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.

Yes, ``import Tkinter`` works as expected for me. Maybe it doesn't work *in matplotlib,* which I'm not sure how to test. Others may know more about this. A bientôt, Armin.

None of the GUI backends currently work out of the box with PyPy, see for intance this stack overflow question https://stackoverflow.com/questions/43278632/pypy-and-matplotlib-error-in-vi... Someone did make progress with matplotlib and wx-cffi https://pythonfiles.wordpress.com/2017/06/28/making-matplotlib-work-with-pyp... The none-gui backends should work, ie ipython inline or Jupyter notebooks. Matti

Cheers for the suggestons on TKinter and matplotlib - mplcairo is out, since it uses pycairo (as opposed to cairocffi). Wx-CFFI looks interesting, however all the matplotlib tutorials give me errors like the one below, so that is probably out as well for now - I'll definitely keep an eye on it and see it starts working though. $ python pyplot.py /home/stu/.virtualenvs/pypy-nightly-trunk/site-packages/wx/core.py:17: UserWarning: wxPython/wxWidgets release number mismatch warnings.warn("wxPython/wxWidgets release number mismatch") /home/stu/.virtualenvs/pypy-nightly-trunk/site-packages/wx/_core.py:31546: UserWarning: implicit cast from 'unsigned char *' to 'char *' will be forbidden in the future (check that the types are as you expect; use an explicit ffi.cast() if they are correct) clib.Cursor_set_flags(wrapper_lib.get_ptr(self), flags) Traceback (most recent call last): File "pyplot.py", line 38, in <module> import matplotlib.pyplot as plt File "/home/stu/.virtualenvs/pypy-nightly-trunk/site-packages/matplotlib-2.1.0rc1+110.g963f91300.dirty-py2.7-linux-x86_64.egg/matplotlib/pyplot.py", line 113, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "/home/stu/.virtualenvs/pypy-nightly-trunk/site-packages/matplotlib-2.1.0rc1+110.g963f91300.dirty-py2.7-linux-x86_64.egg/matplotlib/backends/__init__.py", line 60, in pylab_setup [backend_name], 0) File "/home/stu/.virtualenvs/pypy-nightly-trunk/site-packages/matplotlib-2.1.0rc1+110.g963f91300.dirty-py2.7-linux-x86_64.egg/matplotlib/backends/backend_wxagg.py", line 12, in <module> from . import backend_wx File "/home/stu/.virtualenvs/pypy-nightly-trunk/site-packages/matplotlib-2.1.0rc1+110.g963f91300.dirty-py2.7-linux-x86_64.egg/matplotlib/backends/backend_wx.py", line 1818 SyntaxError: return outside function On Wednesday, September 13, 2017, 12:53:16 PM GMT+1, Stuart Axon wrote: Hi all, Is TkInter pypy still a thing ?

Here is backend_wx.pyhttps://pastebin.com/0bHs4rY5 from~/.virtualenvs/pypy-nightly-trunk/site-packages/matplotlib-2.1.0rc1+112.g17ec41612.dirty-py2.7-linux-x86_64.egg/matplotlib/backends/backend_wx.py 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: doc "/mnt/data/home/stu/.virtualenvs/pypy-nightly-trunk/bin/pypy" etg/grid.py --cffi --nodoc Traceback (most recent call last): File "etg/grid.py", line 392, in <module> run() File "etg/grid.py", line 387, in run tools.runGenerators(module) File "/tmp/t/wxpython-cffi/etgtools/tweaker_tools.py", line 636, in runGenerators g.generate(module) File "/tmp/t/wxpython-cffi/etgtools/pi_generator.py", line 52, in generate self.generateModule(module, stream) File "/tmp/t/wxpython-cffi/etgtools/pi_generator.py", line 149, in generateModule function(item, stream) File "/tmp/t/wxpython-cffi/etgtools/pi_generator.py", line 365, in generateClass bases = [self.fixWxPrefix(b, True) for b in bases] File "/tmp/t/wxpython-cffi/etgtools/tweaker_tools.py", line 96, in fixWxPrefix self._getCoreTopLevelNames() File "/tmp/t/wxpython-cffi/etgtools/tweaker_tools.py", line 133, in _getCoreTopLevelNames parseTree = ast.parse(text, filename) File "/home/stu/pypy-nightly/trunk/pypy-c-jit-latest-linux64/lib-python/2.7/ast.py", line 37, in parse return compile(source, filename, mode, PyCF_ONLY_AST) File "wx/core.pi", line 27712 def operator==(): I can't paste the whole compile output on pastebin as it is > 512k On Saturday, September 30, 2017, 8:56:48 PM GMT+1, Matti Picus wrote: #yiv9103688383 body p {margin-bottom:0cm;margin-top:0pt;} On 30/09/17 03:32, Stuart Axon via pypy-dev wrote: Cheers for the suggestons on TKinter and matplotlib - mplcairo is out, since it uses pycairo (as opposed to cairocffi).
