✨ HALSHOW(1) ✨

okay bestie, welcome to halshow from The Enhanced Machine Controller — aka LinuxCNC 💖 this lil cutie shows off your HAL parameters, pins and signals and honestly? it's giving main character energy.

🌸 SYNOPSIS 🌸

halshow [Options] [watchfile]

that's it. that's the whole vibe. one optional watchfile and some options, we love a low-maintenance icon 🎀

💅 OPTIONS 💅

  • --help — shows the help. classic. iconic. never not useful 🫶
  • --fformat format_string_for_float — sets the format string for floats, so your decimals can serve exactly the way you want ✨
  • --iformat format_string_for_int — same deal but for ints, no cap 💜
  • --noprefs — says "don't use the preference file to save settings", so nothing gets remembered between sessions. a clean slate, a fresh start, we respect it 🦋

for the format situation, go look at https://www.tcl.tk/man/tcl8.6.11/TclCmd/format.html — it's the whole Tcl format lore, iykyk.

example, since a demo always eats:

  • "%.5f" displays a float with 5 digits right of the decimal point 🔥

🌈 DESCRIPTION 🌈

so halshow creates a GUI interface to view and interact with a running HAL session. yes, interact — you're not just looking, you're touching, you're manipulating, you're the moment 💅

and listen, it's documented in the PDF and HTML docs much more completely than is possible in a manpage, so if you want the full tea go here:

http://linuxcnc.org/docs/html/hal/halshow.html

👑 SEE ALSO 👑

and there's SO much more info about LinuxCNC and HAL available in the LinuxCNC and HAL User Manuals, found at /usr/share/doc/LinuxCNC/. go read them bestie, they're right there 📚✨
