Interactive regex matcher, AST token explainer, and multi-language exporter
Visual Regex Tester is a desktop pattern-matching workbench for building, debugging, and exporting regular expressions on Linux. Powered by Python's regex engine and syntax parser, it highlights numbered and named capture groups in distinct pastel tones, previews live find-and-replace substitutions, and explains every token in an interactive AST tree.
Key Features:
- Live Match Highlighter & Group Inspector: Evaluate expressions with IGNORECASE, MULTILINE, DOTALL, and VERBOSE flags, inspect numbered and named capture groups with span offsets, and test live substitution templates.
- Regex AST Token Explainer: Parse pattern structure into a human-readable token-by-token tree with quantifiers, character classes, anchors, and a visual syntax error locator with exact column pointer.
- Curated Pattern Library & Code Exporter: Browse tested patterns for Email, ISO Date, SemVer, IPv4, URL, UUID, and CSV fields, and export ready-to-run Python, JavaScript, POSIX grep -E scripts, or JSON test suites.
Disclaimer: Visual Regex Tester is an independent open-source project by TC Studio and is not affiliated with, endorsed by, or sponsored by Regex101.
