Textavia Regex Helper

Test JavaScript regular expressions locally with timeout protection.

Prefer the local Textavia CLI. Check availability in this order:

txv --version
textavia --version
npx textavia --version

If none of those commands work, ask the user before installing Textavia.

CLI commands

Regex test

Test a regular expression with timeout protection.

txv regex test "^[a-z0-9-]+$" "hello-world" --json

Safety

Process user data locally by default.
Do not upload secrets, logs, private files, or sensitive data to remote services.
Use --json for structured agent output.
Use canonical txv run <tool-id> commands for automation.
