"subst -nobackslashes -nocommands -novariables" ?

2005-02-05T08:11:30-04:00

I ran a quick test on it (the way he has it written) and it does indeed seem to do nothing. I'm not even sure if the syntax is right. It looked to me (from reading up on it) as though $text is supposed to be within braces i.e. subst -nocommands {$text}

I taked that piece from Channel Guardian by DrN.. One of the most popular protection script(8396 downloads) .. (see online source)

I trying to do somethink better, i counted 6 "subst -nobackslashes -nocommands -novariables .." in that script, so i was been thinking what that is somethink important.. After reading the manual i still don't understand for what author ussing it.. So i was tried to get answer here.

So, it's do nothing ussefuly in this case? Just wasting cpu ? Cool ;)
Thanks you all!

i know, but i don't think it was the intention of using them all i think he is learning tcl and trying to find out the use of the command

i think he just forgot a '$' infront of the word text

It would still do nothing. (subst doesn't modify variables...it returns the string fed to it with substitutions performed (none if all the switches are used))

It does nothing but waste some cpu. The string "text" doesn't contain any characters that would trigger substitutions, and the return value (text) is discarded. The author is either stupid or trying to confuse you.

A rough guess would be that the piece of code Adrenalin posted is from some sort of channel protection script and is used for excessive "away" messages in the channel and the use of -nocommands -novariables -nobackslashes could be to get around the varied weird and wonderfull messages that are created these days (along with equally weird and wonderfull nicks) all using characters that eggdrop most of the time chokes on.

Ofloo, the posted code uses -nocommands -novariables -nobackslashes all at once.

If it only used one of them, then yeah, it would have a point.. but all 3?

well its like for example to evaluate variables but not execute or execute but not resolve variables and so on .. for example

Code:

set new_test blahset a newset b testputs [subst -nocommands $a_$b]

otherwize it would say $a_ is not a variable !

i used it to create dynamic array names.

name_Array(something) data

ex:
set $nick_$chan($host) "+o"

could be done more efficient but just to give you an idea..

I don't think Adrenalin was asking for the man page... more like, what is it DOING? In other words, if you call subst and tell it not to evaluate backslashes, commands, or variables, what is the point? What does it DO? Anybody have an idea? My initial guess is... it does nothing.
