Description

« Hide

Add an optional {else} tag in any of the four macros.

This is most intuitive for the show-if, but could easily apply to all four. All the text before the {else} tag will be displayed, or hidden, if ALL or ANY (depending on the matches parameter) of the criteria are matched. The text after the {else} tag will be displayed, or hidden, otherwise.

For example:

{show-if:label=application|scope=HELP:|match=all}
You are on an application page in the help space
{else}
You are not on an application page in the help space
{show-if}

{hide-if:label=application}
You are not on an application page
{else}
You are on an application page
{hide-if}

essentially, once this tag is edited, one would only need to use the show-if, and never the hide-if. for example, the following are equivalent:

{show-if:label=application}{else}
You are not on an application page
{show-if}

{hide-if:label=application}
You are not on an application page
{hide-if}

this also simplifies blocks of code that used to look like this:

{hide-if:label=application|space=apps|scope=catalog > descendents|matches=all}
You are not on an application page
{hide-if}
{show-if:label=application|space=apps|scope=catalog > descendents|matches=all}
You are on an application page
{show-if}

can you please edit the above 'noformat' tags to fix the formatting? I can't edit the issue.

Fixed. Are you suggesting a 'real' macro called {else}, or just a special marker? I'm not sure that the former would really work with the current macro parsing system. Plus, you would have to execute the body markup to determine where the {else} was. Using it as a unique marker would be the only way I think...

my 'hack' user macro, 'if', designed to fill in for when show-if doesn't work or we don't have the right version yet, uses it as a simple text delimiter to split the content. Works well so far.

...
#foreach ($clause in $body.split('\{else\}'))
#if($velocityCount==1)#set($clausetrue=$clause)
#end
#if($velocityCount==2)#set($clausefalse=$clause)#end
#end
...
