Hi,

Just wanted to check a couple of things please - got  into a mind maze
with this stuff.

With syntax-patterns.txt which dialect of regular expressions is being
used please?

In that dialect does .* mean  anything many times?

Can () be used to choose which part of an expression is colourised?

For e.g.

skyblue N .*\{(http[s]://.*)}

    -- Would colour only the actual address?

Paul
