Manual	dplvar

Syntax

Sets one symbolic variable name and assign a value:

{{#dplvar:set|varname|valueofvar}}

Sets multiple symbolic variable names and assigns values to them (one after the other):

{{#dplvar:set|name1|value1|name2|value2|..|..}}

Assigns a value only if the variable is empty / has not been used so far:

{{#dplvar:default|name|value}}

Returns the current value of the variable:

{{#dplvar:name}}

The variables can be set and retrieved from an article page or from templates used in that article.

Example

{{#dplvar:set|a|x|b|y|c|<!--empty-->}} {{#dplvar:default|a|aaaa}} {{#dplvar:default|c|cccc}} {{#dplvar:default|d|dddd}}

Result:

a={{#dplvar:a}}
b={{#dplvar:b}}
c={{#dplvar:c}}
d={{#dplvar:d}}

Notes:

Variable "c" was set to "cccc" because it was set but with an empty note (empty value).
Variable "d" was set to "dddd" because it was not already set.
