Can't require evil-magit since Magit switched from magit-popup to Transient

[bmag]

Magit has moved from magit-popup to Transient in magit/magit#3728. As part of it the popup commands were renamed to remove the -popup suffix, resulting in the following error when trying to (require 'evil-magit):

Debugger entered--Lisp error: (void-variable magit-dispatch-popup)
  (copy-sequence magit-dispatch-popup)
  (defvar evil-magit-dispatch-popup-backup (copy-sequence magit-dispatch-popup))
  #<subr require>(evil-magit)
  apply(#<subr require> evil-magit)
  require(evil-magit)
  eval((require 'evil-magit) nil)
  eval-expression((require 'evil-magit) nil nil 127)
  funcall-interactively(eval-expression (require 'evil-magit) nil nil 127)
  call-interactively(eval-expression nil nil)
  command-execute(eval-expression)

I assume there's more to fix than just renaming functions, though :(

@tarsius: maybe you could give hints about what needs to be done.

So far I see obvious things like removing -popup everywhere relevant (e.g https://github.com/emacs-evil/evil-magit/blob/master/evil-magit.el#L532-L549).

Found modifying-existing-transients in Transient's manual (also available via info after installing Transient).

[Jonas Bernoulli]

A quick draft is in #62.

[Justin Burkett]

I'll have to fix the popups later, but at least the current version of evil-magit will work now.

[bmag]

#63 should fix most of the remapping, but not anything forge-related (i.e. "push" and "pull" remapping). Mostly untested, but seems to work for me.

[bmag]

Most of the changes are of the sort:

;; old
(magit-change-popup-key 'magit-tag-popup :actions (string-to-char "k") (string-to-char "x"))
;; new
(transient-suffix-put 'magit-tag "k" :key "x")

But I'm not sure about the "revert" remapping. It contains "V" twice, and it isn't clear how to distinguish them anymore, so I just call transient-suffix-put twice (1st time catches the 1st "V", 2nd time catches the 2nd "V" because 1st isn't "V" anymore at this point):

;; old
(magit-change-popup-key 'magit-revert-popup :actions (string-to-char "V") (string-to-char "O"))
(magit-change-popup-key 'magit-revert-popup :sequence-actions (string-to-char "V") (string-to-char "O"))
;; new
(transient-suffix-put 'magit-revert "V" :key "O")
(transient-suffix-put 'magit-revert "V" :key "O")

@tarsius is there a better way?

For reference, magit-revert definition:

;;;###autoload (autoload 'magit-revert "magit-sequence" nil t)

  "Revert existing commits, with or without creating new commits."
  :man-page "git-revert"

[Jonas Bernoulli]

is there a better way?

Not yet. The plan is to support "paths" (a list of integers, i.e. a position in the tree) as LOC (which is why that argument isn't called just KEY).

[Jonas Bernoulli]

Oh, actually there is. LOC can also be a command.
