[英]How can I make emacs-jedi use project-specific virtualenvs
我想emacs-jedi檢測我在不同項目中編輯文件的時間,並使用相應的virtualenv(如果可用)。 按照慣例,我的virtualenvs與我的項目同名。 它們位於$HOME/.virtualenvs/
我找到了kenobi.el,但它假設在項目根目錄的bin目錄中找到了virtualenvs。 它還有一些我根本不需要的其他功能。
在kenobi.el的啟發下,我為jedi編寫了以下初始化。 它工作得很好,但並不完美。
如果我從項目中導入庫A
,則A
導入B
我能夠跳到A
定義的定義,但是一旦出現,我就無法繼續跳到B
定義。
我的初始化:
(defun project-directory (buffer-name)
(let ((git-dir (file-name-directory buffer-name)))
(while (and (not (file-exists-p (concat git-dir ".git")))
git-dir)
(setq git-dir
(if (equal git-dir "/")
nil
(file-name-directory (directory-file-name git-dir)))))
git-dir))
(defun project-name (buffer-name)
(let ((git-dir (project-directory buffer-name)))
(if git-dir
(file-name-nondirectory
(directory-file-name git-dir))
nil)))
(defun virtualenv-directory (buffer-name)
(let ((venv-dir (expand-file-name
(concat "~/.virtualenvs/" (project-name buffer-name)))))
(if (and venv-dir (file-exists-p venv-dir))
venv-dir
nil)))
(defun jedi-setup-args ()
(let ((venv-dir (virtualenv-directory buffer-file-name)))
(when venv-dir
(set (make-local-variable 'jedi:server-args) (list "--virtual-env" venv-dir)))))
(setq jedi:setup-keys t)
(setq jedi:complete-on-dot t)
(add-hook 'python-mode-hook 'jedi-setup-args)
(add-hook 'python-mode-hook 'jedi:setup)
我如何初始化jedi有什么問題?
我現在已經確定了一個使用virtualenvwrapper ELPA包來激活virtualenvs的解決方案,允許emacs-jedi從VIRTUAL_ENV環境變量中獲取virtualenv路徑。
這是一個完整的,有效的emacs-jedi初始化:
(defun project-directory (buffer-name)
"Return the root directory of the project that contain the
given BUFFER-NAME. Any directory with a .git or .jedi file/directory
is considered to be a project root."
(interactive)
(let ((root-dir (file-name-directory buffer-name)))
(while (and root-dir
(not (file-exists-p (concat root-dir ".git")))
(not (file-exists-p (concat root-dir ".jedi"))))
(setq root-dir
(if (equal root-dir "/")
nil
(file-name-directory (directory-file-name root-dir)))))
root-dir))
(defun project-name (buffer-name)
"Return the name of the project that contain the given BUFFER-NAME."
(let ((root-dir (project-directory buffer-name)))
(if root-dir
(file-name-nondirectory
(directory-file-name root-dir))
nil)))
(defun jedi-setup-venv ()
"Activates the virtualenv of the current buffer."
(let ((project-name (project-name buffer-file-name)))
(when project-name (venv-workon project-name))))
(setq jedi:setup-keys t)
(setq jedi:complete-on-dot t)
(add-hook 'python-mode-hook 'jedi-setup-venv)
(add-hook 'python-mode-hook 'jedi:setup)
請記住,您必須先安裝virtualenvwrapper。
閱讀virtualenvwrapper文檔 ,了解自動激活項目虛擬環境的另一種方法。 簡而言之,您可以在項目的根目錄中創建.dir-locals.el
文件,其中包含以下內容:
((python-mode . ((project-venv-name . "myproject-env"))))
將"myproject-env"
更改為virtualenv的名稱,並使用python-mode
鈎子激活virtualenvironment:
(add-hook 'python-mode-hook (lambda ()
(hack-local-variables)
(venv-workon project-venv-name)))
(add-hook 'python-mode-hook 'jedi:setup)
