Damien George 9472907ae1 py: Fix handling of negative numbers in struct.pack of q/Q. 2015-04-25 23:51:14 +01:00
Damien George 271d18eb08 py: Support conversion of bignum to bytes. 
This gets int.to_bytes working for bignum, and also struct.pack with 'q'
and 'Q' args on 32-bit machines.

Addresses issue #1155.
 2015-04-25 23:16:39 +01:00
Paul Sokolovsky 24c1000741 objarray: Support array('O'), array of objects, as extension to CPython. 
Might be useful at least for memoryview hacks.

David Steinberg 0b3014ce3a py: Add support for floats in mp_binary_{get,set}_val() 
- This then provides support for floats in the struct package
 2015-01-27 22:49:01 +02:00
Paul Sokolovsky 91232d3850 binary: Rework array accessors. They work with native, not stdint types. 2015-01-24 03:18:33 +02:00
Damien George 963a5a3e82 py, unix: Allow to compile with -Wsign-compare. 
See issue #699.
 2015-01-16 17:47:07 +00:00
Damien George 51dfcb4bb7 py: Move to guarded includes, everywhere in py/ core. 
Addresses issue #1022.
 2015-01-01 20:32:09 +00:00
Damien George be6d8be91e py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack. 
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.

Fixes #691.
 2014-06-21 22:43:22 +03:00
Paul Sokolovsky 62798831be modstruct: Add one more extension to typecodes - 'S', a pointer to C string. 
Also, add comment with description of extension to CPython's typecodes.
 2014-06-02 16:35:56 +03:00
Damien George fb510b3bf9 Rename bultins config variables to MICROPY_PY_BUILTINS_*. 
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.

Damien George 04b9147e15 Add license header to (almost) all files. 
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/.
 2014-05-03 23:27:38 +01:00
Paul Sokolovsky 0f836ef893 modstruct: Add 'O' typecode for passing mp_obj_t. 
Useful as callback data, etc.

Paul Sokolovsky 6204460461 modstruct: Initial implementation of struct.pack(). 2014-04-19 03:22:08 +03:00
Paul Sokolovsky 1355cf42f2 modstruct: Fix .calcsize() to account for struct type/alignment. 2014-04-19 03:21:06 +03:00

Paul Sokolovsky ef9124f5ff binary: Rename array accessors for clarity. 2014-04-11 03:58:49 +03:00
Paul Sokolovsky 6582d64d01 modstruct: Refactor to support both LE and BE packed structs. 2014-04-11 03:58:49 +03:00
Paul Sokolovsky e9db840480 py: Start implementing "struct" module. 
Only calcsize() and unpack() functions provided so far, for little-endian
byte order. Format strings don't support repition spec (like "2b3i").

Unfortunately, dealing with all the various binary type sizes and alignments
will lead to quite a bloated "binary" helper functions  - if optimizing for
speed. Need to think if using dynamic parametrized algos makes more sense.

xbe efe3422394 py: Clean up includes. 
Remove unnecessary includes. Add includes that improve portability.
 2014-03-17 02:43:40 -07:00
Damien George 438c88dd2f Add arbitrary precision integer support. 
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).

Paul Sokolovsky 8bc3516389 ffi: Implement ffivar.get()/set() methods. 
Done by introducing another factored out helper API in binary.c. This API
can be reused also by array and struct modules.
