Example of the KDE regular expression widget
The following is a number of screen dumps of the Regular Expression widget
I'm working on for KDE.
The widget is now part of KDE.
To build a regular expression, the user must press the buttons in the left
part of the screen and afterwards press at the wanted location in the area
at the right part of the screen. The widget can support the full range of
Qt3 regular expressions.
Example - Section regular expression
This regular expression may be used by for example Emacs to state what a
LaTeX header looks like (Note the syntax is however Qt3 not Emacs syntax of
Example - Match mail from a mailing list
This regular expression may be used by a mail filtering tool like
procmail. The regular expression should then match the header of a letter.
Example - Regexp for all my possible email addresses
A Mail client might like to know which mails are sent by you. This might be
done with a regular expression stating which from lines you send mail from.
Example - Emacs outline mode regexp for HTML headers
This is an example where I think the regular expression fills to much
screen space for so little. It is an other example of a regular expression
from my Emacs outline definition. It matches the beginning of a header
Example - Regexp for valid C variable names
Telling the regular expression widget about character ranges is done using
a pop up menu. This menu can be seen below.
When the user has pressed OK on this window, then the window will
disapear and the regexp dialog will be updated. This can be seen in the
next screen dump.
