BibTeX, biblatex and biber ⇒ [natbib] Spaces in numerical citation

[khatchad]

Hello. I am using natbib numerical citations, and currently my in-text citations look as follows:

[1, 5, 7–9]

Instead, I would like to condense this if at all possible, and remove the spaces to they would look like this:

[1,5,7–9]

I know it's not a big difference, but I am thinking that it could save some space in the long run. How do I go about doing that? Thanks!

You could try and and

Code: Select all

\makeatletter
\def\NAT@spacechar{}
\makeatother

to your preamble. It will not look very good if you use any of the citation commands that add author names, though, since they all use the same space. You could also use something like

Code: Select all

\makeatletter
\def\NAT@spacechar{\hspace{.5ex}}
\makeatother

to add a smaller space
