Thanks everyone for explaining. The fog is clearing. One case I have where it is immediately useful - when CamelCase is turned on and I don't want CamelCase linking to apply. This can cause mayhem when working with variables that contain text in CamelCase. I only realised this when, for testing, I moved a perfectly working macro (where CamelCase was off) into tiddlywiki.com (where CamelCase is on). I found it extremely difficult to fix!
Abbreviated example: In tiddlywiki.com try the below *with* and *without* the \rules line. \define makeLink(site link) \rules except wikilink <a href="$link$" target="_blank">$site$</a> \end <<makeLink TiddlyWiki https://tiddlywiki.com/>> With *\rules except wikilink* - the link created is correct: TiddlyWiki <https://tiddlywiki.com/#%24%3A%2Fcore%2Fmodules%2Fparsers%2Fwikiparser%2Frules%2Frules.js> : https://tiddlywiki.com/ Without \rules - the link is wrong: TiddlyWiki <https://tiddlywiki.com/#TiddlyWiki> : https://tiddlywiki.com/#TiddlyWiki Cheers On Thursday, January 10, 2019 at 6:01:25 PM UTC+7, @TiddlyTweeter wrote: > > The "pragma" can be switched off or switched on selectively as others have > indicated.
