<<.from-version "5.1.20">> The primary purpose of the `variables` operator is to implement the <<.mlink dumpvariables>> or the <<.mlink serach-variables>> macros.
|
|
|
|
`[variables:<sort>[<parameters>]]`
|
|
|
|
''Possible Suffixes: <<.place S>>:'' <<.from-version "5.3.4">>
|
|
|
|
* ''alphabetical'' (default): By default the returned list is alphabetically sorted
|
|
* ''raw'': The variable list will be returned as created. The variables "near" the filter run will show up first. So if variables are defined in the tiddler, where the <<.mlink dumpvariables>> or <<.mlink search-variables>> macros are executed, they will be listed first.
|
|
|
|
''Parameters <<.place T>>:'' <<.from-version "5.3.4">>
|
|
|
|
The parameters <<.place T>> allow a ''whitespace separated list'' of variable codes that should be listed
|
|
|
|
* Default is `all` or `fn, var, proc, macro, widget`
|
|
|
|
* ''all'' ... If set it takes precedence and will show all variables
|
|
* ''fn'' ... Will only show variables defined as functions eg: `\function test-01()`
|
|
* ''var'' ... Will only show standard variables defined with eg: `<$let test="test">...</$let>`
|
|
* ''proc'' ... Will only show variables defined as procedures eg: `\procedure test-02()`
|
|
* ''macro'' ... Will only show variables defined as macros eg: `\define test-macro()`
|
|
* ''widgets'' ... Will only show variables defined as widgets eg: `\widget my-widget()`
