Conditional Statements in Latex

[stantestco]

Hi, how would I go about including conditional statements in Latex?

if

\ifdef DRAFT \else
%%% do some PSTricks stuff in here
\fi


and then I'm able to set DRAFT=1 in some other file, ie a style file.

Thanks!!!

That's in tex. In latex, you'd use the ifthen package which provides stuff like

Code: Select all  •  Open in writeLaTeX

\ifthenelse{     }
{


}
{


}

(Spacing changed to be suggestive; by default it's just \ifthenelse{}{}{} )

[phi]

The etoolbox package offers a solution that is a bit cleaner (no namespace polluting) and faster to type:

Code: Select all  •  Open in writeLaTeX

\usepackage{etoolbox}
\newtoggle{DRAFT}
...
\iftoggle{DRAFT}{yes}{no}

If you want to check for the draft class option, you should use the ifdraft package instead.
