Regular Expression Editor

" + "

What you are currently looking at is an editor for Regular Expressions.

" + "

The upper part in the middle is the editing area, the lower part is a verification window where you can " + "try your regular expressions right away. The row of buttons is the editing actions. " + "This is actually very similar to common drawing programs. Select an editing tool to start " + "editing your regular expression, and press the mouse button in the editing area where you want " + "this item inserted.

" + "

For a more detailed description of this editor see the info pages

" + + "

What is a regular expression?

" + "If you do not know what a regular expression is, then it might be a good idea " + "to read the introduction to regular expressions.
