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.
py: Add MICROPY_COMP_{DOUBLE,TRIPLE}_TUPLE_ASSIGN config options.2015-03-14T13:11:35+00:00Damien Georgedamien.p.george@gmail.com2015-03-14T13:11:35+00:00urn:sha1:42e0c593084784cb0b630d99b8361bc88abadb78
These allow to fine-tune the compiler to select whether it optimises
tuple assignments of the form a, b = c, d and a, b, c = d, e, f.
Sensible defaults are provided.
py: Protect mp_parse and mp_compile with nlr push/pop block.2015-02-07T18:33:58+00:00Damien Georgedamien.p.george@gmail.com2015-02-07T18:33:58+00:00urn:sha1:0bfc7638baa4c5a4a2351364ab770a188dcab302
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.
This patch adds that feature in all places. This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.
py: Add config option MICROPY_COMP_MODULE_CONST for module consts.2015-01-10T14:07:24+00:00Damien Georgedamien.p.george@gmail.com2015-01-10T14:07:24+00:00urn:sha1:ddd1e188011a021537c87c75f0a9e1818e335d5d
Compiler optimises lookup of module.CONST when enabled (an existing
feature). Disabled by default; enabled for unix, windows, stmhal.
Costs about 100 bytes ROM on stmhal.

This patch consolidates all global variables in py/ core into one place,
in a global structure. Root pointers are all located together to make
GC tracing easier and more efficient.

The function is modeled after traceback.print_exception(), but unbloated,
and put into existing module to save overhead on adding another module.
Compliant traceback.print_exception() is intended to be implemented in
micropython-lib in terms of sys.print_exception().
This change required refactoring mp_obj_print_exception() to take pfenv_t
interface arguments.
Addresses #751.
