type: text/vnd.tiddlywiki

The <<.def dumpvariables>> [[macro|Macros]] returns a table showing the values of all [[variables|Variables]] and [[macros|Macros]] that exist at that position in the [[widget tree|Widgets]].

It is useful for debugging and exploring ~TiddlyWiki's internals.

Placeholders are replaced with values in the normal way, but using the default values for all macro parameters.

!! Parameters

; type
: If type is empty all variable types are shown: `fn, var, proc, macro, widget`. Using the type parameter will reduce the list.

; raw
: Is used to allow the <<.olink variables>> to return a raw list. By default the list is alphabetically sorted.

; subfilter
: This parameter limits the number of variables that are listed eg:  `subfilter:"[search::some[sort .attr]]" `

; format
: Format the output string using the VariableFormat. Defaults to `$type$ $name$($params$) $firstLine$`.
