Release of bpython 0.14

[Sebastian Ramacher]

Hi all,

I'm very happy to announce the first release of the 0.14 series. After
putting a lot of work into the curtsies frontend, we have decided to
switch the default to point to curtsies. The old frontend is still
available, but it won't see any new feature development. For the full
list of changes, please see the changelog at the end of the mail.


You can fetch the new release from our releases index as usual at:

http://bpython-interpreter.org/releases/

or you can use the PyPI where the package has been uploaded.

If there are any bugs do not hesitate to come tell us on IRC at #bpython
on the Freenode network or through our bugtracker at:

https://github.com/bpython/bpython/issues

Any ideas?

Could you test if https://github.com/bpython/bpython/commit/43e70389badc48be2986a606f8f7b3f2aa29d59b fixes the problem?

Cheers

Yes, thank you very much

[Sebastian Ramacher]

Great. The fix is staged for 0.14-bugfix: https://github.com/bpython/bpython/commits/0.14-bugfix.

Cheers

Nice work, congrats.

I had a minor problem.  When I upgraded my bpython with pip on ubuntu trusty, it did not install the necessary package "blessings."  This resulted in a stack trace on run of bpython, "blessings not found".

This might be a missing dependency of curtsies, not sure, but it needs to be added  somewhere to the list.

I installed the package and it looks to be working well.  Thanks again.

Cheers,

[Sebastian Ramacher]

That's weird. curtsies has a dependency on blessings. Do you happen to have the log available?

Cheers

[Mike]

Yeah it is weird.  But thanks for the idea of looking to the log.  I found an intermittent network problem in it:

  * https://pypi.python.org/simple/blessings/
  Getting page https://pypi.python.org/simple/blessings/
  Could not fetch URL https://pypi.python.org/simple/blessings/: connection error: HTTPSConnectionPool(host='pypi.python.org', port=443): Max retries exceeded with url: /simple/blessings/ (Caused by <class 'socket.gaierror'>: [Errno -2] Name or service not known)
  Will skip URL https://pypi.python.org/simple/blessings/ when looking for download links for blessings
  Could not find any downloads that satisfy the requirement blessings
  ...
  DistributionNotFound: No distributions at all found for blessings

Weird that the other packages worked. 

Thanks,
Mike
