Hi, I encountered a strange behavior when using a guix.scm file to build and run test in an emacs project. The project is called issue.el[0].
I have the following guix.scm: ---✀---------------------------------------------------------------------------- (use-modules ((guix licenses) #:prefix license:) (guix packages) (guix gexp) (guix download) (guix git-download) (guix build-system emacs) (guix build emacs-utils) (gnu packages) (gnu packages emacs) (gnu packages emacs-xyz) (ice-9 popen) (ice-9 rdelim) ) (define %git-commit (read-string (open-pipe "git show HEAD | head -1 | cut -d ' ' -f2" OPEN_READ))) (define (skip-git-directory file stat) "Skip the `.git` directory when collecting the sources." (let ((name (basename file))) (not (string=? name ".git")))) (package (name "emacs-issue-el") (version (git-version (emacs-header-parse "version" "issue.el") "HEAD" %git-commit)) (source (local-file (dirname (current-filename)) #:recursive? #t #:select? skip-git-directory)) (build-system emacs-build-system) (arguments (list #:tests? (not (%current-target-system)) #:test-command #~'("ert-runner"))) (native-inputs (list emacs-ert-runner)) (propagated-inputs (list emacs-org-jira)) (home-page "https://sr.ht/~plattfot/issue.el") (synopsis "List issues from various issue trackers in emacs") (description "List issues from various issue trackers in a tabulated buffer in @code{Emacs} and act on them. Current supported issue tracker is @code{jira}.") (license license:gpl3+)) -------------------------------------------------------------------------------- If I name the local clone `issue.el` (name of the directory); `guix build -f guix.scm` will fail. It will just copy the file `issue.el` and then `ert-runner` fails as there is no test directory. But if I name the local clone something else, e.g. `issue-el` then it will copy all the files, `ert-runner` will be happy and `guix build -f guix.scm` will succeed. I'm not sure if this is an issue in `emacs-build-system`, `local-file` or plain old user error. [0] https://git.sr.ht/~plattfot/issue.el -- s/Fred[re]+i[ck]+/Fredrik/g
