The ParameterParser is used in several places in TiddlyWiki:
|
||
|
|
* to process the StartupParameters after the '#' in a TiddlyWiki URL
|
||
|
|
* to process the DefaultTiddlers list
|
||
|
|
* to process the parameters to Macros
|
||
|
|
* to process tag lists when editing a tiddler
|
||
|
|
It supports a list of parameters each of the form "name:value". For example:
|
||
|
|
{{{
|
||
|
|
name:John location:"Isle of Wight" [[dietary needs]]:none really:'yes, really'
|
||
|
|
}}}
|
||
|
|
Names and values that need to contain spaces may be quoted with single- or double-quotes or double-square brackets. The parser is generally tolerant of additional spaces.
|
||
|
|
|
||
|
|
When processing macro parameters, names and values may also be quoted with double-braces which causes them to be evaluated as a [[JavaScript|http://en.wikipedia.org/wiki/JavaScript]] expression. For example:
|
||
|
|
{{{
|
||
|
|
title:{{window.title}}
|
||
|
|
}}}
|
||
|
|
|
||
|
|
The ParameterParser will cope with either the name or the value being omitted, and will substitute a specified default. This is how the StartupParameters work; the default parameter name is specified as 'open'.
