Hi Stefano,

Kind Regards, Andreas

Just an update: I've re-compiled, reinstalled and restarted elogd for other reasons and now the corrupted strings are all gone. Everthing looks fine now.

But I never worry when a problem goes away before I could understand it: I'm confident that I will have plenty of time later, when the problem magically re-appears - likely I'll be called on a Friday night :-)

Well, Stefan would need to answer that. But if you are good with C-programming, you might implement it yourself?

There is a way to implement it; but it makes your installation a lot more complicated: you can have two ELOG servers. The first has all logbooks but requires authentification to read any. The second has only the public logbooks, and they are mirrored from the first.

On the right side of "Change password" you should find "Change config file".

But you'll only see this, if the user has admin priviledges defined in the config file: "Admin user = <user>"

Then you can edit the configuration of that logbook. At the top you'll have a button "Change [global]" to edit the global part of the configuration - if you have the relevant priviledges to do so.

This logbook, the forum, provides some javascript code. The code is simply referenced in the footer (Bottom text = <file> | <string>).

<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.6.0/styles/default.min.css"><script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.6.0/highlight.min.js"></script><script>hljs.initHighlightingOnLoad();</script>

There's another example under elog:contributions/39

Cheers, Andreas

Hi Alan,

Hi Stefano,
you could try to html encode the "+" and "-" sign in the option list
Options Half = +x, -x, both
Allow HTML = 1

But of course then you would need to change all existing entries.

It is just an idea; I did not try this out, it might not work anyway.

Cheers
Andreas

Hi Stefano,
I've tested it: it does not work.
Neither in edit nor in list view the HTML encoded characters show correctly.
Only in the "Quick filter" menu they show as they should!
But then selecting them in the quick filter will not find any entries :-(

So the short answer: 
avoid characters with a special meaning for regular-expressions in attribute values, in particular if you want to use quick filters.

Cheers
Andreas
