|
# This is a clean-room implementation of the Fish[1] shell's history search
|
|
# feature, where you can type in any part of any previously entered command
|
|
# and press the UP and DOWN arrow keys to cycle through the matching commands.
|
|
#
|
|
#-----------------------------------------------------------------------------
|
|
# Usage
|
|
#-----------------------------------------------------------------------------
|
|
#
|
|
# 1. Load this script into your interactive ZSH session:
|
|
#
|
|
# % source history-substring-search.zsh
|
|
#
|
|
# If you want to use the zsh-syntax-highlighting[6] script along with this
|
|
# script, then make sure that you load it *before* you load this script:
|
|
#
|
|
# % source zsh-syntax-highlighting.zsh
|
|
# % source history-substring-search.zsh
|
|
#
|
|
# 2. Type any part of any previous command and then:
|
|
#
|
|
# * Press the UP arrow key to select the nearest command that (1) contains
|
|
# your query and (2) is older than the current command in the command
|
|
# history.
|
|
#
|
|
# * Press the DOWN arrow key to select the nearest command that (1)
|
|
# contains your query and (2) is newer than the current command in the
|
|
# command history.
|
|
#
|
|
# * Press ^U (the Control and U keys simultaneously) to abort the search.
|
|
#
|
|
# 3. If a matching command spans more than one line of text, press the LEFT
|
|
# arrow key to move the cursor away from the end of the command, and then:
|
|
#
|
|
# * Press the UP arrow key to move the cursor to the line above. When the
|
|
# cursor reaches the first line of the command, pressing the UP arrow
|
|
# key again will cause this script to perform another search.
|
|
#
|
|
# * Press the DOWN arrow key to move the cursor to the line below. When
|
|
# the cursor reaches the last line of the command, pressing the DOWN
|
|
# arrow key again will cause this script to perform another search.
|
|
#
|
|
#-----------------------------------------------------------------------------
|
|
# Configuration
|
|
#-----------------------------------------------------------------------------
|
|
#
|
|
# This script defines the following global variables. You may override their
|
|
# default values only after having loaded this script into your ZSH session.
|
|
#
|
|
# * HISTORY_SUBSTRING_SEARCH_HIGHLIGHT_FOUND is a global variable that defines
|
|
# how the query should be highlighted inside a matching command. Its default
|
|
# value causes this script to highlight using bold, white text on a magenta
|
|
# background. See the "Character Highlighting" section in the zshzle(1) man
|
|
# page to learn about the kinds of values you may assign to this variable.
|
|
#
|
|
# * HISTORY_SUBSTRING_SEARCH_HIGHLIGHT_NOT_FOUND is a global variable that
|
|
# defines how the query should be highlighted when no commands in the
|
|
# history match it. Its default value causes this script to highlight using
|
|
# bold, white text on a red background. See the "Character Highlighting"
|
|
# section in the zshzle(1) man page to learn about the kinds of values you
|
|
# may assign to this variable.
|
|
#
|
|
# * HISTORY_SUBSTRING_SEARCH_GLOBBING_FLAGS is a global variable that defines
|
|
# how the command history will be searched for your query. Its default value
|
|
# causes this script to perform a case-insensitive search. See the "Globbing
|
|
# Flags" section in the zshexpn(1) man page to learn about the kinds of
|
|
# values you may assign to this variable.

# This script was originally written by Peter Stephenson[2], who published it
|
|
# to the ZSH users mailing list (thereby making it public domain) in September
|
|
# 2009. It was later revised by Guido van Steen and released under the BSD
|
|
# license (see below) as part of the fizsh[3] project in January 2011.
|
|
#
|
|
# It was later extracted from fizsh[3] release 1.0.1, refactored heavily, and
|
|
# repackaged as both an oh-my-zsh plugin[4] and as an independently loadable
|
|
# ZSH script[5] by Suraj N. Kurapati in 2011.
|
|
#
|
|
# It was further developed[4] by Guido van Steen, Suraj N. Kurapati, Sorin
|
|
# Ionescu, and Vincent Guerci in 2011.
