是 tokenize($cmt,'\r\n?|\n') 的简写）
从对应的每一行返回 JSON 对象，其中文件列表变成了从第 nr.5 行到最后一行的数组。
