From: "Timothy J. Miller" <tmiller <at> mitre.org> To: bug-gnu-emacs <at> gnu.org Subject: 30.1; file-directory-p in read-file-name prevents TRAMP protocol, user, and host completions Date: Thu, 14 Aug 2025 08:34:43 -0500
From `emacs -Q`:
(require 'tramp)
(read-file-name "With file-directory-p: " default-directory nil t
nil 'file-directory-p)
- Type "/<TAB>" at the prompt. TRAMP protocols are missing from
the completions list.
- Type "/ssh:<TAB>" at the prompt. TRAMP username & hostname are
missing from the completion list.
By way of contrast:
(read-file-name "Without file-directory-p: " default-directory nil
t nil nil)
Repeating the two test cases above, TRAMP suggestions are present.
read-directory-name calls read-file-name with file-directory-p as
the match predicate, and project.el project-prompt-project-dir
loads new projects with read-directory-name. This bug prevents
easy selection of projects on remote servers. Because find-file
works correctly with the same emacs configuration, this breaks
user expectations.
