See discussion in issue #50.

array.array and bytearray share big deal of code, so to get real savings,
both need to be disabled.
|
|
This will allow roughly the same behavior as Python3 for non-ASCII strings,
for example, print("<phrase in non-Latin script>".split()) will print list
of words, not weird hex dump (like Python2 behaves). (Of course, that it
will print list of words, if there're "words" in that phrase at all, separated
by ASCII-compatible whitespace; that surely won't apply to every human
language in existence).
|
|
Some small fixed:
- Combine 'x' and 'X' cases in str format code.
- Remove trailing spaces from some lines.
- Make exception messages consistently begin with lower case (then
needed to change those in objarray and objtuple so the same
constant string data could be used).
- Fix bug with exception message having %c instead of %%c.

See issue #608 for justification.

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/.
|
|
Specifically, nlr.h does.
|
|
Also, clear up freed slots in containers.
As a follow up to 32bef315be8e56ad2d7f69223fe7b9606893b6ab.

Also, checked that both bytearray and array.array actually support generic
(a-la list) slice assignment and deletion. Added TODOs.
|
|
|
|
These are to assist in writing native C functions that take positional
and keyword arguments. mp_arg_check_num is for just checking the
number of arguments is correct. mp_arg_parse_all is for parsing
positional and keyword arguments with default values.

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.
|
|
|
|
Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL.
This helps a lot in debugging and understanding of function API.
|
|
mp_obj_t->subscr now does load/store/delete.
|
|
|
|
This makes the runtime and object APIs more consistent. mp_store_subscr
functionality now moved into objects (ie list and dict store_item).
|
|
|
|
To create bytearray of given length.
|
|
This does not affect code size or performance when debugging turned off.
To address issue #420.

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.
|
|
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.

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.

Addresses issue #377.
|
|
|
|
Comes with some refactoring of code and renaming of files. All modules
are now named mod*.[ch].
|
|
Remove unnecessary includes. Add includes that improve portability.
|
|
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.
|
|
Don't need to wrap bitfields in their own struct. Compiler does the
correct thing without it.
|
|
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.
|
|
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.
|
|
|
|
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().
|
|
Can't decide which is better for string type, char or byte pointer.
Changing to char removes a few casts. Really need to do proper unicode.
|
|
__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.
|
|
This is special feature for FFI.
