Detect When on Mobile

[Tony Grosinger]

I am trying to create a tiddler which has different content depending on whether on mobile or not. This will be used to alter configuration options.

I noticed that from the console I can view the user agent in navigator.userAgent. Is there any way I can access this information from a macro or widget?

Can't you just do the same ?

Wow, perfect. Thank you.

I have created this snippet which I intended to use for the body of $:/config/EditorTypeMappings/text/vnd.tiddlywiki

<$reveal type="match" state="$:/info/browser/is/android" text="yes">
text
</$reveal>
<$reveal type="nomatch" state="$:/info/browser/is/android" text="yes">
codemirror
</$reveal>

Unfortunately this does not work. The value of the tiddler is exactly correct when you view it normally, but it seems when it is used to actually determine which editor to use it does not actually render the contents first. (I guess the $view widget doesn’t do that by default). Is there another way to accomplish this? I feel like it’s really close, just missing some trick I don’t know about.

Thank you.

I have a feeling the problem I am running into has something to do with this function:

https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/widgets/edit.js#L65-L85

But I am having trouble getting that function to be executed and hit my breakpoint in Chrome developer tools. Developing...

Hi Tony

As you have discovered, tiddlers are only wikified for rendering, and not when their values are used in settings such as configuration. That's why you can't use the list widget within $:/DefaultTiddlers, for instance.

As things stand, I think you'd need a little JS startup module to switch the editor according to the platform. Having said that, the need to disable codemirror on mobile is a widespread problem, and so I wouldn't be averse to fixing it in the core.

Best wishes

Thank you Jeremy. I have moved this question to a Github issue since it seems more like a development task now than a user-configurable option.
