searching words in history similar to insert-last-word

[Dominik Vogt]

Hi folks,

I'm looking for a way to complete the last word I'm typing on the command
line by doing a history search.  With Alt-. (insert-last-word) I can browse
through the last words of the previous lines, but I'm looking for something
more clever.  My use case is this:

I'm copying files to remote machines with scp, e.g.

  $ scp foo user@machine1.domain:
  $ scp bar baz .* user@machine2.domain:

I'd like to be able to simplify this by being able to type

  $ scp xyz user@<SHIFT-UP><SHIFT-UP>

to yield

  $ scp xyz user@machine1.domain:

When I press <SHIFT-UP> repeatedly, zsh should replace the last word on the
line with words from the history that begin with "user@".  The function
name might be something like "beginning-search-up".  Some extra features
or options would be:

1. Ignore the first word of each line but look through all other words
   on each history line.
2. (If the word that is to be completed is the first word on the line,
   only consider the first word of all history lines.)
3. Allow searching in the other direction with <SHIFT-DOWN>.

And as a related but seperate issue:

How can I make a function that works like insert-last-word but works in the
opposite direction (insert-next-word).  This would of course only be
usefull if I use insert-last-word first.

Ciao

_insert_next_word () {
        zle .insert-last-word 1 -1
}
zle -N insert-next-word _insert_next_word

zstyle ':completion:history-words:*' remove-all-dups yes

You might also want

zstyle ':completion:history-words:*' sort yes

Great, that's almost exactly what I was looking for.  Is there a way to get
rid of the duplicates though?  I get a list of matching words like this:

  user@machine1 user@machine2 user@machine1 user@machine2 ...

instead of just

  user@machine1 user@machine2

Perfect, thank you very much.  :-)
