Windows compatibility

[DancingQuanta]

From the README I was warned that this project will not work on Microsoft Windows but nonetheless I am interested on how far can I go with this on Windows and Cygwin using Windows Anaconda Python

Well, could not install from pip from cygwin, what a bore, below is the traceback.

$ pip install khal
Collecting khal

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\cygwin64\\tmp\\pip-build-gfphe0l0\\khal\\khal/aux.py'

The directory where aux.py was expected to be does not exist when I checked to make sure.

Can anyone hazard any interpretion of this error?
What pip and wheel is doing differently on Windows than expected on other system?
Oh and this error is the same in windows as in cygwin if anyone is wondering.

[geier]

To me it looks like something is wrong with the last path, but khal/aux.py isn't hardcoded anywhere. Sorry, I have no idea about windows & python.
Perhaps try to install from the git repository?

[DancingQuanta]

Couldn't install from git repo because the setuptools-scm could not find
the version of khal. Will post traceback when I see my laptop tonight.

I believe the setup.py is not compatible with Windows.

@DancingQuanta then perhaps we should start there with windows compat.

[DancingQuanta]

Yes, I need to understand what makes this setup.py different from the rest
of apps I have been using. Good start would be to understand what pip is
doing.
Or should I look into setuptools-scm first?

I have tried different ways of installing...

Tried installing via python setup.py install

$ python setup.py install > 1.md

Make sure you're either building from a fully intact git repository or PyPI tarb                                          alls. Most other sources (such as GitHub's tarballs, a git checkout without the                                           .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

Using the advice in the error above, I tried

$ pip install git+https://github.com/pimutils/khal.git#egg=khal

Which gives an error

$ pip install git+https://github.com/pimutils/khal.git#egg=khal

The file aux.py still could not be found despite being in the pip-build-z5zrt049.
However noticing the letters of aux.py, it could be the first file to be called for and did not attempt to check other files before throwing an error on missing aux.py.

[DancingQuanta]

I am trying something today.
First I removed any mention of setuptools-scm so that I can try to install from repo properly.
I ran

python setup.py install

which results in an error of khal/aux.py not existing. The traceback is below

error: can't copy 'khal\aux.py': doesn't exist or not a regular file

Why it is trying to copy that file and to where? sites-packages?

Then I renamed the file to aux.py and tried python setup.py install again.
I got khal installed sucessfully. What is going on? Why is the presence of the aux.py file blocking the installation?
Will see if I can copy aux.py to its final place in site-packages if is that where it is supposed to go

[DancingQuanta]

Just now I tried to rename aux.py to auxi.py and replaced all instances of aux in khal with auxi and ran python setup.py install successfully.
Now the question is, why is the name aux.py python seems to choke on?

[WhyNotHugo]

It would seem that windows does not support a file named aux.py (!?!?!):

https://bugs.launchpad.net/tensortoolbox/+bug/1400505

[WhyNotHugo]

Wow, aux is a restricted filename on windows (regardless of extension), apparently, cruft from the DOS days:

https://blog.onetechnical.com/2006/11/16/forbidden-file-and-folder-names-on-windows/

---

My proposal is to rename aux.py to utils.py, if it's okay with everyone else.

[DancingQuanta]

@hobarrera great find! Renaming the file should fix this.

On otherhand, I should avoid using ikhal on windows as ikhal uses unix specific libraries.

[geier]

nice find! yes, I agree with renaming.

[geier]

done, see 9231796 @geier geier committed a minute ago

[geier]

@DancingQuanta if any more errors occur, please keep reporting them, perhaps we are able to fix them.

[DancingQuanta]

@geier Sure. But I do not understand what is the format for datetime that khal can recognise.
Can you give an example of datetime for use of

khal at DATETIME

[DancingQuanta]

Ah the DATETIME is defined in the khal.conf, I need to remember to use these!

[geier]

yep, error message might need to be improved though. I'll close this, feel free to open new issues.
