[英]Determine which git files have changed using Ruby?
I've got a Rails app with blog entries that I want to update from a separate Blog.git repo. 我有一个带有博客条目的Rails应用程序,我想从一个单独的Blog.git存储库中进行更新。
I envision my workflow as something like: 我将工作流程设想为:
The hitch here is finding which files have changed. 困难在于查找哪些文件已更改。 I'd like to harness Git for this, and I know I could do some awk or Perl scripting on
git diff
. 我想利用Git做到这一点,而且我知道我可以在
git diff
上做一些awk或Perl脚本。
But is there a better way? 但有更好的方法吗? I've briefly looked at Grit but can't find a good solution.
我简要看过Grit,但找不到一个好的解决方案。
Update : It turns out Grit is the best solution to this problem, at least as far as I can tell. 更新 :事实证明,Grit是解决此问题的最佳方法,至少就我所知。 Here's what I used to solve the problem:
这是我用来解决问题的方法:
desc 'Posts all entries to database'
task :post_all do
Dir.chdir REPO do
Grit::Repo.new('.').tree.contents.each do |file|
# post_entry cleans up my blog entries and posts them via Post.create()
post_entry(file.data, :text) unless file.basename =~ /\.gitignore/
end
end
end
desc 'Posts all new or changed entries to database'
task :post_new do
Dir.chdir REPO do
Grit::Repo.new('.').head.commit.diffs.each do |diff|
post_entry diff.b_blob.data, :text
end
end
end
desc 'Deletes entries from database'
task :remove_all do
Post.destroy_all
end
desc 'Synchronizes the remote blog repo and the database'
task :sync => [ :remove_all, :post_all ]
is a database really necessary? 数据库真的有必要吗? check out the jekyll gem.
查看jekyll宝石。 hundreds (if not thousands) of simple blogs use it, including two of mine.
数百个(甚至数千个)简单博客都在使用它,其中包括两个。

otherwise, grit is a good solution. 否则,砂砾是一个很好的解决方案。 i've used it for a few things and it works well.
我已经将它用于一些事情,并且效果很好。
