Tiddler (macro)
TiddlyWiki Community Wiki
The tidder macro will insert the contents of another tiddler into the current tiddler; so typing "<<tiddler TiddlerTitle>>" will insert the contents of TiddlerTitle, into the current Tiddler. This is called transclusion. It is also sometimes called a "template" (not to be confused with TiddlyWiki's HTML Templates for page layout), especially if used with variables.
[edit] Example
You have a tiddler called TiddlerOne, with the contents:
This is Tiddler One!
You create a second tiddler with the contents:
This is Tiddler Two! Here's what it says on Tiddler One: "<<tiddler TiddlerOne>>"
When you're done editing, this new tiddler will read:
This is Tiddler Two! Here's what it says on Tiddler One: "This is Tiddler One!"
[edit] Example with variable
You can also add custom content to a transcluded tiddler with one or more variables (called $1, $2, $3, etc.).
In this example, TiddlerOne has the contents:
Hello! My name is $1.
You create a second tiddler, adding "with:", followed by the value of the variable. (If there's more than one variable, each value is separated by a space; values with spaces should be enclosed in quotes or double square brackets):
<<tiddler TiddlerOne with:"Jeremy Ruston">>
When you're done editing, this new tiddler will read:
Hello! My name is Jeremy Ruston.
Tiddler slices can also be transcluded with the tiddler macro.
