CPunch 8ac8085d20 syntax: 'var'->'let' 'function'->'func'

- 'func' looks visually appealing lol
- some minor refactoring done in cparse.c

You can use ':' without invoking. So you can grab a method binding to an object and later call it. Also some GC bugs were fixed.

A new preprocessor macro (VM_DEBUG) has been added. Defining this macro will print each instruction thats being executed in the VM, as
well as print each call.
 2021-01-16 15:40:58 -06:00

 2021-01-12 17:46:22 -06:00
CPunch c510c9aebf Minor table refactor, added cosmoV_compileString and loadstring() to baselib

 2021-01-10 14:38:53 -06:00
CPunch f0b666f623 better README 2021-01-08 23:53:02 -06:00

 2021-01-08 22:47:36 -06:00
CPunch 824c0e89b9 Dictionaries -> Tables 
Tables are going to become a more generic form of data storage. While objects will be "stateful", tables will remain static.

'{}' now refers to an object declaration, '[]' will be reserved for tables.

CPunch 860f30f201 removed printStack() from cosmoB_pcall() 2021-01-05 22:46:04 -06:00
CPunch eb2f50e456 Added CObjError, cosmoV_throw(), pcall(), and cosmoV_printError() 
Errors are now handled very differently, parser errors and VM errors are now treated the same.
When cosmoV_error is called, cosmoV_throw is also called, which formats the error object and sets the panic state.
state->error now points to the latest CObjError when state->panic is true. To get a nice formatted Objection message, use
cosmoV_printError() and pass the state->error. pcall() was added to the standard base library. When called, the first argument
passed is called with the subsequent arguments given. If the call completed successfully, `true`,`nil` is returned. However
when an error occurs during the call, `false`,`<error>` is returned. Simply print the `<error>` to retrieve the error string.
