Cannot use :head (concat ...) in org-roam-bibtex-template about org-roam-bibtex HOT 6 CLOSED

First of all, thanks for this package. It works wonderfully for me :)

Glad you're liking it!

The correct way to do it is:

  (setq org-roam-bibtex-template
        `(("r" "ref" plain (function org-roam-capture--get-point) ""
           :file-name "${=key=}"
           :head ,(concat "#+TITLE: ${=key=}: ${title}\n"
                         "#+ROAM_KEY: ${ref}\n"
                         "- tags ::\n"
           :unnarrowed t)))

Note the backquote =`= and the =,=.

You don't actually need to do that. Compare:

(setq org-roam-bibtex-template
      '(("r" "ref" plain (function org-roam-capture--get-point) ""
         :file-name "${=key=}"
         :head "#+TITLE: ${=key=}: ${title}\n#+ROAM_KEY: ${ref}\n- tags ::\n"
         :unnarrowed t)))

:head accepts a string argument, not a sexp that returns a string argument. Your original solution works, yes, but here, you can just manually concatenate the string by joining all the parts.

Ok, I could figure it out, so instead of deleting the issue, I post the answer I found here: https://emacs.stackexchange.com/questions/38757/cannot-use-concat-within-org-capture-template

The correct way to do it is:

  (setq org-roam-bibtex-template

           :head ,(concat "#+TITLE: ${=key=}: ${title}\n"
                         "#+ROAM_KEY: ${ref}\n"
                         "- tags ::\n"
           :unnarrowed t)))

Thanks for the tip, but I actually plan to have quite large template like:

  (setq org-roam-bibtex-template
        `(("r" "ref" plain (function org-roam-capture--get-point) ""
           :file-name "${=key=}"
           :head ,(concat "#+TITLE: ${=key=}: ${title}\n"
                          "#+ROAM_KEY: ${ref}\n"
                          "- Tags :: %?\n"
                          "- Author(s) :: ${author}\n"
                          "- Year :: ${year}\n"
                          "\n"
                          "* Notes                                                               :ignore:\n"
                          ":PROPERTIES:\n"
                          ":NOTER_DOCUMENT: ../pdfs/${=key=}.pdf\n"
                          ":END:\n")
           :unnarrowed t)))

Which would be quite unreadable without the concat in my opinion.

I agree that it'd get unwieldy quite quickly. I only mentioned this because it saves a few keystrokes and saves an eval, but since it's only a setq assignment for your config, it's a-OK. 👍

Thanks for the tip, but I actually plan to have quite large template like:

You might be interested in using a file-template as explained in #10.

Thanks! I was not aware of this very nice option :).
