[tw] Re: Using Macro Substitution as a filter parameter
Got it. How can I pass variable data to a Javascript macro, then?

Hi Alan,
Macro parameters are *not* parsed as WikiText until they are returned to
a WikiText context. They're just inert strings of characters. This means
your JavaScript is receiving strings that start with *{{* and end with
*}}*. Only once the macro call has returned will its result be parsed as
WikiText and the transclusions detected and acted upon.

The $macrocall widget should do what you want. It is supposed to evaluate inputs before passing them to a macro. Alternately you can use set widgets and macros: \define thisMacro() javascriptmacro $(macroinput)$ \end $set name=macroinput value=somevalue thisMacro /$set This should evaluate pass the variable correctly. I have a brief and probably not very clear explanation on my site http://inmysocks.tiddlyspot.com/#Concatenating%20Strings%20-%20What%20Breaks about concatenating strings, but the problem happen for the same reason and are fixed in the same way. -- You received this message because you are subscribed to the Google Groups TiddlyWiki group.

[tw] Re: Using Macro Substitution as a filter parameter
Hi Tobias,
I'm finally getting back to this.
Here's a simple Javascript macro that displays the value of three
parameters and the results of a comparison to a constant:
/**
* Created by afinger on 2/24/2015.
*/
/*
Macro to build search string from section and company parameters
*/
(function(){
/*jslint node: true, browser: true */
/*global $tw: false */
use strict;
/*
Information about this macro
*/
exports.name = build_search_string;
exports.params = [
{name: section, default: Any},
{name: source, default: Any},
{name: text, default: }
];
/*
Run the macro
*/
exports.run = function(section, source, text) {
var foo= | + section + | + source + | + text + |\n + | +
(section == Any ) + | + (source == Any) + | + (text == ) +
|\n
return foo
};
})();
Invoking it from a WikiText macro:
\define ShowResult()
build_search_string {{$:/.af/SearchBy/params!!section_sel}}
{{$:/.af/SearchBy/params!!source_sel}}
{{$:/.af/SearchBy/params!!searchtext}}
\end
{{$:/.af/SearchBy/form}}
ShowResult
It always shows the correct value but the comparison is always false.
If I replace the transclusions with constants, it works correctly. What's
going on?

@Jeremy, (how) can a js macro acces a variable number of parameters?
Best wishes, Tobias.

I mean that the operator section{$:/temp/findby!!section} should only be
applied to the filter if the field value is not Any
I'll try to post an example in the next day or so.

have no clue what the meaning should be. Especially because there is no

P.S. Maybe I know! that part means: Get the tiddler titled
$:/tmp/findby but only if it's field section does not contain Any!?

Thanks, Jed, That's a cool example If you know what the filters will be you can use the select widget to set a field to the entire filter string and use a text reference for the filters.

That works well for one variable. The problem is that I have two: section and sourcedoc so I need to try to get concatenation working.

Thanks for some good ideas! I may be missing it but is there a way to set
the value of a field programmatically? The action-setfield widget only
works inside a button.

$select field='filter_field'
option value='[!is[tag]!is[system]]'Some name/option
option value='[!is[tag]!is[system]]'Another name/option
/$select
/$select
$list filter={{!!filter_field}}
/$list
Where you add an option to the select widget for each filter string.
If you need more flexibility you could have a sequence of selections that
build a string for the filter operators. Like the examples here, but each
selection would set a filter operator instead of part of a url

Does that help?

[tw] Re: Using Macro Substitution as a filter parameter
Hi Tobias, I don't think that's going to work for me as I want to conditionally include entire filter operators in the filter. Depending the content of some fields (Any means no filter), i want to get [!is[tag]!is[system]] [!is[tag]!is[system][field1[value1]] [!is[tag]!is[system]field1[value1]field2[value2]] [!is[tag]!is[system][field2[value2]] etc. There will be at 4 combinations now but I may want to expand that later. Is there a more elegant way to approach this? Alan On Tuesday, January 27, 2015 at 9:17:49 PM UTC-5, Tobias Beer wrote: You (currently) need to use variables in filters like so...
