Call "other" plugin function from macro

[todd.c...@gmail.com]

Hi all,

I'd like to extend the <<list>> macro to display the icons that are
associated with tiddler. The macro <<tiddlerIcons>> is provided by
the TiddlerIconsPlugin. I believe the correct place to add this code
is:

config.macros.list.handler = function(place,macroName,params)
{
var type = params[0] ? params[0] : "all";
var list = document.createElement("ul");
place.appendChild(list);
if(this[type].prompt)
createTiddlyElement(list,"li",null,"listTitle",this[type].prompt);
var results;
if(this[type].handler)
results = this[type].handler(params);
for(var t = 0; t < results.length; t++) {
var li = document.createElement("li");
list.appendChild(li);
createTiddlyLink(li,typeof results[t] == "string" ? results[t] :
results[t].title,true);

// ***** START MY CODE *****
if(typeof results[t] == "string") {
tiddlerIcons("=" + results[t]);
}
// ***** END MY CODE *****
}
};

this causes the error: Error while executing macro <<list>>:
TypeError: tiddlerIcons is not a function

How do I call a plugin function from another macro?

Thanks,

Todd

Try this:

if (config.macros.tiddlerIcons)

config.macros.tiddlerIcons.handler(place,"tiddlerIcons","="+results[t]);

Note use of conditional to ensure that the function is NOT called if
it is not defined, e.g., if TiddlerIconsPlugin isn't installed (or has
been disabled via the 'systemConfigDisable' tag).

enjoy,

Thanks!

One change:

config.macros.tiddlerIcons.handler(place,"tiddlerIcons",
["="+results[t]]);

since params is an array.

oops! :-)

I found two more hints:

In the list handler function, use "li" as the place to put the icons
after the tidder title:

config.macros.tiddlerIcons.handler(li,"tiddlerIcons",
["="+results[t]]);


In the tiddlerIcon handler function, add a space to the front of the
first icon:

if (this.map[tags[t]]) imgs.push(img.format(this.map[tags[t]]));
wikify(&quot;&amp;nbsp;&quot; +
imgs.join(&quot;&amp;nbsp;&quot;),place);

Instead of changing the handler, you can just use wikify() to directly
render a leading space into the 'li' element, prior to invoking the
handler, like this:

wikify("&nbsp;",li);

config.macros.tiddlerIcons.handler(li,"tiddlerIcons",
["="+results[t]]);
