Emacs C-c C-c用于python码 [英] Emacs C-c C-c for python code

问题描述

我刚刚使用emacs作为一个IDE来蟒蛇。我有pymode和Ropemacs活跃。我的理解是，我应该能够突出一个区域，然后使用C-c C-c将其发送到交互式终端。有没有额外的包，我需要完成这个？

我得到的Cc Cc的错误是：

 错误的类型参数：integer-or-marker-p，nil 
  

我也看到这个链接有一个声明，但这看起来不像我的错误。

更新回答Zack

要设置该变量，进入emacs，并做到这一点：

 （setq debug-on-error t）
  

然后 Mx eval-region

（这是正确的方式设置为true吗？）

然后这是我调试器中出现的：

解决方案

显示的错误来自python-mode.el中的一个错误，它在trunk中已修复。 AFAIK仅在执行非保存缓冲区时发生错误，因此先保存缓冲区使 Cc Cc 工作。

BTW py-execute-区域RET是 Cc | ，而 Cc Cc 将始终发送整个缓冲区，而不管现有区域。如果 C-c C-c 应该尊重一个区域，这可能值得一个功能请求。如有兴趣，请在这里提交：

https： //bugs.launchpad.net/python-mode

仍然是一个个人视图：标记一个区域是昂贵的 - 例如这是一件艰巨的事情，因为它需要一些注意力来界定边界权利，这在边缘问题上更好地利用。 Python模式将通过提供几个命令执行任务来从您处理这些工作。也许看看菜单Python，请参阅执行...部分和按钮更多...。以类似的方式，几个其他的编辑应该更容易。

I'm new to using emacs as an IDE to python. I have pymode and Ropemacs active. My understanding is that I should be able to highlight a region then use C-c C-c to send it to an interactive terminal. Are there additional packages that I need to accomplish this?

The error I'm getting for C-c C-c is:

Wrong type argument: integer-or-marker-p, nil

I saw also this link had a statement on that, but that didn't look like my error.

Update answering Zack

To set that variable, I went into emacs scratch and did this:

(setq debug-on-error t)

Then M-x eval-region

(Is that the right way to set that to true?)

Then this is what appeared in my debugger:

解决方案

The error shown results from a bug in python-mode.el, which is fixed in trunk. AFAIK the bug only occurs when executing a non-saved buffer, so saving the buffer first makes C-c C-c work.

BTW py-execute-region RET is C-c |, while C-c C-c will always send the whole buffer, regardless of an existing region. If C-c C-c should honor a region, that might be worth a feature request. If interested, please file it here:

https://bugs.launchpad.net/python-mode

Still a personal view: marking a region as such is a costly--e.g. a laborious thing, as it requires some attention defining the borders right, which is spent better at the issue at stake itself. Python-mode will take a lot of this work from you by offering a couple of commands what-to-execute. Maybe have a look into the menu "Python", see section "Execute..." and button "More...". In a similar way a couple of other edits should be made easier.
