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明确说明某些内容,请告诉我。)

我已经能够以这样一种方式设置我的包和我的 init.el 文件,以便我能够获得制表符完成、正确的突出显示和 python 片段。我使用 python-mode.el 作为我的 python 模式。 问题都围绕着这个:我想使用 ipython 作为我的 python shell,以便在调试脚本时使用它的选项卡完成功能。

  • 但是,当我启动 ipython(使用 Mx ipython)时,我没有制表符完成。此外,它不会显示“[1] in:”,但会显示“[1] out:”。
  • 我想让 ipython 成为 Emacs 中的默认 shell。但是,对此的尝试失败了(例如,将 C:\PATH\TO\IPython.exe 设置为 py-python-command)。
  • 当我尝试使用 Cc Cc 运行我的 python 脚本时,它使用普通的 Python 运行,并且确实停在我告诉调试器停止的位置(我使用 ipdb.set_trace)。但是,当我使用应该启动 IPython 的另一种类型的命令(例如将区域设置为我的整个脚本并运行 py-execute-region-ipython)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,但我可以像输入文本编辑器一样输入 shell(仅供参考:在迷你缓冲区中它显示“Comint:run shell-compile”)。

我的问题是:我的 init.el 文件中的包版本和 lisp 代码的哪种组合应该允许我使用带有制表符完成的 ipython 作为 Emacs 中的默认 shell?如有必要,我愿意降级一些软件包。

额外信息

从我在 Python-mode.el 的项目页面上阅读的内容来看,我了解到在这个包的最新版本中仍然存在一些关于 IPython 的错误,因此可能需要使用旧版本。我一直在谷歌搜索以寻找解决方案,但我一直无法找到适合我的解决方案。

在 Emacs24 中,我使用默认的 python.el(不是 python-mode.el),它从github开始。

  1. 当我使用python-shell-switch-to-shellC-c C-p(Python 菜单-> 启动解释器)启动 ipython 时,我得到了 ipython。标签完成工作。

  2. ipython 是默认的 python 解释器(参见我的 init 文件)

  3. 当我启动 ipython shell 时,我可以向它发送一个文件或选定的区域(菜单中提供的命令),它会被正确评估。

作为旁注,您可以jedi:setup在 python shell 中启动绝地自动补全。它提供了带有参数帮助和文档的漂亮弹出窗口,您可以选择在点处触发它(而不是在 3 个字符之后)。请参阅IPython auto-completion emacs24 doesn't work。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"
     )

在 IPython-shell 中,作为 python-mode.el 提供它TAB调用py-indent-line。这样循环可能的缩进就像在脚本缓冲区中一样工作。完成时间为M-TAB。您可以重新定义该键。

我不使用 Emacs(我是 VIM 粉丝),但通常当 ipython 不执行制表符完成时,这意味着您缺少 readline 模块https://pypi.python.org/pypi/readline/6.2.2
