988,libsoy bitpacker,ArcRiley,ArcRiley,"In order to support import/export methods for PySoy classes cleanly we need a class which can handle packing and unpacking data of arbitrary meaning and bit length.

Methods of this class may include;

{{{read_uint(bits : int) : int}}} to read a number of bits from the stream, from 1 to 32, and return them as an integer.

{{{read_int(bits : int) : int}}} to read 1 to 31 bits plus a sign bit (highest order)

{{{read_bool() : bool}}} is an alias for {{{(bool) read_uint(1)}}}

{{{read_double() : double}}} to read 64 bits and return a double

{{{read_label() : string}}} to read a byte for length then 0-255 bytes which are returned as a string.

{{{read_nstring(bytes : int) : string}}} reads the specified number of bytes and returns a string.  Useful for when the format specifies fixed-length strings or in cases where strings of > 255 bytes are needed.

... and the write versions of these as well.

Byte packing should be in network byte order (most significant byte first) and converted to/from native byte order.",defect,assigned,High,beta3,Importer,Trunk,,,
