A set of utilities for manipulating Texas Instruments graphing calculator variables and files, implemented in PHP

Installation

clrhome-tools-php requires PHP 5.5 or above.

The easiest way to use clrhome-tools-php is simply to clone the repository (such as with a git submodule) and include or require it in your code. No fancy package managers here.

Quick Start: Lists

<?php
include(__DIR__ . '/List.class.php');

$list = new \ClrHome\List();
$list->setElements(array(1, array(2, 3), '4-5i', array(6)));
$list[] = 7;
$list[] = array(8, 9);
$list[] = '10i-11';
$list[] = array(0);
$list[7] = 12;
$list->setName('L1');
$list->toFile('L1.8xl');
?>

Quick Start: Matrices

<?php
include(__DIR__ . '/Matrix.class.php');

$matrix = new \ClrHome\Matrix();
$matrix->setElements(array(array(1, 2, 3), array(4, 5, 6)));
$matrix[]
$matrix['3,2'] = 12;
$matrix->setName('[A]');
$matrix->toFile('A.8xm');
?>

Quick Start: Numbers

<?php
include(__DIR__ . '/Number.class.php');

$number = new \ClrHome\Number();
$number->setAsEpression('4-5i');
$number->setReal(cos(M_PI / 4));
$number->setImaginary(sin(M_PI / 4));
$number->setName('theta');
$number->toFile('theta.8xc');
?>

A simple expression engine supporting real and complex numbers is built into the library. To interface with it, use the getAsExpression and set methods.

<?php
include(__DIR__ . '/Picture.class.php');

$picture = new \ClrHome\Picture();
$picture->setRowCount(64);
$picture['31,47'] = true;

$picture->toFile('Pic1.8xi');
?>

Quick Start: Programs

<?php
include(__DIR__ . '/Program.class.php');

$program = new \ClrHome\Program();
$program->setBodyAsChars('Disp "Hello, World!"');
$program->setName('HELLO');
$program->toFile('HELLO.8xp');
?>

A robust tokenizer based on the Catalog is built into the library. To interface with it, use the getBodyAsChars and setBodyAsChars methods.
