Re: [tw] Re: How to change a Tiddler's property through javascript?
Could you explain - or point to an explanation of - the difference between fetchTiddler and getTiddler, and why one is higher than the other?

[tw] Re: How to change a Tiddler's property through javascript?
I am no programmer, but as far as I understand a higher function is
the one that 'calls' the lower function. The reason for existence of a
higher function is that it might be doing certain things beside the
call, it might be there to provide a consistency in the API
(application programming interface), it might be there for scalability
and future development of the software etc etc.
A getFoo() function might be a part of an API and a user/poweruser/
client-software can rest assured that it will always return object
'foo' when called, even in future versions.
What a getFoo() function does in order to return the Foo object is the
headache of the API developer, so it might be calling fetchFoo(), or
it might be calling digOutFooFromSomewhere(). We need not worry about
it.

Hi FND,
I wondered about this, but to be honest, I'm too ignorant to know what it is
that higher-level is modifying in your sentence (in the grammatical
sense). Could you explain - or point to an explanation of - the difference
between fetchTiddler and getTiddler, and why one is higher than the other?
Thanks!

It's probably better to use the higher-level getTiddler method instead.

Hi passingby, Well, it turns out there are cases of needing to worry about the difference between lower level implementations and higher level ones, since certain TiddlySpace functions are based on high-level implementations (whereas the low level one might fail on its own), e.g. deleteTiddler vs. RemoveTiddler.

I'm trying to create a script that would automatically change a
property of a tiddler when some event happens. For example, I would
like to make it so that if I press a checkbox a certain Tiddler's
modified date would change to today (I'm using CheckBoxPlugin).
Would anyone have any advice?
One way you could go about it is to assign code like the following to
the action of checking the box:
var tid = store.fetchTiddler('your tiddler title');
tid.modified = new Date();
store.saveTiddler(tid.title, tid.title, tid.text, tid.creator,
tid.modified, tid.tags, tid.fields);
This fetches the tiddler object from the tiddlywiki store, changes the
modified date to the current date and time and then saves it.
That should do it. If you need anymore help let us know
