Damien George b11b85adaa py: Allow to pass buffer protocol flags to get_buffer helper funcs. 2014-04-18 22:59:24 +01:00
Damien George 57a4b4f178 py: Add typecode to buffer protocol.
When querying an object that supports the buffer protocol, that object
must now return a typecode (as per binary.[ch]).  This does not have to
be honoured by the caller, but can be useful for determining element
size.
2014-04-18 22:29:21 +01:00
Damien George ea8d06c39d py: Add MP_OBJ_STOP_ITERATION and make good use of it.
Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL.
This helps a lot in debugging and understanding of function API.

Damien George 729f7b42d6 py: Merge BINARY_OP_SUBSCR and store_subscr (w/ delete) into subscr.
mp_obj_t->subscr now does load/store/delete.

Damien George ee01411036 py: Add len(bytes). 2014-04-15 23:10:00 +01:00
Damien George 0e4ba25834 py: Fix SyntaxError exception: don't have a block name, so pass NULL. 2014-04-13 15:01:28 +01:00
Damien George 8a1cab952f py: Fix mp_get_buffer, and use it in more places.
Must use mp_obj_get_type to get the type of an object.  Can't assume
mp_obj_t is castable to mp_obj_base_t.

Paul Sokolovsky f130ca1f60 py: Make bytes type hashable. 2014-04-13 06:45:12 +03:00
Damien George a5c82a8187 py: Convert some macros to inline functions (in obj.h).
Also convert mp_obj_is_integer to an inline function.

Overall this decreased code size (at least on 32-bit x86 machine).
2014-04-11 11:16:53 +00:00
Damien George e22d76e73b py: Fix up object equality test.
It regressed a bit after implementing float/complex equality.  Now it
should be improved, and support more equality tests.
2014-04-11 10:52:06 +00:00
Damien George a9ddd6d9df py: Simplify and improve mp_get_index.
It has (again) a fast path for ints, and a simplified "slow" path for
everything else.

Also simplify the way str indexing is done (now matches tuple and list).

Damien George b8a053aeb1 py: Implement float and complex == and !=.
Addresses issue #462.

Damien George 686afc5c0a py: Check that sequence has 2 elements for dict iterable constructor. 2014-04-11 09:13:30 +01:00
Damien George b5fbd0ba87 py: Add mp_obj_is_integer; make mp_get_index check for long int.
mp_obj_is_integer should be used to check if an object is of integral
type.  It returns true for bool, small int and long int.

Paul Sokolovsky 3aa8ee7c9e py: Add mp_get_buffer(), mp_get_buffer_raise() convenience functions to API. 2014-04-09 01:07:37 +03:00
Damien George ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging.
This does not affect code size or performance when debugging turned off.

To address issue #420.

Paul Sokolovsky e99841be69 mp_obj_get_int(): Add warning against adding implicit float->int conversion. 2014-04-05 17:46:47 +03:00
Paul Sokolovsky 91cbe6033a py: Allow types to be hashable.
Quite natural to have d[int] = handle_int .

Damien George 36f0ee1a54 py: Remove mp_obj_less (use mp_binary_op(MP_BINARY_OP_LESS..) instead). 2014-04-04 15:07:17 +01:00
Damien George 8270e3853d py: More robust int conversion and overflow checking. 2014-04-03 11:00:54 +00:00
Damien George e09320adb5 py: Remove implicit conversion from int to float. 2014-04-01 10:56:07 +01:00
Dave Hylands baf6f14deb Enhance str.format support
This adds support for almost everything (the comma isn't currently
supported).

The "unspecified" type with floats also doesn't behave exactly like
python.

Tested under unix with float and double
Spot tested on stmhal

Paul Sokolovsky a96d3d0840 objexcept: No more magic messages in exceptions, only exception arguments.
One of the reason for separate "message" (besides still unfulfilled desire to
optimize memory usage) was apparent special handling of exception with
messages by CPython. Well, the message is still just an exception argument,
it just printed specially. Implement that with PRINT_EXC printing format.

Damien George e0f2979aed py: Add equality test for None object. 2014-03-30 23:16:42 +01:00
Damien George df6567e634 Merge map.h into obj.h.
Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation.  Thus, the definitions
are now in obj.h instead.  map.h is removed.
2014-03-30 13:54:02 +01:00
Damien George d17926db71 Rename rt_* to mp_*.
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

xbe c5d70ba48b Fix issues in str.count implementation.
See pull request #343.
2014-03-13 00:33:07 -07:00
xbe 9e1e8cd642 Implement str.count and add tests for it.
Also modify mp_get_index to accept:
1. Indices that are or evaluate to a boolean.
2. Slice indices.
Add tests for these two cases.
2014-03-12 22:57:16 -07:00
Damien George 0c36da0b59 Implement ROMable modules. Add math module.
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).
2014-03-08 15:24:39 +00:00
Damien George c5966128c7 Implement proper exception type hierarchy.
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.
2014-02-15 16:10:44 +00:00
Damien George a71c83a1d1 Change mp_obj_type_t.name from const char * to qstr.
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.
2014-02-15 11:34:50 +00:00
Paul Sokolovsky 4e836fb4ea mp_obj_equal(): Instead of assert(), throw NotImplementedError.
With a nice traceback, helps debugging much better.

Paul Sokolovsky 557c9d5264 unix microsocket: Add dummy makefile() method.
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.

Damien George 9aa2a527b5 py: Tidy up BINARY_OPs; negation done by special NOT bytecode.
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new
special NOT bytecode.
2014-02-01 23:04:09 +00:00
Damien George 09a0c64bce py: Improve __bool__ and __len__ dispatch; add slots for them. 2014-01-30 10:05:33 +00:00
Paul Sokolovsky c1d9bbc345 Implement __bool__ and __len__ via unary_op virtual method for all types.
__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.

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.

2014-01-04 20:21:15 +00:00
Damien George eb7bfcb286 Split qstr into pools, and put initial pool in ROM.
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).

Damien George 209d1b1835 py: add int() and float() built-ins, partially implemented. 2014-01-01 17:03:35 +00:00
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).
