A fast gitignore matching library for Go.

go-gitignore

A fast gitignore matching library for Go.

This library use simple tree index for matching, so keep fast if gitignore file has many pattern.

Usage

gitignore, _ := gitignore.NewGitIgnore("/path/to/gitignore")

path := "/path/to/file"
isDir := false
gitignore.Match(path, isDir)

Specify base directory

go-gitignore treat path as a base directory. If you want to specify other base (e.g. current directory and Global gitignore), you can like the following.

gitignore, _ := gitignore.NewGitIgnore("/home/you/.gitignore", ".")

From io.Reader

go-gitignore can initialize from io.Reader.

gitignore, _ := gitignore.NewGitIgnoreFromReader(base, reader)

Simple tree index

go-gitignore parse gitignore file, and generate a simple tree index for matching like the following.

.
├── accept
│   ├── absolute
│   │   └── depth
│   │       ├── initial
│   │       └── other
│   └── relative
│       └── depth
│           ├── initial
│           └── other
└── ignore
    ├── absolute
    │   └── depth
    │       ├── initial
    │       └── other
    └── relative
        └── depth
            ├── initial
            └── other

Features

• Support absolute path (/path/to/ignore)
• Support relative path (path/to/ignore)
• Support accept pattern (!path/to/accept)
• Support directory pattern (path/to/directory/)
• Support glob pattern (path/to/*.txt)

note: glob pattern

go-gitignore use filepath.Match for matching meta char pattern, so not support recursive pattern (path/**/file).
