General ⇒ "If" statements in LaTeX... Possible?

[FrankZA]

I have a tricky question. I am busy working on a document that I would like to compile directly to PS and PDF for various reasons.

Is it possible to include if-statements in my code to do something like the following:

Code: Select all

IF compiling to PDF THEN
    \usepackage{PDFstyle}
    \usepackage{hyperref}
ELSE IF compiling to PS THEN
    \usepackage{PSstyle}
    \usepackage{psfrag}
END IF

IF compiling to PDF THEN
    Go to \url{www.latex-community.org}
ELSE IF compiling to PS THEN
    Go to {\tt www.latex-community.org}
END IF

Take a look at the ifthen, the xifthen or the ifpdf package.


Best regards

Thanks Thorsten

I appreciate the help.

The ifpdf package works very well for this problem and I see Heiko Oberdiek has allowed for integration with the ifthen package.

I currently have the following code working:

Code: Select all

\usepackage{ifpdf}
\ifpdf
	\usepackage{Style-PDF}
	\usepackage{hyperref}
	\usepackage[all]{hypcap}
\else
	\usepackage{Style-PS}
	\usepackage{pstricks}
\fi

then further down...

Code: Select all

\ifpdf
	\DeclareGraphicsExtensions{.pdf}
\else
	\DeclareGraphicsExtensions{.ps}
\fi

It also works nicely in my references when I either use \url (PDF) or \textt (PS) for webpages.
