# toxygen_wrapper
|
|
|
|
[ctypes](https://docs.python.org/3/library/ctypes.html)
|
|
wrapping of [Tox](https://tox.chat/) ```libtoxcore```
|
|
<https://github.com/TokTok/c-toxcore> into Python.
|
|
Taken from the ```wrapper``` directory of the now abandoned
|
|
<https://github.com/toxygen-project/toxygen> `next_gen` branch
|
|
by Ingvar.
|
|
|
|
The basics of NGC groups are supported, as well as AV and toxencryptsave.
|
|
There is no coverage of conferences as they are not used in ```toxygen```
|
|
and the list of still unwrapped calls as of Sept. 2022 can be found in
|
|
```tox.c-toxcore.missing```. The code still needs double-checking
|
|
that every call in ```tox.py``` has the right signature, but it runs
|
|
```toxygen``` with apparent issues.
|
|
|
|
It has been tested with UDP and TCP proxy (Tor). It has ***not*** been
|
|
tested on Windows, and there may be some minor breakage, which should be
|
|
easy to fix. There is a good coverage integration testsuite in ```tests```.
|
|
|
|
## Install
|
|
|
|
Put the parent of the wrapper directory on your PYTHONPATH and
|
|
touch a file called `__init__.py` in its parent directory.
|
|
|
|
Then you need a ```libs``` directory beside the `wrapper` directory
|
|
and you need to link your ```libtoxcore.so``` and ```libtoxav.so```
|
|
and ```libtoxencryptsave.so``` into it. Link all 3 filenames
|
|
to ```libtoxcore.so``` if you have only ```libtoxcore.so```
|
|
(which is usually the case if you built ```c-toxcore``` with ```cmake```
|
|
rather than ```autogen/configure```). If you want to be different,
|
|
then just straighten out the filenames in ```libtox.py```.
|
|
|
|
## Prerequisites
|
|
|
|
No prerequisites in Python3.
|
|
|
|
## Other wrappers
|
|
|
|
There are a number of other wrappings into Python of Tox core.
|
|
This one uses [ctypes](https://docs.python.org/3/library/ctypes.html)
|
|
which has its merits - there is no need to recompile anything as with
|
|
Cython - change the Python file and it's done. And you can follow things
|
|
in a Python debugger, or with the utterly stupendous Python feature of
|
|
```gdb`` (```gdb -ex r --args /usr/bin/python3.9 <pyfile>```).
|
|
|
|
CTYPES code can be brittle, segfaulting if you've got things wrong,
|
|
but if your wrapping is right, it is very efficient and easy to work on.
|
|
|
|
Others include:
|
|
|
|
* <https://github.com/TokTok/py-toxcore-c> Cython bindings.
|
|
Incomplete and not really actively supported. Maybe it will get
|
|
worked on in the future, but TokTok seems to be working on
|
|
java, rust, scalla, go, etc. bindings instead.
|
|
No support for NGC groups or toxencryptsave.
|
|
|
|
* <https://github.com/oxij/PyTox>
|
|
forked from https://github.com/aitjcize/PyTox
|
|
by Wei-Ning Huang <aitjcize@gmail.com>.
|
|
Hardcore C wrapping which is not easy to keep up to date.
|
|
No support for NGC or toxencryptsave. Abandonned.
|
|
This was the basis for the TokTok/py-toxcore-c code until recently.
