Thank you.

You add both emacs-nim-mode and emacs-commenter. Could you split the
patch into two parts?
> +       (uri (string-append "https://github.com/yuutayamada/commenter/archive/refs/tags/v" version ".tar.gz"))

These URI are not stable. You should use git-fetch with commit
(string-append "v" version) instead.

The synopsis is too long:

  "Set both single- and multi-line comment variables in Emacs"

> +    (description "This package allows you to set both single and multi line comment variables like @code{comment-start} or @code{comment-end} etc.")

I suggest to drop the "etc." since there is "like" before.

  "This Emacs package sets both single- and multi-line comment variables like @code{comment-start} or @code{comment-end}."

Since you're not using a tagged commit, could you put a comment above
the let binding explaining why?

I would add "Emacs": "Emacs major mode for editing Nim source code"

I suggest:

  This package includes major modes for Nim. In particular, it provides
  syntax highlighting for Nim code, Nimble configuration files, and
  @file{nim.cfg}, outlining features, a dedicated compilation command,
  indentation and line breaking.

  It also implements integration with @code{nimsuggest}, the Nim linting
  and completion server, although this is currently unstable.

Could you send an updated patch?
