Re^2: how to split a string at [ ?

Hello!

Thanxs all a lot for the many suggestions. Because it seems the more felxible, I started to try with the above Regexp::Common.

I modified it a littel bit.

$tmp[5] = "BCInletTemperature = 90[C]";
print "$tmp[5] xx\n";
$temp = $tmp[5] =~ m{ = \s+ ($RE{num}{real}) \[ }xms;
print "xxx $temp xxx\n";

But running it gives:

Name "charnames::CARP_NOT" used only once: possible typo at /usr/lib/p
+erl5/5.18.2/Carp.pm line 437.
Name "Regexp::Common::delimited::CARP_NOT" used only once: possible ty
+po at /usr/lib/perl5/5.18.2/Carp.pm line 437.
      BCInletTemperature = 90[C] xx
xxx 1 xxx

Perl is

perl --version

This is perl 5, version 18, subversion 2 (v5.18.2) built for x86_64-li
+nux-thread-multi
[download]

at openSUse Leap 42.3.
Do I need a newer version?

Do I need a newer version? No, but you do need to remember to put the brackets around `$temp` when you assign to it in order to ensure list context. You should also provide an SSCCE rather than 4 lines out of context as something could be wrong in the code you aren't showing too.	[reply] [d/l]

Are you perhaps using `perl -w` on the command line or on the shebang line? In that case, see What's wrong with -w and `$^W` and `use warnings;` instead. The other issue with that code is that `$string=~/(regex)/` won't return the match(es) unless you use it in list context, but `my $temp = ...` puts it in scalar context. To put the right-hand side into list context, use `my ($temp) = $string =~ /(regex)/;`.	[reply] [d/l] [select]
