Allow fuzzy filters before completion is invoked about fzf-tab HOT 2 CLOSED

This is an interesting idea, but it is beyond fzf-tab's ability currently. fzf-tab only shows your result, it doesn't do the match.

But this can be done by zsh itself. Here is a zstyle which is your want:

# 0 -- vanilla completion (abc => abc)
# 1 -- smart case completion (abc => Abc)
# 2 -- word flex completion (abc => A-big-Car)
# 3 -- full flex completion (abc => ABraCadabra)
zstyle ':completion:*' matcher-list '' \
  'm:{a-z\-}={A-Z\_}' \
  'r:[^[:alpha:]]||[[:alpha:]]=** r:|=* m:{a-z\-}={A-Z\_}' \
  'r:|?=** m:{a-z\-}={A-Z\_}'

from fzf-tab.

Emmm, after half a day of trial I found the zstyle above is too fuzzy.

Here may be a better solution, only smart case completion and word flex completion:

zstyle ':completion:*' matcher-list '' \
  'm:{[:lower:]-}={[:upper:]_}' \
  'r:|[.,_-]=* r:|=*'

In your example, you can use a-b-c to match alpha-bravo-charlie.
