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.
2014-04-07Fix truncation problem when using longlong implementation.Dave Hylands
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.
2014-04-04py: Make False and True act like 0 and 1 for integer arithmetic.Damien George
2014-04-02py: Allow multiple of str/list/tuple on left by an integer.Damien George
2014-03-30py: Add explicit conversion from float to int via int().Damien George
2014-03-29py: Rename old const type objects to mp_type_* for consistency.Damien George
2014-03-22py: Add function to convert long int to float.Damien George
2014-03-17py: Clean up includes.xbe
Remove unnecessary includes. Add includes that improve portability.
2014-03-12py: Implement integer overflow checking for * and << ops.Damien George
If operation will overflow, a multi-precision integer is created.
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).
2014-02-22py: Put number parsing code together in parsenum.c.Damien George
2014-02-22py: Rename strtonum to mp_strtonum.Damien George
strtonum clashes with BSD function of same name, and our version is different so warrants a unique name. Addresses Issue #305.
2014-02-22py: Fix casting and printing of small int.Damien George
2014-02-15Implement proper exception type hierarchy.Damien George
Each built-in exception is now a type, with base type BaseException. C exceptions are created by passing a pointer to the exception type to make an instance of. When raising an exception from the VM, an instance is created automatically if an exception type is raised (as opposed to an exception instance). Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper. Handling of parse error changed to match new exceptions. mp_const_type renamed to mp_type_type for consistency.
2014-02-15Change mp_obj_type_t.name from const char * to qstr.Damien George
Ultimately all static strings should be qstr. This entry in the type structure is only used for printing error messages (to tell the type of the bad argument), and printing objects that don't supply a .print method.
2014-02-12Remove mp_obj_new_exception_msg_1_arg and _2_arg.Damien George
2014-02-12Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.Paul Sokolovsky
Some tools do not support local/static symbols (one example is GNU ld map file). Exposing all functions will allow to do detailed size comparisons, etc. Also, added bunch of statics where they were missing, and replaced few identity functions with global mp_identity().
2014-02-08Make mp_obj_str_get_data return char* instead of byte*.Damien George
Can't decide which is better for string type, char or byte pointer. Changing to char removes a few casts. Really need to do proper unicode.
2014-01-27long int: Implement more operations.Paul Sokolovsky
2014-01-22Second stage of qstr revamp: uPy str object can be qstr or not.Damien George
2014-01-21Revamp qstrs: they now include length and hash.Damien George
Can now have null bytes in strings. Can define ROM qstrs per port using qstrdefsport.h
