Report a problem
- Describe the action that fails.
- Include the expected result and the actual result.
- State the browser, operating system, flavor, and flags.
- Reduce the pattern and input to a synthetic example.
- Include the exact error text.
- If sharing a workspace, use a stable numbered version.
For a runtime mismatch, also include the target language and regex library version. A screenshot can show a layout problem, but copyable text is necessary to reproduce a pattern problem.
Practice with the quiz
The regex quiz requires a free account on the public service. Its tasks use PCRE2 and can include matching or substitution requirements.
- Sign in and open an available task.
- Read its exact requirements.
- Enter the pattern and any required substitution.
- Select Submit to inspect the result.
