the 'disable_error_code' option is useless

[tjcjc]

I run this cmd ~/.mypyls/bin/pip install -U mypy to update the mypy to 0.79.0 but the dmypy can't read the 'disable_error_code=arg-call' option.

Can you attach your mypy.ini file and the contents of the mypy plugin output in VS Code (in the Output panel)?

The mypy output info is upside. I also debuged the mypy_server options in mypyls. The .mypy.ini:

[mypy]
ignore_missing_imports=True
show_column_numbers=True
show_error_codes=True
disable_error_code=call-arg,arg-type

[matangover]

Thanks for the details. After some debugging I realized this is indeed a bug in mypyls. Mypy has code in mypy.main.process_options that mypyls never calls, so the list of disabled error codes is not initialized. I could solve this issue specifically but the root cause is that mypyls is using mypy in an unsupported way. What I really want to do is avoid mypyls completely and use dmypy directly.

@tjcjc hi! You can test the beta version of the mypy-vscode extension which now supports disable_error_code. See here: https://github.com/matangover/mypy-vscode/issues/27
