moks

An interpreted language that I am writing @recursecenter.

Sample program in moks:

let fib n = {
  (n < 2)? {
    1
  } : {
    fib (n-1) + fib (n-2)
  }
}
 
print (fib 10) // should be 89
print (fib 20) // should be 10946
 
print (map (\x { x + 1; }) [1 2 3 4]) // should be [2 3 4 5]
 

Either semicolons OR newlines terminate lines. Do not use both or my parser will throw a cryptic error.

Play with it

Note: moks needs iojs currently since it uses features from v8 that node doesn't have yet

npm i -g moks

This should install the moks interpreter globally.

You can then run moks <path to .mok file> or moks -e "<expressions in valid moks syntax>".

For e.g.,:

moks ./fib.mok
moks -e "let add x y = {  x + y; }; print (add 2 3);"

Future plans

Things/features I plan to experiment with in the future:

  • FFI to Javascript
  • support arrays & maps
  • module system
  • lamda support
  • add nil
  • repl
  • error handling
  • marking side effects syntactically
  • runtime optimizations
  • stack based runtime (currently uses the underlying js runtime stack)
  • macros
  • simple type system
  • pausable and rewindable code editing

Also, if you use emacs, here's a simple emacs major mode for moks.
