How access tiddler content using macro

[Larys]

Hi,

I'm a bit new to writing macros/plugins and though I have taken a
javascript class, I'm still not sure how to access a specific
tiddler's content.

My goal: Make a macro that takes the text from the tiddler siteTitle
and displays it when you write <<siteTitle>> anywhere on the site --
same with siteSubtitle, respectively.

I read the tutorial on how to create a custom macro here:
http://oldwiki.tiddlywiki.org/wiki/Dev:Custom_Macros
but I still don't know how to access the specific tiddlers "siteTitle"
and "siteSubtitle"

Could anyone give me any pointers, please? Any help would be much
appreciated.

Cheers!
Larys

As an exercise in macro writing, I suppose those would be as good as
any.

However, the functionality you describe is already provided by TWCore
macro:
<<tiddler TiddlerName>
will 'transclude' (aka, embed) content from the named tiddler into the
current one.

var txt=store.getTiddlerText("NameOfTiddler","default value");

If the named tiddler doesn't exist, it returns the indicated default
value (or NULL if no default is provided)

enjoy,

Eric Shulman,

Thank you so much! It works perfectly and just as I needed. I have tried to create plugins and macros but not with much luck, generally. I can do web pages fine on my own but often come into problems when extending others' code...I get easily lost in their work, unfortunately. I do wish there were a Tiddlywiki complete documentation/manual of some sort.

Anyway, thank you again! And another thank you for the amazing plugins you've created over the years! --I've been happily using them for a long time! :)

Cheers!
Larys
