ido-mode seems what I wanted. At least it is 99% there.
But, just to clarify, the entries in my list look like:
ActiveRecord::ConnectionAdapters::SchemaStatements#create_table
I wanted to be able to type (or start typing) any of these substrings:
ActiveRecord::ConnectionAdapters::SchemaStatements#create_table
ConnectionAdapters::SchemaStatements#create_table
SchemaStatements#create_table
create_table
So, if I type "creat" and hit tab, it would find
ActiveRecord::ConnectionAdapters::SchemaStatements#create_table
in the list and offer it to me as one of the completions.
I assumed I would have to hook in to the completion process at some point
and was trying to figure out where.
With ido-mode turned on, I am getting a super set of what I wanted but
thats fine. I noticed the ido-mode flag and glanced at the documentation
but it seemed buffer and file specific.
Thanks again for your time.
