Add static links for error codes #7186
Description
It would be great to provide a link with a bit more detailed explanation for every error code. For example:
main.py:10: error [bad_variance]: Invariant type variable 'T' used in protocol where covariant one is expected
main.py:10: note: See https://mypy-lang.org/error/bad_variance for more details
The the link will give some explanation why this is an error and links to relevant documentation section on Read the Docs. (Such notes may be shown only once for every error code.)
Something similar is used by SQLAlchemy (but their errors use numerical codes), see e.g. http://sqlalche.me/e/f405.
Depends on #6472

I want to work on this issue. can you tell me where are these errors messages.
JelleZijlstra commentedon Oct 31, 2020
@Shivansh-khare you can grep for them in source code, most of them (maybe all?) appear in
messages.pyI think.Shivansh-khare commentedon Oct 31, 2020
@JelleZijlstra Can I hard code it with msg variable or add error_note_function for every error msg as done with incompatible_argument function at line:563 .

As a first step we can create consistent links in the docs, see #15435
Add option to show links to error code docs (once per code) (#15449)
