[tw] Re: [TW5] Applying nth[] to an explicit list
Hi Eric, Thanks a lot for your answer ! It's much simpler and no need to define a new filter. I would never have imagined defining such a macro (myFilter) without matching "[".

Hi, I've found my error : filter="[explicitnth[2]]" instead of : filter="[explicit[]nth[2]]" The correct code is below : \define myMacro() > one two three > \end > > <$set name="test" filter="[explicitnth[2]]"> > test with variable : <> > > > > > FrD > > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.

[tw] Re: [TW5] Applying nth[] to an explicit list
Hi,
I've tried to solve my problem with a new filter which transforms a string
of space separated values into something suitable for operators like nth[].
I've called it 'explicit'.
Note that I'm not familiar with the internals of filters !
/*\
title: explicit.js
type: application/javascript
module-type: filteroperator
Filter operator for creating explicit input from string
\*/
(function(){
/*jslint node: true, browser: true */
/*global $tw: false */
"use strict";
/*
Export our filter function
*/
exports.explicit = function(source,operator,options) {
var str = operator.operand;
var results = str.split(" ");
return results;
};
})();
So I can use :
<$set name="test" filter="[explicit[one two three]nth[2]]">
test : <>
The result is :
test : two
But if I try to use a variable it doesn't work any more :
\define myMacro()
one two three
\end
<$set name="test" filter="[explicit[]nth[2]]">
test with variable : <>
So , if someone has a clue ..
Thanks in advance
FrD

[tw] Re: [TW5] Applying nth[] to an explicit list
Hi Jed, Thanks for answering ! Sorry I can't get anywhere with your proposal, even when I make some modifications. When thinking about my problem, I came to rephrase it in another way : How can I apply the nth[] operator to an explicit list of tiddlers titles ? (that was the title of the thread !) A filter can be an expression like [tag[test]] and I can apply the operator : [tag[test]]nth[2] But when the filter is an explicit list of tiddlers like one two three, or [[one]] [[two]] [[three]], how do I apply the nth operator to such a list (which is not generated by another operator like list[] or tag[]) ?
