dmypy-ls 1.13

super fast mypy language server

It leverages mypy.dmypy_server instead of the slow cli interface.

First run takes same time as mypy cli, but next are super fast as mypy.dmypy_server only reload the changed file.

It supports diagnostics only.

Status

On works on Open and Save for now

The on Change could be implemented if the mypy FineGrainedBuildManager uses BuildSource of the dmypy_server instead of always reread file from disk…
