Error event indexOf #33

Closed stephenway closed 8 years ago

stephenway commented 8 years ago

This is an error I get when I try to run this plugin in my gulp postcss processors. Unsure of if this is related to any other issues, but it's definitely blocking me.

@stephenway Can you share the input? Something reproducible in the sandbox would be great, https://madlittlemods.github.io/postcss-css-variables/playground/

Unfortunately I am unable to pinpoint where it fails right now, but I know that this error only occurs when a variable doesn't have a definition in root. My next step is to just comment large portions of my code out to see where its happening.

Side-note, it would help me if I knew where it was breaking via the error message. Do you have plans to change error reporting?

@stephenway Probably related to https://github.com/MadLittleMods/postcss-css-variables/issues/22

Yea as I'm working through my partials I'm seeing that it's just issues with inheritance that need to get worked out. Thanks!
