;;; .dir-locals.el
;;
;; 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
;;
;; In Emacs, some buffer locals are referencing the project environment:
;;
;; - prj-root --> <repo>/
;; - 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/")
;;
;; To setup such an environment build target 'pyenv' or 'pyenvinstall'::
;;
;; $ make pyenvinstall
;;
;; Alternatively create the virtualenv, source it and install jedi + epc
;; (required by `emacs-jedi <https://tkf.github.io/emacs-jedi>`_)::
;;
;; $ virtualenv --python=python3 "--no-site-packages" ./local/py3
;; ...
;; $ source ./local/py3/bin/activate
;; (py3)$ # now install into the activated 'py3' environment ..
;; (py3)$ pip install jedi epc
;; ...
;;

;; (global-set-key [f6] 'flycheck-mode)
;; (add-hook 'python-mode-hook 'my:python-mode-hook)
