将 emacs 缓冲区发送到任意 Python 进程
我喜欢 python-send-buffer 命令，但是我经常在应用程序中使用嵌入的 Python，或者通过自定义包管理系统启动 Python（以启动具有某些依赖项的 Python）。换句话说，我不能只运行“python”并获得一个有用的Python实例（python-send-buffer依赖的东西）
我想要实现的是：
- 在任何Python解释器（或允许的应用程序中）来评估 Python 代码），导入
magic_emacs_python_server.py模块（根据需要附加到sys.path） - 在 emacs 中，运行
magic-emacs-python-send -buffer
这将评估远程 Python 实例中的缓冲区。
看起来应该很简单——Python 模块在线程中监听套接字。它在主线程中进行计算，并返回结果的 repr() （或者可能捕获 stdout/stderr，或者可能两者都捕获）。 emacs 模块只会将文本发送到套接字，等待响应字符串，并将其显示在缓冲区中。
听起来很简单，这样的东西肯定已经存在了……IPython 有 ipy_vimserver，但这是错误的方法。还有 swank，虽然它看起来非常特定于 Lisp，但有一个 Javascript 后端 看起来很像我想要的...但是搜索几乎什么也没找到，除了一些模糊的（可能是真的）声称 SLIME 不能很好地与非 Lisp 语言一起工作
简而言之：
- 是否存在一个可以发送的项目代码从 emacs 缓冲区到现有的 Python 进程？
- 如果没有，你会如何建议我写这样的东西（对elisp不太熟悉）-SWANK？ IPython的服务器代码？从头开始简单的 TCP 服务器？
I like the python-send-buffer command, however I very often use Python embedded in applications, or launch Python via a custom package management system (to launch Python with certain dependencies).. In other words, I can't just run "python" and get a useful Python instance (something that python-send-buffer relies on)
What I would like to achieve is:
- in any Python interpreter (or application that allows you to evaluate Python code), import a
magic_emacs_python_server.pymodule (appending tosys.pathas necessary) - In emacs, run
magic-emacs-python-send-buffer
This would evaluate the buffer in the remote Python instance.
Seems like it should be pretty simple - the Python module listens on a socket, in a thread. It evaluates in the main thread, and returns the repr() of the result (or maybe captures the stdout/stderr, or maybe both). The emacs module would just send text to the socket, waits for a string in response, and displays it in a buffer.
Sounds so simple something like this must exist already... IPython has ipy_vimserver, but this is the wrong way around. There is also swank, while it seems very Lisp-specific, there is a Javascript backend which looks very like what I want... but searching finds almost nothing, other than some vague (possibly true) claims that SLIME doesn't work nicely with non-Lisp languages
In short:
- Does a project exist to send code from an emacs buffer to an existing Python process?
- If not, how would you recommend I write such a thing (not being very familiar with elisp) - SWANK? IPython's server code? Simple TCP server from scratch?

shell-command没有给你你想要的东西吗？您可以编写包装器脚本或适当调整#!和sys.path。Doesn't
shell-commandgive you what you are looking for? You could write a wrapper script or adjust the#!andsys.pathappropriately.comint 为此类内容提供了大部分基础设施。有很多很好的例子，比如 this 或 this
它允许您运行命令，提供
comint-send-string轻松实现send-region类型命令。Github 上的 dbr/remoterepl 是我在问题。
它缺乏任何形式的修饰，但它基本上可以工作 - 您在目标解释器中导入
replify.py模块，然后在修复后评估emacs-remote-repl.elclient.py的愚蠢硬编码路径comint provides most of the infrastructure for stuff like this. There's a bunch of good examples, like this or this
It allows you to run a command, provides things
comint-send-stringto easily implementsend-regiontype commands.dbr/remoterepl on Github is a crude proof-of-concept of what I described in the question.
It lacks any kind of polish, but it mostly works - you import the
replify.pymodule in the target interpreter, then evaluate theemacs-remote-repl.elafter fixing the stupid hardcoded path toclient.py
