20200803 09:06:20 0500  commented question  SageMath 9.1 for Windows @Emmanual Charpentier: The information in your last comment is a bit inaccurate. There have been SageMath for Windows releases for some time now: https://wiki.sagemath.org/SageWindows I know you know this because you directly referred to it. But it is what is meant by "SageMath for Windows". The fact that it uses Cygwin is a technical detail not relevant to most users (although sometimes good to be aware of for more intermediate users, especially when it comes to understanding how it maps UNIX paths to Windows paths and viceversa). @Masacroso: It shouldn't usually take several months, but right now I'm the only one building the Windows installer releases and I had some setbacks in my ability to build the 9.1 release. Usually it should be out within a week or so of the source release

And it doesn't seem to work for commands like "Python: Start REPL". I need to reverse engineer how the Python extension searches for activate scripts, such as when it activates virtualenvs and conda envs, and see if the same mechanism can be used to load a sageenv. This issue also seems to be a problem: https://github.com/microsoft/vscodep... It might be best for a Sage environment to change the default shell to the bash that comes with Sage, but I don't know how to do that yet. Still figuring out how to configure VSCode and some of it is very confusing...

MinTTY is just a terminal emulator that is included in Cygwin, and is also the terminal emulator used by default when running Sage for Windows.

20200131 11:09:29 0500  commented answer  Sagemath and Vscode Well done. Shame about the patch to tornado; I don't see another way around it until/unless it's fixed upstream. One thing I'm a bit confused by: You seem to mention that VSCode comes with its own Python into which you can install Jupyter Notebook, and indeed you mention pip installing Jupyter. But then you say you're running the Jupyter Notebook that comes with Sage, so the previous copy of notebook is never actually used as far as I can tell...unless you're just using Sage Notebook to start the kernel? It would be easier if you copied the sage/kernel.json to somewhere else (not modifying the Sage installation, which is a bit dangerous), and instead installed a copy of that kernel directly into the jupyter notebook you installed on your system kernel. Should work.

20200109 05:10:57 0500  answered a question  Problem importing Sage library in Python script on Windows I'm not sure what you mean exactly by "using Sage in a Python script". You didn't really provide any details. Sage has always traditionally included its own Python interpreter, and so using Sage meant you'd have to run the Python interpreter that comes with Sage (if you're at all familiar with conda as you say, this is a little like having its own conda environment). The folks who've packaged Sage for conda make that a little more transparent, since you can now install sage directly in a conda environment. But either way it's effectively similar.
You will need to run it with the Python interpreter that comes with Sage. If you have additional dependencies, as I wrote, this is a complete Python environment so you can pip install them using Sage's Python.
Because Sage on Windows depends on Cygwin, and there is no official Cygwin target for conda. There could be, and it's something I would like there to be, but it would be a large effort for which there is currently no support.
Not necessarily but it is a little tricky. Search this site for other questions like this one where I explain how to use Sage in PyCharmagain it's not all that different from using a virtualenv; still just a little trickier. If you have any good ideas for how to make this easier I'm all for it.
I noticed also there were some problems with some connection problems with some of the mirrors yesterday. Try just running Sage is a complex beast: Its large set of nonstandard and/or tightlypinned dependencies makes it nontrivial to install and use compared to a normal Python package. People have been working hard for years to make that easier (see, again, your success with conda) but this is not easy. You're welcome to lend a hand if you have any insights.

20200108 11:29:10 0500  commented answer  Should I avoid using unicode in names of variables? @dsejas I agree, it might be good to have a module defining unicode aliases for different globals. It can be made to load on Python 3 only (which is now the default anyways).

20200108 09:18:59 0500  commented question  Rotate a parametric plot As in just, rotating all the pixels of the image, including axes? I'm still not sure why you would want to do that. And also the question is: rotate by an arbitrary amount, or just by 90 degrees? Since rotating images by arbitrary angles means you need some way to deal with clipping. Perhaps you could just add some example images of what results you're trying to obtain...

20200107 10:52:08 0500  commented question  Rotate a parametric plot I don't know Maple so I don't know exactly how to interpret that example. But what do you mean by "rotate a plot"? That could have several different interpretations. In the example you gave in Sage you didn't rotate the plot so much as you rotated a vector field and that plotted the rotated vector field. Do you want to rotate the axes? The entire image?
