Paul Sokolovsky fb7f94392d import: Implement "from pkg.mod import sym" syntax properly.
http://docs.python.org/3.3/library/functions.html#__import__ :
"When the name variable is of the form package.module, normally, the
top-level package (the name up till the first dot) is returned, not
the module named by name. However, when a non-empty fromlist argument
is given, the module named by name is returned."

Dave Hylands 51dabac096 Add pin mapping code.
This commit also introduces board directories and moves board
specific config into the appropriate board directory.

boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet
and hand-tweaked.

make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c,
and boards/BOARD-NAME/pins.csv as input and generates the file
build/pins_BOARD_NAME.c

The generated pin file for PYBOARD4 looks like this:
https://gist.github.com/dhylands/9063231

The generated pins file includes all of the supported alternate
functions, and includes upsupported alternate functions as comments.

See the commnet block at the top of stm/pin_map.c for details on
how to use the pin mapper.

I also went ahead and modified stm/gpio.c to use the pin mapper.

Paul Sokolovsky 4d0588df56 objint_longlong: Don't assert on invalid syntax, raise SyntaxError instead. 2014-02-18 00:22:19 +02:00
Paul Sokolovsky 4aee119f94 stm: Initialize sys.path with ["0:/", "0:/src", "0:/lib"].
This is compatible with what search path was before sys.path refactor,
with addition of module library path ("0:/lib").

Paul Sokolovsky ac2e28c654 Support passing positional args as keywords to bytecode functions.
For this, record argument names along with each bytecode function. The code
still includes extensive debug logging support so far.
2014-02-16 18:36:33 +02:00
Paul Sokolovsky 44739e280e Make DEBUG_printf() a proper function, implementation is port-dependent.
In particular, unix outputs to stderr, to allow to run testsuite against
micropython built with debug output (by redirecting stderr to /dev/null).

of the implemented behavior.

throwing exceptions, etc.

Damien George 8725f8f7de py: Pass all scope flags through to runtime. 2014-02-15 19:33:11 +00:00
Damien George c5966128c7 Implement proper exception type hierarchy.
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.
2014-02-15 16:10:44 +00:00
Damien George a71c83a1d1 Change mp_obj_type_t.name from const char * to qstr.
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.

Paul Sokolovsky 520e2f58a5 Replace global "static" -> "STATIC", to allow "analysis builds". Part 2. 2014-02-12 18:31:30 +02:00
Paul Sokolovsky d5df6cd44a Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.
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().

If there's malloc and memset, then there's no need for calloc, especially if
we need to implement it ourselves.

Paul Sokolovsky 557c9d5264 unix microsocket: Add dummy makefile() method.

Damien George 0a587b85fb py: Pass keyword args to native functions by using the stack.
Passing keyword arguments to a native function now no longer requires

Damien George 698ec21e46 Make mp_obj_str_get_data return char* instead of byte*.
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.

Paul Sokolovsky e11b17c25f Implement support for sys.path when loading modules.
sys.path is not initialized by rt_init(), that's left for platform-specific
startup code. (For example, bare metal port may have some hardcoded defaults,
and let user change sys.path directly; while port for OS with environment
feature can take path from environment). If it's not explicitly initialized,
modules will be imported only from a current directory.

TODO: Decide if we really need separate bytecode for creating functions

good shape, and unwinding shouldn't be required.
