Behenlang is a toy programming langauge inspired from Bhailang.

Geting Started

Prerequisites

You need llvmlite and sly modules to run the project.

• llvmlite

  pip install llvmlite

• sly

  pip install sly

Usage

Compiling the code

Extention for behenlang is .behen , to compile .behen files use

python run.py <filename.behen>

This will generate a .ll intermediate code file in the same folder where code is present and output the result too.

Documentation:

General

kaam is used to define a function. One must define main function in the project. Example :

kaam int main() {
    # code goes here
    behen bhejo 0     #similar to return
}

behen or didi is used to initialize any statement.

Print

behen bolo() or didi bolo() is used to print the strings :

kaam int main() {

    didi bolo("Namste Duniya \n")
    behen bolo("Hello World")       #this is comment

    behen bhejo 0
}

Defining Variables

kaam int main() {

    behen x=5
    behen y=9.0
    
    behen bhejo 0
}

Conditional Statements

kaam int main() {

    behen num1 = 18
    behen rem = num1 % 2
    behen agar rem == 0{
        behen bolo('Even')
    } 
    warna{
        behen bolo('Odd')
    }

    behen bhejo 0
}

Iterations

kaam int main(){
    behen i = 0
    jabtak i < 10
    {
        didi bolo('Hello ')
        didi i = i+1
    }
   didi bhejo 0
    }

Calling Functions

kaam int hello() {
    behen bolo("Ye hai hello function\n")
    behen bhejo 0
}

kaam int main(){
    hello()
    behen bolo("Ye hai main fun")
    behen bhejo 0
}
