Embeddable scripting language loosely based off of Lua

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. |

Cosmo
Cosmo is a portable scripting language loosely based off of Lua. Cosmo easily allows the user to extend the language through the use of Proto objects, which describe the behavior of Objects. For example the following is a simple Vector Proto which describes behavior for a Vector-like object.
proto Vector
function __init(self)
self.vector = {}
self.x = 0
end
function __index(self, key)
return self.vector[key]
end
function push(self, val)
self.vector[self.x++] = val
end
function pop(self)
return self.vector[--self.x]
end
end
var vector = Vector()
for (var i = 0; i < 4; i++) do
vector.push(i)
end
for (var i = 0; i < 4; i++) do
print(vector.pop() .. " : " .. vector[i])
end

C API
The Cosmo C API is currently undocumented, however as soon as development has reached a stable state documentation on full language features and the C API will start.
