String operations with Usermacros ?

[Joerg Bencke]

Hi Folks, here is an idea, will it work ?

I always meant to ask, if I can perform string-operations on the page titel in usermacros.

The pagetile says "Introduction (Version 1.0)"

The pagebody says something like

h2. Introduction
This is the introduction to the page .....

Now my question : Could I write a usermacro, that takes "Introduction (Version 1.0)" and does something like

h2. {left($pagetitle,pos($pagetitle,"("))}

So basically to cut off anything from "(" onward ?

Regards, Josch

Yes you can do this .... here is an example usermacro code

## @noparams

#set($charIndexToSlice = $content.title.indexOf("(") )
#set($charIndexToSlice = $charIndexToSlice - 1 )

#if($charIndexToSlice  > -1)
    $content.title.substring(0,$charIndexToSlice )
#end
