Re: [tw] Save tiddlers on TiddlyServer & querying tiddlers

[Jonathan Muehlstein]

It's working now that I've switched to these files:

https://github.com/Arlen22/TiddlyServer/blob/master/tiddlywiki/datafolder-template.json
https://github.com/Arlen22/TiddlyServer/blob/master/example-settings-simple.json

Thanks for the great tools!

[tw] Re: Save tiddlers on TiddlyServer & querying tiddlers

[Jonathan Muehlstein]

This filter does indeed give an exclusive OR.
I didn't expect the filter syntax to be this powerful in a wiki.

Thank you for clarifying this.

Install this plugin by dragging the tid file to your TW file and install 
the official KaTeX plugin list, then you can write latex within markdown 
tiddlers.

[tw] Re: [TW5] Single executable version of multi-user tiddlywiki, release candidate

[TonyM]

Jed,

Could the user name be retained in cookies like twc.

I would be happy to assist in developing a user management layer.

I have this idea that variouse page view and edit templates and some buttons 
like the edit button could be given an index number from say 1 to 9 which is 
used with the reveil widget greater than test.the idea is the higher the number 
the more is revield. Each user could have a value set 1 to 9 that determins 
what they see such as all elements equal or above.

It need not be enforced, but allow the wiki to be used in different modes from 
apparently read only through to edit shadow tiddlers.

Regards
Tony

[tw] Re: Questions for enabling/disabling-button for plugin tobibeer.github.io/tw5-plugins/#preview

[Evolena]

Instead of disabling the whole plugin, you could try to modify the 
"exclude" filter configuration ($:/plugins/tobibeer/preview/defaults/exclude 

 
by adding/removing [all[tiddlers]]) or the classes for which there is no 
preview ($:/plugins/tobibeer/preview/defaults/not 

 
by adding/removing tc-story-river or even tc-body for example).

[tw] Re: [TW5] Single executable version of multi-user tiddlywiki, release candidate

[Jed Carty]

The story list tiddler isn't saved to the server, otherwise it would force 
everyone connected to the wiki to see the same thing. I am trying to come 
up with a way to all to retain story ordering feature but I don't think 
there is a straight forward way to do it. I think I need to implement the 
authentication and login parts for multiple people before I can make saving 
the story ordering work.

Tony and Xavier,

Thank you for the hints, it is working now!

Next: find out why the "retain story ordering" button in the control button 
respectively [list[$:/StoryList]] as default tiddler does not work.

Good night and best regards,
Thomas

[tw] Re: will D3.js plugin be upgraded to version 4.x ?

[Silverfox]

I have updated http://d3jsv5trial.tiddlyspot.com

I could implement the widget for *Circle packing *(still need to understand 
how to improve with CSS style rather than hardcoding), but I failed, so 
far, to implement *Zoomable circle packing* ( 
https://bl.ocks.org/mbostock/7607535).

I cannot understand why it works when using D3 script in an HTML page, and 
not on the D3 adaptation for TW.

I think that the problem start when we use d3.hierarchy... but I may be 
wrong

when I console.log  this: 

> var root = d3.hierarchy(root) 

.sum(function(d) { return d.size; })

.sort(function(a, b) { return b.value - a.value; })

 
I obtain:



>  








we can see that x, y and r are undefined, but I don't why... and I even 
don't understand how they should be generated

Would that be possible that some variable would need to be initialized just 
when using D3 into TW, and not into regular HTML ?
Any other idea ?

Nicolas

Re: [tw] Re: How to limit the execution of an action to a certain screensize / device

[Jeremy Ruston]

Hi Jan, BurningTreeC,

Just to let you know that 5.1.16 includes the following features that you can 
try out in the prerelease at https://tiddlywiki.com/prerelease 


* The core now reports the browser screen size in $:/info/browser/screen/width 
and $:/info/browser/screenheight
* As BurningTreeC notes, a new feature of the DynaView plugin that reports the 
current viewport size dynamically
* Support for "startup actions": action widgets that are executed at startup — 
see https://tiddlywiki.com/prerelease/#StartupActions 

* Riz’s updates to the reveal widget have landed, too — see 
https://tiddlywiki.com/prerelease/#RevealWidget 


With these features it is possible to build UIs that respond to differences in 
the screen size by hiding and showing features in wikitext, instead of the 
usual approach of CSS media queries. (The main advantage of the wikitext 
approach is performance: features hidden with CSS are still rendered and still 
incur an overhead).

Startup actions also make it easier to reset configuration settings at startup.

Best wishes

Jeremy.

Yes you can use the viewport-thing for that, it's now bundled in the 
dynaview plugin from the prerelease page,
I recommend using that. Just enable saving the viewport dimensions in the 
plugin's settings tab,
then you'll have two tiddlers $:/state/dynaview/viewportdimension/width and 
$:/state/dynaview/viewportdimensions/height whose values update dynamically 
every time the viewport size changes

Then you can make your Buttons like that:

\define compareViewportLow()
<$list 
filter="[{$:/state/DynaView/ViewportDimensions/Width}regexp[^$(lowValue)$$]]">
<$button><$actions when viewport low/><$actions more actions/>

\end
\define compareViewportHigh()
<$list 
filter="[{$:/state/DynaView/ViewportDimensions/Width}regexp[^$(highValue)$$]]">
<$button><$actions when viewport high/>

\end
<$list filter="[list[$:/numbers/viewport-low]]" variable="lowValue">
<>

<$list filter="[list[$:/numbers/viewport-high]]" variable="highValue">
<>


I'm using two tiddlers here that store values from 1 to the breakpoint for 
"viewport low" in the list field of $:/numbers/viewport-low and values from 
the breakpoint for "viewport low + 1" to a high value in the list field of 
$:/numbers/viewport-high

You can get a tiddler with all numbers from 1 to  here: 
http://tiddlytouch.tiddlyspot.com/#%24%3A%2Fplugins%2FBTC%2Ftiddly-touch%2Flists%2Fnumbers

Then you can split the list field at the value you choose for your 
breakpoint and make two tiddlers from it


That's one idea,
The other one is using Riz's version of the reveal widget, which can 
compare values with lt (less than) gt (greater than) and gteq and lteq 
(greater/equal, less/equal)
It could also make it to the next tiddlywiki release, but at the moment 
it's not at the prerelease page as far as I know 

You can find it here: 
https://ibnishak.github.io/Tesseract/pluginsandmacros/index.html#Reveal-Extended%3A%20Adding%20%3C%2C%3E%2C%3C%3D%2C%3E%3D%20types%20to%20reveal%20widget

Using this is easier than my version above - you won't need the two 
number-tiddlers!

Re: [tw] Re: [TW5] Single executable version of multi-user tiddlywiki, release candidate

[Xavier Cazin]

Hi Thomas,

Since 0.0.0.0 is *not* a real computer address, you own computer will keep
both 127.0.0.1 (always true for operations local to it like accesses with a
browser running on the same machine) and its local network address that is
displayed in the "Hello!" tiddler (probably assigned automatically at
connection time, and starting with 192.168).

Assigning 0.0.0.0 to the server is just a convention that says that other
hosts in the same local network are allowed to access the wikis operated by
the server. They will do so using your machine local address (thus
typically http://192.168.x.x:8080).

Best,
Xavier.

Re: [tw] Save tiddlers on TiddlyServer & querying tiddlers

[Jonathan Muehlstein]

A couple more details in case necessary to understand the issue:

I've followed the quick install instructions 
@ https://github.com/Arlen22/TiddlyServer#quick-install and created the 
empty tiddlywiki.info file using "datafolder-template.json"and placed an 
empty "tiddlers" folder next to it. 

My settings are simply the ones found in "example-settings-simple.json" 
copied into settings.json.

The console output is a log of HTTP responses.

*Update*:
As a sanity check I've used the following for the settings and the tiddlers 
autosave now:
https://github.com/Arlen22/TiddlyServer/blob/master/example-settings-simple.json

I assume that the following settings are what make the difference?
"etagWindow": 5,
"allowLocalhost": {
"settings": true,
"mkdir": true,
"upload": true
}

I currently see console output such as:
syncer-server-filesystem: Dispatching 'save' task: $:/StoryList 
 filesystem: Saved file 
/home/ubuntu/workspace/twdata/test-wiki/tiddlers/$__StoryList.tid

Thanks again,
Jonathan

[tw] Re: Questions for enabling/disabling-button for plugin tobibeer.github.io/tw5-plugins/#preview

[Jed Carty]

Plugins that include javascript can't be toggled without reloading the wiki 
so I don't think that a button like you want to use can be done without 
modifying the plugin itself.

[tw] How to limit the execution of an action to a certain screensize / device

[Jan]

Hello everybody, Hi Simon in particular...
I am working on a mobile menu/view for TW (which kan be seen on 
smarties.tiddlyspot.com ).
Therefore I would need a button which works differently on Smartphones 
than on desktops.
O smartphones when clicking a link in the Menu, it shall be closed 
because it would be in the way. On the desktop the menu shall remain.
So far I am doing with two buttons and css which switches their 
visibility. But that is an awfull lot of code.

Is there a way to turn of the with something like reveal.

@Simon: Could your viewport thing do something like this?

Yours Jan
