2014-03-08Implement ROMable modules. Add math module.Damien George
mp_module_obj_t can now be put in ROM. Configuration of float type is now similar to longint: can now choose none, float or double as the implementation. math module has basic math functions. For STM port, these are not yet implemented (they are just stub functions).
2014-02-15Implement proper exception type hierarchy.Damien George
Each built-in exception is now a type, with base type BaseException. C exceptions are created by passing a pointer to the exception type to make an instance of. When raising an exception from the VM, an instance is created automatically if an exception type is raised (as opposed to an exception instance). Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper. Handling of parse error changed to match new exceptions. mp_const_type renamed to mp_type_type for consistency.
2014-02-15Change mp_obj_type_t.name from const char * to qstr.Damien George
Ultimately all static strings should be qstr. This entry in the type structure is only used for printing error messages (to tell the type of the bad argument), and printing objects that don't supply a .print method.
2014-02-11mp_obj_equal(): Instead of assert(), throw NotImplementedError.Paul Sokolovsky
With a nice traceback, helps debugging much better.
2014-02-08unix microsocket: Add dummy makefile() method.Paul Sokolovsky
Unlike CPython socket, microsocket object already implements stream protocol (read/write methods), so makefile() just returns object itself. TODO: this doesn't take care of arguments CPython's makefile() may accept.
2014-02-01py: Tidy up BINARY_OPs; negation done by special NOT bytecode.Damien George
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new special NOT bytecode.
2014-01-30py: Improve __bool__ and __len__ dispatch; add slots for them.Damien George
2014-01-30Implement __bool__ and __len__ via unary_op virtual method for all types.Paul Sokolovsky
__bool__() and __len__() are just the same as __neg__() or __invert__(), and require efficient dispatching implementation (not requiring search/lookup). type->unary_op() is just the right choice for this short of adding standalone virtual method(s) to already big mp_obj_type_t structure.
2014-01-29py: Add compile option to enable/disable source line numbers.Damien George
2014-01-23py: Simpler implementation of mp_obj_callable.Damien George
2014-01-23mp_obj_is_callable(): Only object types can be callable.Paul Sokolovsky
Fixes segfault on callable("string").
2014-01-22Second stage of qstr revamp: uPy str object can be qstr or not.Damien George
2014-01-22py: Remove implicit conversion of float to int in mp_obj_get_int().Damien George
Addresses Issue #199.
2014-01-21Add len() support for arrays.Paul Sokolovsky

2014-01-21Revamp qstrs: they now include length and hash.Damien George
Can now have null bytes in strings. Can define ROM qstrs per port using qstrdefsport.h
2014-01-20mp_obj_get_type_str(): Handle MP_OBJ_QSTR.Paul Sokolovsky
2014-01-20mp_identity(): Add generic identity function.Paul Sokolovsky
Useful as getiter method for objects which are their own iterators, etc.
2014-01-20mp_obj_get_qstr(): Handle MP_OBJ_QSTR.Paul Sokolovsky
2014-01-20Properly print MP_OBJ_QSTR objects.Paul Sokolovsky
2014-01-19py: Add full traceback to exception printing.Damien George
2014-01-18Merge branch 'master' of github.com:dpgeorge/micropythonDamien George
2014-01-18int: Add value accessors: mp_obj_int_get() & mp_obj_int_get_checked().Paul Sokolovsky
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.
2014-01-18Make VM stack grow upwards, and so no reversed args arrays.Damien George
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.
2014-01-15type->print(): Distinguish str() and repr() variety by passing extra param.Paul Sokolovsky
2014-01-13mp_obj_equal(): Compare small and long ints properly.Paul Sokolovsky
By dispatching to long int methods.
2014-01-12mp_obj_equal(): For non-trivial types, call out to type's special method.Paul Sokolovsky
2014-01-11py: Implement staticmethod and classmethod (internally).Damien George
Still need to make built-ins by these names, and write tests.
2014-01-10Merge pull request #131 from chipaca/dict_fromkeysDamien George
Added dict.fromkeys.
2014-01-11mp_obj_equal(): Print which types' equality not implemented before assert().Paul Sokolovsky
2014-01-10Added dict.fromkeys. Are we done with dict and #99 yet? I do think we are.John R. Lenton
2014-01-08py: add variable argument exception constructor function.Damien George
Addresses issue #104.
2014-01-08py: Stuff qstr in object pointer; keys for mp_map_t are now always mp_obj_t.Damien George
2014-01-08py: Improve __build_class__.Damien George
2014-01-04Convert Python types to proper Python type hierarchy.Damien George
Now much more inline with how CPython does types.
2014-01-04Split qstr into pools, and put initial pool in ROM.Damien George
Qstr's are now split into a linked-list of qstr pools. This has 2 benefits: the first pool can be in ROM (huge benefit, since we no longer use RAM for the core qstrs), and subsequent pools use m_new for the next pool instead of m_renew (thus avoiding a huge single table for all the qstrs). Still would be better to use a hash table, but this scheme takes us part of the way (eventually convert the pools to hash tables). Also fixed bug with import. Also improved the way the module code is referenced (not magic number 1 anymore).
2014-01-01py: add int() and float() built-ins, partially implemented.Damien George
2013-12-21Change object representation from 1 big union to individual structs.Damien
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).
