CoffeeScript expressions in Webstorm debugger evaluate expression window
Hi,
It seems that CoffeeScript syntax is not supported in Webstorm 2016.2.3 for debugging expressions as shown in the print screens below:
- @ as a abbreviation for 'this' returns a syntax error;
- so does array[1..] as an abbreviation for array.slice(1).
Is that correct?
I did not install a CoffeeScript file watcher as I read in this other thread
that it should not be done for Meteor apps adding the Atmosphere CoffeeScript package
Thanks.

OK so not accepting the CoffeeScript array slicing syntax is a registered bug.
But what about not accepting the @ abbreviation for 'this'? Is it also a registered bug?
This is way more serious since, as I understand it, this and @ refer to a different object when @ is used inside the context of methods and functions defined with the fat arrow =>. So is it the case that for those, Webstorm's debugger does not in fact provide any support and hence forces us to fall back to console.log messages to debug code with fat arrows?
https://youtrack.jetbrains.com/issue/WEB-23608 is not about array slicing syntax, it's about ANY coffeescript syntax in watches/evaluate expressions/etc. In order to get the correct result, use the javascript expressions there. It's actually not a bug, it's a missing (complex) feature, because existing sourcemaps can hardly be used here; as far as I can see, Chrome DevTools debugger doesn't work here as well - it behaves in the same way as WebStorm
Thanks for the clarification.
Does the WebStorm debugger supports the EmacScript 6 syntax in watches/evaluate expressions? Or only the EmacScript 5 syntax?
I meant EcmaScript of course ...
EcmaScript5 only...
