Validate Regular Expression
As its name suggests, this dialog box helps validating regular expressions by playing with various test inputs.
The dialog box appears in two cases:
- If you choose to validate a regular expression in your source code, the dialog opens with the current regular expression.
- If you open it from the menu , the dialog appears empty allowing you to specify both the expression and the test input.
The dialog box has the following controls:
|Regular Expression||Here you can view and edit the regular expression that you validate.|
|Options||This combo box allows you to set the regular expression options that will be used when validating your expression against the test input in this dialog.|
|Test input||Here you can type anything to test your regular expression. The matches in the input are highlighted.|
|Check lines separately||If this check box is selected, your regular expression will be applied to each new line in the test input.|
|Matches||This table lists all matches of your regular expression in the test input. You can click on the matches to locate them in the test input.|
|Insert||This button is only available if you are validating a regular expression in the source code. In this case, the button pastes the validated (or modified) expression back into the original source code location and closes the dialog box.|
|Cancel||This button closes the dialog box.|
