Basics

ACPUL 1.01

ACPUL programming language​

Key features

  • formulas
  • everything is float
  • EOL ; is must

Formula​

ACPUL operates formulas.

Formula header defines formula

### my.formula

Multiple formulas example

### my.formula1

rnd(u0);

### my.formula2

sin(x);

Why ;?​

; is important! in ACPUL 1.01

0;
a 0;
a b;
a=0;
a+=1;
if (a) {...};
while (a) {...};

Ident​

ACPUL defined for any screen size, so 1 ident is prefered

1 ident (default)

2 ident (due to editors)

Name​

Define name as number, function or object

a 1;        # a is 1 (number)

fn rnd(u0); # fn is function (expression), returns random number 0..1

fn {        # the same
 rnd(u0);   # returns random number 0..1
};

color {     # color is an object with r,g,b values
 r 0;
 g 0;
 b 0;
};

Follow '_'​

a {
 b 0;
};
a {
 _; # follow previous a
 c 1;
};
a.b; # 0;
a.c; # 1;
a 0;
b a; # b link to a

Import @file​

Import here

_ @sys.node; # use sys.node

Import as object

module @my.module; # module is my.module
module.run;

Variable​

The ACPUL programming language has 3 variable declaration operators

Define new variable. Execution independent

a 0; # a is 0

Set new variable

a=0; #

Update existing variable

b 0; # b is 0
b:=1; # b is 1

Operator if​

if (expr) {
 ...
};

Note:

No else operator in ACPUL 1.01

Operator while​

while (expr) {
 ...
};
i = 0;
while (i < 5) {
 i+=1;
};

Note:

Infinitie loops will be break automaticly

Reliability​

No recursions​

No recursive calls

Maximum call 256 for file import

No more infinitie​

Infinitie loops will be break automaticly

No memory overflow​

Malcisous formulas will be terminated automaticly
