YueScript compile error with line comments wrong indent

[GokuHiki]

I encounter this error when work with class. Nothing is serious but maybe you could take a look.

class Behavior
  Start: =>
    Debug.Log("START!")  
-- Observable.EveryUpdate()\Subscribe ->Debug.Log("UPDATE!")
    observable = Observable.EveryUpdate()
    -- observer = Observer.CreateSubscribeObserver((->Debug.Log("UPDATE!")), Stubs.Throw, Stubs.Nop)
    -- disposable = observable\Subscribe observer
    -- DisposableExtensions.AddTo disposable, @actor
  Update: =>

It show error:

5: unexpected indent
    observable = Observable.EveryUpdate()
    ^

Thanks and regards!

That’s not a bug, it’s an indent based language and you had a line with 0 indent so you closed the class.

No. In indent based language or whatever programming language, inline comments are ignored. So a full line comment would be treated as a blank line. And the blank line is total ignored. EX: python, moonscript, livescript, coffeescript, etc... are all indent based language. And they all ignore full inline comments.

It's intended behavior in Yuescript. I forced the comment to follow the code indent or an advanced indent. You can find the syntax rules here.

Yuescript/src/yuescript/yue_parser.cpp

Lines 842 to 846 in e66f562

	empty_line_break = (
	check_indent >> (multi_line_comment >> space | comment) |
	advance >> ensure(multi_line_comment >> space | comment, pop_indent) |
	plain_space
	) >> and_(line_break);

The mis-indented comments have inconsistent behaviors in Moonscript, they will either break or not break blocks in different syntax.
