#!/usr/bin/env zsh |

# |
||||
# 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. |
