自给定提交以来git中的作者列表 [英] List of authors in git since a given commit

问题描述

我想要一种列出所有git作者的方法

I want a way to list all git authors that

1. 仅自给定提交以来.
2. 是独一无二的.

这两个很容易，我在网上看到了一些解决方案，大多数使用git log --format.但是我发现没有一个符合其他要求:

These two are easy, and I've seen some solutions to this online, most using git log --format. But none that I saw fits the additional requirements:

1. 按提交日期排序.因此，如果约翰·史密斯(John Smith)在亚伦·梅勒(Aaron Meurer)之前犯下过罪行，那么他的名字应该出现在我的名字之前(我是亚伦·梅勒(Aaron Meurer).
2. 尊重.mailmap.据我所知，只有git shortlog可以做到这一点，并且它提供了很多我不想要的东西.但是也许我错了.或者也许你们当中那些比我更方便使用sed和朋友的人.

1. Is ordered by commit date. So if John Smith committed before Aaron Meurer, his name should appear before mine (I'm Aaron Meurer).
2. Respects .mailmap. As far as I can tell, only git shortlog does this, and it gives a bunch of extra stuff that I don't want. But maybe I'm wrong. Or maybe those of you who are more handy with sed and friends than I am would just use that.

(顺便说一句，如何让Markdown not 不重新开始编号?)

(by the way, how do I make Markdown not restart the numbering?)

我还想一种按姓氏排序的方法，但这相对容易.

I also want a way to order it by last name, but this is relatively easy.

推荐答案

以下格式说明符将解决您的第二个问题:

The following format specifiers will solve your second concern:

％aN:作者姓名(尊重.mailmap)
％aE:作者电子邮件(使用.mailmap)
％cN:提交者名称(使用.mailmap)
％cE:提交者电子邮件(尊重.mailmap)

%aN: author name (respecting .mailmap)
%aE: author email (respecting .mailmap)
%cN: committer name (respecting .mailmap)
%cE: committer email (respecting .mailmap)

因此，除去重复的作者部分，您需要类似

So discounting the duplicate author part, you want something like

git log <commit>.. --format="%aN <%aE>" --reverse

我怀疑您可以通过基于哈希表的重复数据删除将其通过管道传输，而perl oneliner可能是微不足道的:

I suspect you could pipe it through something that does a hash-table based deduplication, a perl oneliner would be trivial:

git log <commit>.. --format="%aN <%aE>" --reverse | perl -e 'my %dedupe; while (<STDIN>) { print unless $dedupe{$_}++}'
