: include special-character variable

The [[include …]] tag allows to specify include variables — placeholders, together with arbitrary text strings (the include variable's value) that will replace them on the included page.

Although, in general, include variable values may contain any character, some characters may be challenging to enter.

Closing Brackets

If you follow the inc example in the Wikidot syntax documentation

[[include pagename var1=value1 | number_books = 43 | title=Best Wiki Ever
| variable_name = just a variable
| variableName = another variable
]]

and try to add an include variable whose value ends in two (or more) closing brackets (like [[size smaller]]Text to display[[/size]]) with this code

it will fail. Consecutive closing brackets at the very end of an include statement's line will end the include.

Most of the time you can avoid having consecutive closing brackets at the end of a line, by moving the pipe (“|”) symbols (that are separating adjacent include variables) to the end of the line. In the case of the last (or only ) include variable in an include, you can either

• move the two closing brackets (that end the include) to the end of the line, or
• add a pipe (“|”) symbol after the last (or only) include variable (additional pipe symbols do not hurt)

Thus a working code would look like this:

Cannot Move Pipe Symbol to Line End

In case you cannot move a pipe symbol to the end of the line, because the Wikidot syntax requires you to write a tag on its own line ([[include …]] is an example) here's a workaround.

Let's assume you want the value of an include variable to be the following (the value itself should contain another [[include …]]):

Coding

would fail (as the [[include boilerplate]]'s closing brackets end the outer include). Instead you might use:

Pipe Symbol

An even bigger challenge poses the pipe symbol (“|”).

If you try to add an include variable whose value contains an internal link (like [[[page|link text to show]]]) with the code

There is no general solution how to include a pipe symbol in an include variable value, but for special cases there are workarounds.

Rewrite Internal Link

To avoid having to use a pipe symbol in an internal link, rewrite the link in the alternate format.

[/page link text to show]

Include a Page with Pipe Symbol

Here's another idea:

[[include pagename
link=[[[page
[[include :csi:pipe]{$br} |
link text to show]]] |
br=]
]]

 I want this link to change upon my whim: [[[{$page}|{$linktext}]]]

[[include pagename
|var1=[[span]]value1[[/span]]_
|var2=[[[category:page]]]_
]]
