It also hard-depends on ncurses (for tput), gawk, sed, & grep. You can substitute* these as well, or use wrap-script (which requires adding guile-3.0) since ‘performance’ probably doesn't matter here. But read on. Keeping optional dependencies (like sudo) up to the user is good. > + (arguments > + `(#:modules ((guix build utils)) > + #:builder > + (begin > + (use-modules (guix build utils)) > + (copy-recursively (assoc-ref %build-inputs "source") > ".") > + (substitute* "hosts" > + (("/usr/bin/env bash") > + (string-append (assoc-ref %build-inputs "bash") > + "/bin/bash"))) > + (install-file "hosts" (string-append %output "/bin")) We should copy LICENSE and README to /share/doc/,name-,version too. > + (let ((bash-completion (string-append %output > + > "/etc/bash_completion.d"))) > + (mkdir-p bash-completion) > + (copy-file "etc/hosts-completion.bash" > + (string-append bash-completion > "/hosts"))) > + #t))) > + (home-page "https://github.com/xwmx/hosts/") > + (synopsis "Command line hosts file editor in a single > portable script") I don't think ‘in a single portable script’ (like ‘Free’ or ‘cross-platform’ or ‘now contains Rust!’) adds value here.

Users will have to invoke it as ‘sh ./hosts’ to skip the patched shebang, but it would work. If we patch or wrap it to include store patch for all dependencies it won't be true at all. If this feature matters to you, I think you could do something like (substitute* "hosts" (("#!/usr/bin/env bash") (string-append "#! "(assoc-ref %build-inputs "bash") "/bin/bash\n" ;; Just a rough example. "PATH=\"" (getenv "PATH") ":$PATH\""))) To avoid a separate .hosts-real file and keep the script working both in pure environments and when scp'd to random hosts. But Guix packages in general don't care about being self-contained like this. Maybe it's not worth supporting; one can always curl the unguixed original instead? > + (license license:expat))) I've opened a bug report about the unclear licencing: <https://github.com/xwmx/hosts/issues/10>. Kind regards, T G-R

Hello, Thank you for review! I applied all your suggestions, added ZSH completion and tests. Pushed as ceb233bb7642b2a7efec57073bf205b62ebd8f97. Oleg.
