What is Git Ignore Pattern Tester?

Git Ignore Pattern Tester evaluates .gitignore rules against a path list and reports which files or directories are ignored or included, including matched rule lines.

Can this tool debug gitignore negation rules?

Yes. It supports negation patterns and reports when parent ignored directories still block nested re-inclusion.

How do I test directories vs files?

Use one path per line. Add a trailing slash or use the dir: prefix for explicit directory testing behavior.

Does this matcher support wildcard patterns like * and **?

Yes. It supports common wildcard behavior for path and basename matching, including recursive globstar patterns.

Is this .gitignore tester private and free?

Yes. It is free to use and runs in your browser, so your rules and path lists stay on your device.

Build Artifact and Cache Control

Test exclusion patterns for dist, build, coverage, and cache paths before CI pipelines or release automation runs.

Debug Missing Files in Git Status

Quickly diagnose why files do not appear in git status by tracing the rule and line that controls ignore behavior.

Understanding Git Ignore Patterns Validation

What is Git Ignore Patterns Validation?

Git Ignore Patterns validation is the process of checking .gitignore wildcard and negation rules tested against project file and directory paths files (.gitignore) for syntax errors, structural issues, invalid values, duplicate keys, and specification compliance — helping you catch problems before deployment. Git Ignore Patterns is widely used for validating ignore and unignore behavior before committing gitignore changes that can hide files or bloat repositories. Our free test gitignore patterns tool checks your content instantly in your browser. Whether you need to gitignore pattern matcher for repository cleanup, monorepo ignore-policy QA, CI artifact exclusion checks, and safe negation rule verification, our tool finds errors accurately and privately.

How Our Git Ignore Pattern Tester Works

Instant Browser-Based Validation: Click the "Validate Git Ignore Patterns" button. Our tool analyzes your content entirely in your browser — no data is sent to any server, ensuring complete privacy.
Review Detailed Error Reports: View a comprehensive list of errors with line numbers, descriptions, and severity levels. Fix issues with pinpoint accuracy using our clear error messages.

What Gets Validated

Syntax Correctness: Checks for proper syntax including balanced brackets, correct string quoting, valid escape sequences, and proper key-value pair formatting.
Data Types: Validates integers, floats, booleans, strings, datetimes, arrays, and inline tables conform to the Git Ignore Patterns specification.
Structural Integrity: Detects duplicate keys, conflicting table definitions, invalid table headers, and malformed sections.
Line-by-Line Reporting: Every error includes its exact line number and a clear description, making it easy to find and fix issues in your Git Ignore Patterns files.

Yes! Our test gitignore patterns tool handles files of any size. Since all processing happens in your browser, performance depends on your device, but modern browsers handle even very large Git Ignore patterns files efficiently.

It evaluates .gitignore rules against your file path list and reports which paths are ignored or included, including the exact rule line that matched.

Yes. Negation patterns are evaluated in order, and the report highlights cases where parent-directory ignore rules still block nested re-inclusion.

Yes. Add one path per line. Use trailing slash or a dir: prefix to test directory behavior explicitly.

If a parent directory remains ignored, a nested file-level negation may not re-include the file. You must unignore parent directories first.
