I have solved it by using my package: RCD Template Interpolation System for Emacs: https://hyperscope.link/3/7/1/3/3/RCD-Template-Interpolation-System-for-Emacs.html Like this: (defun wrs-markup-type-link (id link &optional name description) "Return LINK formatted by markup type ID. Optional NAME and DESCRIPTION." (let ((format (rcd-db-table-markuptypes-link-format id))) (rcd-dlet ((rcd::name name) (rcd::link link) (rcd::description description)) (rcd-template-eval format)))) and by having `format' as template, something like this: ⟦ (cond (rcd::description (format "[%s](%s \"%s\") - %s" rcd::name rcd::link rcd::name rcd::description)) (rcd::name (format "[%s](%s \"%s\")" rcd::name rcd::link rcd::name)) (t (format "<%s>" rcd::link))) ⟧ -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
