NoMethodError: undefined method `values' for nil:NilClass

    from /home/trans/.rbfu/rubies/1.9.3-p0/bin/irb:12:in `<main>'

Since there are no modules in this case, I would expect it to return an empty array (preferably). But since there are none, the @classes attribute in RDoc::Context is nil instead of a Hash, so when #values is called against it, this error occurs.

What is the source used to generate the ri data store?

trans commented Mar 7, 2012

I've been using this sample project:

I generate with:

$ rdoc --ri --op .rdoc lib README

Note, I've also noticed a few other issues, for example, #line seems to always returns nil and constants have no value and classes/modules don't have #file or #in_files. I was going to report these once I double checked them, but I'll just mention them presently. If you'd rather I file additional issues let me know.

This has been fixed in RDoc 4, but RDoc::Store#modules no longer exists. Use #module_names instead.
