Code Intelligence Tools
Use these utilities to understand or query structured data and diagnose code behavior. Test a regular expression against representative input, inspect a stack trace for likely failure points, or build JSONPath, XPath, and CSS selector expressions. Test expressions against edge cases in your own environment before relying on them in production.
What are Code Intelligence Tools?
Code intelligence utilities help explain, test, or build expressions used to inspect source and data. This category includes selector, regular-expression, JSON-path, XPath, error, and stack-trace tools.
Who uses these tools?
Useful when a selector returns no nodes, a pattern behaves unexpectedly, or an error trace is difficult to scan. They can help both while learning a syntax and while debugging a concrete example.
Common tasks in this category
- Try a regex, CSS selector, JSONPath, or XPath against sample input.
- Read an error or stack trace in a more structured form.
- Check generated expressions against edge cases before reuse.
