Dust programming language

Сompiled, simple imperative programming language created for the purpose of education with support for basic variable declarations, assignments, expressions, printing, program termination like exit() in C language and logical operators. The compiler is made using LLVM. When building the compiler, i didn`t implement AST, as many people do. All tests were performed on Ubuntu Linux.

Was done

• Variables semantic
• Mut statement
• Assign statement
• Exit statement
• Arithmetic operations with precedence
• Wrint line statement
• Const variables
• String variables
• Bool variables
• Float variables
• Logical operators
• If statement
• Loop statement
• Math functions
• Etc...

Getting started

Build it yourself

Dependencies: LLVM-DEV, LLVM, C++20, GTest (not necessary)

git clone https://github.com/wandvvs/dust-lang
cd dust-lang/
cd build/
cmake ..
make

Example

use io;

const a = 10 + 2;
mut b = (5 * 2) + 2;

const aEqualB = ? a == b;
writeln(aEqualB);

const PI = 3.14;
const EI = 1.57;

const piLessThanEI = ? PI < EI;
writeln(piLessThanEI);

mut test = ? PI == EI * 2;
writeln(test);

test = "froom boolean to str";
writeln(test);

test = ? 1.57 * 2 == PI;
writeln(test);

./dust-lang <input.dust>
./out

Output:

true
false
true
froom boolean to str
true
