spelling correction bug?

spelling correction bug?

[Dominik Vogt]

I have my zsh-4.0.4 configured for spelling correction:

  setopt CORRECT
  unsetopt CORRECT_ALL

(not using the new completion system yet).  Now, when I type

  $ mape all

zsh asks

  zsh: correct 'mape' to 'mpage' [nyae]? 

But "mpage" is two character errors away from "mape", while "make"
is only one error away.  Shouldn't it try closer matches first?

Ciao

This sort of correction (unlike that in the completion system) is
actually based on the keyboard layout; that's why there's an option
DVORAK to use the Dvorak keyboard.   Hence it decides `k' isn't near
enough to `p' for you to have meant that, whereas you might (without
reference to the keyboard) have missed out a letter or transposed a
couple.

There's a long-standing wish that you could use completion-style
correction at this point, but it's a lot of work.  With Sven absent,
it's not even clear there's anyone capable of doing it at the moment.

Thanks for the quick answer.  Actually I have been considering to
give up my work on fvwm and instead take a look at the zsh sources
:-)
