Summary: micropython mpy-cross distribution
|

=========
|
||||
mpy-cross
|
||||
=========
|
||||
|
||||
mpy-cross is the micropython cross compiler utility, used to pre-compile python files into bytecode suitable for running on your target.
|
||||
|
||||
This project compiles mpy-cross for windows, linux and macos and distributes them in python wheels for easy installation on development pc's.
|
||||
|
||||
|
||||
Version
|
||||
-------
|
||||
|
||||
The release version of this package directly corresponds to the micropython release it's built against.
|
||||
|
||||
If a wrapper update is needed for a particular release version, it will be updloaded with a `.postN` version
|
||||
|
||||
Weekly releases build against master should be available at: https://gitlab.com/alelec/mpy_cross/pipelines
|
||||
These will have version numbers that reflect the previous release and the current git hash built against.
|
||||
|
||||
Usage
|
||||
-----
|
||||
mpy-cross can be run in three different ways
|
||||
|
||||
* From python command line ::
|
||||
|
||||
python -m mpy_cross <args>
|
||||
python -m mpy_cross --version
|
||||
|
||||
* From python code ::
|
||||
|
||||
import mpy_cross
|
||||
|
||||
mpy_cross.run(*args, **kwargs)
|
||||
|
||||
import subprocess
|
||||
proc = mpy_cross.run('--version', stdout=subprocess.PIPE)
|
||||
|
||||
where `*args` are arguments passed to mpy-cross, `**kwargs` are arguments to pass to `subprocess.Popen()` internally
|
||||
|
||||
* Standalone ::
|
||||
|
||||
# Print out path to actual mpy-cross exe
|
||||
python -c "import mpy_cross; print(mpy_cross.mpy_cross)"
|
||||
> /home/andrew/.local/share/virtualenvs/mpy_cross-gSGkki0d/lib/python3.5/site-packages/mpy_cross/mpy-cross
|
||||
/home/corona/.local/share/virtualenvs/mpy_cross-gSGkki0d/lib/python3.5/site-packages/mpy_cross/mpy-cross --version
|
||||
|
||||
|
||||
mpy-cross options
|
||||
-----------------
|
||||
::
|
||||
|
||||
usage: mpy-cross [<opts>] [-X <implopt>] <input filename>
|
||||
Options:
|
||||
--version : show version information
|
||||
-o : output file for compiled bytecode (defaults to input with .mpy extension)
|
||||
-s : source filename to embed in the compiled bytecode (defaults to input file)
|
||||
-v : verbose (trace various operations); can be multiple
|
||||
-O[N] : apply bytecode optimizations of level N
|
||||
|
||||
Target specific options:
|
||||
-msmall-int-bits=number : set the maximum bits used to encode a small-int
|
||||
-mno-unicode : don't support unicode in compiled strings
|
||||
-mcache-lookup-bc : cache map lookups in the bytecode
|
||||
-march=<arch> : set architecture for native emitter; x86, x64, armv6, armv7m, armv7em, armv7emsp, armv7emdp, xtensa, xtensawin
|
||||
|
||||
Implementation specific options:
|
||||
emit={bytecode,native,viper} -- set the default code emitter
|
||||
heapsize=<n> -- set the heap size for the GC (default 2097152)

pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes.
|
||||
|
||||
Please take a look at our documentation for how to install and use pip:
|
||||
|
||||
* `Installation`_
|
||||
* `Usage`_
|
||||
|
||||
We release updates regularly, with a new version every 3 months. Find more details in our documentation:
|
||||
|
||||
* `Release notes`_
|
||||
* `Release process`_
|
||||
|
||||
In pip 20.3, we've `made a big improvement to the heart of pip`_; `learn more`_. We want your input, so `sign up for our user experience research studies`_ to help us do it right.
|
||||
|
||||
**Note**: pip 21.0, in January 2021, removed Python 2 support, per pip's `Python 2 support policy`_. Please migrate to Python 3.
|
||||
|
||||
If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms:
|
||||
|
||||
* `Issue tracking`_
|
||||
* `Discourse channel`_
|
||||
* `User IRC`_
|
||||
|
||||
If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms:
|
||||
|
||||
* `GitHub page`_
|
||||
* `Development documentation`_
|
||||
* `Development mailing list`_
|
||||
* `Development IRC`_
