Rule: `then-after-if`

[sjbarag]

Some codebases require the optional then keyword at the end of an if/else if statement's condition; others forbid it! Some even require it only for the single-line or only for the block variants of if. An eslint rule means humans don't need to watch for that sort of thing during code reviews!

Schema

Name: then-after-if
Options:

• String (enum)
  • Values: "always" | "block-only" | "line-only" | "never"

if foo then
    print "bar"
end if

Option	Allowed?
always	✅
block-only	✅

    print "bar"
end if

Option	Allowed?
always	🚫
block-only	🚫
line-only	✅
never	✅

Line if statements

Thanks! I should probably just make this a "new issue" template to make proposing new rules easier 🤷
