I have tested your fix with python3 and it works. Thanks.

[sage-devel] OSX: pip build failure. zlib dependancy ?

I have got the log below during a sage build on OSX.
Shouldn't zlib be an order-only dependancy of pip ?

Re: [sage-devel] Proposal : Add pplpy and gmpy2 as standard packages.

[Vincent Klein]

In ticket #23024 we made pplpy and independant package with gmpy2 as return 
types.

As opinion for having pplpy returning Sage's type has also been expressed, 
the goal of this message is to check 
if we globally agree to pass pplpy and gmpy2 as standard packages.

I have find a workaround (without an inplace build)  using the site module 
you can target the temporary directory in a generic way

cd src && sdh_pip_install .

SITE_PKGS="$(python -c "import site; \
print(site.getusersitepackages().replace(site.getuserbase(), ''))")"

PYTHONPATH=$PYTHONPATH:$SAGE_DESTDIR_LOCAL$SITEPKGS

Thanks for your answer.
I don't know exactly why it works with sagenb but doing the same with pplpy 
doesn't work
#spkg-install

cd src && sdh_pip_install .

cd docs
$MAKE html


Result in this :

[sage-devel] Help : best way to compile a package sphinx's documentation during spkg-install

[Vincent Klein]

Hi,

I am looking for a good way  to compile a package sphinx's documentation 
during a spkg-install execution.
After doing a sdh_pip_install the compiled files are still in a temporary 
directory ($SAGE_DESTDIR_LOCAL/lib/python2.7/site-packages), a therefore a 
simple sphinx "make html" will fail to find your package's compiled files.
I am looking for a generic way for the /lib/python2.7/site-packages part. I 
haven't find an environment variable for that (I think this path is 
given/constructed by distutils). 

This question comes from 
ticket https://trac.sagemath.org/ticket/23024#comment:106.

The current workaround we have is doing an "inplace" build before  
generating the documentation 
(https://git.sagemath.org/sage.git/commit/?id=ef8997834f73c34d983260c0ba782041d0966a02)

Any help is welcomed

Vincent K.

You may be right, but it's hard to decide as it's a matter of  personal 
taste (as always with UI design choice). Maybe should we do a poll ?

Yes in my opinion. The animation takes 180 sec to display the whole list. I 
think that's way longer than the average time people stay on the home page.
The result is a inequal exposure because the firsts in the list are the 
most viewed.

"below the fold", you mean under library and search button ? 

Side Note : The package list in the prototype is in alphabetical order, i 
keep in mind to randomize the list if we keep this solution.

Another alternative is to display all the packages in a slow scrolling 
horizontal list ScrollingPackagePrototype.html 

. 
Im not sure if the move is too disturbing for the reader or not.

And a logical design choice for pplpy given ppl return gmp numbers.

[sage-devel] Proposal : Add pplpy and gmpy2 as standard packages.

[Vincent Klein]

Hi!
As stated in sage ticket #23024  we 
propose to replace `sage.libs.ppl` by the standalone pplpy 
.
This require to have pplpy as a standard package. As pplpy use gmpy2 the 
latter should be stantard too.

Do we agree to do this ?

Regards

Vincent K.

[Vincent Klein]

For the actual attached icon, the limit between the background color ( 
Royal Blue ?) and the grey color of "developer trac" text is a little too 
blurry. I would prefer a cleaner color separation to make it more readable.
