Looks like the lexer has changed a bit, and the strings are parsed differently now in CoffeeScript.

coffee -t -e "\"#{2}/\""
[STRING_START (] [( (] [NUMBER 2] [) )] [+ +] [STRING "/"] [STRING_END )] [TERMINATOR \n]

iced -t -e "\"#{1}/\""
[( (] [STRING ""] [+ +] [NUMBER 1] [+ +] [STRING "/"] [) )] [TERMINATOR \n]

I tried to swap grammar and lexer from latest CoffeeScript to IcedCoffeeScript but the changes are too significant for me to cherry pick things and apply.

How about ICS version 3?

iced3 is already on the new grammar/lexer so it works there.

iced -v IcedCoffeeScript version 108.0.9 still reproduced. Where can i find iced3?

[zapu]

It is still work in progress, unfortunately. You can follow this PR if you are interested: https://github.com/maxtaco/coffee-script/pull/168

@vird may I ask what's your use case? Would you be able to test new iced3, even by just installing it in test environment and running your application's test suite against it? Thanks

[vird]

@zapu I use iced for generating opencl kernels source code. So I have code something like this

code = """
  int offset = size_x + #{other_offset/2}; // comment
  """

btw. What's a proper method for install iced3? I download branch. I can use ./bin/coffee but i don't know how to install globally.
