Re: [code] [textadept] changing text color in message buffer

Hi Jay,

I'm not sure it's necessary to loop through the buffers to change the
styling, consider the following snippet:

events.connect(events.RUN_OUTPUT, function(lexer, output)
    if output:sub(1, 1) == ">" then
      ui.print(">>>> "..output)
    return false -- prevent default event from being applied
end, 1)

It happens before the default event for printing an output line, checks
whether the first line is ">" and prints it differently, otherwise just
the line. Styling it differently could happen in a similar way, as
Mitchell described.

Hope this helps and let us know if you have any questions!
