As @brian is mentioning in the comments the currently accepted answer by @piCookie is wrong! $_=”what’s the wrong answer?”; s/\b(\w)/\U$1/g print; This will print “What’S The Wrong Answer?” notice the wrongly capitalized S As the FAQ says you are probably better off using s/([\w’]+)/\u\L$1/g or Text::Autoformat
Any time you want to generate a list based another list: # Double all elements of a list my @double = map { $_ * 2 } (1,2,3,4,5); # @double = (2,4,6,8,10); Since lists are easily converted pairwise into hashes, if you want a hash table for objects based on a particular attribute: # @user_objects … Read more
You did a raw import. The docs for that say “Remember too that the import is not actually carried out by OODoc::File until a save and the imported data is therefore not immediately available.” I suggest you try $container2->save; and then re-load it right after importing styles and then see if Table.A1 shows up in … Read more
Currently I believe there is no Perl plugin for IntelliJ. The IntelliJ website has several tutorials on how to write plugins. They also have a special sections that is devoted to developing language plugins. I have no idea how hard it would be, but you would definitely learn a lot. I would guess that modifying … Read more
First, please use a DEBUGGING perl, if you want to inspect it with gdb. Please define “stuck”. Busy or non-busy waiting (high or low CPU), eating memory or not? With while 1 it is busy waiting. I usually get busy waiting (endless cycles) on HV corruption in Perl_hfree_next_entry() since 5.15. Non-busy waiting is usually waiting … Read more
Well, there’s definitely no way to do exactly what you can do in Perl, because Python will complain about undefined variable names and a syntax error (missing comma, perhaps). But I would write it like this (in Python 2.X): print ‘%8s %8s %8s’ % (‘date’, ‘price’, ‘ret’) If you’re really attached to Perl’s syntax, I … Read more
This may happen when perl or perl modules are installed separately along side the official packages. Environment variable can be used to switch to a different perl installation. To find out if that is the case run: env | grep PERL Having PERL5LIB or PERL_LOCAL_LIB_ROOT in the output might cause the issue. Try unsetting the … Read more
sammy, have a look at pip, which will let you do “pip install foo”, and will download and install its dependencies (as long as they’re on PyPI). There’s also EasyInstall, but pip is intended to replace that.
To use the DATA filehandle twice you need to rewind it. The tricky bit is that if you do seek(DATA, 0, 0), it’ll be positioned to the first source line, not the line after __DATA__. Therefore you need to save the position first: my $data_start = tell DATA; # save the position print while (<DATA>); … Read more
It might help to think in terms of memory addresses instead of variable names. my @a = (); # Set aside memory address 123 for a list. my $a_ref = [@a]; # Square brackets set aside memory address 456. # @a COPIES the stuff from address 123 to 456. push(@$a_ref,”hello”); # Push a string into … Read more
