Saving Tiddlers with Date-Prefixed Filenames in Node.js TiddlyWiki

[syrte]

Hi everyone,

I want to save tiddlers in the latest Node.js TiddlyWiki with filenames that include the creation date, e.g., 2025-11-07-My Note.tid, while keeping the tiddler title unchanged.

I asked GPT for help, but it wasn’t able to provide a working solution. I also searched online but couldn’t find anything. Does anyone know how to do this?

I understand that I should modify $:/config/FileSystemPaths. I tried something like this (and many variants) but it didn’t work:

[is[system]removeprefix[$:/]addprefix[_system/]]
[has[draft.of]addprefix[_draft/]]
[is[image]addprefix[image/]]
[!is[system]!is[image]!has[draft.of]addprefix[get[created]format:date[YYYY-0MM-0DD]]]

Thanks a lot!

These two posts might be helpful. I will check them in details later.

And this post is particularly relavant

I belive the solution from Add creation date to file name - #6 by EricShulman

[!is[system]get[created]] [get[title]lowercase[]split[ ]] +[join[_]]

is very close to what I want.
The problem is how to get 20251107_new_tidder_2.tid instead of 20251107044358937_new_tidder_2.tid

This is almost what I want

[!is[system]get[created]format:date[YYYY-0MM-0DD]] [get[title]] +[join[ ]]

But I still don’t understand why the other filers don’t need get[title] manually, e.g.,

[is[system]removeprefix[$:/]addprefix[_system/]]
[has[draft.of]addprefix[_draft/]]
[is[image]addprefix[image/]]

tiddler titles are the basic unit of tw

filters
eg

[all[]]

return one or more title('s)

the filter for your case is
doing

[ get&format-date ] [get-title] +[join[]]

joining the result of two filters
which returns a new title

afaik

serendipitously i just read

@etardiff

I find it difficult to draw a hard line between title lists and strings: to include more than one string/title in a stored variable, you have to insert spaces (and bounding brackets as needed), thereby converting your list of strings into… a new, longer string. Essentially, a title list only exists as a collection of discrete strings (rather than a single string than can be converted to smaller strings) when it appears in the context of a filter — and a filter like GettingStarted [[Discover TiddlyWiki]] Upgrading is really a shortcut for the series of filter runs [title[GettingStarted]] [title[Discover TiddlyWiki]] [title[Upgrading]].

which is/might be more clearly articulated ! confusion!! on the subject of titles / filters
ect…

… than can be provided by automated means

how insightful!!!
@etardiff thanks!

Tiddler titles are the default output of most filters that work with the set of tiddlers in your wiki, so adding get[title] to the end of a filter string would be redundant. Indeed, get exists to return field values other than the title, as you can see in your filter:

@syrte

[!is[system]get[created]...]

[!is[system]] checks that each input title (typically <<currentTiddler>> in a subfilter, or all[tiddlers] otherwise) is not a system tiddler, and returns any tiddler titles that pass this check unchanged. To get the values of the created field of these tiddlers rather than the title values, we need to add get[created].
