我几乎设法将整个git log输出转换为有效JSON格式，现在唯一缺少的是去掉JSON数组末尾的尾随逗号（见下面的输出）。

由于awk到目前为止我已经使用它来使其正常工作，因此我更愿意继续使用它，除非我可以使用其他东西获得完全相同的输出。我愿意接受任何建议！

该脚本放置在git存储库的根目录中，并从终端运行，如：

./gitlog.sh

（考虑到您已经 cd'ed 到存储库的根目录）

如您所见，这里的问题是该行为循环中的每一行（包括最后一行）输出一个逗号（通过我命名print t t cr e;的预定义变量）。:(awke

我尝试过的：

我替换print t t cr e;为：

if (getline == 0) { print t t cr; } else { print t t cr e; }

getline当它到达最后一行时应该返回0，但这不是一个可靠的解决方案：它停在我的 25 行输出（25 次提交）的第 13 行。我还使用官方 git 存储库 ( https://github.com/git/git/commits/master ) 测试了这种方法。最后一次提交后，我仍然得到尾随逗号。

由于脚本中的某些缺陷，可能getline无法获得真实的行数。但两者都NR返回count准确的行数。

任何帮助是极大的赞赏！

您可以尝试的一种解决方案是在下一行的开头而不是在上一行的末尾添加逗号，并使用该printf函数来处理换行符。

在awk脚本中，我检查 line 是否不是第一个并添加逗号：

BEGIN {
    print cl;
    print t q "commits" q c bl;
}
{
    count++;
    #--------------------
    if ( count > 1 ) {
      printf "%s\n", e
    }
    #--------------------
    ...
} END {
    ...
}' > gitlog.json

在最后一行的打印中，我printf用来避免或添加额外的换行符：

...
printf "%s%s%s", t, t, cr;
} END {
    printf "\n%s%s\n", t, br;
    print cr;
}' > gitlog.json

我已经对其进行了测试，并且似乎可以正常工作。我希望它对你有用。
