Detail

I have the following code in my TWiki/WebTopBar
   * %IF{ "$action~'*Hide*'" then="$percentINCLUDE{\"Help/HideWebLeftBar\"}$percent" }%
<form name="hideshow" action="%SCRIPTURLPATH{"view"}%/%INCLUDINGWEB%/%INCLUDINGTOPIC%" method="get">
<input type="hidden" name="hideleftbar" value="1" />
<input type="image" src="%PUBURL%/%USERSWEB%/DocumentGraphics/%IF{ "$action~'*Hide*'" then="showleftbar.png" else="hideleftbar.png" }%" title="%IF{ "$action~'*Hide*'" then="Show Left Bar" else="Hide Left Bar" }%" name="action" value="%IF{ "$action~'*Hide*'" then="Show Left Bar" else="Hide Left Bar" }%" />
</form>

The code runs when I click on the image. However, the conditional INCLUDE does not work as expected/documented.

ref: IfStatements, Examples,

11. Conditional include
%IF{"'%USERNAME%' ingroup 'ExecutiveGroup'" then="$percntINCLUDE{ExecutiveReport}$percnt"}% 

When the first IF fires (i.e. when $action~'*Hide*') instead of including Help/HideWebLeftBar, it prints the string

$percentINCLUDE{\"Help/HideWebLeftBar\"}$percent

see: http://www.cfcl.com/twiki6/bin/view/System/WebTopBar for this code i_in situ_

-- TWiki:Main/VickiBrown - 2014-03-18

It prints $percentINCLUDE because the syntax is $percnt, not $percent.

I'm so embarrassed!

(Ken Thompson was once asked what he would do differently if he were redesigning the UNIX system. His reply: "I'd spell creat with an e.")
