python模式、ipython、(ipython.el)版本/发行版和init.el/.emacs.d代码的哪个组合可以工作？

Question

我的目标是使用Emacs 24作为我的python编辑器(也有一个Matlab和R编辑器，但这不是我的问题所在)。

(如果我遗漏了任何信息，或者我没有说清楚的话，请告诉我。)

我已经能够设置我的包和我的init.el文件，使我能够获得标签完成，正确的高亮显示和代码片段的python。我使用python-mode.el作为我的python模式。问题都围绕着这一点:我希望使用ipython作为我的python，以便在调试脚本时使用它的选项卡完成函数。

• 但是，当我启动ipython (使用completion )时，没有选项卡完成。此外，它没有显示"1 in:"，但是它显示了"1 out:“。
• 我想在Emacs中将ipython作为我的默认shell。但是，尝试失败了(例如，将C:\PATH\TO\IPython.exe设置为py-python-命令)。
• 当我试图使用C-c C-c运行我的Python脚本时，它使用普通的python运行，并且确实在我告诉调试器停止的位置停止(我使用ipdb.set_trace)。但是，当我使用另一种类型的命令来启动IPython (比如将区域设置为整个脚本并运行py-)时，IPython不起作用。它确实启动了一个IPython shell，或者至少看起来是这样，但是我可以像输入文本编辑器一样输入shell (fyi:在迷你缓冲区中显示"Comint:run编译“)。

，我的问题是：文件中的包版本和lisp代码的组合应该允许我在init.el文件中使用带有选项卡完成的ipython作为我的默认shell？如果有必要的话，我愿意降低一些软件包的等级。

附加信息

根据我在Python-mode.el的项目页面上所读到的内容，我了解到在这个包的最新版本中仍然存在一些关于IPython的bug，所以可能有必要使用旧版本。我一直在谷歌上搜索一个解决方案，但我一直找不到适合我的解决方案。

我在跑

• python-模式6.1.3，
• ipython 1.1.0
• 我尝试了来自https://raw.github.com/ipython/ipython/d2d967af9de6081c8cdbab0eab1115164e5e72bd/docs/emacs/ipython.el的https://raw.github.com/ipython/ipython/d2d967af9de6081c8cdbab0eab1115164e5e72bd/docs/emacs/ipython.el，但是通过与python-mode.el的开发人员联系，这似乎是不可取的，并且没有集成到python-mode.el中。
• GNU Emacs 24.3.1 (i 386-mingw-nt6.1.7601)
• Windows 7 64位

我的init.el看起来像(python在底部)：

对于Emacs24，我使用默认的python.el (不是python-mode.el)，它启动了论github。

1. 当我用python-shell-switch-to-shell或C-c C-p (Python -> start解释器)启动ipython时，我会得到ipython。标签完成工程。
2. ipython是默认的python解释器(请参阅init文件)
3. 启动ipython后，我可以向其发送一个文件或选定的区域(菜单中可用的命令)，并对其进行正确的评估。

顺便提一句，当你身处巨蟒外壳时，你可以用jedi:setup启动绝地自动完成。它提供了很好的弹出框参数帮助和文档，你可以选择在点(而不是在3个字符之后)激发它。见IPython自动完成emacs24不工作。它可以看作是对ipython的补充而不是替代。

按照我的配置：

;; trying ipython tab completion: that works :)
(setq
 python-shell-interpreter "ipython"
 python-shell-interpreter-args ""
 python-shell-prompt-regexp "In \\[[0-9]+\\]: "
 python-shell-prompt-output-regexp "Out\\[[0-9]+\\]: "
 python-shell-completion-setup-code "from IPython.core.completerlib import module_completion"
  python-shell-completion-module-string-code "';'.join(module_completion('''%s'''))\n"
  python-shell-completion-string-code "';'.join(get_ipython().Completer.all_completions('''%s'''))\n"
     )

希望这能有所帮助。

Answer 2

我不使用Emacs (我是一个VIM迷)，但是通常当ipython不执行选项卡完成时，它意味着您缺少了读行模块https://pypi.python.org/pypi/readline/6.2.2
