Pyenchant does *not* work for Windows 64-bit systems

[Edward K. Ream]

Contrary to a recent assertion, there seems to be no way to get pyenchant
working on Windows 64-bit systems.

See pyenchant issue 42, <https://github.com/rfk/pyenchant/issues/42> and a related
conda issue <https://github.com/conda-forge/staged-recipes/pull/3853>. It
looks like lots of people are unhappy about this, including me.

At present, I am using a 64-bit Anaconda3 system, with python2 and python3
environments. This complicates Leo's distribution problems considerably,
for several reasons:

1. I have no way of spell checking LeoDocs.leo! I suppose I could do the
checking on Linux...

2. I don't see any way of getting pyinstaller to create a distro that
includes pyenchant.

I suppose I could install an Anaconda/miniconda 32-bit system to solve #1.
That might also solve #2, but I'm thinking it may cause further problems
for Matt.

Any thoughts?

I think it may be time to look at nltk <http://www.nltk.org/>, a natural
language tool kit for python.

This stack overflow question
<https://stackoverflow.com/questions/13928155/spell-checker-for-python>
asks how to create a spell checker based on nltk. The answer references this
page <http://norvig.com/spell-correct.html>. I think it may be time to
abandon pyenchant.

I have just created #700: create a spell checker based on nitk
<https://github.com/leo-editor/leo-editor/issues/700>. It has a 5.8
milestone, but it may happen for 5.7b2.

Maybe that was me? I may have assumed the Win64 problems only affected
pyenchant 2.0

​Well, I really don't remember, and it doesn't matter :-)

I had pyenchant 1.6.8 installed. I uninstalled it.

Leo fails to load with this error, when pyenchant is not installed:

I changed to default leoSettings.leo to eliminate any personal settings,
but Leo still did not load unless pyenchant was installed.

​Thanks for this report. I have created #707
<https://github.com/leo-editor/leo-editor/issues/707> for this.​

​I'll fix it immediately.

Imo you did right by reporting this issue in leo-editor. Everyone should
know about it.

Latest commit is not loading Leo for me. It's not a complete crash; I have
a Leo splash screen but nothing after that

​Try fc5567a. The new code catches all exceptions when trying to load ​a
dict.
