Damien George 612045f53f py: Add native json printing using existing print framework.
Also add start of ujson module with dumps implemented.  Enabled in unix
and stmhal ports.  Test passes on both.

Damien George 8a9b999f1c py: Make dict use a bit less RAM when iterating; properly del values.
Heap RAM was being allocated to print dicts and do some other types of
iterating.  Now these iterations use 1 word of state on the stack.

Deleting elements from a dict was not allowing the value to be reclaimed
by the GC.  This is now fixed.

Damien George 93965e726f py: Make map, dict, set use mp_int_t/mp_uint_t exclusively.
Part of code cleanup, towards resolving issue #50.
2014-08-30 13:23:35 +01:00
Damien George ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int.
Addressing issue #50, still some way to go yet.
2014-08-30 00:35:11 +01:00
Damien George bb4c6f35c6 py: Make MP_OBJ_NEW_SMALL_INT cast arg to mp_int_t itself.
Addresses issue #724.
2014-07-31 10:49:14 +01:00
Damien George 40f3c02682 Rename machine_(u)int_t to mp_(u)int_t.
See discussion in issue #50.

Paul Sokolovsky 75ce9256b2 objstr: Implement "%(key)s" % {} formatting for strings and dicts.
Also, make sure that args to "*" format specifiers are bounds-checked
properly and don't lead for segfaults in case of mismatch.
2014-06-05 20:06:15 +03:00
Damien George bcb6ca4d5e py: Implement full behaviour of dict.update(), and dict().
Add keyword args to dict.update(), and ability to take a dictionary as
argument.

dict() class constructor can now use dict.update() directly.

This patch loses fast path for dict(other_dict), but is that really
needed?  Any anyway, this idiom will now re-hash the dictionary, so is
arguably more memory efficient.

Addresses issue #647.
2014-06-03 12:53:44 +01:00
Damien George 6ac5dced24 py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.
See issue #608 for justification.
2014-05-21 19:42:43 +01:00
Damien George d0a5bf34f7 py: Tidy up returning NULL which should be MP_OBJ_NOT_SUPPORTED. 2014-05-10 13:55:11 +01:00
Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
2014-05-03 23:27:38 +01:00
Paul Sokolovsky f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it.
Specifically, nlr.h does.
2014-05-02 17:48:40 +03:00
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 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 686afc5c0a py: Check that sequence has 2 elements for dict iterable constructor. 2014-04-11 09:13:30 +01:00
Paul Sokolovsky be019ce063 objdict: Implement construction from iterable of pairs.
Pairs are limited to tuples so far.

Paul Sokolovsky 12a04392b9 objdict: Implement __getitem__ method. 2014-04-11 05:24:44 +03:00
Damien George f4c9b33abf py: Remove DELETE_SUBSCR opcode, combine with STORE_SUBSCR.
This makes the runtime and object APIs more consistent.  mp_store_subscr
functionality now moved into objects (ie list and dict store_item).
2014-04-08 21:32:29 +01:00
Paul Sokolovsky 7cf057aeeb objdict: Implement equality operator.
Sure, it's O(n^2).
2014-04-06 21:31:42 +03:00
Paul Sokolovsky 5fedd0c3b7 py: Fix dict.copy() and low-level map/set allocation.
Two things: 1) set flags in copy properly; make mp_map_init() not be too
smart and do something with requested alloc size. Policy of using prime
numbers for alloc size is high-level policy which should be applied at
corresponding high levels. Low-level functions should just do what they're
asked to, because they don't have enough context to be smarter than that.
For example, munging with alloc size of course breaks dict copying (as
changing sizes requires rehashing).

Damien George 8b0535e23f py: Change module globals from mp_map_t* to mp_obj_dict_t*.
Towards addressing issue #424.

Had a small increase to ROM usage (order 60 bytes).
2014-04-05 21:53:54 +01:00
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.

Damien George 95004e5114 py: Fix delete operation on map/dict and set objects.
Hash table can now be completely full (ie now NULL entry) before a
resize is triggered.  Use sentinel value to indicate delete entry in the
table.

Damien George 15d18069c5 py: Remove old "run time" functions that were 1 liners. 2014-03-31 16:28:13 +01:00
Paul Sokolovsky f7eaf605c0 py: Fix "TypeError: 'iterator' object is not iterable", doh. 2014-03-30 23:37:24 +03:00
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.
2014-03-30 13:35:08 +01:00
Damien George 3e1a5c10c5 py: Rename old const type objects to mp_type_* for consistency. 2014-03-29 13:43:38 +00:00
Damien George 9b196cddab Remove mp_obj_type_t.methods entry and use .locals_dict instead.
Originally, .methods was used for methods in a ROM class, and
locals_dict for methods in a user-created class.  That distinction is
unnecessary, and we can use locals_dict for ROM classes now that we have
ROMable maps.

This removes an entry in the bloated mp_obj_type_t struct, saving a word
for each ROM object and each RAM object.  ROM objects that have a
methods table (now a locals_dict) need an extra word in total (removed
the methods pointer (1 word), no longer need the sentinel (2 words), but
now need an mp_obj_dict_t wrapper (4 words)).  But RAM objects save a
word because they never used the methods entry.

Overall the ROM usage is down by a few hundred bytes, and RAM usage is
down 1 word per user-defined type/class.

There is less code (no need to check 2 tables), and now consistent with
the way ROM modules have their tables initialised.

Efficiency is very close to equivaluent.

Damien George c12b2213c1 Change mp_method_t.name from const char * to qstr.
Addresses issue #377.

Damien George 66eaf84b8c py: Replace mp_const_stop_iteration object with MP_OBJ_NULL. 2014-03-26 19:27:58 +00:00
xbe efe3422394 py: Clean up includes.
Remove unnecessary includes. Add includes that improve portability.
2014-03-17 02:43:40 -07:00
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 d5df6cd44a Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.
Some tools do not support local/static symbols (one example is GNU ld map file).
Exposing all functions will allow to do detailed size comparisons, etc.

Also, added bunch of statics where they were missing, and replaced few identity
functions with global mp_identity().

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.
2014-01-30 04:37:19 +02:00
Damien George 4e8dc8c41b py: Add unary op not for NoneType, bool, tuple, list, dict; fix for int. 2014-01-27 23:15:32 +00:00
Damien George 55baff4c9b Revamp qstrs: they now include length and hash.
Can now have null bytes in strings.  Can define ROM qstrs per port using
qstrdefsport.h
2014-01-21 21:40:13 +00:00
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 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.

Damien George eae16445d5 py: Implement staticmethod and classmethod (internally).
Still need to make built-ins by these names, and write tests.
2014-01-11 19:22:29 +00:00
John R. Lenton c1bef21920 Implemented support for `in` and `not in` operators. 2014-01-11 12:39:33 +00:00
John R. Lenton 4bee76ebca Added dict.fromkeys. Are we done with dict and #99 yet? I do think we are. 2014-01-10 11:25:03 +00:00
John R. Lenton 9ec3a87189 dict views now, refactoring later. 2014-01-10 01:00:20 +00:00
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.
2014-01-09 20:57:50 +00:00
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

John R. Lenton a41fe31322 Added dict iterator. 2014-01-07 22:51:08 +00:00
Paul Sokolovsky 860ffb0a43 Convert many object types structs to use C99 tagged initializer syntax. 2014-01-05 22:34:09 +02:00
Damien George 71c5181a8d Convert Python types to proper Python type hierarchy.
Now much more inline with how CPython does types.
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 dae7eb7226 py: add dict length function, and fix rt_store_set. 2013-12-29 22:32:51 +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).
