how to execute linting?

[DrStrangepork]

I've installed the latest version of this plugin, and I see nothing at all different about VSCode using CFN templates. I see the cfnLint.* options in my Settings but that's it. I see no new buttons, menus, menu options, linting, formatting, etc. When does linting happen? On save?

I can run a locally-installed version of cfn-lint (brew install cfn-lint), and if I run that manually, it shows me warnings and errors, but whether I configure the cfnLint.path in my settings to the local version or the pip installed version, VSCode shows nothing. I assume I am supposed to see something under Problems?

On save? supposed to see something under Problems?

Should be. Something to keep in mind is that it's trying to determine if each file is a CloudFormation template. Should see one of these messages in the Output tab for .json/.yml/.yaml files at least:

In the Output tab, after selecting "CloudFormation linter Language Server", I see this:

Settings have been updated...

It appears that this is what I needed. Perhaps I was just never saving a version of my CFN that had issues, so I didn't see anything under Problems.
