Cosmo - Kosmo

(Kevins)Osmo get it.. ha..

Cosmo is a statically-typed interpreted programming language written in pure Crystal.
We have an extension for VS code (source), however it currently only features syntax highlighting and code snippets.

Installation

git clone https://github.com/KevinAlavik/cosmo
cd cosmo
sudo make

Whats different in this fork?

Nothing much just some extra things!

Things I Gotta Do

Features

Grammar
- Regexes
- Endless (and beginless?) range literals
- Postfix every loop (e.x. x < 1 for every int x in vec)
- typeof
- Multiple assignment/declaration with spreads (e.x. int x, y = *[1, 2])
- := operator (this will include making = binary expressions a statement [this is gonna be weird to implement lmao])
- Enums
- Decorators
- Interfaces
- Namespaces
- Classes
  - single inheritance
  - mixins
  - static/protected members
- Rewrite type system
  - bound expressions (!!)
  - an actual type pass
  - generics
  - type inference
  - casting union types
  - implicit conversions
  - intersection types
Other
- Extend HTTP library
- + operator for vectors, same functionality as Vector->combine
- string and char to hex conversions (e.x. <uint>'f' == 15)
- Some form of multithreading
- Intrinsic methods for all datatypes (inherit from a base type)
- REPL supports multiline source

Fixes

Performance boosts lol
Import stack traces
Properly log errors from intrinsics
Segfaults
- passing $? (pretty sure this is just like everything to do with classes)
- <float[]>[1,2,3]
Class instance variables available outside of $
Throw if same module was imported twice
["a.b.c"].first.split('.') tries to access ["a.b.c"].first instead of ["a.b.c"].first() because of the split call with parentheses (bug)

Tests

Chained method calls with optional parentheses (e.x. ["a.b.c"].first.split('.').first == "a")
Expectation of errors in parser spec (e.x. () throws Invalid syntax ')': Expected an expression)

Refactorings

(empty)

TODO: http server routing stuff
