如何在GIT repo中列出目录以及每个目录条目的最新提交信息？ [英] How to list a directory in a GIT repo together with the latest commit info for each directory entry?

问题描述

我想从GIT存储库中列出一个目录以及每个目录条目的最新提交信息。熟悉Github如何显示目录或viewvc如何在SVN / CVS仓库中显示目录。

目前我这样做：

1. 获取目录 git ls-tree master 的条目并从输出中解析出目录结构。

然后对每个目录条目我这样做： git log -n 1 master - filename 并解析它的提交信息（我指定了一个特殊的格式字符串以使这更容易，但是这不是与我的问题无关）




显然这很慢，因为我必须为每个git调用git文件。有没有更快的方法来做到这一点？也许我可以执行一个命令来获得我需要的所有数据？

解决方案

Oneliner解析 git whatchanged 输出和用最近的提交ID标注的打印树：



  git whatchanged -r  - pretty = oneline | perl -ne'我们的％q; if（/ ^（[0-9a-f] {40}）/）{$ c = $ 1} if（/:.{38}(.*)/）{$ q {$ 1} = $ c除非存在$ q {$ 1}}; END {print map {$ q {$ _} $ _\\\
}（键％q）; }'| sort -k 2 
  

输出示例：

 b32f7f65f19e547712388d2b22ea8d5355702ce2代码/ unfreezemodule /生成文件

Y您可以调整 git whatchanged 参数和/或根据需要过滤输出。




I want to list a directory from a GIT repository together with the latest commit info of each directory entry. Similiar to how Github displays directories or how viewvc displays a directory in a SVN/CVS repo.

Currently I do it like this:

1. Get the directory entries with git ls-tree master and parse the directory structure from the output.

2. Then for each directory entry I do this: git log -n 1 master -- filename and parse the commit info from it (I specify a special format string to make this easier, but this isn't relevant to my problem)

It's pretty obvious that this is very slow because I have to call git for each file. Is there a faster way to do this? Maybe a single command I can execute to get all the data I need at once?

解决方案

Oneliner to parse git whatchanged output and print tree annotated with recent commit ids:

git whatchanged -r --pretty=oneline | perl -ne 'our %q; if (/^([0-9a-f]{40})/) {$c = $1} if (/:.{38}(.*)/) { $q{$1} = $c unless exists $q{$1} }; END { print map {"$q{$_} $_\n"} (keys %q); }'  | sort -k 2

Example output:

b32f7f65f19e547712388d2b22ea8d5355702ce2 code/unfreezemodule/file.c
b32f7f65f19e547712388d2b22ea8d5355702ce2 code/unfreezemodule/Makefile

You can adjust git whatchanged parameters and/or filter the output as you want.
