Context filename

[tmpfs]

This fixes an issue where setting options.root to the filename context (https://github.com/reshape/layouts/blob/master/lib/index.js#L8) would override use of the context filename on subsequent requests to resolve layouts when no root option is given.

For example, by assigning the context filename to options.root (when no root option is specified) it would never be called again - the root is set to the first file processed and used by all subsequent files.

This ensures all layouts are resolved correctly when no root option is given.

Also updated the .gitignore for the code coverage output directory.

Awesome, thank you for the contribution! Is there any chance you could add a test case to ensure this doesn't end up being missed by any future changes?

Hey,

I have looked into adding a test case, however I am not sure how to go about configuring the test specs/fixtures as we need to be able to pass multiple context filenames in a single pass to be sure that the dirname() for subsequent requests is used as the root.

Suggestions?

So what was the original way you were using it that inspired you to make this fix in the first place? Running something like this is a pretty reliable way to ensure that it's working now 😁
