Find current tiddle title with a javascript macro -or- regex transform {{!!title}}

[Leon Gomez]

Hello,
I'm trying to find a way to get the current {{!!title}} into an alphanumeric + underscores format variable, so for example "Topic: Foo Bar" would be converted to "topic_foo_bar"

The following works to convert text as wanted:

/*\

title: JavaC1

type: application/javascript

module-type: macro

\*/

(function(){

/*jslint node: true, browser: true */

/*global $tw: false */

"use strict";

exports.name = "JavaC1";

exports.params = [

{ name: "myText" }

];

/*

Run the macro

*/

exports.run = function(myText) {

if( !myText) myText = "all spaces to underscores";

        var myAlphanum = myText.replace(/[^A-Z0-9]+/ig, "_");

var output ="1: [" + myText + "] <br>2: [" + myAlphanum+ "]";

return output;

};

})();

Calling:

<<JavaC1>>

<<JavaC1 "symbols ? disappear ! as # well">>

but I can't find how to make it automatically retrieve {{!!title}} as with normal tiddlywiki macros.

Alternatively, is there any other method to transform/user regex inside regular macros, or easily acquire the title on that format? Thanks

Hi Leon

The usual way to address this would be to pass the tiddler title to the macro call by using the macrocall widget:

<$macrocall $name="JavaC1" myText={{!!title}}/>

That way, the macro can be used with any text, not just the current tiddler title.

Best wishes

Jeremy.
