Since Last post lots of things happend, I had 2 pull requests on github to fix some typos on previous posts (now updated). We had yet another Jupyter/IPython developper meeting in Berkeley. By the way, part of IPython will be renamed Jupyter. See Fernando Perez Slides and Talk. I got my PhD on my spare time when not workin on IPython. Went to EuroSciPy, hacked in London In Bloomberg Headquarters for a week-end organized by BloomberLab, got a Post Doc at Berkeley BIDS under the direction of above cited IPython BDFL and is about to move almost 9000 km from my current location to spen a year working on improving your everyday scientific workflow from the West of United-States, I think that's not too bad.
Since I got a little more time than usual to do some python everyday since this is officially my day job I was confronted to a few pyton problems, and also sa some amazing stuff.
Eg, James Powel Ast Expression hack of CPyhton: (original tweet)
>>> e = $(x+y) * w * x >>> e(x = $z+10, w = 20)(30, 40) (×, [(×, [(+, [(+, [40, 10]), 30]), 20]), (+, [40, 10])]) >>> _() 80000
Give you unbound python expression that you can manipulate as you like. Pretty awesome, and would allow some neat meta programming. Woudl be nice if he could release his patch so that we could play with it.
A discussion with Olivier Grisel (sikit-learn) raised the point that a good package to deal with deprecation would be nice. Not just deprecation warning, but a decorator/context manager that takes as parameter the version of the software at which point a feature is removed and warn you that you have soem code you can clean.
Using grep to find deprecation warning don't always work, and sometime you would like a flag to just raise instead of printing a deprecation warning, or even do nothing when you are developpin aginst dev library.
Jupyter/IPython 3.0 is on its way. Slowly, we are late as usual.Recap will come at the right time.
I am working on integratin with Google Drive, and will try to add real-time synchronisation to Jupyter 1.0/IPython 4.0. IWe plan on addin other Operational Transform library backend, but workin on Google drive first got me my post doc. (Yes Google signed a Check to UC Berkeley)
Of course new project mean more packagin, and as you all know Python packaging is painfull. Especially when starting a new project you need to get all the basic files...etc.
Of course you can use project like audrayr/cookiecutter, but the you stil have the hassle to :
- set up the GitHub repository,
- Find a name
- Hook Travis-CI find the annoyin setting that let you trigger build.
- Hook up Readthedoc,
- ... 
- And so on and so forth
 add everything that every project should do.
I stronly believe that intelligence shoudl be in the package-manager, not the packager, and my few experiences with julia
Pgk, and a small adventure with nodejs
npm convinced me that there is really something wrong with Python packagin.
I'm not for a complete rewrite of it, and I completly understand the need for really custom setup script, but the complexity just to create a python package is too high. SO as a week-end hack introducing...
So yes I know that cookiecutter as pre- and post- hooks that might allow you to do that, but that's not the point. I just want a (few) simple command I can remember and which can do most of the heavy liftin for me.
I shamelessly call it
PipCreate, because I hope that at some point in the future you will be able to just do a
$pip create to enerate a new package.
So to work beyond dependencies, it just need a GitHub Private token (and maybe that you once loin to TravisCI, but haven't tested). The best thin is, if you don't have github token availlble, it will even open the browser for you at the right page. Here are teh step:
$ python3 -m pipcreate # need to create a real executable in future
Now either it grabs the github token from your keychain, or ask you for it and then does all the rest for you:
$ python3 -m pipcreate will use target dir /Users/bussonniermatthias/eraseme Comparing "SoftLilly" to other existing package name...

It finishes up by openin travis on the test page after a push so that you can see the first test passin after a few seconds.
Hope that will give you soem ideas and patch welcomes.
