TLDR;
IMO you should describe the functionality, that you want to have a bit
closer. ... I think you want to use an approach that begs for trouble.
- Reasoning -
Your described approach is very error prone and even you or your users (for
sure) will break it by accident.
lets say:
tiddlerOK ... is a tiddler where the macro is ok
tiddlerNok ... macro should not run
Now consider this:
tiddlerNok contains your macro for testing and you call it like this:
tiddlerOK contains the following code:
{{tiddlerNok}}<-- your macro may work
and
{{||tiddlerNok}} <-- macro fails since currentTiddler is still set to
tiddlerOK
The same may happen if you use the <$list> widget with the variable
parameter set to eg: variable="listItem". ... Inside the widget scope
currentTiddler isn't set. ... if the variable assignment is missing
currentTiddler will be set.
Constructions described above are all over the places. .. So I think it
will cause you quite some headache. .. If not immediately it may cause very
hard to find problems in the future.
just some thoughts!

Thanks for the responses. I decided to go with the currentTiddler method,
and since this macro is in javascript,
some poking around in the tiddlywiki source shows that i can reference
this.getvariable("currentTiddler") from inside the macro.
While i can't make this method secure against a determined and
knowledgeable person,
I'm opting for the 'locks only keep the honest people out' approach.

You can check the currentTiddler against an approved list of places, but anything you make can be modified by other people. If you make javascript macros than you can make it harder to get around but there isn't any way to prevent someone who knows a bit about what they are doing from getting around it. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
