2015-12-02py/mpprint: Printing of doubles is now supported (by uPy own routine).fabien.lementec
2015-11-29py: Change qstr_* functions to use size_t as the type for str len arg.Damien George
2015-11-29py: Change mp_print_strn_t func type to use size_t for the str length.Damien George
2015-10-31all: Add py/mphal.h and use it in all ports.Damien George
py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations.
2015-05-28py: Remove unnecessary extra handling of padding of nan/inf.Damien George
C's printf will pad nan/inf differently to CPython. Our implementation originally conformed to C, now it conforms to CPython's way. Tests for this are also added in this patch.
2015-05-28py: Reduce size of mp_printf by eliminating unnecessary code.Damien George
Saves around 120 bytes on Thumb2 archs.
2015-05-17py: Implement mp_format_float for doubles and use where appropriatestijn
This allows using (almost) the same code for printing floats everywhere, removes the dependency on sprintf and uses just snprintf and applies an msvc-specific fix for snprintf in a single place so nan/inf are now printed correctly.
2015-04-16py: Add %q format support to mp_[v]printf, and use it.Damien George
2015-04-16py: Overhaul and simplify printf/pfenv mechanism.Damien George
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.
