PDL::Config(3pm)

💖 NAME 💖

okay so bestie, this is PDL::Config — a manual page from the User Contributed Perl Documentation collection, living in section 3pm. And what is it, you ask? It's literally just a vestige of configuration for PDL. That's the whole job description. A ghost. A vibe. An artifact. 👻✨

🌸 DESCRIPTION 🌸

so back in the day, this thing was used for control of, and then storage of, various options for building PDL. like, it was the girl handling the settings, then the girl holding the settings. a whole arc. 💅

but no cap — a bunch of those options have since been replaced with environment variables. so if you're looking for them here, they're not here anymore, they moved out. 🦋 where'd they go? consult the various Makefile.PLs in the GD, GSL, etc modules. that's your forwarding address, bestie. go look there, not here. 🙈

✨ how do i check if a module is installed tho ✨

great question, main character. use this boolean expression, it's iconic:

eval { require PDL::Module::Name; 1 }

that's it. that's the whole trick. it ate and left no crumbs. 🍓

lowkey important: it's a boolean expression, so it tells you true/false whether the module is there. swap in whatever PDL::Module::Name you're actually curious about, iykyk. 🎀

and that's the whole page, gorgeous. nothing was skipped, nothing was invented, we kept every crumb of the original. 🫶
