Remove current buffer from helm-projectile-switch-project

[dsdshcym]

Every time I use helm-projectile-switch-project, I find that the current buffer is in the Project buffers section.

This behavior is really odd most of the time. Cause if I use helm-projectile-switch-project instead of helm-projectile-find-file, the current buffer is clearly not the file of the Project I want.

And I also find that the current buffer's path is changed to the chosen project path.

Like this:

But the original path of ics.org is:

Actually, helm-projectile-switch-project reuses (and thus, display) the same buffer list as projectile-switch-project. So, if you want to exclude it, simply cdr the current list.

@tuhdo I still don't understand.

I looked into projectile's source file. And I didn't find which list I should cdr.

[tuhdo]

@dsdshcym You can replace this line with this line:

(candidates :initform (cdr helm-buffers-list-cache))

[dsdshcym]

@tuhdo Thank you!
I'm wondering why this is not default behavior. Are there some other concerns?

[tuhdo]

Probably no one notices it. You should make a PR.

This fix seemed to break helm-projectile-switch-to-buffer for me for some reason, causing it to yield an empty buffer list without any error.

Curiously, by doing the cdr earlier, on line 500 instead like so:

(setq helm-buffers-list-cache (cdr (projectile-project-buffer-names)))

The problem magically disappears (with the current buffer omitted from the list).

Anyone else getting this?

@hlissner yea I fixed it with this PR: #742

Awesome, thanks!
