✨ MESSAGE(9) ✨ — bestie, it's a HAL component 💖

okay so real talk, this is message from the HAL Component section of the manual (section 9, iykyk). It's literally just... a component that shows a message. That's the whole vibe. 🎀

🌸 NAME 🌸

message — Display a message 💅

🦋 SYNOPSIS 🦋

loadrt message [count=N|names=name1[,name2...]] [messages=N]
  • messages — the actual messages you wanna display. Here's the thing bestie: they go in a single set of quotes, comma-delimited, all together like a little friend group. There's an example in the Description section below, go look 👀. Now listen: if you give more messages than count or names, the extras just get ignored, no drama, they're not invited. But if you give fewer messages than count or names?? 🚨 error raised, component will not load. Not even a little bit. It just refuses. periodt.

💖 DESCRIPTION 💖

So the whole point: it lets HAL pins trigger a message. Iconic behaviour honestly. Here's the example hal commands fr fr:

loadrt message names=oillow,oilpressure,inverterfail messages="Slideway
oil low,No oil pressure,Spindle inverter fault"
addf oillow servo-thread
addf oilpressure servo-thread
addf inverterfail servo-thread

setp oillow.edge 0 #this pin should be active low
net no-oil classicladder.0.out-21 oillow.trigger
net no-pressure classicladder.0.out-22 oilpressure.trigger
net no-inverter classicladder.0.out-23 inverterfail.trigger

And the moment any pin goes active → the matching message pops up on screen. ✨ like magic but it's just HAL ✨
