How to reduce Program-Listing line spacing in LyX

Question

Using LyX 2.06.

I have a standard document with 1.5 line spacing, but I want my program listings to use 1.0 line spacing. Is there a simple way to do this?

Answer 1

just add to the \lstset{...}-section

lineskip={-1.5pt}

and: voilá!

Answer 2

You can add the \singlespacing command from setspace (which LyX uses when you set the linespacing to OneHalf or Double) to the \basicstyle of the listings. This will basically add \singlespacing (and any other commands added there) at the start of every code listing. A side effect of this seems to be that some additional whitespace is added before every listing, this can be fixed by setting aboveskip, which is another parameter for Listings, to a negative length.

Hence, go to Document --> Settings --> Listings, and add

basicstyle={\singlespacing},aboveskip={-4ex}

You may want to change the length 4ex. If you have changed the \basicstyle already, just add \singlespacing at the end, e.g.

basicstyle={\ttfamily\singlespacing},aboveskip={-4ex}
