如何查看git仓库中单个文件的文件大小历史记录？ [英] How to see the file size history of a single file in a git repository?

问题描述

有没有办法在git仓库中查看文件的大小如何随时间变化？我想看看我的main.js文件（这是几个文件的组合和缩小）随着时间的推移而增长和缩小。 解决方案

您可以使用 git show --pretty = raw< commit> 的输出创建一个脚本来获取树，然后使用 git ls-tree -r -l <​​/ code>来获得你正在寻找的blob，包括文件大小。

如果你有ruby和安装了砂砾 gem，这里有一个我扔在一起的脚本：

  require'grit'
 
如果ARGV.size< 1 
 puts'usage：file-size FILE'
 puts'从git仓库中运行'
 exit 
 end 
 
 filename = ARGV [ 0] .to_s 
 
 repo = Grit :: Repo.new（'。'）
 commits = repo.log（'master'，filename）
 commits.each do |提交| 
 blob = commit.tree / filename 
 puts＃{commit}＃{blob.size} bytes
 end 
  

示例用法（脚本的文件名为file-size.rb）将向您显示somedir / somefile的历史记录：

  myproject $ ruby​​ file-size.rb somedir / somefile 
  

Is there anyway to see how a file's size has changed through time in a git repository? I want to see how my main.js file (which is the combination of several files and minified) has grown and shrunk over time.

解决方案

You could create a script that uses the output from git show --pretty=raw <commit> to obtain the tree, then uses git ls-tree -r -l to obtain the blob you are looking for, including the file size.

In case you have ruby and the grit gem installed, here's a little script I threw together:

require 'grit'

if ARGV.size < 1
  puts 'usage: file-size FILE'
  puts 'run from within the git repo root'
  exit
end

filename = ARGV[0].to_s

repo = Grit::Repo.new('.')
commits = repo.log('master', filename)
commits.each do |commit|
  blob = commit.tree/filename
  puts "#{commit} #{blob.size} bytes"
end

Example usage (filename of script is file-size.rb), will show you the history for somedir/somefile:

myproject$ ruby file-size.rb somedir/somefile
