Bug: :completion-function no longer takes a lambda [9.3.6 (9.3.6-elpa @ /home/arne/.guix-profile/share/emacs/site-lisp/)]

Hi,

I set up my publishing workflow with org-project using lambdas in the
:completion-function, but I now receive errors when I try to publish.

Example Setup:

(setq org-publish-project-alist
      '(("guile-basics"
         :base-directory "~/eigenes/py2guile"
         :publishing-directory (concat private-publish-ftp-proj "guile-basics/")
         :base-extension "org"
         :publishing-function org-html-publish-to-html
         :completion-function (lambda () (private-publish-rename-to-index 
                                           (concat private-publish-ftp-proj "guile-basics/") 
                                           "guile-basics.html"))
         :section-numbers nil
         :with-toc t
         :html-preamble t
         :exclude ".*"
         :include ["guile-basics.org"])))
        

This used to work, but now it breaks with

    org-publish-projects: Invalid function: lambda

Best wishes,
Arne

An additional pair of parens should help as workaround.  Concretely try

    :completion-function ((lambda () (private-publish-rename-to-index 
                                            (concat private-publish-ftp-proj "guile-basics/") 
                                            "guile-basics.html")))

This works since it's possible to use a list of functions also.

I'll commit a fix against master in a second to be able to use a lambda
instead of a list containing one lambda.


Thanks,

That’s awesome — thank you! ♡

Also thank you for the workaround!
