##

# Use fzf as fish completion widget.
|
||||
#
|
||||
#
|
||||
# When FZF_COMPLETE variable is set, fzf is used as completion
|
||||
# widget for the fish shell by binding the TAB key.
|
||||
#
|
||||
# FZF_COMPLETE can have some special numeric values:
|
||||
#
|
||||
# `set FZF_COMPLETE 0` basic widget accepts with TAB key
|
||||
# `set FZF_COMPLETE 1` extends 0 with candidate preview window
|
||||
# `set FZF_COMPLETE 2` same as 1 but TAB walks on candidates
|
||||
# `set FZF_COMPLETE 3` multi TAB selection, RETURN accepts selected ones.
|
||||
#
|
||||
# Any other value of FZF_COMPLETE is given directly as options to fzf.
|
||||
#
|
||||
# If you prefer to set more advanced options, take a look at the
|
||||
# `__fzf_complete_opts` function and override that in your environment.
