Is Numexpr 3 going to be released?

[beojan]

The numexpr-3.0 branch hasn't been updated in a year. Is it still going to be released, or is it abandoned?

I think it's fair to say that work is suspended for now. With work I already do about 100 % the programming I can tolerate. If my work situation changed, then I would probably have the motivation and time to work on it again.

Would you happen to have a task list you would like to see for the 3.0 release? I completely understand having enough work at work, but if you're up to just reviewing PRs this could become a community effort with maybe a project board to organize it. This is easily one of my favorite libraries so it would be nice to help push it forward.

I feel the big issue is to avoid regressions. So the two big items there are string/unicode support, and adding back in reductions.

Probably additionally, I would like to be able to map np.* to the appropriate NumExpr function. This would make it relatively easy to create a decorator that "numexperized" a function.

Looks like some effort has been done lately?

[robbmcleod]

It's on my mind, unfortunately I've been very busy with work lately.

Does that mean that installation of numexpr3 is still not able? I tried these approaches:

1. pip install numexpr3

   Complete output (5 lines): Traceback (most recent call last): File "", line 1, in File "C:\Users...\pip-install-l563yacf\numexpr3\setup.py", line 32, in with open( 'doc/version.py', 'w' ) as fh: FileNotFoundError: [Errno 2] No such file or directory: 'doc/version.py'

2. Following installation instructions on Introduction to numexpr3:

   building 'numexpr3.interpreter' extension compiling C sources error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

@loijord If you clone the Github repo you shouldn't have that error with 'doc' directory not being present. Not sure where you've got the source files from?

You also definitely have to have MSVC Build Tools installed at a minimum to compile the C source code.

I have added the doc directory to the distributions with the a6 release on PyPI.
