pymacs:一般问题和安装问题

Question

我正在尝试为python开发设置emacs。

据我所读，建议使用python-mode.el而不是Emacs22.3中的默认python.el。所以我开始了新的冒险。

据我所知，python模式有几个依赖项，所以我需要安装绳索、ropemode和ropemacs。除此之外，我还需要安装pymacs。

问:对吗？

这是我的新.emacs：

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(inhibit-startup-screen t)
 '(tab-width 4))
(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 )

(setq emacs-config-path "~/.emacs.d/")
(setq base-lisp-path "~/.emacs.d/site-lisp/")
(setq site-lisp-path (concat emacs-config-path "/site-lisp"))
(defun add-path (p)
  (add-to-list 'load-path (concat base-lisp-path p)))

(add-path "") 
(add-to-list 'load-path "~/.emacs.d")

(require 'psvn)

;; python-mode
;;
(setq auto-mode-alist (cons '("\\.py$" . python-mode) auto-mode-alist))
(setq interpreter-mode-alist (cons '("python" . python-mode) interpreter-mode-alist))
(autoload 'python-mode "python-mode" "Python editing mode." t)


(setq pymacs-load-path '(   "~/.emacs.d/site-lisp/rope"
                            "~/.emacs.d/site-lisp/ropemode"
                            "~/.emacs.d/site-lisp/ropemacs"))


(setq interpreter-mode-alist
      (cons '("python" . python-mode)
        interpreter-mode-alist)
      python-mode-hook
      '(lambda () (progn
            (set-variable 'py-indent-offset 4)
            (set-variable 'py-smart-indentation nil)
            (set-variable 'indent-tabs-mode nil)
            ;;(highlight-beyond-fill-column)
                    (define-key python-mode-map "\C-m" 'newline-and-indent)
            (pabbrev-mode)
            (abbrev-mode)
     )
      )
)


;; pymacs
(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)

;; Search local path for emacs rope
;;

;; enable pymacs
;; 
(require 'pymacs)
(pymacs-load "ropemacs" "rope-")

现在，当我启动emacs时，我收到了以下错误消息：

("C:\\opt\\emacs-22.3\\bin\\emacs.exe")
Loading encoded-kb...done
Loading regexp-opt...done
Loading easy-mmode...done
Loading wid-edit...done
Loading edmacro...done

An error has occurred while loading `c:/opt/cygwin/home/akong/.emacs':

File error: Cannot open load file, pymacs

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

使它变得更加复杂：

由于工作原因，我不得不使用python2.4，但我的PC上安装了python2.6。但显然绳子不喜欢2.4，所以我没有运行setup.py。我解压缩这些包，并将这些文件放在~/.emacs.d/site-lisp下。默认情况下，如果在命令提示符中调用python，它就是python2.4可执行文件。

问:我如何成功地加载'pymacs'?

Answer 1

原来我错过了这两个：

(add-to-list 'load-path "~/.emacs.d/site-lisp/Pymacs-0.23")

显然，我需要加载pymac脚本。

由于工作原因，我将env PYMACS_PYTHON设置为python2.6，因为我使用python2.4作为默认python解释器。

Answer 2

到目前为止，我从未使用过pymacs，但是当我查看您的.emacs时，吸引我注意的一点是，您显然没有将pymacs目录添加到emacs load-path中，而只添加到pymacs目录中：

(setq pymacs-load-path '( "~/.emacs.d/site-lisp/rope"
                          "~/.emacs.d/site-lisp/ropemode"
                          "~/.emacs.d/site-lisp/ropemacs"))

您可能还需要这样的东西：

(add-to-list 'load-path "~/.emacs.d/site-lisp/rope")
(add-to-list 'load-path "~/.emacs.d/site-lisp/ropemode")
(add-to-list 'load-path "~/.emacs.d/site-lisp/ropemacs")

(或者任何有pymacs.el的地方)这样emacs就可以找到lisp文件。在pymacs文档中也提到过

2.4安装Pymacs本身..。对Emacs来说..。 现在这通常是用手做的。首先，沿着您的Emacs加载路径中的列表选择一些目录，您可以对其进行写访问，并在该目录中复制文件pymacs.el。

Answer 3

如果路径丢失，那么在启动日志中或在emacs启动时获得回溯跟踪就很容易发现这一点。如果有疑问的话，是可行的。

我也得到了公司-ropemacs拒绝加载emacs 23和emacs 24后，最新的Debian测试更新，这意味着你不能保存文件，因为绳子保存挂钩。我很想听听任何人的意见。公司我打算稍后再调试它，然后更新这个线程。
