qalc

A language to quickly build multipurpose tools for calculations.

Purpose

Effectively programming TI84s is very difficult. Writing good programs requires managing Lbls for several different menu items. Additionally, the TI84 makes writing out programs and debugging incredibly difficult.

To fix this, I made a half-baked attempt at writing a language that simplifies some of these problems. The reason the language is not nearly is good as it should be is time. I made this so I can work on my homework more effectively, not so I can spend all day hacking on the compiler.

Usage

There are very few commands, but they are very simple.

Command	Usage	Example
menu NAME { ... }	Creates a menu of items of which you can choose from. Each item will run a different segment of code in response.	menu "MENU" { "ITEM1" { print "You chose 1"; } "ITEM2" { print "You chose 2"; } }
print ITEM...	Prints something to the screen.	print 1 "Hello world";
input VAR	Stores user input to a variable.	input i;
for VAR in FIRST..LAST { ... }	Creates a for loop.	for i in 0..10 { print i; }
while ITEM { ... }	Creates a while loop.	while true { print "hi"; }
if ITEM { ... }	Creates an if statement with no else clause.	a = true; if a { print "a is true"; }
if ITEM { ... } else { ... }	Creates an if statement with an else clause.	a = true; if a { print "a is true"; } else { print "a is false"; }
clear	Clears the screen.	clear;
stop	Exits the program.	stop;
pause	Pauses the program and waits for the user to press ENTER.	pause;
VAR = ITEM	Stores ITEM into VAR.	a = 5;
# COMMENT	Adds annotations to code.	# Im a comment!
