Visual REGEXP project can easily design and debug regular expressions by providing a graphical visualization of the expression and its matches on a sample of your choice.
Version restrictions:
- some regexp can consume a lot of CPU time. This seems to be caused by the use of -all, -inline and -indices flags together.
- when a subexpression is not matched (empty match), the last character of the previous match are coloured. This is due to a problem in Tcl (bug submitted to Scriptics).
Enhancements:
- new version done by Martin Lemburg. Many thanks, Martin.
- it is now a tcl 8.5a4 starpack
- GUI layout changed to be based on a paned window
- GUI code looks different, to be more ergonomic
- the informational labels (replacements & matches) are now sunken
- there are now additional the "first" and "last" navigation buttons
- there is a new option to navigate through matches or matches and submatches
- the displayed count of matches is changed to display the current and the count of matches used for navigation (probably changes, if the new navigation option is changed)
- the replace widget is disabled on startup
- the tcl console is added to the help menu
- the key bindings inside the regexp text widget changed a bit to allow for expanded regexp (-expanded or (?x)) to contain tabs and newlines. Tabs are created with Control-Tab and newlines with Control-Return. Additional with Control-C|V|X (not c|v|x) it is possible to use the clipboard like with Control|Shift-Insert, Shift-Delete.
