what's the intended behaviour of ${variable:a:b}?
given that ${exten} = 501234
until yesterday ${exten:2} would give '1234'
with current CVS ${exten:2} is '50' while ${exten:2:4} is '1234'
how do I just strip characters/digits in front of the variable without
specifying a length?
I was doing things like:
exten => _00.,1,Goto(context,${EXTEN:2},1)
thanks,
lele
the handler for ${exten:2} is commented out from current
cvs (pbx.c line 749).
I think that mark is adding substring support with double :
syntax, but that broke the single : syntax.
You can use ${EXTEN-1} ,that works, although is
deprecated.

The problem is here:
if ((first=strchr(cp3,':'))) {
*first='\0';
offset=atoi(first+1);
if ((second=strchr(first+1,':'))) {
*second='\0';
offset2=atoi(second+1);
} else {
offset2=offset;
offset=0;
}
If you have a a double : you get from first
to the last offset. If you have a single :
you get only the first offset+1 . That must
be fixed to handle the full strlen if have
only a single :
That's all.
hope mark fix that (or is a feature).

It's fixed now.> what's the intended behaviour of ${variable:a:b}?it's the same as substring application> given that ${exten} = 501234 > until yesterday ${exten:2} would give '1234'and it does now> > with current CVS ${exten:2} is '50' while ${exten:2:4} is '1234' > > how do I just strip characters/digits in front of the variable without > specifying a length?you can do ${variable:a} or ${variable:a:1000} :) Martin> > > I was doing things like: > exten => _00.,1,Goto(context,${EXTEN:2},1) > > thanks, > lele > > > > > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users >
