Most Wanted 2025

Personally, I wish for some added filter operators to handle JSON array manipulation (like push and pop, for instance)…

(An idea proposed in GitHub issue #7840…)

[IDEA] json operators for array manipulation: insert, remove, push, pop

opened 09:30AM - 15 Nov 23 UTC

**Is your feature request related to a problem? Please describe.** The new [jso…nset operator](https://github.com/Jermolene/TiddlyWiki5/pull/7742) allows modifying an array at a specific index, but doesn't easily allow operations that would change the length of the array: adding or removing an item, for example. In order to insert an item into a JSON array, you'd first have to turn it into a TW-style title list with `jsonget`, then manipulate the list, then do a rather complicated operation to turn that list back into JSON format, then finally use `jsonset:json` to put it back in place. **Describe the solution you'd like** It would be far nicer to have the following operators available: - `jsoninsert` - takes a series of indexes (like `jsonset` does), which must lead to an array and a specific index `i` within that array. The item to be inserted is then placed *before* `i`. (If `i` is equal to the length of the array, then the item gets appended to the end of the array, just like what `jsonpush` below does). Returns the new JSON value with the item inserted. - `jsonpush` - takes a series of indexes which must lead to an array. The item to be inserted is appended to the end of the array. Returns the new JSON value with the item inserted. - `jsonremove` - like `jsoninsert`, but *removes* the item at index `i`. Returns the new JSON array with the item removed. If you need the value of the item, do `jsonget` or `jsonextract` first before doing `jsonremove`. - `jsonpop` - like `jsonpush`, but *removes* the last item of the array. Returns the new JSON array with the item removed. If you need the value of the item, do `jsonget` or `jsonextract` first before doing `jsonremove`. Note that negative indexes (as per https://github.com/Jermolene/TiddlyWiki5/issues/7839) should help here: `[<jsonarray>jsonget[-1]]` would fetch the last item. **Describe alternatives you've considered** Technically all of these can be done already using `jsonget` and `jsonset`, but the filter operations to achieve that result would be quite tedious to write, and rather inefficient to boot. **Additional context** In https://github.com/Jermolene/TiddlyWiki5/pull/7742#issuecomment-1740722105 there was some discussion about whether `jsonpop` should return two results: the removed value, and the resulting list. I think it's best to have `jsonpop` just return a single value, which is the list minus its last item; getting the value of the last item would be done with `jsonget[-1]` first, and the `jsonpop` operation would be a separate step. That would avoid the complication of handling the two return values in a filter run. (You could get at one of them with `nth`, but what would you do with the other one? You'd end up having to store the result in a variable anyway).

I have finished this feature and taken you feedback. Pruning is now live, along with unused palette and theme cutting. And it’s careful to remove keyboard shortcuts for editing as well.

TerryTigre · January 20, 2025, 8:10am

What I am looking for is hiding specific Tiddlers, unless a password for those is given. But the actual need for that is not urgent, as I started 2-3 days ago and need to build many more tiddlers.

I may be able to solve it by making separate wikis for each unlock able feature and require authorization for each wiki separately.

So pruning the visible part is helpful, but it is only half of the solution.

You can use this plugin: Encrypt Tiddler Plugin — Encrypt single tiddlers

Then you can filter out the tiddlers that have a non-empty “encrypted” field

A plugin that provides spreadsheet functionality would be my Most Wanted 2025 feature, something similar to this project SheetsJS

stefan_from_germany · January 23, 2025, 10:17pm

Database functionality

@Scott_Sauyet provided in this post Multi level depending tags? a solution of simple database functions.

It would be a great idea to develop it further and to integrate it as plugin or native function.

JanJo · January 24, 2025, 10:21pm

Hi @LoryMoney, I think an implementation of spreadsheet already exists: http://mathcell.tiddlyspot.com/

Ste_W · January 24, 2025, 10:45pm

There is

GitHub - EvanBalster/TiddlyWikiFormula: Functional Formulas for TiddlyWiki, in the style of Excel and Google Sheets

And

http://mathcell.tiddlyspot.com/

@JanJo you beat me to it!

vuk · January 24, 2025, 11:08pm

I get an empty page when trying to open the demonstration wiki link

Ste_W · January 24, 2025, 11:51pm

Here is the plugin (I downloaded the copy in my wiki)

Download and then import into your wiki.

I want this in TiddlyWiki.

It is a demo how dievelopped the obsidian Excalidraw plugin of Obsidian is by now. Many concepts are very similar to TW like transclusion.
Look at how a prezi-like slideshow can be built at Minute 9

pmario · January 25, 2025, 3:50pm

That’s nice, but already on min 1:20 it tells us that we need a server where we need to send our private data, to get a main feature working. — Sorry I did not look any further.

I would be happy to have a mind-map feature as a library but not megabytes of libraries and probably links to tracking code.

I would be happy to have a mind-map feature as a library

do you mean something different than TiddlyMap?

JanJo · January 25, 2025, 11:02pm

Hi @pmario I think this is a misunderstanding: The OCR-support he mentions there is an obsidian-feature that needs a server in the background, not Excalidraw itself. OCR-Support is a difficult task and I do not know any Web-Canvasses that mange to do this without a backend.
I think, here the autor of the video wants to show how deep Excalidraw is integrated into Obsidian which makes it possible to run obsidian scripts and even obsidian-webservices excalidraw.
In the last months Excalidraw also implemented AI features which need a server but I think taht is optional.

Obsidian either runs as a programm on the PC or in the obsidian cloud - it is their buiseness model to enable people to share parts the things stored in the cloud on the web.

JanJo · January 25, 2025, 11:07pm

Tiddlymap alas has had no development for at least 5 years. The Developper is not even in this forum.
To be up to date it would definitely need more features. But it is a terrible drag to tinker in Tiddlymap because there only is a minified .js version.

And the worst point: We discussed here that the library it depends on - vis.js is no longer in active development.

pmario · January 25, 2025, 11:30pm

The source code is at: GitHub - felixhayashi/TW5-TiddlyMap: Map drawing and topic visualization for your wiki

JanJo · January 25, 2025, 11:38pm

Okay, I was wrong. And if @Flibbles is commiting to the repo as I just saw, that would help me gain confidence. Sorry, for me tiddlymap is a sort of disappointed love.

Flibbles · January 26, 2025, 12:00am

So good news on that front. I’ve gotten tired of supporting tiddlymap for people, so I’ve started development of a replacement using memgraph’s orb visualization library. It will have learned from all the mistakes.

I’ll probably post an early version of it when I can to get feedback on how it’s design should be, but it will be weeks or months, since I’ve got other stuff going on.

pmario · January 26, 2025, 12:05am

I did think about jsmind with some TW specific plugins, that would have been to be written. The code base is relatively straight forward. I would like the data structure to be 2-way compatible with the streams plugin.

Flibbles · January 26, 2025, 12:11am

And TiddlyMap really hasn’t been maintained. I’ve just been doing bug fixes here and there that mostly concern myself than others. As you said, the code base is an absolute pain to work with, being pre-minified and having no testing framework.
