CPunch c82a01c968 Minor refactoring, fixed 'or' and 'and' logical operators 2021-01-24 12:17:46 -06:00
CPunch 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.
 2021-01-23 17:16:45 -06:00
CPunch 0ad0df5fba Added '__tonumber' metamethod 2021-01-23 15:30:30 -06:00

CPunch 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.
 2021-01-16 15:40:58 -06:00

CPunch 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
 2021-01-12 17:46:22 -06:00
CPunch 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!
 2021-01-10 14:38:53 -06:00
CPunch f0b666f623 better README 2021-01-08 23:53:02 -06:00
CPunch 75b571c09a Added table support to the parser 
a new instruction, OP_NEWARRAY has been added. this instruction will create a table out of the uint16_t values on the stack, with incremental keys [0-(u16-1)]
 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.
 2021-01-08 14:37:36 -06:00

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.

 2020-12-24 00:41:00 -06:00

The syntax to create a dictionary is as follows { <key> : <value>, <otherkey> : <othervalue> } eg. { "hello" : "world", "foo" : 1337 }
