Worked example
The sample matches src/app.js, excludes vendor/lib.js, and leaves .hidden.js unmatched unless dotfiles are enabled.
Method
micromatch processes the complete positive/negative pattern list and reports membership for each pasted path. No disk or filesystem is read.
Limits
Paths ≤100,000 characters / 1,000 lines. Patterns ≤10,000 characters / 30 lines, each ≤300 characters and ≤20 brace delimiters. No brace expansion into filenames. Normalization converts Windows separators; literal mode treats backslashes as glob escapes. This is micromatch syntax, not exact Bash shell expansion.
All work stays in this browser. Each disposable worker is terminated after 2.5 seconds or cancellation. Inputs and processing logs are not sent to analytics.
Your inputs stay on this device. Only optional, consented page visits are measured. Input values, files, filenames and processing logs are not sent to Analytics.
When switching languages, text, settings and selected files are temporarily kept on this device. Transfers are removed after restoring; interrupted transfers are cleaned up on a later visit. Inputs and files are never uploaded.
