GitIgnore PHP

GitIgnore PHP is a lightweight yet powerful PHP library for parsing and managing gitignore‑style rules. It provides a robust engine to interpret .gitignore patterns—including advanced brace expansion, recursive wildcard matching, negation rules, and configurable case sensitivity. Use GitIgnore PHP to filter files in a repository based on ignore rules, integrate with file processing systems, or build custom file parsers.

Features

• Gitignore Parsing:
  Automatically scans your project directory for .gitignore files (and optionally additional ignore files) and loads their rules.

• Advanced Glob Pattern Support:
  Handles standard wildcards:

  • * – Matches any sequence of characters (except directory separators).
  • ** – Matches across directory boundaries.
  • ? – Matches any single character.

• Brace Expansion:
  Write compact rules such as *.{js,css,html} that expand to multiple patterns (*.js, *.css, and *.html). Nested brace expressions are also supported.

• Negation and Rule Precedence:
  Supports negation rules (using !) and complex negation chains so that you can re‑include files that might be excluded by earlier rules. Rules are applied hierarchically based on their directory depth.

• Directory‑only Rules:
  Patterns ending with a slash (e.g. build/) mark directories (and all their contents) as ignored.

• Configurable Case Sensitivity:
  Choose between case‑sensitive or case‑insensitive matching via the constructor.

• Multiple Ignore Files:
  While the default is to load .gitignore files, you can specify additional files (e.g. ['.ctreeignore']) to merge extra rules.

• Seamless Symfony Finder Integration:
  Designed to work in tandem with Symfony's Finder component, making it easy to filter entire file sets.

Installation

Install GitIgnore PHP via Composer:

Usage

Basic Usage

Load a project's gitignore rules and determine whether a file should be ignored:

Using Additional Ignore Files

By default, only .gitignore files are loaded. To include extra ignore files (for example, .ctreeignore), pass an array as the third parameter:

Testing Brace Expansion

The library supports compact rule definitions using brace expansion. For example:

Filtering a Git Repository

Combine GitIgnore PHP with Symfony Finder to list all files that are not ignored:

API Reference

GitIgnoreManager

• __construct(string $basePath, bool $caseSensitive = true, array $additionalIgnoreFiles = [])
  Initializes the manager by scanning the base directory for ignore files. By default, only .gitignore is loaded; additional files can be specified.

• accept(SplFileInfo $file): bool
  Determines whether the specified file should be accepted (i.e. not ignored) based on the loaded rules.

• matchPattern(string $pattern, string $subject): bool
  Checks if the given ignore pattern matches the provided subject string.

PatternConverter

• convertPatternToRegex(string $pattern): string
  Converts a gitignore‑style pattern into a regular expression (without delimiters), handling escapes, wildcards, and character classes.

• expandBraces(string $pattern): array
  Recursively expands brace expressions (e.g. *.{js,css,html}) into an array of individual patterns.

• patternToRegex(string $pattern): string
  Converts a gitignore pattern into a complete regular expression with delimiters and anchors, ready for use with preg_match().
