Sometimes you find multiple blank lines in your MUD output, especially if you are omitting other lines from output. The simple plugin below will omit all blank lines from your output window.

For this to work you need to go to the File menu -> Global Preferences -> General and make sure that "Regular expressions can match on an empty string" is checked.

To use, copy from between the lines below, save as Omit_Blank_Lines.xml in your MUSHclient -> Worlds -> Plugins folder, and then use the File menu -> Plugins to install it.


<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE muclient>

Is there a way to adapt this to only omit a line if it is part of a sequence of multiple blank lines?

i.e., if I receive \n\n, one of the blank lines should be omitted so that only \n remains. If I receive a single \n though, nothing should be omitted.

I figured out what I was trying to do. Here is the resulting plugin:
