TypeError: undefined is not a function #83

Does somebody has any idea about what could be causing this error?

try double quotes around your attributes instead of single quotes; that fixed it for me

ypresto commented 9 years ago

I really want to use single quote because haml-lint gem, which uses rubocop syntax checker, warns about it.

RuboCop: Style/StringLiterals: Prefer single-quoted strings when you don't need string interpolation or special symbols.
Juanmcuello commented 9 years ago

Same problem here using single quotes. Using double quotes fixes the issue, but that's not an option for me.

soyuka commented 9 years ago

Same issue here,

after investigation (I'm using gulp-haml), when render is called, escaperName is undefined.

A quick fix is to add escaperName = "html_escape"; in the render function or to the variable declaration.

@soyuka

Ahh, I understand. This library seems to support only JSON in attributes.

https://github.com/creationix/haml-js/blob/master/lib/haml.js#L27

I think automatically replacing ' to " (of course "s inside of it too) if possible will be better for performance. Then skip parse_interpol.

ypresto commented 9 years ago

Just adding single quote test doesn't cause the exception (still not optimized js is generated). It might be issue on gulp side.

This project seems to be discontinued, isn't it? @aaronblohowiak
