$(currentTiddler)$ and "Title of new journal tiddlers"

[h0p3]

In 5.1.17, I use the following for Title of new journal tiddlers ($:/config/NewJournal/Title):

YYYY.0MM.0DD - $(currentTiddler)$:

When I upgrade to 5.1.18, it gives me the output:

2018.12.12 - $(currentTiddler)$:

How can I gain the original functionality back?

[Mark S.]

I don't know if it's a bug or a feature, but I notice that now if you use

YYYY <<currentTiddler>>

That it works.

Perhaps the change in 5.1.18 did this ?

Restrict variable substitutions to macros defined with the define pragma

I think perhaps it was fortunate it worked for you before, but marks suggestion was possible always the best way to do it as it makes fewer assumptions, clearly one of which is no longer valid.

Thanks for Highlighting it

Regards

But it wasn't just fortunate -- it's the documented way! So if the change is real and permanent, then the docs need to be updated.

Have fun

Yes they will then !

If I had tried to do this without such documentation, I would have tried <<currentTiddler>> first, but then that is just me.

Thanks Mark

This is indeed the result of a change in v5.1.18:

https://github.com/Jermolene/TiddlyWiki5/commit/35cbb127a3c21b7047517f1eeeff571a420b82ae

The problem was that the set widget was performing the same variable text substitutions as a macro definition. This behaviour was never documented, and was entirely inadvertent.

Meanwhile, it sounds like a behaviour that depended on that bug has been documented.

That puts us in the invidious position of being forced to either break backwards compatibility or to leave the original bug unfixed. To me, the original bug is much worse, and much harder to debug. (I mean that a text substitution that is unexpectedly not performed is much easier to spot than a text substitution that is unexpectedly performed).

Best wishes

Jeremy

Gosh, wish I had known about the SetWidget's super powers ;-)

I suspect only a small percentage of users avail themselves of the formatting features for "new journal here.". The ones that do will be

somewhat techy and may even check the original documentation to see if things have changed.

So ... maybe just a change to the documentation will be sufficient, possibly with a note that a former usage has been removed ??

Thanks for making such a great product!

Thank you all! It doesn't matter anymore, but I have experienced some bugs with $(currentTiddler)$ in 5.1.17; I couldn't figure out a reason for these very rare vowel substitutions ("a" became "4" sometimes). In any case, I am grateful to have a superior tool to replace it.

[TonyM]

Mark,

I cant see the superpower of the set widget you refer to?

Regards

Tony

[Mark S.]

The Set Widget, before 5.1.18, could substitute $(variable)$ like a macro.

OK, maybe a very minor super-power. ;-)

Hi!

What adjustment would it take for my old table of contents to work again in version 5.1.18?

<<toc-selective-expandable "$(currentTitle)$" "sort[title]">>

[Mark S.]

Where are you using this? Offhand, this should work in most places:

<$macrocall $name="toc-selective-expandable" tag=<<currentTiddler>> sort="sort[title]" />

Good luck!

-- Mark

[@magasine]

Very grateful for the quick assistance!

It works perfectly, as before.

[Pit.W.]

Thanks again, works  and solved a major problem
