Actually it is very on-topic. Most everyone would at some point want to use 
TW seamlessly with email. And its possible.

I personally think we could do a lot more to illustrate and promote 
"integrations" with email, posting to social networks etc.

...but you'll agree it's interesting.

It is. The method in the video is "insertion" of the content into the

Just FYI I use a couple of *other* methods, which I find less techy. 
The one that works well for HTML email for me is enabled by installing in a 
browser the "Markdown Here" browser extension  (it 
works fine with straight HTML as well as Markdown). 
An example result you can see here, where I posted to GG using it (Gmail & 
GG use the same engine so it works on both) in nice looking HTML ...

[tw5] Re: [Demo] Inspect macro definitions

[clutterstack]

I did some prefiltering and this seems to have sped things up by about a 
factor of 4-5 (counting seconds in my head, using [all[tiddlers+shadows]] 
as input and typing one letter into the search).

 Hi all,

 I was playing with dropdowns and...things...and I built something that 
 I wished I had last summer, and which will help me keep track of current 
 variable and macro definitions/values. 

 A first version to play with is at 
 https://clutterstack.github.io/can-tw/clutterstack-TW5-com/#Inspect%20variable%20and%20macro%20definitions

 It's not perfect, but I'm kind of pleased. Also not documented or 
 packaged.

 I ended up writing two javascript macros to access variables and their 
 properties -- if I could have done this using filters, I'd love to know 
 what I missed! I didn't just want to search tiddlers for "\define" etc, 
 because sometimes I put that stuff in code blocks as content.

 Also, if there was a pre-existing public solution for this, I'd also 
 like to see it. There must be a few out there, at least in private wikis.

 Best,
 Chris

[tw5] Re: Some more thoughts on linking in TW (aliases, display text, and relationship types: Oh My!)

[Joshua Fontany]

If we did add a relationship type to links, it helps to unpack the WikiText 
version of Links into their <$link> widget equivalent.

[[LinkText|CurrentTiddler]] unpacks to the following "parse tree" json in 
the internal javascript
```
{ type: "link", attributes: { to: {type: "string", value: link} }, 
children: [{ type: "text", text: text }
```
which is the equivalent to typing:
```
<$link to="CurrentTiddler"><$text text="LinkText"/>
```

Now, as we want "typed" links to other tiddlers, and probably not to 
external resources (hey, make a tiddler that points there), then we can 
re-use the pattern fro the "extended external link" WikiText, and the 
"extended image" WikiText. It would look something like:

```
[type:relationship[LinkText|CurrentTiddler]]
```
which would then render as
```
{ type: "link", attributes: { to: {type: "string", value: link}, type: 
{type: "string", value: type} }, children: [{ type: "text", text: text }
```
and be the equivalent of typing
```
<$link to="CurrentTiddler" type="relationship"><$text 
text="LinkText"/>
```

So, you could not use referenced (transcluded, macro, variable) data for 
the type in the WikiText version, but you could in the full Widget version.

Something to think about

Best,
Joshua Fontany

[tw5] Re: Idea: typed links

[Joshua Fontany]

That is a really good option.

```
title: !mentioned

<$link to={{!!title}}><$text text={{!!title}}/> <$transclude 
field="mentioned"/>
```

```
title: Alice
mentioned: says HI!

Alice is from Alter-space.
```

```
title: Bob

Bob says hi to Alice, so "{{Alice||!mentioned}}"
```


Unfortunately, this does not generate a "backlink" reference because we are 
using a {{transclusion||template}} to generate the final link widget...

https://tiddlywiki.com/#Hard%20and%20Soft%20Links

A link is soft if it is:

   ...


   - generated by a link widget whose to attribute is a transclusion, macro 
   or variable

Re: [tw5] Re: Two requests for Toggle!

[David Gifford]

Thanks! That did it. I thought I had to change .tc-drop-down, since inspect
element showed that as the css for that drop down.

I looked at the cycle operator. There are not enough examples for me to
draw on. I am not a developer on the level of most developers here. I am
more of a user who has picked up just enough to make me dangerous. I learn
by taking existing snippets and figuring out how they work. And I usually
get significant help here. The rather abstract explanations on
tiddlywiki.com rarely help me. I can see enough to know the cycle operator
is what I probably need.

[tw5] Re: Two requests for Toggle!

[Joshua Fontany]

On the CSS z-index targeting, you want to target the div that is `position: 
sticky`, which looks like it is `.hovercontrols`, so:

.hovercontrols {
z-index: 1000;
}

Should do the trick. Tested in my DevTools in Chrome on your demo wiki and 
it seems to work.

 Hi all

 Yes, you read that right, I finally got off my bum and learned Tinka 
 and created my very first plugin.

 The Toggle! plugin is a sidebar tab that allows you to toggle 
 viewtemplate, edittemplate, sidebar and other visual elements. 

 It has the ability to reduce your tiddlers down to mere boxes of text, 
 with thinner margins, smaller titles, and even reducing or removing the 
 gap 
 between tiddlers. 

 It also has two ways to view backlinks. Don't tell that Stroll guy. Oh 
 wait, that's me.

 Demo and download: https://giffmex.org/gifts/Toggle/toggle.html 

 If you followed my CleanTids experiment, please note: there are some 
 major changes. Also, I totally re-wrote the introductory tiddlers, since I 
 had changed so much. (which are not part of the plugin).

 If you are using CleanTids and want Toggle! instead, first delete the 
 tiddlers listed below from your file. Then add the new Toggle! plugin to 
 your file.

- $:/.giffmex/sidebartabs/Toggle
- $:/.giffmex/ViewTemplate/Backlinks
- $:/.giffmex/ViewTemplate/Transclude
- $:/.giffmex/Stylesheet/CleanTids
- $:/.giffmex/Stylesheet/CleanTidsNoMargin
- $:/.giffmex/Stylesheet/ToggleTab
- $:/core/ui/ListItemTemplate2

 Let me know if you find any glitches. Enjoy. - Dave

Hi Joshua

I couldn't interpret your comments, and since I don't know all the ins and

.tc-drop-down {position:absolute;z-index:+10;} and it did not fix the

[tw5] Re: Two requests for Toggle!

[Joshua Fontany]

Hi,

I really like how this is looking, very customizable. I answered point one 
in the other thread, but wanted to expand here.

On the controls-overlapping bug, you wan to explicitly set a `z-index` for 
the element in question.

https://www.w3schools.com/cssref/pr_pos_z-index.asp
*Note:* z-index only works on *positioned elements* (position: absolute, 
position: relative, position: fixed, or *position: sticky*).

I would use a rather large value, like 1000, as this allows "room" for 
plugin authors to play with z-indexes and you can be fairly confident your 
controls will come out on top.

For the 3-value logic problem with the Gaps stylesheets, I would use the 
new "cycle" filter operator, which acks as a multi-value toggle:

https://tiddlywiki.com/#cycle%20Operator

Best,
Joshua Fontany

The catch: the more menu appears under the other tiddlers! Click the top 
tiddler's more menu to see what I mean.

The class appears to be .tc-drop-down. Anybody have any ideas on how to fix 
that?

[tw5] Re: Athens: a VC backed, open-source Roam competitor

[Soren Bjornstad]

My conclusion 
 is that 
backlinks are not necessary, but they're also very helpful in many 
applications (and really not that hard to do right if you're building a 
notes application). I do think that saying the "thing that Roam got right" 
is bidirectional linking is pretty silly, though, especially when they go 
on to talk about this being the core of a "graph-based" system...have they 
ever heard of directed graphs? Evidence that being able to follow the links 
in both directions is the most important key to building good notes seems 
nonexistent to me.

IMO the key to Roam/TW/other powerful notes systems is (1) *modeling* (ability 
to lay out and relate individual notes however makes sense) and (2) *reuse* 
(not 
limited to just linking between things and transcluding entire chunks of 
text, but getting smaller pieces of text, using templates, etc.). Linking 
does help with both of those things, but you could imagine other ways to 
achieve them.

[tw5] Re: [Demo] Inspect macro definitions

[clutterstack]

For Mohammad: I am still wading through the mess I made, but I made a tab 
for Tiddler Commander you can try here 
.
 
This is *totally not ready for prime time and will probably not stay in 
this wiki *but I'd be interested in your feedback as to how you'd like 
something like this to work.

There are two plugins at the moment, to make this work: "selector" and 
"showmacrodef". One gives me a macro for a dropdown selector. The other 
gives me a JavaScript widget and a JS macro, for displaying a variable's 
definition/value and a sample macrocall (if applicable), respectively, as 
well as a tool that makes a tab for Tiddler Commander to inspect for 
variable definitions within a filtered list of tiddlers. There is a tiddler 
that will do something similar without having Commander installed, but it's 
not finished.

The Commander tab does something like this, starting with the searchfilter 
from the top part of the Commander UI:

You type into the selector and it looks through those tiddlers for lines 
with "\define ", followed by something that contains the user input, 
followed by "(". From that, it rebuilds the macro name on that line. Each 
macro name it deduces from this, it lists in the dropdown as a selection 
option. 

Once you select a macro name, it returns a list of the tiddlers that 
contain a "\define" line for that macro name. Note that it's possible for a 
tiddler to have a line like that, but NOT be defining anything (e.g. within 
a code block). To check, you choose the tiddler with a radio button, and 
the macro gives you a display.

Here's where it checks that there's a macro definition in the selected 
tiddler: it redefines that macro using a set widget, then imports the 
variables from the candidate source tiddler. If the macro now has a 
definition, then that tiddler had a real definition in it, and this is 
displayed using the aforementioned JS widget.

I note that the filter in the dropdown interface is pretty slow. Right now 
it's showing all candidate source tiddlers in the dropdown...maybe not a 
good tradeoff performance- and space-wise.

Any feedback welcome.

Best,
Chris

[tw5] Some more thoughts on linking in TW (aliases, display text, and relationship types: Oh My!)

[dieg...@gmail.com]

Hello all,

I thought again about one of my previous posts, and I thought I'd try 
reposting it and editing it to encourage more conversation/ideas around 
this topic.

In my mind, *linking* is one of the two major pillars of TW 
(searching/filtering being the other - why I think a lot and comment a lot 
about search). If I want to link to a tiddler there are *four* (used to be 
three) issues of concern:

1. what I want to type

   - Aliases provided by the un-link plugin are magical here! A tiddler 
   with "long title of method" can save me many keystrokes (and potential 
   typos!) if I just type the name of the alias.
   - Critically, this is decoupled from where I want the *link to go*, and 
   what I want it to *render as*. I don't ever want to type "a very long 
   title", or if the core also supports uniqueIDs, I don't want to type 
   timestamps. 
   - Something that I think should be incorporated into the core () (or 
   at least with uni-link) is the Edit-Comptext dropdown plugin 
   . This plugin already lets 
   you define custom dropdown templates, so its natural to incorporate the 
   filters uni-link provides. 


2. where I want the link to go

   - If we're not just focusing on aliases for a second, this isn't as 
   straightforward as I initially thought - frequently I want a link to go to 
   a tiddler with a specific title (this is the obvious case).
   - Sometimes I want a link to go to a specific tiddler, *regardless of 
   its title**. *For example, my TW is constantly evolving as my system of 
   knowledge is evolving - I rename things, reorganize, etc *frequently.* If 
   I rename a method, or person, etc. all of my links to this tiddler no 
   longer work 
   - (there have been previous discussions of renaming tiddlers triggering 
  a search/replace). 
  - * The recently introduced relink plugin solves this particular 
  problem! *
  - I am more interested in being able to link to a tiddler by some 
   kind of unique ID (for example, created timestamp, or another field) - *that 
   way, renaming a tiddler's title does not trigger massive textual changes in 
   the rest of my tiddlers*
  - I use version control, so it's a bit annoying when I rename one 
  tiddler, my commit object contains changes to 20 other tiddlers whose 
links 
  to this one tiddler also had to change. 
  - Uni-link address this issue, by introducing a (hopefully) unique 
  field: *aliases*.
  - So now I can link to [[coolMethod|?]] *regardless of the actual 
  title of that tiddler!* This is a wonderful feature!
   

3. what I want the link to render/display as in view mode

   - TW already supports some version of this, as sometimes it's 
   appropriate to render a tiddler's title, other times its caption. I just 
   want to extend this so that the user has more fine-grained control over 
   this. 
   

4. What kind of relationship I want the link to represent

   - Thanks to the illuminating typed links thread 
   , 
   I've come to realize this is also a central concept in linking! 
   - Coupled with the ideas given in the recent "Athens" thread about 
   thinking of your knowledge graph more *formally* as an actual graph, it 
   makes sense to think of the kind of connection you want to represent. 


Link Syntax:
Note: below I introduce some spaces to help with legibility, not paying 
attention to the fact that they actually aren't in the syntax.

Currently, the core supports two link types:

   - [[ link target ]]
   - [[ Display text | link target ]]

Uni-link introduces two more:

   - [[ alias name |?]] - links to a target that has 'alias name' in its 
   aliases field. Note you did *not* specify the target name at all! Only 
   its alias! 
   - [[ alias name |? fieldNameToRender]] - links as above, but displays 
   not the alias name or the target name, but the content of the field given

We see that the last uni-link syntax gives the following:

   - ✅ lets me type a short alias for any target 
   - ✅ allows me to NOT have to specify the target tiddler with a long name
   - ✅ changing the target tiddler name does NOT affect any alias links
   - ✅ lets me easily specify what I want the link to display/render as

The only missing feature (besides the autocomplete given by the 
EditComptext plugin) is specifying the relationship type. 

I have no idea what syntax would "make the most sense" but I can propose 
some: 

   - relationshipType::[[ aliasName |? fieldNameToRender]] - like in Roam?
   - [[ aliasName |? fieldNameToRender | relationshipType]]

I'll let others think of a better syntax given TWs internals. 

I'm anxious to hear others thoughts!

[tw5] Re: Idea: typed links

[si]

@Tones I am struggling to understand exactly what you are suggesting. Are 
you saying that to imitate Soren's example of [[Alice!mention]], you would 
create a link to a totally unique tiddler, say [[1234]], then tag that 
tiddler with "mention", then link from that tiddler to [[Alice]]? So you 
would have a kind of proxy tiddler that represents the "type" of link?

Rather than removing the unwanted tiddler elements, you can *hide* them 
using CSS.  To learn the class names of the elements, you can display the 
tiddler in question and then right-click on the elements in question and 
select "Inspect" (note: the exact menu item text can be somewhat different 
depending upon your browser).

For your stated use-case, the elements are ".tc-subtitle" and 
".tc-tags-wrapper".

Then, assuming the tiddler has a title of "TiddlyWiki CV", you can create a 
tiddler, e.g. "MyCustomStyles", tagged with $:/tags/Stylesheet, containing
[data-tiddler-title="TiddlyWiki CV"] .tc-subtitle,
[data-tiddler-title="TiddlyWiki CV"] .tc-tags-wrapper
   { display:none; }

That's it.

[tw5] ViewTemplate: remove an element?

[Erwan]

Hi everybody,

I'm wondering if there is a simple way *not* to display some elements (such 
as the date and list of tags) when a particular tiddler is rendered? The 
only way I can think of is to modify the system tiddler, but it's not very 
convenient.

Use case: I print my TiddlyWiki CV to a pdf file. I have a single tiddler 
which contains the full content, but the header looks a bit odd in the pdf.

Thanks!

Cheers
Erwan

Thanks a lot Mat for your notes/pointers, I really appreciate it.

Regarding the "4 brackets"; actually I got it from this conversation

it works OK with me, and if I used only 2 brackets, the "enlist" doesn't 
split the input variable.

[tw5] How to embed a tiddler(s) inside a gmail message

[Mat]

This is (1) almost off topic and (2) way too intricate to do a lot...

...but you'll agree it's interesting.

I did NOT try this out but I believe it can be used to send a tiddler, even 
a several, directly in a gmail message.

First you must export your tiddlers into HTML format and open the result in 
a text editor so you see the code. (Unfortunately it contains the FULL TW 
css - discuss here 
). Then do this:

Right. Sometimes they are useful--basically "going back-and-forth". 
But I think the real use cases are quite limited.

IMO, the whole field of "strategies of linkage" is generally conceptually 
messy and rarely explained in an enlightening way.

Just because you can do it isn't any reason FOR doing it.

[tw5] Re: Sequential tiddlers

[scot]

Has anyone considered this plugin. $:/plugins/tobibeer/make 
 
I am not sure whether this plugin is still valid when used with the latest 
release of TW, but it offers a number of examples for numbering tiddlers. 
e.g.

*Zero-pad count to 5 digits:* 
{{{ [[]make[%count%\max:3\pad:5]] }}} 
1 
2 
3 

*No Separator Before Unique Number* 
{{{ [[]make[sep:]] }}} 
make1  

https://tobibeer.github.io/tw5-plugins/#make

Can anyone please confirm whether this plugin will work on new wikis and if 
not, can it be replicated in another way using current macro or widget.

 As I wrote in my first post, there is a pending PR, which tries to 
 achieve something slightly related. 

 I did come up with an implementation that looks like this: 

 <>  

 will output 

 yourName 
 yourName  1
 yourName  2

 and so on

 <>  

 which will output something like this: 

 yourName 
 yourName 0001
 yourName 0002

 and so on. 

 <> 
 results in
 yourName00

 As you can see, there is a little bit of a difference.  The *first 
 *example 
 is there for backwards compatibility. The *second* example is new 
 behaviour and will start with the  as the numbering. 

 What do you think? Would this behaviour be OK for your usecase. 

 @Jermolene .. What do you think.

 A working TEST-wiki to test with will be posted soon!

Tiddlywiki getting a bit of a battering in the comments...yeah it's good

The first time I used Tiddly years ago, the UX never resonated with me so I 
wasn't able to get over the learning curve.

More recently, one of our users gave me a pretty detailed tour of their 
Tiddly, which shares sentiments of the other commenters. Single file is 
great until it's not. Lots of plugins but requires manual config. Needing 
to startup a server to collaborate wasn't great.

What "killer features" do you think Tiddly has?


I don't have time right now...any one want to jump in with the killer?

[tw5] Re: Breadcrubs (tiddlersbar) browser-like funcionality

[Ton Gerner]

Hi Damon,

What strikes me is the tiddlersbar displays behind the tiddlers; normally 
it is the other way around.
It can be caused by leftovers from the old breadcrumbs plugin: look for 
overridden shadow tiddlers 
(Controlpanel > Info > Basics; click the search at 'Number of overridden 
shadow tiddlers).
Look for $:/plugins/tongerner/breadcrumbs/... and 
$:/plugins/tongerner/layout_adjustment/...
Delete all these overridden shadow tiddlers.

Note that the tiddlersbar plugin and the matching layout plugin will have 
overridden shadow tiddlers as well ($:/plugins/tg/...)!

Check if you have the newest versions of the Tiddlersbar plugin (v 0.0.21) 
and Layout tweaks plugin (v 0.5.4) available at 
www.tongerner.nl/TW5/TW5_playground.html. In case of upgrading be sure to 
delete overridden shadow tiddlers of both plugins (if required note down 
adjusted settings).

The position of the tiddlersbar is controlled by the Tiddlerbar settings: 
Left Tiddlersbar and Top Tiddlersbar.

Hope that helps,

Ton

 Hi!

 About the dynamic width of the tabs, shrinking when there are more 
 tabs. I think this can be done with CSS flexbox. Check out the flex-shrink

[tw5] Re: Ran into some macro development subtleties

[Saq Imtiaz]

Re: (1) and splitregexp, use of capture groups isn't officially supported 
in regular expressions in filters with the exception of the new 
search-replace operator. This probably needs to be better documented. 

However what is interesting here is that you report that it works in 
TiddlyDesktop. Was it the same TiddlyWiki file used in FF58 and in 
TiddlyDesktop? Or was the TiddlyDesktop file 5.1.22 or 5.1.23 pre-release?

Late in the 5.1.23 pre-release phase, filters were switched to using a 
linked list implementation instead of an array for performance purposes. I 
wonder if perhaps the new linked list implementation is less tolerant than 
than the old implementation for undefined values, and that there has been a 
regression.


Re: (2) use single, double or triple quotes around arguments. The <<__x__>> 
syntax was introduced precisely for those situations where getting the 
quoting of parameters correct might be tricky.


Re: (3)  One of the important differences between the Set and Vars widgets 
is that:

   -  the Set widget directly supports filters and (used in the filtered 
   item variable assignment form) assigns a title list 
    to the variable (which can hold 
   multiple titles).
   -  However the Vars widget does not directly support filters and using a 
   filtered attribute assignment using the triple brace syntax assigns the 
   first title from the filter results to the variable. To be clear this isn't 
   really down to the Vars widget but rather the way filtered attributes 
   for widgets are evaluated 
   
,
 
   i.e. attribute={{{ filter }}} which always assigns the first title from the 
   filter results.

Hope this helps,
Saq

[Mat]

Instead of 

<$list variable="myList" filter="[enlist]">
Auther of : <>  is {{{[get[auther]]}}}


you don't need a variable

<$list filter="[enlist]">
Auther of :<$link/> or <$view field=title/>  is {{!!auther}}

[tw5] Re: Macro: How convert wikified macro output as a "List"

[Mat]

OK this is just to give some pointers. I did not test your (nor my) code so 
maybe you had good reasons for exactly how you did it and my suggestions 
don't work.

\define prepEnlisting(nlst) 
> $nlst$

Not sure why you're using all those brackets. You can probably write it in 
a single row like:

\define prepEnlisting() [[$(nlst)$]]

\define myBooks(category lang)
> <$list filter="[all[tiddlers]tag[$category$]tag[$lang$]]" variable="macO">
> <$macrocall $name="prepEnlisting"  nlst=<> />
>

Put triple quotes around the filters when there's a chance some item has a 
quote character in its name.

\define myBooks(category lang)
<$list filter="""[all[tiddlers]tag[$category$]tag[$lang$]]""" 
variable="macO">
<>

\end

So the wikifywidget is supposedly very resource demanding so it is to be 
avoided when possible. I'd guess it works with a setwidget:
