Re: [tw5] Re: Edit textbox to append text to another tiddler
@Mat: You're right - I typed out a question but left most of the context in
my head! Apologies! Saq guessed what I wanted.
@Saq: Thank you for the code and the explanation of the else!
It might be worth adding that note about blank vs empty string as inputs to
the next step in the filters documentation.

Re: [tw5] Re: Edit textbox to append text to another tiddler
Hi Saq,
Many thanks for clarification
So the magic is the empty string returned by else[]
Thanks again!

Re: [tw5] Re: Edit textbox to append text to another tiddler
@Mohammad the underyling issue is one that I think we have discussed before
in another context.
TiddlyWiki filters distinguish between no results from a filter step, and
an empty string as a result.
When there is no result from a filter step, like with get[text] on a
non-existent tiddler, the next filter step receives no input and therefore
the entire filter run will have no output. However, by using else[] we
specify an empty string as the input to the next step if the previous step
had returned no result. This allows the addsuffix[] step to return a result.
This is the same reason why we have the is[blank] operator, to distinguish
between no result, and an empty string as a result.

Since you are only appending on the Enter key as opposed to on every
keystroke, you could indeed apply this code via a viewtemplate and append
to the tiddler the textarea field is in, if so desired. The key is that
the
edit-text widget writes to a temp tiddler.

Hello all,
Using Nico's projectify with the excellent quick todo add, has put me
in mind for something similar.
I'd like to have a tiddler with an edit box visible in view mode, and
when I type something in that edit box and press enter, what I've typed
gets *appended* to a tiddler (as I understand, cant be the tiddler Im
using the edit box in), with a timestamp.
I know this will involve a keyboard widget. While I was trying it out
myself, I got stuck trying to append.
Has anyone done anything similar and/or willing to help?
Thanks!
