Hello,
Here I am again confused about saving filters. This happens to me from time
to time, more or less every time I have to deal with save filters: they're
confusing, they're not very documented and they are very different and
similar at the same time to each other.
My question today is about the difference between two filters, one is
$:/core/save/empty
and the other is $:/editions/tw5.com/download-empty. Below you can see the
respective contents:
title: $:/core/save/empty
\define saveTiddlerFilter()
[is[system]] -[prefix[$:/state/popup/]] -[[$:/boot/boot.css]] -[type[
application/javascript]library[yes]] -[[$:/boot/boot.js]] -[[$:/boot/
bootprefix.js]] +[sort[title]]
\end
{{$:/core/templates/tiddlywiki5.html}
title: $:/editions/tw5.com/download-empty
\define saveTiddlerFilter()
[[$:/core]] [[$:/isEncrypted]] [[$:/themes/tiddlywiki/snowwhite]]
[[$:/themes/tiddlywiki/vanilla]] -[[$:/boot/boot.css]]
-[type[application/javascript]library[yes]] -[[$:/boot/boot.js]]
-[[$:/boot/bootprefix.js]] +[sort[title]]
\end
\define savingEmpty()
yes
\end
{{$:/core/templates/tiddlywiki5.html}}
>From the title, I understand that both are intended to generate an empty
tiddlywiki, but that is all that I can understand. The first just takes
care of including system tiddlers and removing the ones that are hardcoded
at the template, while the second just includes core, a couple of temes and
the same exclusions. What is the reason of this difference ?
I have also discovered (the hard way) that the second one (download empty)
totally ignores the plugins defined at tiddlywiki.info. This made me think
that the second is not suitable for nodejs wiki generation, and is only
meant to be used when you download the wiki from the browser. I don't
understand why are they so different, if someone could explain me it a bit
more.
Also I don't understand the role of the savingEmpty macro. Why the first
one does not include this macro if it is meant to generate an empty wiki ?
What does that macro do exactly ?
Thanks in advance
