REGULAR EXPRESSIONS
• Multiline mode - If Multiline mode is selected, rather than searching through the test cases lineby-line,
regular expressions will be searched on all lines at once. This is useful for test cases that
wrap to the next line. This works just as if you had entered \om on the SlickEdit® command line.
• Case sensitive - If Case sensitive is selected, the regular expression search will be case
sensitive. This option is on by default.
• New expression button - To clear the tool window of all entries in order to start a new evaluation,
click the button at the top of the tool window labeled New expression.
• Open a saved expression button - To open an expression that you have already saved, click the
folder button at the top of the tool window labeled Open a saved expression.
• Save the current expression button - To save the current expression, click the diskette button at
the top of the tool window labeled Save the current expression. Both the expression and the test
cases will be saved to a file. The default extension is .regx.
• Save as button - To save the current expression with a different file name than what has
previously been saved, click the button at the top of the tool window labeled Save the current
expression as.
Regular Expression Syntax
This section provides charts of regular expressions for each supported syntax (Brief, Perl, SlickEdit, UNIX,
and Wildcards), including examples.
NOTE There are some differences between our implementation of these syntaxes and those
elsewhere.
Brief Regular Expressions
Brief regular expressions are defined in the following table.
