fd1481fa43 Minor VM refactor + GC bug fix
The VM now respects metamethods from proto objects connected to tables. Also the CState is frozen while being instantiated.

2864c7be53 Minor refactoring, added OP_GETMETHOD
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.

e995bb75fb added tonumber() and tostring() to base lib 2021-01-13 14:13:55 -06:00

ab86e19cfe Added ':' invoke operator
You're now forced to use ':' when calling a method on an object. Some of Lua's ideas really are just better in practice /shrug

c510c9aebf Minor table refactor, added cosmoV_compileString and loadstring() to baselib
cosmoV_compileString is recommended since it'll push the result (<error> or <closure>) onto the stack.

also, fixed some GC-related bugs, so yay!

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.

860f30f201 removed printStack() from cosmoB_pcall() 2021-01-05 22:46:04 -06:00
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.
