haste-lang

How to try haste?

1. You got to clone this repo and navigate to where you cloned it

git clone https://github.com/mega-haste/haste-lang
cd haste-lang

2. You should be already installed premake in order to run this command

premake5 gmake --cc=clang

NOTE: Since i switched to premake testing the scanner isn't avialable yet cuz I'm too lazy to do that

3. Now go to build/ folder and run make

cd build/
make

4. Now create a main.haste file inside build/

touch main.haste

5. Edite main.haste file you created earlier and add these folowing lines

func main() {
    let a: int = 50; # Expected warning
}

Language progress

• Scanner
• Parser
  • Expressions
    • Primaries
    • Math (+, -, *, **, /, %)
    • Comparition (==, !=, <, >, >=, =<)
    • Logical (not, and, or)
    • Bitewise (&, |, ~, <<, >>)
    • inline if (if .. then .. else ..)
    • as (type casting expr as Type)
    • call expression
    • member access
    • Subscript (expr[v])
    • Scope resolusion
    • Tuple
    • assignment
    • referencing and dereferencing (&expr and *expr)
  • Types
    • Built-in types (int, uint, float, string, void, bool)
    • Slices (T[int], T[])
    • Tuple ((T, R, Y, X, ...))
    • Generics aka. templates in c++ (T<Args>)
  • Statements
    • returns
    • if
    • let
    • functions (needs to add generecs to it)
  • Semantic Analysis
    • Added basic types (arrays, functions, native types eg. bool, int, uint, char, string)
    • Working immutability
    • Function calls
    • Subscripting
    • Member accessing
    • Scope resolusion
    • Warnings (unused variables, unused mut)
    • tuples and multi dimentional arrays
    • Custom Defined types
    • Generics
    • Secret 🤫

Hello World

func main() {
    # no working hello world yet :(
    # but we got variables :D
    let x = 5;
    let mut y = 9;
    y += 1;
}

# My desired hello world
func main() {
    @println("Hello World");
}

My goals

• Nicer Error messages
• Adding a good type-checking & Semantic analysis
• Traspiling haste to c (I'm planing on using llvm to compile haste directly to machine code)

Something

I dropped the idea of tags, sorry Amir
