I don't know anything about lemonbar, but this sounds OK in principle.


gnu/packages/wm.scm(lemonbar-xft): New variable.

So, it would be nice to change the description (and maybe synopsis) to
set out how this package is different from lemonbar.

Also, regarding the arguments above, I think you can reduce the
duplication with the lemonbar package by doing something like:

  (arguments
   (substitute-keyword-arguments (package-arguments lemonbar)
     ((#:make-flags make-flags)
      (append make-flags
              (string-append
               "CFLAGS="
               (string-join
                (list (string-append "-I" (assoc-ref %build-inputs "freetype")
                                     "/include/freetype2")
                      (string-append "-D" "VERSION="
                                     (format #f "'~s'" ,version)))))))))

I've only just written this in this email, so I'm not sure if it works,
but I think it's close.

Would you be able to send an updated patch?

Thanks,

Chris
