Git ignore all except subfolder

问题:

I searched through other questions but can't find a working solution for my project. Having a Magento project, I want to exclude everything except this:

/app/design/frontend/default/theme_name # and obviously all subfolders
/skin/frontend/default/theme_name # and all subfolders

I've tried a lot of combinations but without luck. Currently I'm stuck with this .gitignore file:

*
!/app/
!/app/*

app/*
!/app/design/
!/app/design/*

But it doesn't work recursively below the design folder. It only added a test file inside the design folder that I created.

Look at my answer here: Can't understand how gitignore ignores the folders

Quoting from that:

The following discussion was helpful: http://git.661346.n2.nabble.com/negated-list-in-gitignore-no-fun-td1675067.html , especially the following from Linus:

That's by design. You've chosen to ignore those directories; they match "*" themselves. Thus, 'git add .' doesn't descend into them looking for files.

So basically, for each level you have to go in, unignore that folder, and ignore contents within that folder.

Also, you should look at having .gitignore at subdirectory rather than at root level only as it becomes pretty complex if you have to go to the subdirectory level from the root .gitignore because of the explanation above, whereby for each level, you have to unignore the folder and then ignore the contents and so on.

回答2:

Did some research here. What worked for me was:

/*
!/directory
!/another
/another/*
!/another/directory

With this subdirectories of /directory were tracked correctly. Curiously it doesn't work with either only / or only * on the first line - I am not sure why.

回答3:

/**
!/**/
!/app/design/frontend/default/theme_name/**
!/skin/frontend/default/theme_name/**

Explaination:

1. ignore all files and folders, recursively (note the double asterisk).
2. exclude all folders, recursively (git by design will not commit empty folders, which a folder full of ignored files is counted as. We need this so that the next two excludes work)
3. exclude all files and folders, recursively, from this location.
4. exclude all files and folders, recursively, from this location.

I usually do this to sub-folders, so I don't know if the first line will work.
