NEWS:
library/bit_buffer.m:
library/bit_buffer.read.m:
library/bit_buffer.write.m:
Add bit_buffers to the standard library. A bit_buffer
provides a bit-oriented interface to byte streams.
These will be used as a base for write_binary and read_binary.
library/stream.m:
Add class which supports reading multiple items at once into
a store.
Clarify the blocking behaviour of `put' and `get'.
Document the behaviour of subsequent calls to `get'
after a call returns eof or an error.
library/bitmap.m:
Add a shorthand for `new(N, no)'.
Add `shrink_without_copying' to destructively shrink a bitmap
without copying the data.
Add a function `append_list' to condense a list of bitmaps.
Improve bounds error messages.
Clean up the handling of zero-length bit ranges.
Add type `bitmap.slice' to represent a segment of a bitmap,
and functions to create slices.
library/io.m:
Change the interface of io.read_bitmap to conform to
the stream.bulk_reader interface, by not returning the
bitmap inside the return code. The bitmap is still
valid (although maybe not completely filled) no matter
what result is returned.
Add io.read_binary_file_as_bitmap/N.
library/library.m:
Add recent additions to the list of library modules.
library/Mercury.options:
Use "+=" rather than "=" when setting target-specific
options to allow them to be added to be Mmake.params.
tests/hard_coded/Mmakefile:
tests/hard_coded/bit_buffer_test.m:
tests/hard_coded/bit_buffer_test.exp:
Test case.
tests/hard_coded/bitmap_test.m:
tests/hard_coded/bitmap_simple.m:
tests/hard_coded/bitmap_test.exp:
Update for change to io.read_bitmap.
Test bounds error messages.
