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.
