Interpolation with CoffeeScript HAML filter

[jacob-carlborg]

I have a view file written in haml which uses the coffeescript filter and having problem with string interpolation. Since haml uses the #{} syntax for inline ruby and coffeescript uses the same syntax for string interpolation there is a conflict. What happens is that haml will always see the #{} syntax as inline ruby making it basically impossible to use string interpolation in a coffeescript filter. Any idea if this is possible to solve?

Honestly, I'm not sure - It's likely solveable but would require using alternative syntax in coffeescript - I believe (but am not sure) that using \# (e.g. \#{} should fix it.

Ok, I'll give it a try.

i am having this issue as well. no way to differentiate interpolated ruby from interpolated js. i tried escaping the hash, but it just returns a string with an escape in it (e.g. "\#{ruby_variable}"

Same issue here.

To get really hacky, would

"javascript string #{"\#{interpolated javascript string}"} javascript string"

work? Assuming it passes through Haml's filter first, then CoffeeScript compilation.
