SYSTM(9lua)

🌸 NAME 🌸

okay so bestie, this is the systm(9lua) page, and it's all about systm — the Lua binding that gives you access to general kernel functionality from Lua. Kernel vibes, but make it Lua. ✨

✨ SYNOPSIS ✨

local systm = require 'systm'

systm.print(msg)
systm.print_nolog(msg)
systm.uprint(msg)
systm.aprint_normal(msg)
systm.aprint_naive(msg)
systm.aprint_verbose(msg)
systm.aprint_debug(msg)
systm.aprint_error(msg)
count = systm.aprint_get_error_count()
systm.panic(msg)

💅 DESCRIPTION 💅

The systm Lua binding gives you access to general kernel functionality — like printing messages on the console. The systm.aprint functions are meant to be used during kernel autoconfiguration. Boot-time message main character energy, honestly. 🫶

• systm.print(msg) — sends msg to the console. 🖨️
• systm.print_nolog(msg) — literally identical to systm.print(), except it does not send msg to the system log. No log, no cap.
• systm.uprint(msg) — sends msg to the current process's controlling tty. 💻
• systm.aprint_normal(msg) — sends msg to the console unless AB_QUIET is set. Always sends to the log. ⭐
• systm.aprint_naive(msg) — sends msg to the console only if AB_QUIET is set. Never sends to the log. 🎀
• systm.aprint_verbose(msg) — sends msg to the console only if AB_VERBOSE is set. Always sends to the log. 🔥
• systm.aprint_debug(msg) — sends msg to the console and the log only if AB_DEBUG is set. 🐛
• systm.aprint_error(msg) — like systm.aprint_normal(), but it also keeps track of the number of times it's called. This lets a subsystem report how many errors happened during a quiet or silent initialization phase. 😭
• count = systm.aprint_get_error_count() — reports the number of errors and resets the counter to 0. Fresh start bestie.
• systm.panic(msg) — terminates the NetBSD system. The message msg is printed to the console and saved in the variable panicstr for later retrieval via core dump inspection. A newline character is added at the end automatically. 🚨 This is the big red button — it literally terminates NetBSD. 🚨

🦋 VARIABLES 🦋

Upon initialisation, the systm module sets the following variables with the values of the corresponding kernel variable:

• systm.copyright
• systm.cpu_model
• systm.machine
• systm.machine_arch
• systm.osrelease
• systm.ostype
• systm.kernel_ident
• systm.version
• systm.ncpu
