Update version switcher to set 2.0 as preferred version - #25

@charris can you merge this one?

Well, I didn't expect a silly whitespace fix to cause merge conflicts!? Will look into it, or do you just want to force push @melissawm and then we put it in without things?

I'll update 👍

Should be good to go - thanks @seberg

Thanks! I guess it might now only be the preferred thing anymore, but that is good anyway.

Is it correct that it shows "Choose version" for the stable one?

Hmm this may be pydata/pydata-sphinx-theme#1829? Let me check

Looking at the console for the stable docs I see

Uncaught ReferenceError: $ is not defined
    <anonymous> https://numpy.org/doc/_static/versionwarning.js:13

Not sure if this is interfering with the PyData version switcher. I'll try to debug

stackoverflow says the script is missing a jquery reference, something like

<script language="JavaScript" type="text/javascript" src="/js/jquery-1.2.6.min.js"></script>

And indeed, when I compare the 2.0 directory to the other versions, I see it is missing a _static/jquery.js

Not sure if that fixes the switcher but let's try

Something else is wrong, I don't see a call to load the script from the HTML. I will try rebuilding the docs.

Let me know if you need help, I'll be around.

Something changed with the format of the version string in versions.json, so they no longer match. The generated HTML all needs to be changed

     <script>
         DOCUMENTATION_OPTIONS.theme_version = '0.15.3';
         DOCUMENTATION_OPTIONS.theme_switcher_json_url = 'https://numpy.org/doc/_static/versions.json';
+        DOCUMENTATION_OPTIONS.theme_switcher_version_match = 'doc/2.0';
-        DOCUMENTATION_OPTIONS.theme_switcher_version_match = '2.0';
         DOCUMENTATION_OPTIONS.show_version_warning_banner = false;
         </script>

or the versions.json needs to be changed

     {
         "name": "2.0 (stable)",
-        "version": "doc/2.0",
+        "version": "2.0",
         "url": "https://numpy.org/doc/stable/",
         "preferred": true
     },

Are you rebuilding @mattip or would you like me to do it?
