Hi,
It's my first time playing with Text::Balanced module.
From the code below (a quick test script I wrote..),
shouldn't $next contain '#name#' after the call to
extract_delimited() sub?
As of now, the subroutine simply sets $@ indicating this:
"Not a delimited pattern, detected at offset 0".
My thinking was that the extract_delimited() sub would pull out 'first'
delimited substring inside a given larger string. This is
not the case, however ;-). So, for that matter, how do I do
it using this module? I'm not sure which one of the imported
methods I should use to achive the desired result (say, pull
out next '#' delimited substring).
use Text::Balanced qw (
extract_delimited
extract_bracketed
extract_quotelike
extract_codeblock
extract_variable
extract_tagged
extract_multiple
gen_delimited_pat
gen_extract_tagged
);
my $source = 'Hello World, #name#!';
my ($cfml_expr_match, $next);
#eval {
$cfml_expr_match = gen_delimited_pat(q{#},q{#});
$next = extract_delimited($source, '#', '', '#');
#};
if ($@) {
print "Hmm.. got this: $@\n";
}
# some code here...
print "\n";
Note: I've uncommented eval{...} since it would clear the $@
variable, therefore, not letting me to check on the status
of a call to a Text::Balanced method. Any idea why this is
a case? Sorry for yet another loosely related question ;-).
