Our implementation originally conformed to C, now it conforms to CPython's way. Tests for this are also added in this patch. py: Reduce size of mp_printf by eliminating unnecessary code. 2015-05-28T13:54:56+00:00 Damien George damien.p.george@gmail.com 2015-05-28T13:54:56+00:00 urn:sha1:2cae0f62908812b6cd925943ee70e7e0bef0387e Saves around 120 bytes on Thumb2 archs. py: Make mp_sys_stdout_print object, wrapping sys.stdout for mp_print*. 2015-04-16T14:30:16+00:00 Damien George damien.p.george@gmail.com 2015-04-11T11:01:39+00:00 urn:sha1:5ae5ec986ea5e14321f6c8091454c165c23b40c5 So now all printing should go via either mp_plat_print or mp_sys_stdout_print. py: Overhaul and simplify printf/pfenv mechanism. 2015-04-16T14:30:16+00:00 Damien George damien.p.george@gmail.com 2015-04-09T22:56:15+00:00 urn: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.
