Re: How to zero-pad hex values in sprintf()?

in reply to How to zero-pad hex values in sprintf()?

      am I crazy or do printf() and sprintf() have no way to return, say, 0F instead of just F?

I'm not a psychiatrist and never played one on TV so I can't judge if you're crazy or not. But check out this sniglet of code.

$ perl -e 'printf "%0.4x\n",128;' 0080

[Corion]: Discipulus: I'm slowly migrating my code to require 5.8.x ;) Most of my code works on 5.6, but Filter::signatures requires 5.10 I think
[Corion]: 5.14 is also a good target, widely available and fairly stable. Also, over five years old, which doesn't push people into a needless upgrade cycle
[Discipulus]: yes I saw your efforts Corion but the pain is worth?
[Corion]: Discipulus: IMO it's not that much pain, but most of the systems I use have a Perl 5.14 or newer on them nowadays
[marto]: the question is more, is Padre still the way new users should be directed?
[Discipulus]: ah ah I have all 5.26 atm but I play alone..
[Corion]: Except this RHEL box, which comes with Perl 5.10.1 , but there I installed my own 5.20.3 for the real Perl programs we run ;)
[Corion]: marto: I used Padre for some time but then switched to Notepad++, since all the funky features I wanted to put into Padre couldn't be made to work, and/or I lost interest :)
[Discipulus]: indeed marto I dunno. I tested once and many years ago. But I'm not the programmer yardstick. I try to install Padre via cpan now just to add a line about it in the issue. Strawberryperl all life long!
[marto]: yeah, when I worked on Windows I did use Np++ all the time

    Should cpanminus be part of the standard Perl release?
