[tw] Re: [TW5] More JavaScript macro questions
Hi Mark,
if I do get your code right you create a "list" of author names without
commas?
In my code I join them together and remove the trailing comma and
whitespace pair with a slice before returning the text. So far this works
for my usecase but yours is way more compact which is nice I guess :)
Thanks a lot for your help and effort I am sure I will ask for more when I
dig deeper in my e-book management plugin.
Cheers
Tristan

[tw] Re: [TW5] More JavaScript macro questions
Hi Tristan,
This was the export part of the code I came up with for testing:
exports.run = function(text) {
var vartext = "[["+text.split(",").join("]] [[")+"]]" ;
return vartext ;
};
Both our approaches probably need something in there to squeeze out spaces
after commas.
Have fun!
Mark

[tw] Re: [TW5] More JavaScript macro questions
Hi Mark,
here is my macro code:
/*\
title: $:/plugins/mirodin/ebooks/linklist.js
type: application/javascript
module-type: macro
\*/
(function() {
"use strict";
/*
List all field values as comma separated list of clickable links.
*/
exports.name = "linklist";
exports.params = [];
/*
Run the macro
*/
exports.run = function(field) {
if (typeof field === "undefined") {
return "''Please pass field.''";
}
var elements = field.split(",");
var result = "";
for (var i = 0; i < elements.length; i++) {
result += "[[" + elements[i] + "]], ";
}
result = result.slice(0, -2);
return result;
};
})();
Thanks for your hint, that works for me too and the whole call is way more
readable.
Cheers
Tristan

[tw] Re: [TW5] More JavaScript macro questions
You might try invoking it like this:
<$macrocall $name="listlinks" text={{!!authors}}/>
Where "text" is whatever you have set up as your parameter variable name.
That seemed to work on my quick test.

[tw] Re: [TW5] More JavaScript macro questions
Hi Tristan,
Your English is great -- the documentation is indeed short and abstract.
I've never had much luck passing things to a javascript macro without using
a <$set> variable. I'm thinking it might be possible to use another
standard macro to wrap the <$set> process.
Could you provide the javascript macro and template for testing purposes?
