[GNC-dev] Ideas for account type-ahead modification

[jean]

I gave that a shot. See

But see comments below:

> Imagine we have the following account tree:
 >
> Assets:Cash
> Assets:Bank
> Income:Salary
> Expenses:Bets
> Expenses:Bets:Blue
> 
> Typing 'et' will filter the list of accounts to show to
> 
> Assets:Cash
> Assets:Bank
> Expenses:Bets
> Expenses:Bets:Blue
> 
> Subsequently typing ":" will autocomplete 'et' to 'ets:' and reduce the list to >
> Assets:Cash
> Assets:Bank
> Expenses:Bets:Blue

I haven't implemented the autocomplete because in most cases I"m not 
sure what to do:

What if you have:

Assets:Cash
Expenses:Bets
Forgeta:Foo

All three match "et" but what do we do if the user type ":" ? In which 
situation can we autocomplete? In the current search, ":" autocompletes 
the current match (i.e., it moves the cursor to the next :). But in the 
mixed search, it's not clear what it should do.
Should I treat ":" as .*: (non greedy) in regexp? I think that would be 
pretty cool and it would be consistent with the legacy behavior.

In any case, the merging of the two searches actually does work 
currently and is fairly intuitive. So if you guys like this solution 
then I could remove the option, which would be really good!
