I think this is quite an interesting problem. I don't have it worked out
yet, but I think it's possible.
If you want to play around with this I suggest you be VERY CAREFUL! because
there is a good chance of getting the wiki into an infinite loop, which
will crash it. Obviously, don't do this with your 'real' wiki.
A tiddler with this code
> \define getsnaptitle()
> $(currentTiddler)$ Snapshot
> \end
>
> <$wikify name="outputter" text={{!!text}} output="html">
>
> <$button>
> <$set name=snaptitle value=<<getsnaptitle>>>
> <$action-sendmessage $message="tm-new-tiddler" title=<<snaptitle>>
> tags="Snapshot" text=<<outputter>>/>
> SNAP
> </$set>
> </$button>
>
> </$wikify>
and tagged with $:/tags/ViewToolbar
<http://127.0.0.1:8081/#%24%3A%2Ftags%2FViewToolbar> will add a (big, ugly)
button to the view toolbar that, when clicked will generate a new tiddler
(in edit mode) which contains the text of the original one, but encoded in
static html.
The reason you need to be careful (afaict) is that, if THAT tiddler is open
anywhere it will try to generate a wikified copy of itself, which will
generate a wikified copy of itself which will.... overflow the stack and
crash your wiki.
I ended up creating the tiddler I needed through an edit text widget in
another tiddler...
<$edit-text tiddler="$:/core/ui/Buttons/snapshot"/>
All a bit hacky and sub-optimal but it might get you going in the right
direction. Obviously it can be neatened up and brought into line with the
other page controls (an icon, ability to show/hide it etc.). Not sure how
we preclude the possibility of a recursive loop (this problem must be
solved elsewhere, right?)
I was trying to get it to save the tiddler after creating it, something
like
<$action-sendmessage $message="tm-save-tiddler" title=<<snaptitle>>/>
But I couldn't get this to work and I'm not sure why.
Regards,
Richard
