also a minor GC bug in cosmoO_newError was fixed.
i'm going to try to phase out cosmoM_freezeGC & friends
since that would cause hell with this new
error handling solution. the only thing still using it is the GC.
currently, scripts seem to run fine. however I'm a bit worried about stack related issues. maybe i'll need to reset state->top as well? but not entirely sure
This sets up room for the '__equal' metamethod to be added
- cosmoO_equals now requires the state to be passed
- cosmoV_equals now requires the state to be passed
- cosmoT_get now requires the state to be passed
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
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.
cosmoO_getObject and cosmoO_setObject were renamed to cosmoV_getRawObject and cosmoV_setRawObject respectively
`__init` is now required to be defined for a proto object to be instantiated.
other minor refactoring work done in src/cvm.c
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.
ISTRING_RESERVED was added to iStrings
call & callCFunction now use memmove instead of memcpy
Additionally, added cosmoO_setUserP, cosmoO_getUserP, cosmoO_setUserI and cosmoO_getUserI to the C API.
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.
