# Menu-driven alternative to history-beginning-search-backward.
|
|
# As it uses a menu there is no sense of "forward" or "backward", however;
|
|
# the entire history is searched.
|
|
#
|
|
# Configuration:
|
|
# autoload -Uz history-beginning-search-menu
|
|
# zle -N history-beginning-search-menu
|
|
# bindkey '\eP' history-beginning-search-menu
|
|
#
|
|
# Example:
|
|
# % /bin/su<ESC-P>
|
|
# Enter digit:
|
|
# 1 /bin/su -c 'make install' 4 /bin/su - perforce
|
|
# 2 /bin/su 5 /bin/su -c
|
|
# 3 /bin/su -c 'chown pws:pws **/*(u0)'
|
|
#
|
|
# Typing "1" expands the line to
|
|
# % /bin/su -c 'make install'
|
|
#
|
|
# With a prefix argument, the search is not anchored to the beginning,
|
|
# so for example "/su" could expand to "p4 files //depot/support/..."
|
|
#
|
|
# If this is bound to a widget containing "-end", e.g.
|
|
# zle -N history-beginning-search-menu-end history-beginning-search-menu
|
|
# then the cursor is put at the end of the line, else it is left
|
|
# after the matched characters.
|
|
#
|
|
# If this is bound to a widget containing "-space", then any space in
|
|
# the line so far is matched as a wildcard. (This means putting a space
|
|
# at the start of the line is equivalent to specifying a prefix
|
|
# argument.)
