The package definitions imported by Guix importers do not respect Guix conventions regarding indentation.
Consider: guix pypi import transaction (package (name "python-transaction") (version "2.4.0") (source (origin (method url-fetch) (uri (pypi-uri "transaction" version)) (sha256 (base32 "17wz1y524ca07vr03yddy8dv0gbscs06dbdywmllxv5rc725jq3j")))) (build-system python-build-system) (propagated-inputs `(("python-zope.interface" ,python-zope.interface))) (native-inputs `(("python-coverage" ,python-coverage) ("python-mock" ,python-mock) ("python-nose" ,python-nose))) (home-page "https://github.com/zopefoundation/transaction") (synopsis "Transaction management for Python") (description "Transaction management for Python") (license #f)) Re-identing this in Emacs with the Guix .dir-local.el indentation customizations yields: (define-public python-transaction (package (name "python-transaction") (version "2.4.0") (source (origin (method url-fetch) (uri (pypi-uri "transaction" version)) (sha256 (base32 "17wz1y524ca07vr03yddy8dv0gbscs06dbdywmllxv5rc725jq3j")))) (build-system python-build-system) (propagated-inputs `(("python-zope.interface" ,python-zope.interface))) (native-inputs `(("python-coverage" ,python-coverage) ("python-mock" ,python-mock) ("python-nose" ,python-nose))) (home-page "https://github.com/zopefoundation/transaction") (synopsis "Transaction management for Python") (description "Transaction management for Python") (license #f))) Multiple record fields indentation offset is set to 1 instead of the regular 2. This is produced by the function pretty-print from ice-9. Maybe there's a way to configure the indentation rules used by pretty-print?
