That was my initial idea, too

Now I'm just happy to have it somewhere, but I also think it would be 
better to have it in the core. It adds almost no weight.

Maybe at one point we can have it as a core feature, would be great

I do not mind that either - as long as I do not have to install a plugin 
just to get access to this piece of info. As in, I recommend this to core - 
instead of a plugin.

Hi Riz,

IMHO, shouldn't we add them as a part of existing $:/Info tiddlers? That is

If you save a wik html file -i in my case on chromium - a bottom download 
bar appears, that causes a page resize and another dimension change which 
causes it to save again
with auto saving enabled this could be bad

I think it's not too late to change anything but the $:/state tiddlers 
seemed best to me

 yes, great Idea!

The dynaview plugin now adds an option to save viewport dimensions 
dynamically :) !

Hi Simon

Yes, great idea, and a checkbox in the plugin control panel would be nice.

Best wishes

Jeremy.

yes this looks perfect,
should it do this by default or by enabling it through a config tiddler?

Hi Simon

I think the way to do this is as a startup module that listens for viewport 
size changes and then updates a couple of state tiddlers with the values. The 
changes to those tiddlers would then trigger any necessary rerendering via the 
refresh process.

The new DynaView plugin already listens for scroll and resize events, and so it 
might be reasonable to extend it with these features:

https://github.com/Jermolene/TiddlyWiki5/blob/master/plugins/tiddlywiki/dynaview/dynaview.js
 


Best wishes

executing, revealing, listing different things if the viewport width/height 
is lower than x, something else if higher
one can do things in css with vw of media queries, but inside macros or 
widgets I couldn't find a way to get the viewport dimensions

no you're right! it doesn't update. Should I go the widget way?

Could you name some?

I'm a little bit concerned, that a macro won't be always updated. ... Since 
they are only calculated, if rendered. ... But I may be wrong here, without 
tests.
