zsh-history-substring-search | ||
============================================================================== | ||
|
||
This is a clean-room implementation of the [Fish shell][1]'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. | ||
You can also use K and J in VI mode or ^P and ^N in EMACS mode for the same. | ||

||
------------------------------------------------------------------------------ | ||
Requirements | ||
------------------------------------------------------------------------------ | ||
|
||
* [ZSH](http://zsh.sourceforge.net) 4.3 or newer | ||
|
||
------------------------------------------------------------------------------ | ||
Usage | ||
------------------------------------------------------------------------------ | ||
|
||
1. Load this script into your interactive ZSH session: | ||
|
||
% source zsh-history-substring-search.zsh | ||
|
||
If you want to use [zsh-syntax-highlighting][6] along with this script, | ||
then make sure that you load it *before* you load this script: | ||
|
||
% source zsh-syntax-highlighting.zsh | ||
% source zsh-history-substring-search.zsh | ||
|
||
2. Bind keyboard shortcuts to this script's functions: | ||
|
||
# bind UP and DOWN arrow keys | ||
zmodload zsh/terminfo | ||
bindkey "$terminfo[kcuu1]" history-substring-search-up | ||
bindkey "$terminfo[kcud1]" history-substring-search-down | ||
|
||
# bind UP and DOWN arrow keys (compatibility fallback | ||
# for Ubuntu 12.04, Fedora 21, and MacOSX 10.9 users) | ||
bindkey '^[[A' history-substring-search-up | ||
bindkey '^[[B' history-substring-search-down | ||
|
||
# bind P and N for EMACS mode | ||
bindkey -M emacs '^P' history-substring-search-up | ||
bindkey -M emacs '^N' history-substring-search-down | ||
|
||
# bind k and j for VI mode | ||
bindkey -M vicmd 'k' history-substring-search-up | ||
bindkey -M vicmd 'j' history-substring-search-down | ||
|
||
3. 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. | ||
|
||
4. 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. | ||
|
||
To always receive _unique_ search results, use `setopt HIST_IGNORE_ALL_DUPS`. | ||
Alternatively, use `setopt HIST_FIND_NO_DUPS` which makes this plugin skip | ||
duplicate _adjacent_ search results as you cycle through them---however, this | ||
does not guarantee that search results are unique: if your search results were | ||
"Dog", "Dog", "HotDog", "Dog", then cycling them gives "Dog", "HotDog", "Dog". | ||
Notice that the "Dog" search result appeared twice as you cycled through them! | ||
If you wish to avoid this limitation, then use `setopt HIST_IGNORE_ALL_DUPS`. | ||
|

History | ||
------------------------------------------------------------------------------ | ||
|
||
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 project][3] in January 2011. | ||
|
||
It was later extracted from fizsh 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. | ||

Oh My Zsh Distribution Notes | ||
------------------------------------------------------------------------------ | ||
|
||
What you are looking at now is Oh My Zsh's repackaging of zsh-history-substring-search | ||
as an OMZ module inside the Oh My Zsh distribution. | ||
|
||
The upstream repo, zsh-users/zsh-history-substring-search, can be found on GitHub at | ||
https://github.com/zsh-users/zsh-history-substring-search. | ||
|
||
This downstream copy was last updated from the following upstream commit: | ||
|
||
SHA: 2c295432175990c1bb4e90bc13f609daa67a25d6 | ||
Commit date: 2015-09-28 10:47:34 -0700 | ||
|
||
Everything above this section is a copy of the original upstream's README, so things | ||
may differ slightly when you're using this inside OMZ. In particular, you do not | ||
need to set up key bindings for the up and down arrows yourself in `~/.zshrc`; the OMZ | ||
plugin does that for you. You may still want to set up additional emacs- or vi-specific | ||
bindings as mentioned above. | ||
