2020-05-28py/modsys: Use consistent naming pattern for module-level const objects.David Lechner
This renames a few identifiers to follow the usual naming convention of mp_<module>_<name>. This makes them easier to find, e.g. when grep'ing.
2020-02-28all: Reformat C and Python source code with tools/codeformat.py.Damien George
This is run with uncrustify 0.70.1, and black 19.10b0.
2017-09-18py/modbuiltins: Implement abs() by dispatching to MP_UNARY_OP_ABS.Paul Sokolovsky
This allows user classes to implement __abs__ special method, and saves code size (104 bytes for x86_64), even though during refactor, an issue was fixed and few optimizations were made: * abs() of minimum (negative) small int value is calculated properly. * objint_longlong and objint_mpz avoid allocating new object is the argument is already non-negative.
2017-08-29all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriateDamien George
The unary-op/binary-op enums are already defined, and there are no arithmetic tricks used with these types, so it makes sense to use the correct enum type for arguments that take these values. It also reduces code size quite a bit for nan-boxing builds.
2017-07-31all: Use the name MicroPython consistently in commentsAlexander Steffen
There were several different spellings of MicroPython present in comments, when there should be only one.
2017-07-18all: Unify header guard usage.Alexander Steffen
The code conventions suggest using header guards, but do not define how those should look like and instead point to existing files. However, not all existing files follow the same scheme, sometimes omitting header guards altogether, sometimes using non-standard names, making it easy to accidentally pick a "wrong" example. This commit ensures that all header files of the MicroPython project (that were not simply copied from somewhere else) follow the same pattern, that was already present in the majority of files, especially in the py folder. The rules are as follows. Naming convention: * start with the words MICROPY_INCLUDED * contain the full path to the file * replace special characters with _ In addition, there are no empty lines before #ifndef, between #ifndef and one empty line before #endif. #endif is followed by a comment containing the name of the guard macro. py/grammar.h cannot use header guards by design, since it has to be included multiple times in a single C file. Several other files also do not need header guards as they are only used internally and guaranteed to be included only once: * MICROPY_MPHALPORT_H * mpconfigboard.h * mpconfigport.h * mpthreadport.h * pin_defs_*.h * qstrdefs*.h
2017-04-04py/objint: Consolidate mp_obj_new_int_from_float to one implementation.Damien George
This reduces code duplication and allows to make mp_classify_fp_as_int static, which reduces code size.
2017-02-02py: Added optimised support for 3-argument calls to builtin.pow()Nicko van Someren
Updated modbuiltin.c to add conditional support for 3-arg calls to pow() using MICROPY_PY_BUILTINS_POW3 config parameter. Added support in objint_mpz.c for for optimised implementation.
2017-01-21py/objint: from_bytes(): Implement "byteorder" param and arbitrary precision.Paul Sokolovsky
If result guaranteedly fits in a small int, it is handled in objint.c. Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should be implemented by individual objint_*.c, similar to mp_obj_int_to_bytes_impl().
2016-12-21py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.Damien George
And also simplify it to remove the check for small int. This can be done because this function is only ever called if the argument is not a small int.
2016-10-11py/objint: Use size_t for arguments that measure bytes/sizes.Damien George
2016-10-11py: Factor duplicated function to calculate size of formatted int.Damien George
2016-01-07py: Change mp_obj_int_is_positive to more general mp_obj_int_sign.Damien George
This function returns the sign (-1, 0 or 1) of the integer object.
2015-04-25py: Support conversion of bignum to bytes.Damien George
This gets int.to_bytes working for bignum, and also struct.pack with 'q' and 'Q' args on 32-bit machines. Addresses issue #1155.
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.
2015-03-14py: Fix builtin abs so it works for bools and bignum.Damien George
2015-01-24py: Add float-to-int classification functionDavid Steinberg
2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-10-03py: Convert [u]int to mp_[u]int_t where appropriate.Damien George
Addressing issue #50.
2014-09-15py: Move definition of mp_sys_exit to core.Damien George
sys.exit always raises SystemExit so doesn't need a special implementation for each port. If C exit() is really needed, use the standard os._exit function. Also initialise mp_sys_path and mp_sys_argv in teensy port.
2014-08-30Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George
Addressing issue #50, still some way to go yet.
2014-07-24py: Make long ints hashable.Damien George
Addresses issue #765.
2014-05-17py: More const usage.Paul Sokolovsky
2014-05-03Add license header to (almost) all files.Damien George
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/.
2014-04-08py: Make it so that printing a small int does not allocate heap memory.Damien George
With the implementation of proper string formatting, code to print a small int was delegated to mpz_as_str_inpl (after first converting the small int to an mpz using stack memory). But mpz_as_str_inpl allocates heap memory to do the conversion, so small ints needed heap memory just to be printed. This fix has a separate function to print small ints, which does not allocate heap, and allocates less stack. String formatting, printf and pfenv are now large beasts, with some semi-duplicated code.
2014-04-07Add string formatting support for longlong and mpz.Dave Hylands
2014-04-04py: Make False and True act like 0 and 1 for integer arithmetic.Damien George
2014-02-22Add arbitrary precision integer support.Damien George
Some functionality is still missing (eg and, or, bit shift), and some things are buggy (eg subtract).

2014-02-15Small change to configuration of long int.Damien George
2014-02-14ffi: Implement ffivar.get()/set() methods.Paul Sokolovsky
Done by introducing another factored out helper API in binary.c. This API can be reused also by array and struct modules.
