Hp Prime

Write, review and deploy programs, apps and interfaces for HP Prime calculators (G1/G2), in PPL or MicroPython. Use whenever .hpprgm, .hpappdir, .hpapp or .hpappprgm files appear, or PPL code (EXPORT/BEGIN/END, LOCAL, TEXTOUT_P, INPUT, CHOOSE, DRAWMENU, GETKEY), or Prime Python (import hpprime, hpprime.eval, fillrect), or the HP Connectivity Kit or Virtual Calculator, or when data, calculation or an interface has to go onto an HP Prime.

HP Prime

PPL is badly documented and its compiler only says syntax error with a line number. This kit removes the two things that waste the most time: guessing the syntax and the paste-and-compile ritual in the Connectivity Kit.

Start here

Read AGENTS.md. It is the operating contract for this repository: what to read before writing PPL, the two gates every program goes through, what you must not claim, and what only the human can do. It is short, and everything below assumes it.

Then read docs/reference/ppl.md before writing a line -- especially §2, four hypotheses that look reasonable and are false.

The loop, in three commands

hpprime lint FILE.txt                  # what the compiler will not explain
hpprime run  FILE.txt --call "F(2)"    # run the real file, here, no calculator
hpprime write FILE.txt -o PROG.hpprgm  # build the binary

Onto the emulator you can install it yourself:

hpprime install PROG.hpprgm --restart  # copies, and reopens the emulator
hpprime pull PROG --diff FILE.txt      # and this is what is really on there

To find out where the PC interpreter and the real one disagree:

hpprime compare lib.txt --call "F(2)"  # the human types HPKCMP once, and
                                       # closes the emulator; the numbers
                                       # come back as a file

Onto a physical calculator you cannot: that is the human dragging the file onto the calculator in the Connectivity Kit window, and copying into the CK's mirror folder does not work -- docs/reference/deploy.md.

hpprime doctor checks the machine, hpprime new NAME writes a starter that already runs, hpprime build makes an app, hpprime verify checks one. Every command is in docs/tools.md.

If the user has never programmed a Prime

Send them to docs/start/01-setup.md before anything else. It is a six-step path from an empty folder to something running on the calculator, and step 6 is about working with you.

Installing this skill

git clone https://github.com/JordiRigau/hp-prime-kit ~/.claude/skills/hp-prime

The repository is the skill: SKILL.md sits at its root, so any session that touches .hpprgm files or PPL code has the measured rules in front of it instead of improvising syntax.
