Re: [pypy-dev] PyPy2 v5.3.0 released, help us get the word out

[Stuart Axon via pypy-dev]

Awesome work, I ask this every time (on one site or another) - is cpyext 
complete enough to use Gtk3 (gi.repository) yet. ?

 This is the culmination of ~6 months of teamwork to get cpyext to a state 
where it can run lxml, numpy, scipy, matplotlib, 
 It runs, but is slow and maybe buggy.
 We need to create some new momentum around PyPy, to encourage uptake, to get 
more sponsorships, and to get some new contributors, so now is the time to try 
this version out, and show it off to your friends, coworkers, and managers.

[pypy-dev] sysconfig.get_path('include') incorrect in virtualenv

[Stuart Axon via pypy-dev]

If I create a virtualenv:  /mnt/data/home/stu/.virtualenvs/pypy-venv
Then run try and get the include path using sysconfig it is incorrect:
 import sysconfig 
 sysconfig.get_path('include')'/mnt/data/home/stu/local/include' 
It should be:/mnt/data/home/stu/.virtualenvs/pypy-venv/include
or possibly where that symlink points to:/usr/lib/pypy/include

This then affects python-config which means I get stuck trying to compile 
pygobject.

Moved to issue 2392 - I probably need to do a bit more testing on sysconfig of 
the different 
paths:https://bitbucket.org/pypy/pypy/issues/2392/differences-with-sysconfig

[pypy-dev] PyBaseExceptionObject has no member named ‘args’

[Stuart Axon via pypy-dev]

Found this trying to compile pycairo, is it worth opening a bug about? (I 
realise there is CairoCFFI, but they don't have feature parity - OTOH, CFFI 
probably is the way to go eventually).

[pypy-dev] Cocos2D - works for me.

[Stuart Axon via pypy-dev]

Hi,   Today I was trying out Cocos2D in PyPy, it seems work :)
I don't have any of my own projects to try, but all the examples that come with 
it seem to work, I also tried some tutorials which seemed to work as well.

Not sure if I use use it enough to be able to say "it works", but I wasn't able 
to break it,

Hi all,   Is TkInter pypy still a thing ?   I was trying some demos from aubio 
from pypy but they didn't work [1].My first thought was to try and install 
tkinter-pypy but that doens't seem to exist any more.
I'm testing with pypy-nightly trunk on Ubuntu 17.04 64 bit.

Here is backend_wx.pyhttps://pastebin.com/0bHs4rY5

Around line 1818 there is a mix of tabs and spaces, which doesn't seem right.
Also  "class PrintoutWx(wx.Printout):" appears more than once.



I'm using the method from that webpage, the only change is I added "sudo" and 
"-y" to the apt-get line.
I used my script to grab pypy 
nightly:https://gist.github.com/stuaxo/5d4c0363317a875617271a6d424abbba
activated the virtualenv it created for trunk
$ source ~/.virtualenvs/pypy-nightly-trunk/bin/activate

Then ran the script - pointing at the virtualenv$ ./build_wx-cffi.sh 
$VIRTUAL_ENV

I noticed this error when building:

 That seems like a strange syntax error, since backend_wx.py is used in the 
standard matplotlib (non-pypy) which is green on their buildbot.
 
 if you are using the method here
https://pythonfiles.wordpress.com/2017/06/28/making-matplotlib-work-with-pypy/
 perhaps it just needs a bit of tweaking for newer versions of backend_wx
 
 Could you post your backend_wx.py to a pastebin or gist so we can reproduce?

[pypy-dev] Pypy friendly to get pointer enclosed in python object ?

[Stuart Axon via pypy-dev]

PyCairo has a struct like
`    typedef struct { 
|    PyObject_HEAD |
|


|  cairo_t *ctx; |
|


|     PyObject *base; /* base object used to create context, or NULL */ |
|

    } PycairoContext;
`
And a #define that you can use to get pointer to ctx:
`    #define PycairoContext_GET(obj) (((PycairoContext *)(obj))->ctx)`
How can I get hold of the pointer *ctx in Pypy ?

I had a bit of a look at CFFI, but couldn't find anything using structures with 
PyObject_HEAD in them.
