appending to external links

[James Anderson]

Hello, 

wondering how i can achieve the following (admittedly contrived) example:

lets say I have a tiddler called Search which contains:

www.google

then in another tiddler i want to use this to create external links to different sites e.g. 

{{Search}}.com -> www.google.com

{{Search}}.co.uk -> www.google.co.uk

{{Search}}.fr -> www.google.fr

the following doesn't work:

<a href={{Search}}.com> link 1</a>

what is the right syntax to achieve this?

Thanks,

James

To construct a parameter value (i.e., the value following the "href=" syntax), you need to use a "filtered transclusion", like this:

<a href={{{ [{Search}addsuffix[.com]]   }}}> link 1</a>

<a href={{{ [{Search}addsuffix[.co.uk]] }}}> link 2</a>

<a href={{{ [{Search}addsuffix[.fr]]    }}}> link 3</a>

Notes:

1) The filtered transclusion syntax is contained within tripled curly braces: {{{ filter }}}

2) The filter syntax itself is contained inside a matched pair of single square brackets: [...]

3) To reference the text content of a tiddler within a filter, use single curly braces: {TiddlerName}

4) To append the desired literal text (i.e., ".com", ".co.uk", etc.) use the addsuffix[...] operator

enjoy,
