Well, on my pc {^#} was faster

% time {regsub {^#} #chan chan} 10000
3.0633 microseconds per iteration
% time {regsub {#} #chan chan} 10000
3.2233 microseconds per iteration
% time {regsub {^#} #chan chan}
27 microseconds per iteration
% time {regsub {#} #chan chan}
28 microseconds per iteration

But, it doesn't really matter, the difference isn't that big or near to big

Interrestingly, on 100 iterations {#} is faster:

% time {regsub {^#} #chan chan} 100
3.53 microseconds per iteration
% time {regsub {#} #chan chan} 100
3.37 microseconds per iteration

They depend entirely on the efficiency of the computer they are being tested on.

And I really can't see where microseconds will matter terribly (nor can I imagine a script where the exact same command is given in a procedure a hundred times in a row).

Maybe those time tests aren't really that accurate.

If you want it to still be neat but faster:
Code:
regsub {^#} $chan {} chan
This will save time since it will check only the first character if it matches '#' instead of the whole string.

I would have thought so as well, until I ran the time tests.

Code:

% time {regsub {#} #chan {} chan} 1004.9 microseconds per iteration% time {regsub {^#} #chan {} chan} 1005.05 microseconds per iteration

Maybe those time tests aren't really that accurate.

.. and a whole 2 microseconds is going to be a total disaster? Good grief! DragnLord's solution is not only neater but cuts code length. I prefer neat and short code.

what about a simple [string trimleft $chan #] or [string map {# ""} $chan]? No need for any always slow regex.

Code:

% time {set chan [string trimleft #channel.name #]} 1002 microseconds per iteration% time {set chan [string map {# ""} #channel.name]} 1004 microseconds per iteration% time {regsub {#} #channel.name {} chan} 1007 microseconds per iteration

First might make troubles when using with opnotices which target is @#channel, but if you want to strip then @# anyway, you will have no trouble with it.

Code:

regsub {#} $chan {} chan

Would be faster. It is neater also

I got this solution JUST find out:

Code:

regsub -all "#" $chan "" channelname

Bad, not safe or?

Hi all,

I want to execute an MySQL query with the channelname in the query, like join.php?chan=$chan.

All sounds pretty neat, but MySQL / PHP does not support the # sign.
My question is, how do I remove the # in front of the channel to execute the MySQL query:

Example
-----------
Bot is in #T-Xorcist
The query will be join.php?chan=#T-Xorcist
The query MUST be join.php?chan=T-Xorcist

Can anyone help me out with this issue?

Thanks in advance.
