Goodii Language Specification

Note: Project is unfinished. Version 1.0 includes only possibility to:

• declare variables (e.g intii a;)
• assignment of intii and dublii values, (intii a = 5; dublii b = 5.0;)
• arithmetic: multiplication, substraction, addition, division (intii a = 5 + 5; intii b = 5 + 10; intii c = a + b)
• compilation errors when intii and dublii are used in a single statement (e.g intii a = 5; dublii b = 10.0; intii c = a + b; // compilation error!
• printing value of intii and dublii to the otput stream (e.g printii(a); printii(5); printi(55.0);
• reading value from input stream (e.g intii a; ridi(a);)
• if statement - without else (e.g intii a = 5; intii b = 10; ifi(a => b) { //some action };

(the whole specification is possibly for the future versions)

Goodii Input/Output

name	description
Printi (value)	Printing identifier value to output stream.
Printi (5)	Printing intii value to output stream.
Printi (55.0)	Printing dublii value to output stream.
Ridi (value)	Reading intii value from input stream and assign it to value identifier of type *intii.

Others

• Intii values and Dublii values cannot be used in a single expression (e.g we cannot assign intii a = 5 + 5.0; as 5.0 is represented as Dublii)
