将IPython Shell的工作目录设置为Canopy中正在执行的python文件的工作目录 [英] Setting the working directory of IPython Shell to that of the python file being executed in Canopy

问题描述

我是IPython的新手，我正在使用Canopy发行版。 shell的工作目录的默认值是/ home / username。当我处理需要在我工作的相应文件夹中存在其他文件的文件时，这有点痛苦。

I am new to IPython and I am using the Canopy distribution. The default value of the shell's working directory is /home/username. This is a bit painful, when I work on files which need other files present in the corresponding folder that I am working in.

因此，我总是手动将其更改为文件夹其中存在文件（我正在尝试执行）。

So, I always manually change it to folder in which the file (which I am trying to execute) is present.

我发现这个相关问题，但我的问题略有不同。另外，我无法理解那里提供的答案非常好。

I found this relevant question, but my question is slightly different. Also, I couldn't understand the answer provided there really well.

是否有更短的方法将IPython shell的工作目录设置为文件的工作目录我在干什么？喜欢命令？

Is there a shorter way of setting up the working directory of the IPython shell to that of the file on which I am working? Like a command?

感谢您的帮助

推荐答案

这是我们的功能列表中的功能，但优先级很低。 Canopy提供右键单击上下文菜单选项以切换到当前活动编辑器的目录（请参阅此）。

This is a feature that is on our list of features, but quite low on priority. Canopy provides a right click context menu option to switch to the currently active editor's directory (see this).

此外，作为临时解决方案，您可以使用以下宏来完成工作。

Also, as a temporary work-around, you could use the following macro to get your job done.

# -*- coding: utf-8 -*-

def run():
    code_task = get_active_task()

    from os.path import dirname

    def change_directory():
        code_editor = code_task.active_editor
        if not code_editor:
            return
        python_pane = code_task.python_pane
        active_dir = dirname(code_editor.obj.path)
        python_pane.execute_command(u'cd %s\n' % active_dir)

    code_task.on_trait_change(change_directory, 'active_editor') 

注意：你必须运行这个宏，每次关闭并重新打开编辑器窗口。

Note: You'll have to run this macro, each time you have closed and reopened the editor window.

请参阅 1 和 2 有关如何创建宏以及有关Canopy中宏的更多信息的说明。

See 1 and 2 for instructions on how to create a macro and for more information about macros in Canopy.
