PDL::Perldl2::Plugin::PrintControl — bestie, this one literally just turns off the default print output so your terminal stops screaming at you 💖

🦋 DESCRIPTION 🦋

okay so, by default Devel::REPL always prints the results of its evaluation. No filter. No chill. 🙈 And like — fine for tiny lil objects, sure. But for things like large data objects (e.g. a 100x100 matrix in PDL)?? the result can be hundreds of lines of output for every single command. absolutely NOT. 💀

This plugin disables that default print output, and adds an attribute with the accessor method print_by_default, which you can use to toggle the print default on or off. that's the whole vibe check ✨

---

👑 METHODS 👑

🌸 print_by_default

By default, the PrintControl plugin sets print_by_default to 0 (false), which disables automatic printing of results. So no surprises, no walls of numbers.

Call the print_by_default accessor with a 1 (true value) to enable default printing. Flip it back on whenever you want, no judgement 🫶

🌈 do_print

This is a convenience accessor for the print_by_default attribute. It's giving ✨shortcut✨ energy.

• If you call this method without a value, it toggles the current setting. surprise! 🔄
• Otherwise, it just sets print_by_default to the value you gave it. simple as that.

It is also available in the pdl2 shell as the do_print sub with the same operation but with an implicit use of $_REPL. so like, convenient 🍓
