go-pathspec implements gitignore-style pattern matching for paths.

There are a few alternatives, that try to be gitignore compatible or even state gitignore compatibility:

go-git states it would be gitignore compatible, but actually they are missing a few special cases. This issue describes one of the not working patterns: go-git/go-git#108

What does not work is global filename pattern matching. Consider the following .gitignore file:

# gitignore test file
parse.go

Then parse.go should match on all filenames called parse.go. You can test this via this shell script:

mkdir -p /tmp/test/internal/util
touch /tmp/test/internal/util/parse.go
cd /tmp/test/
git init
echo "parse.go" > .gitignore

With git parse.go will be excluded. The go-git implementation behaves different.

monochromegane's go-gitignore does not support the use of **-operators. This is not consistent to real gitignore behavior, too.
