Hello, Giacomo Leidi skribis: > * gnu/packages/emacs-xyz.scm (emacs-zerodark-theme): New variable. Thanks for this patch! Below are a couple of suggestions. > +(define-public emacs-zerodark-theme > + (package > + (name "emacs-zerodark-theme") ^ The indentation is off here (you can do M-q to fix it if you use paredit). > + (version "20190528.923") > + (source > + (origin > + (method url-fetch) > + (uri (string-append > + "https://melpa.org/packages/zerodark-theme-" > + version > + ".el")) This URL is unstable: the file will be modified in place regularly. Consequently, could you instead use the upstream Git repository URL along with the ‘git-fetch’ method? > + (synopsis > + "A dark, medium contrast theme for Emacs") ^ Please remove “A”, as suggested by ‘guix lint’. > + (description > + "A dark theme inspired from One Dark and Niflheim. Please write a full sentence (info "(guix) Synopses and Descriptions"). > +An optional mode-line format can be enabled with 'zerodark-setup-modeline-format'.") ^ Please use @code as suggested by ‘guix lint’. Could you send an updated patch? Thanks! Ludo’.
