Hi
Happy New Year!
I am trying to conditionally transclude tiddlerA if I am on desktop and tiddlerB if I am on my Android phone
I use RCX on Android to get around the security measures that prevent locally stored webpages including locally stored content (video / audio ) the consequence is that content is served up on http://127.0.0.1:8080 if I am on android which can then be accessed.
If I am on Desktop then video and audio content lie in a subdirectory on local disk one level lower than my main tiddlywiki file.
My existing solution for video (which I was helped with) uses two approaches
-
the poster image for the video thumbnail uses a conditional which detects the tell-tale http://127.0.0.1:8080 if RCX is being used and hence I am on Android.
-
The source for the video simply uses the HTML drop through which makes life a lot simpler as it selects the first video URI it can find and play.
<html><video width='80%' controls preload='none'
poster={{{ [{$:/info/url/protocol}prefix[content]then[http://127.0.0.1:8080/videos/example.jpg]]:else[[videos/example.jpg]] }}}
>
<source src='http://127.0.0.1:8080/videos/example.webm'>
<source src='videos/example.webm'>
Your browser does not support the HTML 5 video tag.
</video></html>
My approach to audio was to create two tiddlers of type audio/mp3 differing only in the additional http://127.0.0.1:8080/ prefix in the URI for the tiddler intended for android.
The stage I am at now is that I have tiddler intended to transclude one of the following tiddlers.
{{TiddlerDesktop}}
{{TiddlerAndroid}}
I just have not yet figured out how to show the appropriate one… in psuedo code it would be something like…
if $:/info/url/protocol}prefix[content]
then
{{TiddlerAndroid}}
else
{{TiddlerDesktop}}
So only one tiddler would be transcluded - although pseudo code the conditional indicated after the ‘if’ works fine - I just need to be able to use it in a manner that works with the conditional transclusions that I have tried to indicate in pseudo code.
Thanks
