Support --fix on attribute-indentation

[mehulkar]

The attribute-indentation rule is about style and is very annoying to fix when things go wrong. A --fix option would be very helpful.

ember-template-lint-plugin-prettier which is autofixable might be the future here instead of that rule.

I was trying to figure that out today with a coworker! I wasn't sure if ember-template-lint . --fix was intended to use the prettier plugin under the hood or not. Is the plan to make the prettier plugin part of the ember blueprint or bring it in via this package?

Will defer to @rwjblue and @dcyriller on that.

Last I heard, attribute-indentation had some instabilities too.

And looks like this topic was previously discussed in #1523.

We should update the attribute-indentation rule doc with more context/advice.

@mehulkar sorry for the late reply.

I am a bit biaised on this as I wrote the plugin. I use it in my projects. It allows me to run ember-template-lint . --fix in my editor (through a key binding) to format the hbs files with prettier. This is convenient.

Is the plan to make the prettier plugin part of the ember blueprint or bring it in via this package?

I think the plugin could be added to the ember blueprint. To do so, it would probably have to go through the RFC process.

Could be fixed by: #2271
