Monkey

Yet another monkey-lang interpreter. Based off of Thorsten Ball's Writing an interpreter in Go. See also :monkeylang.org.

About

Don't use this, it is simply a side-project. There are much better interpretations available. See monkeylang.org.

Seemingly like most adaptations, this repo builds upon Thorsten's canonical version in this case by adding:

• Addtional operators and operations
• Additional builtin functions
• A module system

Most of this could not have been achieved without additional help, in particular from referencing these implementations:

• prologic/monkey-lang
• bradford-hamilton/monkey-lang

Roadmap

Done

1. Additional operators and operations
   • modulus // 3 % 2 = 1
   • comments // single line comments only
   • boolean AND and OR // true && false || true
   • Array concatenation ([1,2] + [3] // [1,2,3])
2. Additional Builtins
   • String functions
     • split(string, delimiter) // Array
   • Array functions
     • join(array, delimiter) // String
   • Hash functions
     • keys(hash) // Array
     • values(hash) // Array
3. Add module system
   • uses absolute paths or paths relative to the importing file (or current working directory for interactive mode). I took this almost verbatim from prologic's version.
   • Note: importing executes the loaded module, so you should only import modules that don't have side-effects.
4. Create a standard library of monkey functions implemented in monkey (requires a working module system)
   • Array functions (map, filter, reduce)

ToDo

1. Add more builtins and operations - ONGOING
   • Dictionary concatenation?
   • file I/O e.g let f = open(filePath, ["r"|"w"|"a"])
   • Variable destructuring - this would be a great way to improve import syntax i.e. let {map, filter, reduce} = import("./stdlib/arrays.mo");
   • Build upon our new standard library
2. Loops?
3. Sets?
4. Create a TCP Server
5. Create a Web Server
6. and - if no one else has done this by the time we get here - get some syntax highlighting going
7. Port to Python :-)
8. Port to Java :-(
