Rex::H...mLookup(3pm)

🎀 NAME 🎀

Rex::Helper::Rexfile::ParamLookup — bestie, this is the little command that manages your task parameters. 💅

Not only that, but it also registers those parameters as template values, so they're just… there for you, ready to vibe in your templates. ✨

And plot twist: this module will also peek inside a CMDB (if one exists, like, if you have one) to hunt down a valid key. 🕵️‍♀️ No cap.

🌸 SYNOPSIS 🌸

task "setup", sub {
  my $var = param_lookup "param_name", "default_value";
};

Look at her go. Iconic. 💖

🦋 LOOKUP 🦋

Okay so here's the tea on how the lookup actually goes down, fr fr:

• First, param_lookup checks the task parameters for a valid parameter. That's step one, always.
• If none is found, and if a CMDB is being used, it will look inside the cmdb. 👀

And here's the part that's lowkey genius — the naming order, okay, stay with me:

If your module is named "Rex::NTP", then it will first look to see if the key "Rex::NTP::param_name" exists. 🌈

If it doesn't exist, then it checks for the key "param_name". 💫

So it's giving module-namespaced-first, plain-name-as-fallback. Main character energy from a lookup function, honestly. 👑

---

tl;dr: task params → CMDB (if present), and when it hits the CMDB it tries "Your::Module::param_name" before it ever slums it with plain "param_name". 🫶

That's the whole page, bestie — she's short but she's mighty. 💜
