;; Per-Directory Local Variables:
;; https://www.gnu.org/software/emacs/manual/html_node/emacs/Directory-Variables.html
;;
;; .. hint::
;;
;; If you get ``*** EPC Error ***`` (even after a jedi:install-server) in
;; your emacs session, mostly you have jedi-mode enabled but the python
;; enviroment is missed. The python environment has to be next to the
;; ``<repo>/.dir-locals.el`` in::
;;
;; ./local/py3
;;
;; To setup such an environment, build target::
;;
;; $ make pyenv.install
;;
;; Some buffer locals are referencing the project environment:
;;
;; - prj-root --> <repo>/
;; - nvm-dir --> <repo>/.nvm
;; - python-environment-directory --> <repo>/local
;; - python-environment-default-root-name --> py3
;; - python-shell-virtualenv-root --> <repo>/local/py3
;; When this variable is set with the path of the virtualenv to use,
;; `process-environment' and `exec-path' get proper values in order to run
;; shells inside the specified virtualenv, example::
;; (setq python-shell-virtualenv-root "/path/to/env/")
;; - python-shell-interpreter --> <repo>/local/py3/bin/python
;;
;; Jedi, flycheck & other python stuff should use the 'python-shell-interpreter'
;; from the local py3 environment.
;;
;; Other useful jedi stuff you might add to your ~/.emacs::
;;
;; (global-set-key [f6] 'flycheck-mode)
;; (add-hook 'python-mode-hook 'my:python-mode-hook)
;;
;; (defun my:python-mode-hook ()
