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
- currently only enabled on supported platforms (GNU C Compiler + Clang)
- when enabled, sped up examples/fibtest.cosmo by about 20% (avg of 11.179s prior and 8.799 after)
NOTE: malicious dumps can trivially cause crashes now by having junk function chunks
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
- cosmoV_registerProtoObject now walks the object list and updates the proto's for objects of the objType which have a NULL proto.
- misc. comment changes in cvm.h as well.
also changed print() to print raw primitives instead of generating a <string> needlessly. helped performance immensely in scripts like `examples/increment.cosmo`
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.
