To ensure this method run BEFORE the other same methods that run for
other classes:
--8<---------------cut here---------------start------------->8---
(defclass helm-test-class (helm-source-sync helm-type-file)
((candidates :initform (lambda () ("foo" "bar" "baz")))))
=>helm-test-class
(helm-make-source "test" 'helm-test-class)
1) With helm-type-file `helm--setup-source' method is :before
=>
((name . "test")
(candidates lambda nil ("foo" "bar" "baz"))
(action ("Find file" . helm-find-many-files)
("Find file as root" . helm-find-file-as-root)
("Find file other window" . find-file-other-window)
("Find file other frame" . find-file-other-frame)
[...]
(persistent-help . "Show this file")
[...]
(match helm-mp-exact-match helm-mp-3-match)
(header-line . "C-j: Show this file (keeping session)")
(dont-plug helm-compile-source--match-plugin
helm-compile-source--persistent-help)
(matchplugin))
2) With helm-type-file `helm--setup-source' method is only :primary
=>
((name . "test")
(candidates lambda nil ("foo" "bar" "baz"))
(action . identity)
(match helm-mp-exact-match helm-mp-3-match)
(dont-plug helm-compile-source--match-plugin
helm-compile-source--persistent-help)
(matchplugin))
--8<---------------cut here---------------end--------------->8---
As you can see when the helm--setup-source method of helm-type-file is
not :before, the default slots (common to both class) of helm-source-sync
take precedence.
The helm-test-class have to inherit from two classes, and
the helm-type-file class should overhide the default slot of the
helm-source-sync class.
Maybe there is another way to achieve this ?
