How to select the source of displa

[sprig]

Hi!

I have the following expanded helm-mini (I know that I can also rearrange sources for the standard helm-mini, but this is not what I need):

(defun kk/helm-mini ()
  "Preconfigured `helm' lightweight version (buffer -> recentf -> bookmarks)."
  (interactive)
  (unless helm-source-buffers-list
    (setq helm-source-buffers-list
          (helm-make-source "Buffers" 'helm-source-buffers)))
  (let ((helm-ff-transformer-show-only-basename nil))
    (helm-other-buffer '(helm-source-buffers-list
                         helm-source-buffer-not-found
                         helm-source-recentf
                         helm-source-git
                         helm-source-files-in-current-dir
                         helm-source-bookmarks
                         helm-source-f-here
                         helm-source-f-home)
                       "*helm mini*")))

Pretty simple stuff. helm-source-f-* is basically like find <DIR>|grep helm-pattern for the appropriate dir.
helm-source-git is similar, except it works for git-committed files. Definition of helm-source-git:

(setq helm-source-git
  (helm-build-async-source "Files in git"
    :candidates-process
    (lambda nil (if (and (executable-find "git") (eq (call-process "git" nil nil "*kk/git-root*" "rev-parse" "--show-toplevel") 0))
                    (start-process "git ls-files" nil "bash" "-c" (string-join `("git ls-files --full-name|grep '" ,helm-pattern "'")))
                  (start-process "test" nil "test")))
    :action '(lambda (candidate) (find-file (string-join `(,(shell-command-to-string "echo -n $(git rev-parse --show-toplevel)") "/" ,candidate))))))

I'm happy with how each source works separately from the others. My problem is that helm reorders the sources such that candidates from helm-source-files-in-current-dir show above helm-source-git, and I do not understand why.

What am I missing?

Setting up

(setq helm-mini-default-sources '(helm-source-buffers-list
                                  helm-source-buffer-not-found
                                  helm-source-recentf
                                  helm-source-git
                                  helm-source-files-in-current-dir
                                  helm-source-recent-dir-files
                                  helm-source-bookmarks
                                  helm-source-f-here
                                  helm-source-f-home))

and running helm-mini just in case there's something funky with my definition, drops the git source all the way to the bottom.

Async sources when called go in background (just like any async process started with start-process) and the next source is called, if this source is synchronous, Emacs is waiting it to finish and display it, when all sync sources are done the async one popup, if there is more than 1 async source, the faster one wins. PS: Have a look at helm-ls-git package.

Not sure that explanation makes total sense to me, considering that some of the sources that I have usually never exit while producing candidates (e.g. helm-source-f-home, is essentially running find in my homedir). However, it is plausible enough for me to stop spending more time on this, for now. I've settled on making a sync source for now - most of my repos aren't terribly huge.
Fairly ugly but it works:

  (setq helm-source-git
    (helm-build-sync-source "Files in git"
      :candidates
      '(lambda nil (if (and (executable-find "git") (eq (call-process "git" nil nil "*kk/git-root*" "rev-parse" "--show-toplevel") 0))
                      (split-string-shell-command (shell-command-to-string (string-join `("git ls-files --full-name|grep '" ,helm-pattern "'"))))
                     nil))

      :action '(lambda (candidate) (find-file (string-join `(,(shell-command-to-string "echo -n $(git rev-parse --show-toplevel)") "/" ,candidate))))))

I'll check out your package, thanks!
