* refactor: move primitive errors; refactor primtiveInfo This commit is the first in what will hopefully be a series of helpful primitive refactors. To start, we: - Move some inline `evalError` strings into a `PrimitiveError` module, (similar to the `TypeError`/`Types` module relationship - Add `Reifiable` instances for String and Int types to take these types to their XObj representation. - Add info utility functions for converting Info data to an XObj - Refactor the `info` primitive: - Use monadic combinators + `maybe` instead of nested cases. - Use helper lookup functions that take a *context*--nearly *all* lookup calls currently extract some env, typically without doing anything to it, to pass it to lookup. This is a sign the boundary is incorrect and lookups should take the context instead--this will allow us to eliminate a ton of local `globalEnv`, `typeEnv`, etc. bindings. - Don't print hidden bindings - Indent printed meta information. - Color bindings blue * chore: format code * refactor: improve names for lookups that take a context * feat: print hidden binders when calling info Someone calling info might be interested in hidden binders as well, for debugging purposes, etc. To enable this, we provide a version of show for binders that prints hidden binders. I've also made the printing of meta values in info more generic. |

Carp
WARNING! This is a research project and a lot of information here might become outdated and misleading without any explanation. Don't use it for anything important just yet!
Version 0.4 of the language is out!
About
Carp is a programming language designed to work well for interactive and performance sensitive use cases like games, sound synthesis and visualizations.
The key features of Carp are the following:
- Automatic and deterministic memory management (no garbage collector or VM)
- Inferred static types for great speed and reliability
- Ownership tracking enables a functional programming style while still using mutation of cache-friendly data structures under the hood
- No hidden performance penalties – allocation and copying are explicit
- Straightforward integration with existing C code
- Lisp macros, compile time scripting and a helpful REPL

A Very Small Example
(load-and-use SDL)
(defn tick [state]
(+ state 10))
(defn draw [app rend state]
(bg rend &(rgb (/ @state 2) (/ @state 3) (/ @state 4))))
(defn main []
(let [app (SDLApp.create "The Minimalistic Color Generator" 400 300)
state 0]
(SDLApp.run-with-callbacks &app SDLApp.quit-on-esc tick draw state)))
For instructions on how to run Carp code, see this document.
