# smart-insert-last-word
|
|
# Inspired by Christoph Lange <langec@gmx.de> from zsh-users/3265;
|
|
# rewritten to correct multiple-call behavior after zsh-users/3270;
|
|
# modified to work with copy-earlier-word after zsh-users/5832.
|
|
#
|
|
# This function as a ZLE widget can replace insert-last-word, like so:
|
|
#
|
|
# zle -N insert-last-word smart-insert-last-word
|
|
#
|
|
# With a numeric prefix, behaves like insert-last-word, except that words
|
|
# in comments are ignored when interactive_comments is set.
|
|
#
|
|
# Otherwise, the rightmost "interesting" word from the previous command is
|
|
# found and inserted. The default definition of "interesting" is that the
|
|
# word contains at least one alphabetic character, slash, or backslash.
|
|
# This definition can be overridden by use of a style like so:
|
|
#
|
|
# zstyle :insert-last-word match '*[[:alpha:]/\\]*'
|
|
#
|
|
# For example, you might want to include words that contain spaces:
|
|
#
|
|
# zstyle :insert-last-word match '*[[:alpha:][:space:]/\\]*'
|
|
#
|
|
# Or include numbers as long as the word is at least two characters long:
|
|
#
|
|
# zstyle :insert-last-word match '*([[:digit:]]?|[[:alpha:]/\\])*'
|
|
#
|
|
# That causes redirections like "2>" to be included.
|
|
#
|
|
# Note also that the style is looked up based on the widget name, so you
|
|
# can bind this function to different widgets to use different patterns:
|
|
#
|
|
# zle -N insert-last-assignment smart-insert-last-word
|
|
# zstyle :insert-last-assignment match '[[:alpha:]][][[:alnum:]]#=*'
|
|
# bindkey '\e=' insert-last-assignment
|
|
