Adding Function (Funda) for #170

[thecodacus]

This PR closes issue #154 and Based on #170, this will be the first stage to make it more like a real programming language.

added Functional Programming features,

you can now create funda (functions) to make your code modularized, and not repeat yourself

example

hi bhai
apna funda test(c){
  bol bhai c;
  rakh le bhai "return bhi "+c;
}
bol bhai test("kam kiya bhai");
bye bhai

output

kam kiya bhai
return bhi kam kiya bhai

Great work! will check.

[ankitchouhan1020]

hi bhai

apna funda Counter() { 
  bhai ye hai count = 1;
  
  apan funda increment() {
    count += 1;
    rakh le bhai count;
  }
  
  rakh le bhai increment;
}

bhai ye hai tick = Counter();
bol bhai tick();

bye bhai

Does it support closures ? Not working in preview.

Great work @thecodacus.

I will look into this. I was thinking to have duck typing in the functions. But this will also work

[tbhaxor]

Shouldnt we have it outside hi bhai? Like other languages? Hi bhai is the execution entry point

Shouldnt we have it outside hi bhai? Like other languages? Hi bhai is the execution entry point

with the current setup, anything that is outside "hi bhai" is discarded, I am working on "include" features then will try to change this in a new PR

[shankarkrupa]

@ankitchouhan1020 @aniketsingh0104 or @ristri - could one of you review and approve the PR to be merged with the develop branch? This is such a cool and important feature. Eager to see this spreading against after playing around with this a bit in the netlify preview playground.

[aniketsingh0104]

To be reviewed this week.

[aniketsingh0104]

Complete Review would be only possible after the test cases are included.

Critical: I see test cases are missing from this change specially from Parser. We won't review any PRs which do not contain proper test cases. Please write proper test cases covering positive and negative scenarios for both PARSER and INTERPRETER.

test cases added

[thecodacus]

took me a while to get the time and make the changes :) @aniketsingh0104 please check the changes
