View source for $replacex

Replaces any occurrence of substring in string with newstring except for replacements that have already been made.
 $replacex(string,substring,newstring,...)

This is the same as [[$replace]] but it doesn't replace already replaced text (see example below).

[[$replacexcs]] is the case-sensitive version of $replaxce.

== Example ==
 ; set a test text
 [[var]] %mytext = This is moo
 ; actually replace substrings
 var %mynewtext = $replacex(%mytext,is,moo,moo,foo)
 ; echo it to the active window
 [[echo]] -a %mynewtext
This example will echo ''Thmoo moo foo'' as at first ''is'' was replaced by ''moo'' and after that, all ''moo'' that are no replacement, replaced by ''foo''.

To reverse any changes a user makes to the channel, take a look at [[Undo_Modechanges|this script]].
