This is official repository for bhai-lang.

Bhai lang is a toy programming language written in Typescript.

npm i -g bhailang 

hi bhai bol bhai "Hello bhai"; bye bhai 

bhailang test.bhai 

hello bhai 

hi bhai is the entrypoint for the program and all program must end with bye bhai. Anything outside of it will be ignored.

 This will be ignored hi bhai // Write code here bye bhai This too 

Variables can be declared using bhai ye hai.

 hi bhai bhai ye hai a = 10; bhai ye hai b = "two"; bhai ye hai c = 15; a = a + 1; b = 21; c *= 2; bye bhai 

Numbers and strings are like other languages. Null values can be denoted using nalla. sahi and galat are the boolean values.

 hi bhai bhai ye hai a = 10; bhai ye hai b = 10 + (15*20); bhai ye hai c = "two"; bhai ye hai d = 'ok'; bhai ye hai e = nalla; bhai ye hai f = sahi; bhai ye hai g = galat; bye bhai 

Use bol bhai to print anything to console.

 hi bhai bol bhai "Hello World"; bhai ye hai a = 10; { bhai ye hai b = 20; bol bhai a + b; } bol bhai 5, 'ok', nalla , sahi , galat; bye bhai 

Bhailang supports if-else-if ladder construct , agar bhai block will execute if condition is sahi, otherwise one of the subsequently added nahi to bhai blocks will execute if their respective condition is sahi, and the warna bhai block will eventually execute if all of the above conditions are galat

 hi bhai   bhai ye hai a = 10;   agar bhai (a < 20) { bol bhai "a is less than 20"; } nahi to bhai ( a < 25 ) { bol bhai "a is less than 25"; } warna bhai { bol bhai "a is greater than or equal to 25"; } bye bhai 

Statements inside jab tak bhai blocks are executed as long as a specified condition evaluates to sahi. If the condition becomes galat, statement within the loop stops executing and control passes to the statement following the loop. Use bas kar bhai to break the loop and agla dekh bhai to continue within loop.

 hi bhai   bhai ye hai a = 0;   jab tak bhai (a < 10) {    a += 1;    agar bhai (a == 5) {     bol bhai "andar se bol bhai ", a;     agla dekh bhai;    }    agar bhai (a == 6) {     bas kar bhai;    }    bol bhai a;   }   bol bhai "done"; bye bhai
