git ignore all files except one extension and folder structure

Question

This is my .gitignore:

#ignore all kind of files * #except php files !*.php 

All I want is to ignore all kind of files except the .php ones, but with this .gitignore I'm also ignoring folders...

Is there a way to tell git to accept my project folder structure while keeping the track only of the .php files?

It seems like now I can't add folders to my repo:

vivo@vivoPC:~/workspace/motor$ git add my_folder/ The following paths are ignored by one of your .gitignore files: my_folder Use -f if you really want to add them. fatal: no files added 

Answer 1

This is simple, just add another entry !my_folder in your .gitignore

#ignore all kind of files * #except php files !*.php !my_folder 

The last line will take special care of my_folder, and will not ignore any php files within it; but files within other folders will still be ignored because of the first pattern of *.

EDIT

I think I misread your question. If you want to ignore all files except .php files, you can use

#ignore all kind of files *.* #except php files !*.php 

This will not ignore any file which doesn't have an extension (example: if you have README and not README.txt ), and will ignore any folder with a . in its name (example: directory named module.1).

FWIW, git doesn't track directories, and hence there is no way to specify ignore rules for directory vs file

Answer 2

I had a similar problem; I wanted to whitelist *.c, but the accepted answer didn't work for me, because I had files that didn't contain ".".

So for those who want to handle that:

# ignore everything *  # but don't ignore files ending with slash = directories !*/  # and don't ignore files ending with ".php" !*.php
