Learning EPIC5; alias differences

[Jeremy Chadwick]

I've been tinkering around with EPIC5 for a few days, and there's one
difference which has been the source of some confusion for me. Take
for example the following alias on EPIC4/ircII:

alias t //topic

This has two capabilities: a user can type "/t" and see what the current
topic is and when it was set, or they can type "/t hello bob" and set
the current topic.

This alias breaks on EPIC5, with "/t" by itself setting the topic to
literally nothing. The only solution I found was to do this, which
seems a bit unnecessary:

alias t { if ([$0]) { //topic $* } { //topic } }

Is there a more intelligent way of accomplishing what used to "just
work" in EPIC4?

If you do it like this:
/alias t (args) {//topic $args;}
it will not change the behaviour.

Also you should not check ifs like if ( [$0]) since if you would try
to do /t 0 the if would evaluate that to false. Instead do if ( @ ) or
if ( # )
(@ expands to strlen and # expands to word count)

Thanks much for this -- works like a charm! :-) I was just starting to
read the Wiki page on arguments, then I got your mail...
