Support python lsp in monaco

Monaco Editor LSP

该项目是基于 monaco-editor 以及 python-languageserver 开发的带有 intellisense、auto-complete 等 LSP 能力（language server protocol）的编辑器。

项目分为 client 和 server 两端：

• client：基于 express 运行的 nodejs 服务，提供编辑器页面
• server：基于 tornado 的 python web server，通过 pyls-jsonrpc 提供 LSP 服务

client 和 server 之间的连接方式是 websocket，通过 typefox 的 monaco-languageclient 包向 server 发送补全求情，在收到补全信息后，monaco-languageclient 会在 monaco 内展示补全内容。

本地调试开发教程：

1. 安装 python 依赖(python 3.4+)

pip install tornado python-jsonrpc-server

| 安装依赖的时候使用python-jsonrpc-server，调用的时候用pyls_jsonrpc的包名 （出处）

2. 运行脚本

python python-server/langserver_ext.py

3. 访问http://localhost:3001/python（默认启动端口，可自己修改），若有"Can "Upgrade" only to "WebSocket"."的文字提示，即服务其成功启动

4. 启动 expres

安装依赖

yarn

编译 ts 代码

yarn prepare

启动 express

yarn start:ext

5. 访问http://localhost:3002/（默认启动端口，可自己修改）,能看到带语法高亮、输入 python 代码有自动补全，即运行成功

pyls_jsonrpc 这个包不存在

rt
目前有个需求，用monaco做一个python自动补全的编辑器，目前能找到类似的，貌似只有这个库，但是本地跑不起来，
pip install pyls_jsonrpc 报错，然后我去搜这个包，不存在
所以来问下，这个问题有办法解决么？
万分感谢🙏

How to implement custom completion items through pyi scripts?

非常感觉您的项目, 正是我需要的. 然后我还有另外一项功能, 不知道该怎么实现了. 您有空帮忙看看.

我想实现内置一些class, function, variable到编辑器中, 这些都需要是动态注入的,可能经常变化. 而且没有实现,只有声明.

我能想到的是使用 .pyi 文件来做这件事. 但是不知道该怎么把我自定义的文件注入到pyls/lsp/jedi中

ex: ide.pyi

class Person:
    def study(self) -> None: ...
    def play(self) -> None: ...

当我写如下代码时, 第一行的Person, 第二行的study 都能够自动提示出来

p = Person()
p.study()
