Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset
Allows to call the following without heap memory:
- all, any, min, max, sum
TODO: still need to allocate stack memory in bytecode for iter_buf.
py/objtuple: Convert mp_uint_t to size_t where appropriate.2017-02-16T05:51:16+00:00Damien Georgedamien.p.george@gmail.com2017-02-16T05:09:51+00:00urn:sha1:229823942c79b1233c43dc155bae01c20a8cec57py: Add MP_ROM_* macros and mp_rom_* types and use them.2015-11-29T14:25:04+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T13:38:15+00:00urn:sha1:cbf7674025814797f5c537d6d1c195efe58ccaafpy: Add attrtuple object, for space-efficient tuples with attr access.2015-04-21T14:14:24+00:00Damien Georgedamien.p.george@gmail.com2015-04-21T14:14:24+00:00urn:sha1:5aa311d33084c24262780cae0a65d748990ce7e1
If you need the functionality of a namedtuple but will only make 1 or a
few instances, then use an attrtuple instead.
py: Overhaul and simplify printf/pfenv mechanism.2015-04-16T14:30:16+00:00Damien Georgedamien.p.george@gmail.com2015-04-09T22:56:15+00:00urn:sha1:7f9d1d6ab923096582622b700bedb6a571518eac
Previous to this patch the printing mechanism was a bit of a tangled
mess. This patch attempts to consolidate printing into one interface.
All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf. All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.
Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform. The former is only used when MICROPY_PY_IO is defined.
With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...). Code size is also reduced by around 200 bytes on
Thumb2 archs.

Addresses issue #1022.
Change some parts of the core API to use mp_uint_t instead of uint/int.2014-08-29T23:35:11+00:00Damien Georgedamien.p.george@gmail.com2014-08-29T23:35:11+00:00urn:sha1:ecc88e949ca5e307d22da4605a40d39ea2df9e3b
Addressing issue #50, still some way to go yet.
Rename machine_(u)int_t to mp_(u)int_t.2014-07-03T12:25:24+00:00Damien Georgedamien.p.george@gmail.com2014-07-03T12:25:24+00:00urn:sha1:40f3c026823f8951a2fa04e9c7fc93c75bc27bec
See discussion in issue #50.
py: Rename globally-accessible tuple functions, prefix with mp_obj_.2014-05-11T17:00:45+00:00Damien Georgedamien.p.george@gmail.com2014-05-11T17:00:45+00:00urn:sha1:2323ef9182f9b57b96c7b4e1b414c18591a00bff
Likely there are other functions that should be renamed, but this is a
start.
