microsoft/vscode-mypy's langauge server extension for coc.nvim.

CocInstall:

:CocInstall @yaegassy/coc-mypy

When using a plugin manager, etc:

e.g. vim-plug

Plug 'yaegassy/coc-mypy', {'do': 'yarn install --frozen-lockfile'}

coc-mypy allows you to create an extension-only "venv" and install microsoft/vscode-mypy's langauge server.

When using coc-mypy for the first time, if microsoft/vscode-mypy's langauge server is not present in the runtime environment, you will be prompted to do a built-in install.

To use the built-in installation feature, execute the following command.

:CocCommand mypy-type-checker.installServer

The microsoft/vscode-mypy language server uses dmypy by default. If you want to use mypy, set mypy-type-checker.useDmypy to false.

coc-settings.json:

{
  "mypy-type-checker.useDmypy": false
}

If you are using dmypy, the process of killing the dmypy process is included when Vim/Neovim exits. This may slow down the Vim/Neovim exit process slightly.

The mypy command takes time to complete execution if the cache file for mypy does not exist. In other words, the first time it is executed, it takes time.

The same is true if you are using a language server, so it will take some time to display the initial diagnostics.

• mypy-type-checker.enable: Enable coc-mypy extension, default: true
• mypy-type-checker.useDmypy: Use dmypy deamon mode as the linting command run by microsoft/vscode-mypy's language server, default: true
• mypy-type-checker.builtin.pythonPath: Python 3.x path (Absolute path) to be used for built-in install, default: ""
• mypy-type-checker.showDocumantaion.enable: Whether to display the code action for open the Mypy rule documentation web page included in the diagnostic information, default: true
• mypy-type-checker.trace.server: Traces the communication between coc.nvim and the language server, default: "off"

Other settings have the same configuration as microsoft/vscode-mypy.

• mypy-type-checker.restart: Restart Server
• mypy-type-checker.installServer: Install Server
• mypy-type-checker.showOutput: Show output channel
• mypy-type-checker.version: Show the version of the server installed by the extension

• microsoft/vscode-mypy
