Document Classes ⇒ How to output warnings

[Berticus]

The \ClassWarningNoLines and \ClassWarning commands only work when you use the \ProcessOptions command. How do I issue warnings after that?

Code: Select all

\ProcessOptions\relax

\ifthenelse{\boolean{someboolean}}{dosomething}{\ClassWarningNoLines{myclass}{Cannot use this command at this point}}

I get an undefined control sequence error. I also tried this:

Code: Select all

\ProcessOptions\relax

\ifthenelse{\boolean{someboolean}}{dosomething}{\@warning{Cannot use this command at this point}}

But when I do something that should create that warning, it isn't done.

The command is called \ClassWarningNoLine, without 's' at the end. \ClassWarning and \ClassWarningNoLine should work everywhere, independent of \ProcessOptions.
