Reverse Regular Expression
Reverse regular expression used for reverse checking of the text before point. Reverse regular expressions written in reverse order, so for example if normal regular expression looks like this:
\s+[abc]def
than same reverse regular expression will look like this:
fed[abc]\s+
In HippoEDIT they are used in all lead conditions for Keywords, Words or block Regexp definitions.
<Regexp open=""" open_lead="=elyts" close="""/>
In example above, open_lead checks if “ is preceded by word style=.
