Bug #3126
closed
irb/completionでTypeError
Description
=begin
irb/completion を読み込んでいると「a.」や「C::」などの後にタブキーを押すと
.../irb/completion.rb:137:in quote': can't convert NilClass to String (TypeError) や .../irb/completion.rb:87:in quote': can't convert NilClass to String (TypeError)
で終了してしまいます。
以下の修正で直るようです。
