gvim font style and size

Put this in your .gvimrc file:

if has("gui_running")

  if has("gui_gtk2")

    set guifont=Inconsolata\ 16

  elseif has("gui_macvim")

    set guifont=Menlo\ Regular:h18

  elseif has("gui_win32")

    set guifont=Consolas:h11:cANSI

  endif

endif

This sets the font style and size depending on which environment you are running.  For example, I am running Mac OSX so my font is set to "Menlo Regular:h18".

Select your preferred font by looking at Edit | Font | Show Fonts

To reveal what that means to gvim, run this within gvim:

:set gfn?

For example, if I use the graphical menu to select "English Andale Mono | Regular | 24", the command "set gfn?" would reveal "guifont=Andale Mono:h24"

With that knowledge, we can craft what font we need to provide in the .gvimrc file from above.  Escape spaces with a backslash, so we get:

Andale\ Mono:h24

So my .gvimrc script line would read:

set guifont=Andale\ Mono:h24
