2015-01-21py: Remove mp_obj_str_builder and use vstr instead.Damien George
With this patch str/bytes construction is streamlined. Always use a vstr to build a str/bytes object. If the size is known beforehand then use vstr_init_len to allocate only required memory. Otherwise use vstr_init and the vstr will grow as needed. Then use mp_obj_new_str_from_vstr to create a str/bytes object using the vstr memory. Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes on unix x64.
2015-01-20py, unix: Allow to compile with -Wunused-parameter.Damien George
See issue #699.
2015-01-16py, unix: Allow to compile with -Wsign-compare.Damien George
See issue #699.
2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-12-30py: Implement mp_obj_new_int_from_float() for MICROPY_LONGINT_IMPL_NONE.Paul Sokolovsky
2014-12-30py: Partially fix float to int conversion.Paul Sokolovsky
This fixes conversion when float type has more mantissa bits than small int, and float value has small exponent. This is for example the case of 32-bit platform using doubles, and converting value of time.time(). Conversion of floats with larg exponnet is still not handled correctly.
2014-12-05py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.Damien George
mp_obj_int_get_truncated is used as a "fast path" int accessor that doesn't check for overflow and returns the int truncated to the machine word size, ie mp_int_t. Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word sized values. Addresses issues #779 and #998.
2014-10-06py: Make int.to_bytes work on big endian machine.Damien George
Partly addresses issue #856.
2014-10-03py: Convert [u]int to mp_[u]int_t where appropriate.Damien George
Addressing issue #50.
2014-09-10py: Enable struct/binary-helper to parse q and Q sized ints.Damien George
Addresses issue #848.
2014-08-30py: Change uint to mp_uint_t in runtime.h, stackctrl.h, binary.h.Damien George
Part of code cleanup, working towards resolving issue #50.
2014-08-30py: Change all uint to mp_uint_t in obj.h.Damien George
Part of code cleanup, working towards resolving issue #50.
2014-08-30py: Save about 200 bytes of ROM by using smaller type for static table.Damien George
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.
2014-08-27py: Improve efficiency of MP_OBJ_IS_STR_OR_BYTES.Damien George
Saves ROM (16 on stmhal, 240 on 64-bit unix) and should be quicker since there is 1 less branch.
2014-08-26Make int(b'123') work properly.Dave Hylands
2014-08-13py: Fix mult by negative number of tuple, list, str, bytes.Damien George
Multiplication of a tuple, list, str or bytes now yields an empty sequence (instead of crashing). Addresses issue #799 Also added ability to mult bytes on LHS by integer.
2014-07-31py: Make MP_OBJ_NEW_SMALL_INT cast arg to mp_int_t itself.Damien George
Addresses issue #724.
2014-07-24py: Make long ints hashable.Damien George
Addresses issue #765.
2014-07-03Rename machine_(u)int_t to mp_(u)int_t.Damien George
See discussion in issue #50.
2014-06-06objint: Fix corner case in buffer access.Paul Sokolovsky
2014-06-01Rename bultins config variables to MICROPY_PY_BUILTINS_*.Damien George
This renames: MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT See issue #35 for discussion.
2014-05-28py: Fix check of small-int overflow when parsing ints.Damien George
Also unifies use of SMALL_INT_FITS macro across parser and runtime.
2014-05-28py: Make int(<longint>) work by just returning the longint.Damien George
2014-05-28py: Implement long int parsing in int(...).Damien George
Addresses issue #627.
2014-05-21py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George
See issue #608 for justification.
2014-05-17py: Fix mp_obj_t -> mp_const_obj_t for mp_obj_int_get_checked()Sven Wegener
Signed-off-by: Sven Wegener <sven.wegener@stealer.net>
2014-05-17py: More const usage.Paul Sokolovsky
2014-05-11py: Use mp_arg_check_num in more places.Damien George
Updated functions now do proper checking that n_kw==0, and are simpler because they don't have to explicitly raise an exception. Down side is that the error messages no longer include the function name, but that's acceptable. Saves order 300 text bytes on x64 and ARM.
2014-05-08Windows MSVC portstijn
Extend the windows port so it compiles with the toolchain from Visual Studio 2013
2014-05-07py: Improve native emitter; now supports more opcodes.Damien George
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/.
2014-05-02py, unix: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky
Specifically, nlr.h does.
2014-04-18py: Allow to pass buffer protocol flags to get_buffer helper funcs.Damien George
2014-04-18py: Add typecode to buffer protocol.Damien George
When querying an object that supports the buffer protocol, that object must now return a typecode (as per binary.[ch]). This does not have to be honoured by the caller, but can be useful for determining element size.
2014-04-17py: Add MP_OBJ_STOP_ITERATION and make good use of it.Damien George
Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL. This helps a lot in debugging and understanding of function API.
2014-04-13py: Oops, fix int.from_bytes to correctly convert bytes!Damien George
2014-04-13py: Make int.from_bytes a classmethod; support arbitrary length buf.Damien George
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.
2014-04-09objint: Implement int.from_bytes() class method and .to_bytes() method.Paul Sokolovsky
These two are apprerently the most concise and efficient way to convert int to/from bytes in Python. The alternatives are struct and array modules, but methods using them are more verbose in Python code and less efficient in memory/cycles.

2014-04-07Add string formatting support for longlong and mpz.Dave Hylands
2014-04-05py: Change nlr_jump to nlr_raise, to aid in debugging.Damien George
This does not affect code size or performance when debugging turned off. To address issue #420.
