Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation. Thus, the definitions
are now in obj.h instead. map.h is removed.
|
|
Mostly just a global search and replace. Except rt_is_true which
becomes mp_obj_is_true.
Still would like to tidy up some of the names, but this will do for now.

Originally, .methods was used for methods in a ROM class, and
locals_dict for methods in a user-created class. That distinction is
unnecessary, and we can use locals_dict for ROM classes now that we have
ROMable maps.
This removes an entry in the bloated mp_obj_type_t struct, saving a word
for each ROM object and each RAM object. ROM objects that have a
methods table (now a locals_dict) need an extra word in total (removed
the methods pointer (1 word), no longer need the sentinel (2 words), but
now need an mp_obj_dict_t wrapper (4 words)). But RAM objects save a
word because they never used the methods entry.
Overall the ROM usage is down by a few hundred bytes, and RAM usage is
down 1 word per user-defined type/class.
There is less code (no need to check 2 tables), and now consistent with
the way ROM modules have their tables initialised.
Efficiency is very close to equivaluent.

Addresses issue #377.

Remove unnecessary includes. Add includes that improve portability.

mp_module_obj_t can now be put in ROM.
Configuration of float type is now similar to longint: can now choose
none, float or double as the implementation.
math module has basic math functions. For STM port, these are not yet
implemented (they are just stub functions).

This change allows to build unix version without libreadline installed.
|
|
|
|
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).
|
|
In particular, unix outputs to stderr, to allow to run testsuite against
micropython built with debug output (by redirecting stderr to /dev/null).
|
|
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.

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.

OS X compatible -map syntax for LDFLAGS
|
|
Allow ports to define statically builtin functions.
|
|
|
|
Done by introducing another factored out helper API in binary.c. This API
can be reused also by array and struct modules.
|
|
Convert unix open() to such.
|
|
To allow easily try different optimization and configuration options
without patching any files.
|
|
Enable GC for Unix port

Unlike CPython socket, microsocket object already implements stream protocol
(read/write methods), so makefile() just returns object itself. TODO: this
doesn't take care of arguments CPython's makefile() may accept.
|
|
|
|
Implementation is duplicated, but tolerate this for now, because there's
no clear idea how to de-dup it.
|
|
It's no longer intended to provide just "raw" socket interface, may include
some convenience methods for compatibility with CPython socket - but anyway
just minimal set required to deal with socket client and servers, not wider
network functionality.
|
|
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.

This mirrors CPython behavior and makes possible to run scripts which
import other modules not from script's directory.
|
|
If it's not available, "~/.micropython/lib:/usr/lib/micropython" is used
as a fallback.

Both return int so far (single-precision float doesn't have enough
bits to represent int32 precisely).
|
|
Hopefully this works for other people as well :)
|
|
Proof of concept, controls "ffi" module as one which requires external
dependencies.
