Anywhere a module is mentioned, use its "non-u" name for consistency. The "import module" vs "import umodule" is something of a FAQ, and this commit intends to help clear that up. As a first approximation MicroPython is Python, and so imports should work the same as Python and use the same name, to a first approximation. The u-version of a module is a detail that can be learned later on, when the user wants to understand more and have finer control over importing. Existing Python code should just work, as much as it is possible to do that within the constraints of embedded systems, and the MicroPython documentation should match the idiomatic way to write Python code. With universal weak links for modules (via MICROPY_MODULE_WEAK_LINKS) users can consistently use "import foo" across all ports (with the exception of the minimal ports). And the ability to override/extend via "foo.py" continues to work well. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>

:mod:`zlib` -- zlib decompression
|
|
=================================
|
|
|
|
.. module:: zlib
|
|
:synopsis: zlib decompression
|
|
|
|
|see_cpython_module| :mod:`python:zlib`.
|
|
|
|
This module allows to decompress binary data compressed with
|
|
`DEFLATE algorithm <https://en.wikipedia.org/wiki/DEFLATE>`_
|
|
(commonly used in zlib library and gzip archiver). Compression
|
|
is not yet implemented.
|
|
|
|
Functions
|
|
---------
|
|
|
|
.. function:: decompress(data, wbits=0, bufsize=0, /)
|
|
|
|
Return decompressed *data* as bytes. *wbits* is DEFLATE dictionary window
|
|
size used during compression (8-15, the dictionary size is power of 2 of
|
|
that value). Additionally, if value is positive, *data* is assumed to be
|
|
zlib stream (with zlib header). Otherwise, if it's negative, it's assumed
|
|
to be raw DEFLATE stream. *bufsize* parameter is for compatibility with
|
|
CPython and is ignored.
|
|
|
|
.. class:: DecompIO(stream, wbits=0, /)
|
|
|
|
Create a `stream` wrapper which allows transparent decompression of
|
|
compressed data in another *stream*. This allows to process compressed
|
|
streams with data larger than available heap size. In addition to
|
|
values described in :func:`decompress`, *wbits* may take values
|
|
24..31 (16 + 8..15), meaning that input stream has gzip header.

:class: attention
|
|
|
|
This class is MicroPython extension. It's included on provisional
|
|
basis and may be changed considerably or removed in later versions.
