Not having any practical experience with docbook-xsl, I think this change looks fine, in general. I think the commit message should be like this: * gnu/packages/documentation.scm (asciidoc)[inputs]: Add docbook-xsl. [arguments]: Add 'make-local-docbook-xsl' phase. That is closer to the GNU Changelog format that we prefer to use. > + (add-before > + 'install 'make-local-docbook-xsl I think these two lines can collapsed into a single line. > + (lambda* (#:key inputs #:allow-other-keys) > + (substitute* (find-files "docbook-xsl" ".*\\.xsl$") > + (("xsl:import > href=\"http://docbook.sourceforge.net/release/xsl/current") > + (string-append > + "xsl:import href=\"" > + (string-append (assoc-ref inputs "docbook-xsl") > + "/xml/xsl/docbook-xsl-" > + ,(package-version docbook-xsl)))))))))) My limited sense of Scheme style tells me to shift the previous 4 lines to the right by 1 character. The function should return #t, since (substitute*) has no defined return value.
