in reply to use, require, do or what?

When you declare a variable with my it won't be accessible in require-d code. One alternative is to use our instead of my:
our $var; require 'library.pl'; # library.pl contains: # $var = ... print $var, "\n";
However, modifying variables this way in not a great idea. Think about what the purpose of the module is. For instance, if you are using it to compute a function, make the module define a subroutine which is called by your program when it's needed. If is being used to define constants, then consider putting it in its own namespace and exporting the values.

[Corion]: marto: Redoing something on new infrastructure sounds fun. At least you can reuse your previous experience :)
[marto]: I'm looking forwads to it. The video sources are dying, and they don't have the hardware to play them back (old tape formats, not just VHS + Laserdisc etc)
[marto]: I'll be interested to see what difference in terms of file size/quality the new codecs make. I enjoy working on things like this, so that's a bonus
[Corion]: Ah, cool! So it's not an inhouse youtube but for a wider consumption
[marto]: last time it was IE6 clients, now they're on 11, so more scope there also, in terms of UI and playback
[marto]: in house as in Company network, not internet connected (power stations and the corporate HQs)
[Discipulus]: new Monsignor party! free beverages and pizza for all you monks! and a big thanks for the patience you deserved me during these years
[marto]: congrats Discipulus
[Discipulus]: only 4k points to sundial's level ..;=)
