LOGO/TURTLE/TORTUGA MODE on HP Prime Graphing Calculator
Hello

TEXAS INSTRUMENTS CALCULATORS TEAM is already publishing its graphic library =0
https://tiplanet.org/forum/viewtopic.php?f=41&t=23794

I think the greatest success of the introduction of a child or young person in the world of computational thinking is the simple graphic manipulation, like the logo/turtle, since it gives "life" to the output or response of an algorithm, instead of just displaying "boring" text.
I think it would be a good complement to HPPRIME to incorporate the LOGO mode app, so children can "paint" drawings with simple instructions

The Numworks calculator has already taken the first step
NumWorks https://github.com/numworks/epsilon/pull/748

PHP Code:
from turtle import *  def spiral(N_iteration):  N_iteration *= 25  for i in range(N_iteration):  # Change pen color  gray=255-(i*255/N_iteration)  pencolor(int(gray),int(gray*0.75),int(gray*0.25))  # Draw a segment of the spiral  forward(i*0.1)  left(10

PHP Code:
from turtle import *  def koch(N_iteration):  # Save pencil size and set it to 1  prevSize = pensize()  pensize(1)  # Define inner function for recursion  def _koch(n, l):  if n == 1:  forward(l)  else:  _koch(n-1,l/3)  left(60)  _koch(n-1,l/3)  right(120)  _koch(n-1,l/3)  left(60)  _koch(n-1,l/3)  # Call inner function  _koch(N_iteration,140)  # Restore pencil size  pensize(prevSize)

Tourtle frn info by Thomas Rey Source http://casedesmaths.net/images/pour_tous/xcas.pdf

Tortue Pour ceux qui ne connaissent pas, la tortue graphique faisait partie du langage de programmation Logo créé à la ﬁn des années 1960. Il s’agit en fait d’une « pointe de crayon » à qui on donne des ordres simples du style, avance de 10 unités, tourne de 45°à droite, change de couleur, . . .
Un module tortue est présent dans Xcas, on y accède en cliquent sur le menu Tortue. On obtient alors une fenêtre qui ressemble à la ﬁgure 6 (ci-jointe)

On peut écrire dans les lignes de saisie (à gauche de la ﬁgure) des instructions simples par exemple avance(30) ou tourne droite(60), . . . et la tortue exécute les ordres ; dans le même temps, les instructions sont recopiées dans la fenêtre de programmation (à droite).
On peut alors compléter par des boucles, des tests, comme dans le module Prog
L’ensemble des ordres possibles est accessible facilement sous la fenêtre graphique par un code à deux lettres av pour avance, re pour recule, . . . (la description s’aﬃche en « info-bulle » lorsqu’on survole le bouton à l’aide de la souris)

Par exemple, pour tracer un carré un programme possible est le suivant (à saisir à droite)

PHP Code:
pour k de 1 jusque 4 faire    avance(30);    tourne_droite(90); fpour;

On l’exécute en cliquant dans le menu Edit sur Exec all. Le carré se trace.
Autre exemple qui donne la ﬁgure 7 (ci-jointe).
PHP Code:
efface(); // Efface l’ écran    etapes :=36; // nombre de cercles "intérieurs"    p :=20; // longueur d’un côté du polygone à étapes côtés   h:=0.5*p/(tan(pi/etapes)); // rayon d’ un cercle intérieur    pas de cote 10; // pour centrer la fig    saute 60;  // idem   pour k de 1 jusque etapes faire // boucle   crayon irem(k ,5); // choix de la couleur du crayon   tourne gauche(360/etapes);// construction d’un côté   avance(p/2);  // suite   rond(h); // trace un cerclefpour ; // fin de boucle

RE: LOGO/TURTLE MODE on hpPrime

You do know this is "programmable" don't you?

There is more then just CAS functions. You don't seem to have discovered anything but that yet...

Ironically, Bernard Parisse's version of Xcas for the Casio FX CG-50 — Khicas — does include the turtle program.

RE: LOGO/TURTLE MODE on hpPrime
Indeed, it's gaining in popularity here in France as a transition between Scratch and Python(-like) programming. Xcas turtle commands would be straightforward to port on the Prime, but interface would require some work and it would probably be easier to implement independantly from the CAS, because in the Xcas implementation computation and drawing are done in 2 independant steps, which is much more complicated than required on a calculator (this limits the number of turtle instructions to 512 on the Casio Prizm because of the memory available).

Application, anyone?

RE: LOGO/TURTLE MODE on hpPrime
Original author here. Like Tim said, the HP Prime's programming language can easily support a user turtle implementation without needing the HP's team help to do it, as long as someone writes it. While I'm here, I'll point out that (if I recall correctly) the official MicroPython port of the Casio 90+E can't currently do graphics and neither does the not-yet-released external Python module for the TI-83 Premium CE.

For the NumWorks, I'm going for a native implementation because that calculator's Python environment is a bit cramped for a "nice" turtle. It should make a nice surprise for my nephew next time he plays with my calculator.

But Tim, what about adding turtle to the Prime, while reducing ram usage and getting more free flash space?

Also, a new CAS simple deep-learning algorithm could be used to predict if the user does not want these and remove it, freeing more space

It's up to the teacher/educational system.

what is the word "coficate"? (underlined)

Maybe it's from the same lexical root as "covfefe"

Everything old is new again.

I remember using LOGO in Elementary school (~1982) on a Apple ][ plus.

It would also mean every single one of the many commands would appear EVERYWHERE and be commands everywhere, no matter if relevant or not.

This would be a few days at work for an end user to create a much better version more fit for Prime. It is a good thing we created a PROGRAMMABLE graphing calculator, huh?

Remind me when they begin to catch up to everything else...

In the meantime, I look forward to seeing your published software you are working on.

RE: LOGO/TURTLE/TORTUGA MODE on HP Prime Graphing Calculator
It is known that the Python app may come in the future, if that happens I would very much like TURTLE to come with it, as long as it does not represent any inconvenience design.

For being an academic module seems to me a good alternative, especially because it allows the teacher to choose according to their pedagogical strategy, but it is true that it is not necessary to stack everything in HP Prime, there are devices that can be more compatible compared than a 320x240 calculator whose objective is to be a mini tool. The current simplicity and cleanliness of hp prime is highly appreciated so far.
