Minor modes and file names

Minor modes and file names

[steve-humphreys]

I have made a minor made for texinfo and noticed that the minor mode
does not take effect unless tho file name matches the minor mode name.

For instance, changing the name of the file to "crucible-mode-2021-01-28.el"
the minor mode fails to load.

----- crucible-mode.el -----
(define-minor-mode crucible-mode ...)
(provide 'crucible-mode)

----- gtexinfo.el -----
(add-to-list
   'load-path "~/Genadm/build/gungadin-1.0/elisp/crucible")
(require 'crucible-mode)
(add-hook 'texinfo-mode-hook 'crucible-mode)

This is expected and documented:

    (require FEATURE &optional FILENAME NOERROR)

      Probably introduced at or before Emacs version 15.

    If feature FEATURE is not loaded, load it from FILENAME.
    If FEATURE is not a member of the list `features', then the feature is
    not loaded; so load the file FILENAME.

    If FILENAME is omitted, the printname of FEATURE is used as the file
                                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    name, and `load' will try to load this name appended with the suffix
    `.elc', `.el'

Have tried to use it, but have encountered difficulties

(add-to-list
   'load-path "~/Genadm/build/gungadin-1.0/elisp/crucible")
(require 'crucible-mode crucible-mode-prot-2021-01-28-utc0656)
(add-hook 'texinfo-mode-hook 'crucible-mode)

The second arg has to be a string, i.e,

  (require 'crucible-mode "crucible-mode-prot-2021-01-28-utc0656")
