abego RegExpCalculator

The abego RegExpCalculator allows you to interactively test your regular expressions.

  1. Enter your regular expression in the "RegExp:" line
  2. Enter one sample text the RegExp should match in the "Input text:"
  3. Check if the text is correctly matched by looking at the "Result"
  4. If the text is not correctly matched modify the "RegExp" until the bug is fixed.
  5. Once you found the "correct" RegExp verify it also works with other sample texts.
  6. Don't forget to check that the RegExp does not match "too much". Try out some "invalid input text" and check it is not matched.
RegExp:   / /
Input text: (to be matched with the Regular Expression)
Result: (the list of matches, as returned by re.exec(theInputText))
