Re: [tw] Re: upgrade.html does still requires an upgrade on each tiddler

['manta' via TiddlyWiki]

Hi,
I was searching around for updating my TW2 to TW 5. Finally I landed here 
and I am posting here only to show you that such an upgrade solution is 
still necessary for old TiddlyWiki Users.
Best regards and many thanks for all your work

[tw] Re: Investigation: Lightboxes in TW?

[@TiddlyTweeter]

Ciao PMario

Good questions. 

Its image centric. I don't really care whether its a floating Lightbox. But 
the aesthetics matter. I need all "furniture" out of the way. And its got 
to be adaptive to screen sizes. 

FYI, the images themselves are all the same size. And they are all 
portrait. That simplifies the aim a bit.

Thanks for the links. I will look.

Best wishes
Josiah

[tw] Re: Investigation: Random -- But Within A Range

['Mark S.' via TiddlyWiki]

I assume you're thinking of using Tobias' random solution ? His is based on 
selecting tiddler titles. Haven't tried it, but assuming you could 
construct a massive filter like:

\define reimage() C:\mypath\fw_$(num)$.jpg
<$list filter="0001 0002 0003 ...etc... 4000 +[random[1]]" variable="num" >
<$image source=<>/>

[tw] A TiddlyWikified Lens on Spreadsheets

[stevesuny]

Folks,


Thanks to some timely help (thanks Mark & Eric), I've developed an 
interpretive lens onto a spreadsheet.


See http://sunypoly-schedule-explorer.tiddlyspot.com/ for an example.



   - Demonstrates import of spreadsheet data into navigable space. One row 
   per case. Each column a field in each case (as defined in xlxs plugin 
   import manager). Every column/field is can be clicked on to create lists of 
   tiddlers matching field value.
   - Start in Classes 
    , and select 
   one. Then select one of the class fields (such as instructor or days, etc.
   - A tiddler is created (see schedule elements template 
   
,
 
   and then rendered using template field value template 
    
to 
   display matching tiddlers.
   - No other code needed.
   - To do
  - clean up names of things like "schedule-elements" and 
  "element-fields" etc.
  - consider writing tiddlers to temp files
   
Comments/ suggestions/ improvements welcome.



//steve.

[tw] Re: Variable for field name in filter

['Mark S.' via TiddlyWiki]

Yeah, you can't use {{!!field-name}} notation to substitute for a filter 
operator suffix AFAIK. Use a macro to concatenate and form your filter 
instead, like:

\define indirect() [field:$(field-name)$[$(field-value)$]]
<$vars field-name={{!!field-name}} field-value={{!!field-value}}>
<$list filter=<> />

[tw] Re: Variable for field name in filter

[stevesuny]

Worked like a charm.

OK, I would never have gotten to figure that out. It seems these generic 
\define sitting on top of macros or templates are very powerful and useful 
addition to the general process of transclusion. 

Thanks for your help! I'll post the results in another thread soon.

[tw] Re: [TW5] parse and style a tiddler content

[paolo b]

Hi  Tony

your suggestion is spot on, in fact I'm using a modified version of Tobias' 
approach.

The only remark I have is that the sort operator in


<$list filter="[indexes[]sort[title]]">

appears to be superfluous, since

$:/core/modules/filters/indexes.js

already forces sorting according to the titles.

This was also a problem for me, since I wanted to list the data tiddler in 
its original order.
I've solved my problem by simply commenting

results.sort();  

at the bottom of  

$:/core/modules/filters/indexes.js 

On a different front, I've also managed to programmatically change the type 
of the tiddler, so that it is temporarily set to data.
So I'm pretty happy now.

Regards

Paolo

[@TiddlyTweeter]

Thanks Mark S.

Yes  to 3999 would work best. I can rename 4000 as . Anything over 
4000 would hit a void.

How should PMario's idea be modified for that?

[tw] Lightweight diagrams (e.g. concept maps)?

[Sean Boyle]

I have seen the plugins which allow tiddlers to represented graphically.  I 
would like to see something lightweight which would simply allow the 
drawing of simple diagrams within a tiddler, something like the railroad 
diagram plugin, possibly using graphiviz syntax.  Has anyone done this?

[tw] Re: [NoteSelf] Bug fixes and (cool) new features

[JWHoneycutt]

How far I've gotten:
   
   - 1) Created a Cloudant account: https://jwhoneycutt.cloudant.com
  - 1A) In Cloudant -> Account -> CORS: Enabled CORS and restricted to 
  specific domain: https://noteself.github.io
   - 2) Open https://noteself.github.io/ in Google Chrome (for some reason 
   people keep saying to start TW5's in Google Chrome and use them in 
   FireFox <#FireFox>)
   - 2A) In the GettingStarted <#GettingStarted> tiddler I change the 
   following entries:

Notebook Name: JWH_NoteSelf

CouchDB <#CouchDB> URL: https://jwhoneycutt.cloudant.com (right?)

Remote database name: JWH_NoteSelf

Page title: JWH_NoteSelf


   - 3) I click on Save Config button - and a popup appears: 
   "noteself.github.io says: Configuration has been changed and saved. It is 
   necessary to reload the window. Are you OK with it?" -> I click OK
   - 4) A "Loading" paints green from left to right for a few seconds, and 
   the red circlecheck icon turns gray. It is next to a new button on the 
   sideBar labelled OFFLINE (In the silent video this converts to a cloudcheck 
   icon)
   - 5) I save a new tiddler as a test and Chrome creates a file 
   "tiddlywiki (5).html" in my downloads folder
   - 6) I move this file from Downloads folder to Dropbox/TW5 folder and 
   rename it JWH_NoteSelf.html
   - 7) I drag this newly renamed file to the FireFox <#FireFox> address 
   bar and it fails to load with a big red error box: "Internal JavaScript 
   <#JavaScript> Error, Well, this is embarrassing. It is recommended that 
   you restart TiddlyWiki <#TiddlyWiki> by refreshing your browser -
   ReferenceError <#ReferenceError>: $TPouch is not defined" - since 
   refreshing the address bar doesn't help - I close the tab in FireFox 
   <#FireFox>
   - 8) I open TiddlyDesktop <#TiddlyDesktop> and "Add a TiddlyWiki 
   <#TiddlyWiki> file": I select Dropbox/TW5/JWH_NoteSelf.html and it 
   doesn't load it, so I close all TW5 files and reload TiddlyDesktop 
   <#TiddlyDesktop>
   - 9) If (happens half the time) TiddlyWiki <#TiddlyWiki> Desktop does 
   load it - when I try to open it - it gives the same "Internal JavaScript 
   <#JavaScript> Error" in a big red box.
   - 10) Same error if I just try to double click JWH_NoteSelf.html in the 
   dropbox folder (set to default open with FireFox <#FireFox>)

Maybe I violated some JavaScript <#JavaScript> convention when I renamed 
the file, or moved it?

D'oh! Very clever Pmario!

That will actually make a number between  and 4999. Perhaps a number 
between  and 3999 would be acceptable? That's actually 4000 distinct 
numbers.

[tw] Transcluding fieldnames into filters

[stevesuny]

given a tiddler with fields field-name=instructor and field-value=Chiang,

<$list filter="[instructor[Chiang]]">
<>


2 
<$list filter="[instructor{!!field-value}]">
<>


3 
<$list filter="[{!!field-name}[Chiang]]">

(I've tried every combination of !! and {{ and [  . I spend so much 
time doing filter syntax

[tw] Re: [TWC] How to delay the execution of a macro or a part of it

[Yakov]

Hello whatever,

today I've read a very nice article about browsers' JS main loop and Web 
Workers [*] and it seems that Web Workers is exactly what you need. Like 
you said, JS is a single-thread, but Web Workers "break this rule": they 
are processed in separate threads and hence don't hang the interface. 
Still, they have their limitations: DOM can't be manipulated from a Web 
Worker. Hence, you should create a Web Worker and set an event handler: 
once the job is done by your Web Worker, you can change DOM. Normally WW 
are used with JS in a separate file, but this can be worked around using 
stuff like

var worker = new Worker( window.URL.createObjectURL( new 
BlobBuilder().append( "onmessage = function(e) { postMessage('hello 
habrahabr'); }" ).getBlob() ) ); worker.postMessage();

Another option is to use setTimeout instead of WW: in this trick JS bits 
(small enough) are executed between other stuff in the event loop and hence 
the interface doesn't hang [**].

Best regards,
Yakov.

[tw] Re: Link to a tiddler named in a field value

[stevesuny]

Eric, this *almost* works, thanks! So close...I can see it working :)

The challenge remains building a link to a tiddler represented by a 
transcluded value of a filtered tiddler.



You had

<$list filter="[tag[schedule-elements]eachsort]">
  <$vars this-value=<>>
  <>: <$link><>

which created a link to the filtered tiddler not the value tiddler.


I changed it to

<$list filter="[tag[schedule-elements]eachsort]">
<$vars this-value=<>>
<>: <>: Link to <$link 
to=<>><>

which doesn't quite work: if <> is "instructor" my link goes to 
{{!!instructor}}

So I must be only one level off on the transclusion...so close!

//steve.

[tw] Re: Investigation: Random -- But Within A Range

[@TiddlyTweeter]

Thanks Mark S.

A query, does "<$list filter="0001 0002 0003 ...etc... 4000 +[random[1]]" 
variable="num" >" mean i'd have to literally enter 4000 numbers? If so, 
that looks like asking for trouble.

Could it not be calculated from a spawned random?

I wasn't actually thinking of using Tobias' solution because it seemed more 
focused on Tiddlers that exist. What I need is only random creation of a 
number between 0001 and 4000 to help create an external file link that is 
transitory.

I don't have time to look at this right now, but the first thing I would

<$wikify name=this-value text=<>> ...

[tw] Re: Investigation: Lightboxes in TW?

[PMario]

Hi TT,

Should it be a lightbox only, or should there be the standard "writer" 
interface too. ... I personally don't like popups and modals. IMO they 
waste screen real estate. Images, videos, .. should be full-screen with 
minimal UI, even in a TW. 

I'm thinking about stuff like these: 

 - https://tympanus.net/Tutorials/CSSMaskTransition/  ... latest browsers 
only ... I love demo2 and 3
 - https://tympanus.net/Tutorials/TiltedContentSlideshow/
 - https://tympanus.net/Development/ScatteredPolaroidsGallery/

The problem with those examples is. You still need perfect images, to make 
the effects shine ;) and for TW we'd need to make everything dynamic. So 
basically implement it from scratch. ... But I like the animations for 
about 20 minutes ;)

So if you want to work with it, I'd use much less bells and whistles. 

have fun!

Ciao PMario

Tx. The three demos at  https://tympanus.net/Tutorials/CSSMaskTransition/ 

  
are superb, even with "You're seeing a fallback because your browser does 
not support CSS Masks." That design won't work, unfortunately for my needs, 
because it fills the screen by clipping. 

The images I want to show should not be clipped. I need a solution that 
optimally fits the image to the viewport.

[tw] Re: Link to a tiddler named in a field value

[stevesuny]

Mark, thanks for the suggestions.

Here's what I'm trying to do (I'll try to explain it in words)(turns out, 
it is rather difficult).

I am using xlsx to import spreadsheet data. Each row becomes a tiddler. 
Each column becomes a field in the tiddlers created by the rows; each cell 
becomes the field value in the tiddler associated with the row.

In my example, I have a spreadsheet 

 in 
which the rows represent a scheduled class at my University for the Fall 
semester. The columns, among others, include the name of the *instructor* and 
the *subject *of the course. The rows are called "elements" in my code.

I have identified the fields (including instructor and subject) and given 
them a common tag (element field).

I am writing a generic template that will run for any tiddler tagged 
element field.

The template is designed to filter all elements, identify each value 
associated with the element field, and create links to tiddlers whose names 
are the values of the identified element field. So, for example, if my 
elements included courses whose subjects were Accounting and English, the 
template for tiddler "Subject" would generate a link to tiddler 
"Accounting" and to tiddler "English"

Once there, another template will generate contents for tiddlers 
"Accounting" and "English" 

In this way, all fields of a tiddler become navigable, and we can view the 
dataspace from the perspective of any of the element fields.

*My challenge remains: how to build  <$link to=<>> <>  for <> where  <> is the value of 
field <> in <*

Does that explain it better?

//steve.

[tw] Re: A TiddlyWikified Lens on Spreadsheets

[@TiddlyTweeter]

Ciao Steve 

Its really impressive in its scope and organisation.

Its a mess as a demo. THERE IS NO REAL CONTENT in anything I could find. 

*What's the point other than proving you can create a skeleton? *

IMO you need content FLESH too to make it real. To show what its all FOR.

Given the vast numbers of things it covers I really don't understand why 
they all lack details. There is NO WAY you could manually enter the data 
needed to fill them unless you got a full-time typist. 

Surely the point would be to POPULATE the end Tiddlers with substantive 
information on import? I do not understand why you are flagging this up 
before that was achieved.

I'm a bit of concretist. x

[tw] TW5 button popup to set a field/index?

[mystikite]

I am attempting to create a button that, when clicked, pops up a <$list> of 
tiddlers w/ a specified set of tags.
on clicking a list item, it sets a field/index in the specified tiddler.

This is a for a spell sheet template for a dnd campaign notebook i am 
making.

I was attemping to adapt from Tobias' popup macros, but i am butchering it 
terribly.

Can someone clue me in on what i'm doing wrong?

\define choose_spell(field:nofield tags:"")
<$set name="state" value=<>>
<$button popup=<> class="pop-btn" 
selectedClass="pop-btn-selected">$field$<$reveal type="popup" 
state=<> class="tc-popup pop-popup" set="$(title)$">

<$linkcatcher  setTo="$field$">

<$list filter="[tag[Spell]$(tags)$]">
<$link to=<> >{{##title}}






\end

Ciao Sean

Drawing what? What kind of diagrams do you need?

There are several logical diagramming plugins. Maybe not so easy to find 
all of them if you unfamiliar. I probably can find them if you need.

I believe there is a well featured Mermaid plugin that does complex flow 
diagrams & Gannt charts. There are also several simple branching hierarchy 
flow chart plugins.

[tw] Re: TW5 button popup to set a field/index?

['Mark S.' via TiddlyWiki]

Maybe instead of whatever the linkcatcher is suppose to do (sure would be 
nice if someone completed it's documentation with an example or two), maybe 
generate a list of pop-up buttons. Like:

\define choose_spell(field:nofield tags:"")
<$button popup="$:/listpop">Pop up list

<$reveal type="popup" state="$:/listpop">
<$list filter="[tag[$tags$]]">

<$button set="!!$field$" setTo="YES"><$view field="title"/>





\end

<>


In your example, I couldn't figure out what you wanted set to what. So 
these buttons just put a text value "YES" in the "stuff" field of the 
tiddler that is clicked on. If you want the generated buttons to look like 
links, I think you just add some classes to them.

In your example you were using {{##myfield}} at the bottom which I didn't 
understand because ## is text reference to a data dictionary entry. You 
can't be referring to a data dictionary (AFAIK) that is the same tiddler 
that you are currently in. So ... are you trying to pull from a data 
dictionary somewhere?

Good luck!
Mark

Thanks for sharing that, I am really impressed. I will look into your 
method in more detail as I think this method may be key a number of ways to 
handle data in tiddly wiki.  I see the data is in the relationships between 
a large number of "objects".

Of course over the internet it is quite slow and that's in my Firefox with 
dom.max_script_run_time in about:config up from 10 as high as 80 Now, yet I 
still get timeouts.

Perhaps you could introduce a feature to display the instances grouped by N 
prefix characters such as 
Rooms by 1st letter/number
Classes by first 2-3 letters
Instructor by first letter

If handled correctly they will not need to be rendered until you open a sub 
group and thus operate more quickly and the amount of data would be less 
intimidating.

A practical real world question arises to me and that is how will it 
handled subsequent imports from the same source?, it would be fantastic if 
it could update existing items without removing additional notes applied to 
the different objects (I imagine this is already so), and if it could 
identify deletions and flag them it would be very cool, because you would 
be able to build and maintain a database from multiple "as at" time reports.

Great Work
Thanks

[tw] Investigation: Lightboxes in TW?

[@TiddlyTweeter]

This is an initial query about lightboxes in TW.

I am trying to find demos of "lightboxes" (foregrounded image viewers) in 
TW that have been made. I have seen one by Tobias Beer that is in the right 
kind of direction, using modals, but its under-featured for what I need.

I have a project I could use them for.  

But before I get to the details I think I need to better know what has been 
done already so I'm not creating unneeded work, or asking redundant 
questions.

So: Do any of you know what has been done and where to find it?

Best wishes
Josiah

[tw] Investigation: Random -- But Within A Range

[@TiddlyTweeter]

Ciao tutti

This is an early query to see if anyone can confirm whether what I will 
need will be possible or not.

If it sounds like it is I can lay out the use case in mode detail.

By way of background, I have a project with multiple (external) images. 
When a visitor comes to the TW online I want them to see ONE randomly 
selected image presented via a modal. 

Important to understand is that *this is NOT a randomly selected Tiddler* 
(which a gizmo by Tobias Beer does well already). 

Rather, the modal initiation should dynamically create a path to a randomly 
selected external graphic file that the modal displays. The range for the 
image is currently "0001" to "4000", with full-file names like: 
"fw3045.jpg".   

(My thinking behind this is to NOT burden the TW with 4,000 tiddlers it 
doesn't need to be a lightweight Lightbox). 

I hope this is clear enough.

Please ask me to clarify if it is not.

Many thanks
Josiah

[tw] Re: [TW5] parse and style a tiddler content

[TonyM]

Paolo,

I may be off track but if you are trying to deal with what are effectively 
data tiddlers with content in the form
word: definition

Then Tobias mentions how to Iterate DataTiddler Indexes
https://tobibeer.github.io/tb5/#Iterate%20DataTiddler%20Indexes

That may contain some useful code

Regards
Tony
