0d344f65df renamed cosmoV_pushObj->cosmoV_pushRef & cosmoV_newObj->cosmoV_newRef 2021-02-07 14:05:53 -06:00
cd6744ab65 Minor refactor, added vm.* library

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.

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.

1351ff63b1 Added CObj->proto support, state->protoObjects defines default protos for each COBJ type
a lot of refactoring in the VM

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.

31a852a127 Added cosmoV_pushFString(), and cosmoO_pushVFString().
cosmoV_error now pushes the error string onto the stack, as well as uses cosmoO_VFString to format strings.
cosmoV_concat is now entirely self contained, and is now stack based. Push the CValues you want to concat into strings onto the stack and call cosmoV_concat with the # of values you pushed.

48ceca1834 multiple return value support added to VM 2020-12-12 21:53:12 -06:00
181ef8a18c Added dictionaries {}
Objects are now separate from {} dictionaries

the . operator now only indexes fields on objects, the [] operator can only be used on objects if the __index or __newindex functions are defined

Additionally 4 new instructions have been added to the VM: OP_NEWDICT, OP_INDEX, OP_INCINDEX, and OP_NEWINDEX.

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

The Lexer & Parser was extended to add the TOKEN_COLON ':' token.
