Is it possible to customize the permalinks?
Currently, TW generates permalinks from the title of the tiddler, which can get quite ugly. like
https://groktiddlywiki.com/read/#Requirements%20for%20the%20Sample%20Wiki
It also affects SEO and sharability. Though I know, TW as a whole is not web crawler friendly. But URL also affects SEO.
So is it possible to have custom permalinks for tiddlers regardless of title?
This discussion seems relevant
https://groups.google.com/g/tiddlywiki/c/QOzs3CVtosU/m/XpqE0X_QBQAJ
So tiddler titles are like UUID.
One possible workaround is that
set the title to a pretty URL, like sample-wiki-req
Set a custom field like human-title to “Requirements for a Sample Wiki”
modify the view template to show the value of the human-title field as the title instead of the default title field
Need to test this idea though.
There are several ways to do this :
You can use a filter in the url, something like this could work :
https://groktiddlywiki.com/read/#:[{id!!10}]
In the tiddler id, create a field “10” or whatever else and put the name of the tiddler you want to link inside. This way you can create shorter links.
Other examples that all point to the same tiddler:
Using filters, I can transform your link from this :
https://groktiddlywiki.com/read/#Requirements%20for%20the%20Sample%20Wiki
to this :
https://groktiddlywiki.com/read/#:[all[shadows]search:title[Requirements]]
If you dont want to use filters, you can create a custom missing tiddler template, or a custom Story Tiddler Template Filter.
E.g :
In a tiddler with the tag $:/tags/StoryTiddlerTemplateFilter and the field list-before :
[{!!title}is[missing]prefix[/]then[RedirectTemplate]]
Then in RedirectTemplate :
\define close()<$action-sendmessage $message="tm-close-tiddler" $param=<<redirect-title>> />
\define edit()<$action-sendmessage $message="tm-edit-tiddler" $param=<<currentTiddler>> /><<close>>
\define delete()<$action-sendmessage $message="tm-delete-tiddler" $param=<<currentTiddler>> /><<close>>
<$let redirect-title={{!!title}}>
<$tiddler tiddler={{{ [{!!title}removeprefix[/]]:map[all[tiddlers]article{!!title}] }}} >
<$messagecatcher $tm-close-tiddler=<<close>> $tm-edit-tiddler=<<edit>> $tm-delete-tiddler=<<delete>>>
<$transclude tiddler="$:/core/ui/ViewTemplate"/>
</$messagecatcher>
</$tiddler>
</$let>
That way I can link to my tiddler using its article field, without using a filter in the url:
https://demos.tiddlyhost.com/#/a-long-title-made-shorter
redirect.json (1.0 KB)
The neat thing about your idea is that the permalink button works, there is no need for using a message catcher widget, only the title needs to be modified. I already made a template for that :
Caption_instead_of_title_with_character_formatting.json (594 Bytes)
You can use the caption field as your “ugly” title, and the title will be used to set the permalink.
I have looked at this issue before and ultimately realised the easiest way to having a tidy url is to have a simple tiddler name. Once someone arrives in your wiki you can show or do anything you want. In fact if you are going out of your way to capture a link “into a wiki and directly to a tiddler” then we can make use of this fact.
Here is a simple example;
{{Setting a favicon}}
https://tiddlywiki.com/#customise-favicon
https://tiddlywiki.com/#Setting%20a%20favicon
This whole concept can be taken a lot further for example
The user will not know they are in anything but the the alternative tiddler unless they edit it.
It is interesting how the language we adopt can influence how we see things later. Sometimes it throws a light on new things other times it distracts us from new ways. For example what I describe above could be called a shadow tiddler, but this term is already defined as something else.
Finally;
[update] I have developed an “alternative title” and 80% of “tiddler masquerade” solution. I will post elsewhere and link to it sone.
Wow! I was putting off testing the idea, thinking it will take me hours to figure out the required customization of the view template. But you implemented in mere two lines. 
I think we can expand this idea to get rid of Relink plugin. If the title of the tiddler is always a unique number, UUID, then we will not need Relink plugin to perform renaming because the user will not need to edit the title field.
Each tiddler always gets a unique title, which does not need to be renamed. The human-readable title is a caption or some other field, say my-title. When linking tiddlers, you connect via the UUID.
There will be issues, though, because TW is not designed to use the title field this way.
One obvious place where it breaks down is the search box. So you need a custom search field that should use your custom field, my-title instead of searching the’ title’ field.
For my personal wikis I generally use tiddler titles: like-this-one. My tiddler titles are always “all lowercase” and combined with hyphens between every word.
I do use the unilink-plugin alias function to be able to use different tiddler pretty-links for the same tiddler title.
There are several advantages:
Just some thoughts, to be able to use the core permalink function with human-readable-titles.
