.gitignore Generator
.gitignore Generator: Expands fixed node, python, and macos pattern lists, removes duplicate lines, and comments unknown labels; it does not fetch GitHub templates or inspect repositories.
About this .gitignore generator
.gitignore Generator — browser-based utility.
How this tool works
Expands small fixed bundled pattern lists for node, python, and macos selections and deduplicates the result. It does not retrieve official GitHub templates or validate .gitignore precedence and negation semantics.
- Split and lowercase whitespace- or comma-separated labels.
- Expand the three fixed template lists or comment an unknown label.
- Preserve first occurrence order while removing duplicate output lines.
Worked example
Scenario: Expand the three bundled environment templates.
Sample input:
Processing: Split the selections, map the three fixed pattern lists, then deduplicate.
Illustrative output:
Limits and verification
It does not fetch templates, inspect repositories, validate .gitignore precedence or negation semantics, escape names, validate patterns, or write files.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does Gitignore Generator choose patterns?+
It splits whitespace- or comma-separated labels, lowercases them, expands fixed `node`, `python`, and `macos` lists, then removes duplicate lines in first-seen order.
What does `node python macos` produce?+
The page output includes `node_modules/`, `.venv/`, and `.DS_Store`, with the other fixed Node and Python entries. This checks bundled selection expansion, not repository discovery.
What input and rule limits apply?+
Unknown labels become `# label` comments. The tool does not inspect project files, fetch GitHub templates, recognize frameworks, validate ignore syntax, or model precedence and negation rules.
What does the browser test establish for selected labels?+
It enters the labels and checks the generated page output; its tool request log contains no request carrying the selected labels. It does not make an absolute privacy claim about page assets, extensions, or the browser environment.
