如何在 SVN 中查看文件的所有历史更改 [英] How can I view all historical changes to a file in SVN

问题描述

我知道我可以 svn diff -r a:b repo 查看两个指定修订版之间的更改.我想要的是更改文件的每个修订版的差异.有这样的命令吗?

I know that I can svn diff -r a:b repo to view the changes between the two specified revisions. What I'd like is a diff for every revision that changed the file. Is such a command available?

推荐答案

没有内置命令，所以我通常只做这样的事情:

There's no built-in command for it, so I usually just do something like this:

#!/bin/bash

# history_of_file
#
# Outputs the full history of a given file as a sequence of
# logentry/diff pairs.  The first revision of the file is emitted as
# full text since there's not previous version to compare it to.

function history_of_file() {
    url=$1 # current url of file
    svn log -q $url | grep -E -e "^r[[:digit:]]+" -o | cut -c2- | sort -n | {

#       first revision as full text
        echo
        read r
        svn log -r$r $url@HEAD
        svn cat -r$r $url@HEAD
        echo

#       remaining revisions as differences to previous revision
        while read r
        do
            echo
            svn log -r$r $url@HEAD
            svn diff -c$r $url@HEAD
            echo
        done
    }
}

然后，您可以使用以下命令调用它:

Then, you can call it with:

history_of_file $1
