Provide a option to enable CtrlP for file searching

[tuhdo]

I think many Vim users are used to CtrlP plugin. It would be nice if we provide a spacemacs option i.e. spacemacs-enable-ctrl-p to use CtrlP for a combined all in one Spacemacs source for file navigation (Helm Projectile sources can be combined and used outside of any directory fine). Here is an example of such command using helm-multi-files:

(setq helm-for-files-preferred-list '(helm-source-buffers-list
                                      helm-source-buffer-not-found
                                      helm-source-projectile-projects
                                      helm-source-projectile-files-list
                                      helm-source-recentf
                                      helm-source-bookmarks
                                      helm-source-file-cache
                                      ;; helm-source-files-in-current-dir
                                      ))

(define-key evil-normal-state-map (kbd "C-p") 'helm-multi-files)

We can then say to use original CtrlP command in Vim, simply press M-/.

[tuhdo]

Or we could just use helm-projectile-sources-list and add the above sources and simply use helm-projectile command. The difference is that you can invoke helm-locate from helm-multi-files with C-c C-p, but then adding Helm Projectile sources to helm-for-files-preferred-list will cause error because Helm Projectile is not yet loaded.

This is interesting, C-S-p could be used as well, I don't think it is used in spacemacs.

[tuhdo]

I think we should just use Ctrl-p, since C-S-p won't work in terminal (which many Vim users are accustomed to) and let user choose it. Ctrl-p is easer to press as well.

[syl20bnr]

So we have to find another key for hippie-expand. I know thhere is already one on M- but in Vim style we use C- instead, M- is not really necessary as opposed with Emacs which is modifier driven.

[tuhdo]

So how about C-/ (for Vim style only)? C-/ is bond to undo-tree-undo, but it already exists with C-u. And C-/ is symmetric: instead moving your pinky above, you move below the ; key.

+1 for C-p even though syl20bnr makes a strong argument against it. Coming from vim this command is so heavily used, it just needs to be C-p. For me, I gave up evil pop but can still use that with M-y, which i'm more used to using anyways with emacs.

Just my 2 cents from someone coming here having had experience with Ctrl-p under Vim and looking for "open file" functionality. You can open a file using SPC f f. It doesn't search recursively, but then I keep my projects small and don't need it.

[sdwolfz]

Also my 2¢, I am a C-p vim user. When switching to Spacemacs I found out about SPC p f which is helm-projectile-find-file. This is the CtrlP equivalent AFAIC.

[thorvn]

I am a vim user. When I switching to Spacemacs. I config like this(remember to reload your spacemacs):
(define-key evil-normal-state-map (kbd "C-p") 'helm-projectile-find-file)
So now, you can use like CtrlP.

[dkrieger]

Is there a way to make projectile treat the current directory as if it were a project dynamically, i.e. without actually placing an empty .projectile file in the dir? This is how I have fzf configured to work in vim, and it's extremely useful. If i'm in netrw, it uses '%', if I'm in a file, it uses '%:h'
