Hmm. Well IPython seems to work fine with unicode docstrings in when you specify the encoding, in Python files at least... def foo(x): """Añadir 1 al número deseado.""" return x + 1 gives In [1]: import foo File "foo.py", line 2 SyntaxError: Non-ASCII character '\xc3' in file foo.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details but placing the line `# coding=utf-8` at the start of the file gives: In [2]: import foo In [3]: %pdoc foo.foo Class Docstring: Añadir 1 al número deseado. Calling Docstring: x.__call__(...) <==> x(...) So maybe it's a Cython thing? Science is tricky... ;) On Tue, Jan 8, 2013 at 2:14 AM, Stéfan van der Walt <stefan(a)sun.ac.za>wrote: > On Sun, Jan 6, 2013 at 10:35 PM, Juan Nunez-Iglesias <jni.soma(a)gmail.com> > wrote: > >> Not sure--but this also shows that IPython does not handle unicode > >> characters in a docstring correctly! > > > > Huh?

Re: When will 0.8 official be released?

I could do it in the coming weeks, but I have never done it before. Is there any step by step guide? To be honest I'd rather wait to avoid an invalid release... Am Mittwoch, 9.

Unfortunately, I just moved half-way across the country, and I'm getting ready to start a new job, so I don't think I'll have much time to work on this release (at least, not in the next couple of weeks). I'll probably have a little more free time starting in February. Cheers, -Tony

Contribution: circles and hough transform
by François 09 Jan '13

09 Jan '13

Hi, On my spare time, I work on a code to implement a hough transform to detect circles. This is not implemented yet in skimage. Is Skimage interested in this implementation? (I don't want to spend much more time to polish the code if there is no need) If the answer is positive, it can be done in two steps: * add a method to draw circles. The current "circle" method is for disks. We need circles (very easy to write). This is already done, but in pure python. I saw that drawing methods are implemented in cython. I have never used cython before, but it must be easy (I guess). I implemented two methods (Bresenham or midpoint circle and Andres), both are useful I think. * write the hough algorithm for circle. Done for a Quick and dirty usage, but it's not suitable yet for integration (not safe). I would prefer to send one patch per step. Even if I already tackled bugs in some projects, I never done this kind of contribution before ;) François.

I am currently travelling, and was planning on doing a release beginning February when I got back. However, there's no reason I should be the bottleneck, so if any of the other team members feel up to cutting the release earlier I'd encourage them to do so. Tony, Andreas? Stéfan

Hi, I would say it is time to release 0.8 as a lot of new features have been added, as well as a lot of bug fixes have been made. What do others think? I personally don't see any PR, which I would merge before 0.8.
