Space After Dot

[Jamesernator]

CoffeeScript allows this:

a.    x
#or 
a. 


x

but it's almost certainly bad style when you can do things like this:

[1,2,3].
    filter((x) -> x % 2 is 0).
    map((x) -> x**2)

# or even worse
[1,2,3].

forEach (x) -> # Not obviously a method call of the previous list just from seeing the function
    console.log(x)

over this:

[1,2,3]
    .filter((x) -> x % 2 is 0)
    .map((x) -> x**2)

[1,2,3]

.forEach (x) -> # Easy to tell it belongs to something previous because of the dot
    console.log(x)

My proposed addition to add a rule to prevent spaces after a property access (spaces before the property access are unchanged)

You're welcome to build and publish a 3rd party rule for this. I don't use CoffeeScript any more, so this is unlikely to get implemented here. If you do implement it make sure to leave a comment here and take a look at https://github.com/clutchski/coffeelint/blob/master/3rd_party_rules.md

I highly recommend replacing CoffeeScript with Babel and CoffeeLint with ESLint. They are better tools that are better supported, and CoffeeScript doesn't appear to have a future as far as I can tell.

this is probably not implementable without hacking it like the indent rule. coffeescript just slurps up the first method in a chained call to the same line as the object callee(?)
