Paul Sokolovsky d720ab5236 Implement modules as singletons Python semantics.
In Python, importing module several times returns same underlying module
object. This also fixes import statement handling for builtin modules.

There're still issues:
1. CPython exposes set of loaded modules as sys.modules, we may want to
do that either.
2. Builtin modules are implicitly imported, which is not really correct.
We should separate registering a (builtin) module and importing a module.
CPython keeps builtin module names in sys.builtin_module_names .

Damien George a11ceca807 Change int to uint for n_args in function with variable arguments. 2014-01-19 16:02:09 +00:00
Damien George 136b149e41 py: Add full traceback to exception printing. 2014-01-19 12:38:49 +00:00
Damien George cbd2f7482c py: Add module/function/class name to exceptions.
Exceptions know source file, line and block name.

Also tidy up some debug printing functions and provide a global
flag to enable/disable them.

Damien George 6b21538e91 Merge pull request #192 from pfalcon/arrays
Add skeleton implementation of array.array and bytearray.

Damien George 08335004cf Add source file name and line number to error messages.
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.

Paul Sokolovsky 427905cedd Add skeleton implementation of array.array and bytearray.
So far, only storage, initialization, repr() and buffer protocol is
implemented - alredy suitable for passing binary data around.

Paul Sokolovsky d26b379eec int: Add value accessors: mp_obj_int_get() & mp_obj_int_get_checked().
mp_obj_int_get() can be used when just full resolution of C machine_int_t
is required (returns truncated value of long int). mp_obj_int_get_checked()
will throw exception if Python int value not representable in machine_int_t.

Damien George 20006dbba9 Make VM stack grow upwards, and so no reversed args arrays.
Change state layout in VM so the stack starts at state[0] and grows
upwards.  Locals are at the top end of the state and number downwards.
This cleans up a lot of the interface connecting the VM to C: now all
functions that take an array of Micro Python objects are in order (ie no
longer in reverse).

Also clean up C API with keyword arguments (call_n and call_n_kw
replaced with single call method that takes keyword arguments).  And now
make_new takes keyword arguments.

emitnative.c has not yet been changed to comply with the new order of
stack layout.

Paul Sokolovsky 757ac81a69 Add proper checks for fits-in-small-int. Make it reusable.
We likely should make mp_obj_new_int() inline, and rely on its
encapsulated check rather than inline checks everywhere explicitly.

Also, parser for big small int values is still broken.

Damien George 062478e66d Improved type/class/instance code; mp_obj_type_t now has load_attr, store_attr.
Creating of classes (types) and instances is much more like CPython now.
You can use "type('name', (), {...})" to create classes.

Damien George 38a2da68c2 py: Stuff qstr in object pointer; keys for mp_map_t are now always mp_obj_t. 2014-01-08 17:33:12 +00:00
Paul Sokolovsky 5b15daf6d1 Add support for stream and buffer protocols.
Stream protocol is abstraction of serial I/O. Buffer protocol is
abstraction of random-access I/O. These protocols are defined down
to C level, to allow generic, while still efficient algorithms
to be coded in C (like, buffered transfer between 2 stream objects,
saving/loading of buffer object to/from stream, etc). (Note that CPython
define buffer protocol on C level, but apparently not stream protocol).

John R. Lenton c06763a020 This implements a better (more python-conformant) list.sort.
It's not really about that, though; it's about me figuring out a sane
way forward for keyword-argument functions (and function
metadata). But it's useful as is, and shouldn't break any existing
code, so here you have it; I'm going to park it in my mind for a bit
while sorting out the rest of the dict branch.

Damien d99b05282d Change object representation from 1 big union to individual structs.
A big change.  Micro Python objects are allocated as individual structs
with the first element being a pointer to the type information (which
is itself an object).  This scheme follows CPython.  Much more flexible,
not necessarily slower, uses same heap memory, and can allocate objects
statically.

Also change name prefix, from py_ to mp_ (mp for Micro Python).
