Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word sized values. Addresses issues #779 and #998. modstruct: Fix alignment handling issues. 2014-06-25T20:34:44+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-06-25T19:25:53+00:00 urn:sha1:7a2f16694907fbe8bf5445e30d061f4bb1f9517a Also, factor out mp_binary_get_int() function. modstruct: Implement count specifier for strings (e.g. "100s"). 2014-05-12T20:45:50+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-05-12T20:45:50+00:00 urn:sha1:df94b717b42bea39c1794a38bc10254e4f924e22 Infra for counts of other types is there, need last mile to be implemented. modstruct: Initial implementation of struct.pack(). 2014-04-19T00:22:08+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-04-19T00:13:15+00:00 urn:sha1:6204460461cc21b27861fa89b2423119f8cdce88 modstruct: Basic implementation of native struct alignment and types. 2014-04-11T00:59:16+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-04-11T00:47:21+00:00 urn:sha1:0c43cf9154e331ab82bec7c727bc58307f8222c5 modstruct: Refactor to support both LE and BE packed structs. 2014-04-11T00:58:49+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-04-10T19:19:32+00:00 urn:sha1:6582d64d01c448be4f575f964c549e1ebffe0db0 py: Start implementing "struct" module. 2014-04-10T00:58:03+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-04-10T00:45:38+00:00 urn:sha1:e9db8404804f2eed07eb0a6190f73ae21e0dc43c 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.
