problem rendering knowls in Notation appendix on local machine

[sklarjk]

The problem is that they won't render. E.g., if you put the environment witthin a environment, and click on the Definition X link in the Notation appendix, an empty knowl opens, if I am using my Desktop on my Windows machine. If I FTP the files over to the PLU server, the knowls do render.

Is this happening while using Chrome? If so that is a known issue that we have thus far chosen to ignore. My loose understanding is that it is a Chrome issue with viewing localhost files. Maybe we Chrome is right though and we should do something to make it feel more secure?

I have this problem with Firefox, routinely.

It did happen in Chrome, but I just tested it and it happens in IE too. I would think this is an issue worth addressing, since students may want to download books on devices to look at in places where they don't have internet access, and since it fails on Chrome, Firefox, and IE :( .

Of course, that's easy for me to say, since I'm not the one who'd be doing the addressing.

Oh, and selfishly, it makes testing my code difficult since I have to FTP knowls and html docs (at a minimum) to PLU to test my code. Unless someone knows of a better way?

MathJax comes from Cloudflare, fonts come from Google, Sage Cell Server is SageMath, Inc, CSS is from AIM, .... No such thing as an offline version.

What you want is the long-rumored EPUB version, which is basically a reflowable PDF without page numbers and margins (ie a bit lame).

Some day a student will make a packaging script to make everything local. But not a priority. Unless that student studies at PLU?

Ah, ok. Learning new stuff every day.

Please add this to the FAQ or whatever beginner document is being written:

Q. My knowls are empty.

A. When viewing the HTML version on your laptop or local computer, do not expect knowls to work. This is a known bug/feature, and there is nothing to be done about it. Think of it this way: the knowl content comes from a server, but on your laptop there is no web server: you are just looking at files.

The following is a dangerous thing to do, so read carefully. You can close Chrome (make sure all instances of Chrome are closed) and then reopen it with a certain security feature disabled which makes this issue go away for me in the only place I experience it: WeBWorK knowls. Rob and Jessica might see if it works for them too in their situations.

I think it's safe to do this if you only view your PTX output this way. When you are ready to go back to regular web browsing, close Chrome (all instances) and reopen it the normal way. Verify your PTX output is back to not behaving well, and then the security setting should be back active.

Windows: from the command line, run chrome --allow-file-access-from-files. Mac/Linux: run open /Applications/Google\ Chrome.app --args --allow-file-access-from-files. Then open the PTX output. I can only try the Mac version of this, and it does make the issue go away for me with WeBWorK knowls.

Will do.
