Math & Science ⇒ using \mathbb{R} in listings code

[mikey]

Hi there,

For some reason when I'm using

Code: Select all

\lstdefinelanguage{mathpseudo}{
	literate={R} {$\mathbb{R}$}{1},
	escapeinside={(*}{*)}
}

And I try a R in my code it just appears as a normal R. If I change \mathbb{R} to say \le then I get a less than or equal sign, and if I put the escape sequence in my code (*$\mathbb{R}$*) I get a properly formatted R...

Does anyone know how to get the function I want?

Try an extra set of braces around $\mathbb{R}$:

Code: Select all

\lstdefinelanguage{mathpseudo}{
   literate={R} {{$\mathbb{R}$}}{1},
   escapeinside={(*}{*)}
}

(See p. 49 of the listings manual.)

Thanks, worked a treat.
