Comments in cjsx

[jonywtf]

Can i use comments in html part of cjsx? Thanks!

Official JSX doesn't support comments and I'm not particularly inclined to add <!-- html style comments --> to CJSX because they would have to be special-cased in the parser.

It would be really nice to have some way of doing this — could we make {# foo } work?

[jsdf]

That wouldn't really make sense. Hash-comments go to the end of the line, so how would we differentiate a curly bracket which is just part of the comment from one which closes a coffeescript expression in JSX markup?

[ConradIrwin]

I would add a special case for when the curly brace is at the end of the line. At the moment it's a syntax error, so it won't break anyone's existing code.

<ul>
  <li />
  {# blah'di'blah}
  <li />
</div>

I've sent a pull request that implements my suggestion above, would love to get some feedback :).

I'm not sure since when, but JSX does seem to support comments: http://facebook.github.io/react/docs/jsx-in-depth.html#comments

Interesting. I'm in favour of implementing comments with the same semantics as JSX

Would love to see the JSX comments added {/* comment */}

[ConradIrwin]

@chasedeanda you can now use {# comment }, which does the same thing :)

Thanks!

Was hoping this would work for commenting multi-line JSX in CoffeeScript 2:

THREE POUND CHARACTERS JSX HERE THREE POUND CHARACTERS

but I get this error:
