Axiom Regex Visualizer

Regex visualizer — parse any regex and visualize its structure (groups, quantifiers, anchors, character classes). Use when you need to understand or document a regex. Pure stdlib, no LLM.

Version: 0.1.2 Axioma Tools

Parses regular expressions and shows their structure visually.

What this skill does

• Visual tree of regex components
• Plain-English explanation of each part
• Highlights groups, quantifiers, anchors
• Supports Python re syntax (basic + extensions)

When to use this skill

• ✅ Understand a regex you didn't write
• ✅ Document a complex pattern
• ✅ Debug regex matching issues
• ❌ Test if regex matches a string (use re.match)
• ❌ Support Perl/PCRE-only features

Usage

python3 axiom_regex_visualizer.py "^(?:[a-z0-9!#$%&*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&*+/=?^_`{|}~-]+)*)@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?$"

from axiom_regex_visualizer import parse, explain
tree = parse(r'\b\d{3}-\d{4}\b')
explain(tree)  # 'Word boundary, exactly 3 digits, dash, exactly 4 digits, word boundary'
