What Tiddler the parser is working on?

[David Szego]

Hi, how do I know what Tiddler a wikirule parser script is working on?

I'd like to exclude $:/ system Tiddlers from displaying with my rule's parsing, so I'm looking to just do an If... return. However, I can't seem to find the name of the current Tiddler?

My vast and advanced debugging skills extend to basically this:

exports.init = function(parser) {
alert($tw.wiki.currentTiddler);
    this.parser = parser;
    ...

but whatever I try, I'm only finding "undefined". 

Any hints?

Thanks,
David.

Hi David,

I know this is years later, but this your query was important motivation in my own tracking down of this.

Parsers build a "parse tree" of nodes that describe the thml entities and widgets in it's content, and this is used when a _widget_ calls it's `this.makeChildWidgets();` method.

So, you need to go to the _Widget_ that the parse-tree points to and do your getVariable, getTiddler, etc and debugging in there.

Investigating the Railroad Plugin on tiddlywiki.com finally brought it all together for me.

(Coming soon, vastly improved CSV tiddler handling via a rewritten $csv widget, and hopefully easy csv-> tiddler importing!)

Best,
Joshua Fontany

while examining it, is it possible to customize its colors (in
particular the white node/"text fields" backgrounds) it doesn't apply
inverted system/browser theme like the rest of the wiki does.

Hi A Gloom

while examining it, is it possible to customize its colors (in
particular the white node/"text fields" backgrounds) it doesn't apply
inverted system/browser theme like the rest of the wiki does.

I’ve fixed that here:

Best wishes

Jeremy,

Thank you very much-- always been interested in the railroad diagrams

over in the users group if you want.
