lets us do some cool things later. also the repl can print returned values. eg.
`return "hello world"` will print `<string> "hello world"` to the console
- 'var' has some weird scoping connotations with users of JS. better to change it to 'let', which will decide whether to make the variable a local or a global
- 'func' looks visually appealing lol
- some minor refactoring done in cparse.c
The object library includes:
- __proto getter and setter tables (might make an option to lock __proto in the future)
- ischild()
cosmoB_loadDebug was renamed to cosmoB_loadVM and now only loads the VM library
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.
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)]
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.
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.
- added OP_MOD, which performs a modulo operation on the 2 <number> values on the stack. Pops the 2 values and pushes the result.
- also added TOKEN_PERCENT to the lexer, and extended binary() in cparse.c to support it.
a LoopState was added to the CCompilerState struct which keeps track of breaks, start chunk index, and the start scope of the active loop.
Also, break.cosmo was added to the examples directory, 'continue' and 'break' work as expected.
__iter and __next are now reserved IStrings, OP_NEXT and OP_ITER have also been added. A new token (TOKEN_IN) has been added to the lexer. The parser now supports the for each loop (for i, ... in <object> do ... end).
savedPushed has been removed from the CCompilerState struct.
