indent - option to ignore ternary expressions

[mjomble]

The indent rule supports ignoring many expression types using an off option, such as MemberExpression, FunctionDeclaration, CallExpression, etc.

It would be helpful if it could be similarly configured to ignore ternary expressions.
For example, I prefer a style for multi-line ternaries that is currently considered invalid by the indent rule:

const value = (
  condition ?
  valueIfTrue :
  valueIfFalse
)

I tried the flatTernaryExpressions setting, but the indentation was still reported as incorrect.

Speaking of which, the flatTernaryExpressions setting seems quite out of place compared to the format of the other settings. Perhaps it could be replaced with one named ConditionalExpression (to match the name of the AST node) with options off, flat, etc?

Info on my environment:

• ESLint Version: 4.0.0
• Node Version: 6.9.1
• npm Version: yarn 0.24.6
• Parser: babel-eslint

Is this a dupe of #8712 ?

Is this a dupe of #8712 ?

Not quite. However, I think it will be redundant after #8594 is implemented.

It does look like #8594 would take care of it. Shall I close this issue?

[not-an-aardvark]

Yes, I think I'll close it, since it would be better if we didn't add redundant options.
