jignore

jignore is a Java library that provides ignore rule parsing and matching for file paths. It is designed to help developers exclude files and directories according to patterns, in a manner similar to .gitignore rules.

Pattern syntax and matching: jignore supports common features such as wildcards, recursive matches with **, directory-level matching, and negation lines starting with !. Patterns can be read from files or streams and compiled into an efficient matcher. The matcher determines whether a given path should be ignored, and can be used to filter collections of files or directory listings.

Usage and integration: typical usage involves loading patterns from a .jignore or .gitignore file, constructing an ignore rule set, and applying it to a list of files produced by a directory walk. The API usually provides methods to test a path individually or to filter a stream of paths, with performance suitable for build tools and packaging workflows. It integrates with Java IO and NIO APIs and is intended for use in tasks that require selective file processing.

Development and ecosystem: jignore is an open-source project hosted on public repositories and is commonly available as a dependency via Maven Central, Gradle, or other Java package managers, enabling easy inclusion in Java projects. The project is maintained by contributors and subject to typical open-source governance.
