* py: Overhaul and simplify printf/pfenv mechanism.Damien George2015-04-16
| | | | | | | | | | | | | | | | | | | | | | 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.
* py: Combine load_attr and store_attr type methods into one (attr).Damien George2015-04-11
| | | | | | This simplifies the API for objects and reduces code size (by around 400 bytes on Thumb2, and around 2k on x86). Performance impact was measured with Pystone score, but change was barely noticeable.
* py: Add support for start/stop/step attributes of builtin range object.Peter D. Gray2015-03-11

* py, unix: Allow to compile with -Wunused-parameter.Damien George2015-01-20
| | | | See issue #699.
* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* py: Convert [u]int to mp_[u]int_t where appropriate.Damien George2014-10-03
| | | | Addressing issue #50.
* Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George2014-08-30
| | | | Addressing issue #50, still some way to go yet.
* py: Improve range: add len, subscr, proper print.Damien George2014-08-12
| | | | | | | | Can now index ranges with integers and slices, and reverse ranges (although reversing is not very efficient). Not sure how useful this stuff is, but gets us closer to having all of Python's builtins.
* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | 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/.
* py, unix: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky2014-05-02
| | | | Specifically, nlr.h does.
* py: Add arg checking helper functions.Damien George2014-04-20
| | | | | | | These are to assist in writing native C functions that take positional and keyword arguments. mp_arg_check_num is for just checking the number of arguments is correct. mp_arg_parse_all is for parsing positional and keyword arguments with default values.
* py: Add MP_OBJ_STOP_ITERATION and make good use of it.Damien George2014-04-17
| | | | | Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL. This helps a lot in debugging and understanding of function API.
* py: Make built-in 'range' a class.Damien George2014-04-17
| | | | Addresses issue #487.
* py: Fix "TypeError: 'iterator' object is not iterable", doh.Paul Sokolovsky2014-03-30
|
* py: Replace mp_const_stop_iteration object with MP_OBJ_NULL.Damien George2014-03-26
|
* py: Clean up includes.xbe2014-03-17
| | | | Remove unnecessary includes. Add includes that improve portability.
* Implement proper exception type hierarchy.Damien George2014-02-15
| | | | | | | | | | | | | | 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.
* Change mp_obj_type_t.name from const char * to qstr.Damien George2014-02-15
| | | | | | 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.
* Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.Paul Sokolovsky2014-02-12
| | | | | | | | 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().
* Revamp qstrs: they now include length and hash.Damien George2014-01-21
| | | | | Can now have null bytes in strings. Can define ROM qstrs per port using qstrdefsport.h

* Convert many object types structs to use C99 tagged initializer syntax.Paul Sokolovsky2014-01-05
|
* Convert Python types to proper Python type hierarchy.Damien George2014-01-04
| | | | Now much more inline with how CPython does types.
* Change object representation from 1 big union to individual structs.Damien2013-12-21
A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
