Hi All, There is a PR https://github.com/numpy/numpy/pull/8096 to vendorize tempita. This removes tempita as a dependency and simplifies some things. Feedback on this step is welcome. One question is whether the package should be renamed to something like `npy_tempita`, as otherwise installed tempita, if any has priority. Thoughts? Chuck
One way to do this is to move to vendorized dependencies into an submodule
of numpy itself (e.g., sklearn.externals.joblib, though maybe even a little
more indirection than that would be valuable to make it clear that it isn't
part of NumPy public API). This would avoid further enlarging the set of
namespaces we use.
In any case, I'm perfectly OK with using something like npy_tempita
internally, too, as long as we can be sure that we're using NumPy's
vendorized version, not whatever version is installed locally. We're not
planning to actually install "npy_tempita" when installing numpy (even for
dev installs), right?

This is the first I am hearing of tempita (looks to be a templating
language). How is it a dependency of numpy? Do I now need tempita in order
to use numpy, or is it a buildtimeonly dependency?

Build time only. The virtue of tempita is that it can be used to generate cython sources. We could adapt one of our current templating scripts to do that also, but that would seem to be more work. Note that tempita is currently included in cython, but the cython folks consider that an implemention detail that should not be depended upon. <snip> Chuck

Ideally, it's packaged in such a way that it's usable for scipy too  at the moment it's used in scipy.sparse via Cython.Tempita + a fallback to system installed tempita if Cython.Tempita is not available (however I'm not sure that fallback is ever exercised). Since scipy needs to support numpy down to 1.8.2, a vendorized copy will not be usable for scipy for quite a while. So, it'd be great to handle it like numpydoc: to have npy_tempita as a small selfcontained package with the repo under the numpy organization and include it via a git submodule. Chuck, do you think tempita would need much in terms of maintenance? To put some money where my mouth is, I can offer to do some legwork for packaging it up. Cheers, Evgeni

It might be better to keep tempita and cythonize together so that the search path works out right. It is also possible that other scripts might be wanted as cythonize is currently restricted to cython files (*.pyx.in, *. pxi.in). There are two other templating scripts in numpy/distutils, and I think f2py has a dependency on one of those. If there is a set of tools that would be common to both scipy and numpy, having them included as a submodule would be a good idea. Chuck

Hmm, I suppose it just depends on where submodule is, so a npy_tempita alone would work fine. There isn't much maintenance needed if you resist the urge to refactor the code. I removed a six dependency, but that is now upstream as well. Chuck

LGTM as is. tools/ seems to be the right place, its outside the numpy package so no one can import it as numpy.something, which is better than a numpy.externals or numpy.vendor submodule.
Evgeni, if you think it a good idea to make a repo for this and use submodules, go ahead with that. I have left out the testing infrastructure at https://github.com/gjhiggins/tempita which runs a sparse set of doctests.
There's a problem with that: it will then not be possible to do: git clone ... python setup.py install # or equivalent We shouldn't force everyone to mess with "git submodule" for this. I suspect a submodule would also break a pip install directly from github. There'll be very few (if any) changes from upstream Tempita, so making a reusable npy_tempita seems premature. Cheers, Ralf

The only thing in the tools directory included in a source distribution is the swig directory. Tempita is only currently used by the cythonize script also in the tools directory. The search path for the cythonize script is 1) installed modules, 2) modules in same directory, which is why it might be good to rename the module npy_tempita` so that is always the one used. <snip> Chuck
