No visual indication of mypy linting errors

[nathanshelly]

Environment data

• VS Code version: 1.22.2
• Extension version (available under the Extensions sidebar): 2018.3.1
• OS and version: macOS - High Sierra 10.13.4
• Python version: Python 3.6.5
• Type of virtual environment used: N/A
• Relevant Python package - mypy 0.580

Actual behavior

Linting errors from output not displayed visually (no red, squiggly underlining or recognized issues in Problems tab).

Expected behavior

Expect visual indication (in underlining and Problems tab) of mypy linting errors.

Steps to reproduce:

1. Create a new file, add 'hi' + 1 (or anything that should trigger a linting error)
2. Save then see no visible indication that you've written incorrect code (though the Python output shows errors)

Logs

Seems to maybe be related to these issues (though those issues were marked fixed) - #343 & #245

I get red squiggles, so I can't reproduce:

Make sure that you have the following in your settings.json:

"python.linting.enabled": true,
"python.linting.mypyEnabled": true

@brettcannon Speaking of squiggles, I find them a bit too shy and modest in their attempt to bring my attention to the potential problem (especially red squiggles). They are like: "erm, Sir, sorry to disturb you, but there is something you might want to look at", while I'd like them to be more of a: "ERMAHGERD!! THIS INSTANCE DOES NOT HAVE THIS METHOD!! DO SOMETHING ABOUT IT NOW OTHERWISE WE ALL DIE!!!". I mean, I wish red squiggles were a bit more apparent and hard to miss. Yes, they are also marked in the scrollbar, but there they are also a bit tiny. Can errors paint current line in gutter red as well? Or is there an option to increase the line width of the squiggle?

We could use the gutter, but that would be inconsistent with the rest of vscode. This is something you'll have to raise on the vscode repo.

Hi, I am also facing this issue.

"python.linting.mypyEnabled": true

I see all the output correctly in the Output tab:

##########Linting Output - mypy##########
src/core/src/talker.py:6:1: error: Function is missing a type annotation
src/core/src/talker.py:7:5: error: Call to untyped function "init" in typed context

src/core/src/talker.py:36:5: error: Call to untyped function "shutdown" in typed context

However there are no Problems reported or squiggly lines shown.

@eeyang92 please open a separate issue.
