# 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 command from history and then
|
||
press chosen keys, such as the UP and DOWN arrows, to cycle through matches.

Requirements
|
||
------------------------------------------------------------------------------
|
||
|
||
* [ZSH](http://zsh.sourceforge.net) 4.3 or newer
|
||
|
||
Install
|
||
------------------------------------------------------------------------------
|
||
|
||
Using the [Homebrew]( https://brew.sh ) package manager:
|
||
|
||
brew install zsh-history-substring-search
|
||
echo 'source /usr/local/share/zsh-history-substring-search/zsh-history-substring-search.zsh' >> ~/.zshrc
|
||
|
||
Using [Oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh):
|
||
|
||
1. Clone this repository in oh-my-zsh's plugins directory:
|
||
|
||
git clone https://github.com/zsh-users/zsh-history-substring-search ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-history-substring-search
|
||
|
||
2. Activate the plugin in `~/.zshrc`:
|
||
|
||
plugins=( [plugins...] history-substring-search)
|
||
|
||
3. Source `~/.zshrc` to take changes into account:
|
||
|
||
source ~/.zshrc
|
||
|
||
Usage
|
||
------------------------------------------------------------------------------
|
||
|
||
1. Load this script into your interactive ZSH session:
|
||
|
||
% source zsh-history-substring-search.zsh
|
||
|
||
If you want to use [zsh-syntax-highlighting][6] along with this script,
|
||
then make sure that you load it *before* you load this script:
|
||
|
||
% source zsh-syntax-highlighting.zsh
|
||
% source zsh-history-substring-search.zsh
|
||
|
||
2. Bind keyboard shortcuts to this script's functions.
|
||
|
||
Users typically bind their UP and DOWN arrow keys to this script, thus:
|
||
* Run `cat -v` in your favorite terminal emulator to observe key codes.
|
||
(**NOTE:** In some cases, `cat -v` shows the wrong key codes. If the
|
||
key codes shown by `cat -v` don't work for you, press `<C-v><UP>` and
|
||
`<C-v><DOWN>` at your ZSH command line prompt for correct key codes.)
|
||
* Press the UP arrow key and observe what is printed in your terminal.
|
||
* Press the DOWN arrow key and observe what is printed in your terminal.
|
||
* Press the Control and C keys simultaneously to terminate the `cat -v`.
|
||
* Use your observations from the previous steps to create key bindings.
|
||
For example, if you observed `^[[A` for UP and `^[[B` for DOWN, then:
|
||
|
||
bindkey '^[[A' history-substring-search-up
|
||
bindkey '^[[B' history-substring-search-down
|
||
|
||
However, if the observed values don't work, you can try using terminfo:
|
||
|
||
bindkey "$terminfo[kcuu1]" history-substring-search-up
|
||
bindkey "$terminfo[kcud1]" history-substring-search-down
|
||
|
||
You might also want to bind the Control-P/N keys for use in EMACS mode:
|
||
|
||
bindkey -M emacs '^P' history-substring-search-up
|
||
bindkey -M emacs '^N' history-substring-search-down
|
||
|
||
You might also want to bind the `k` and `j` keys for use in 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 `history-substring-search-up` key, which was configured in
|
||
step 2 above, to select the nearest command that (1) contains your query
|
||
and (2) is also older than the current command in your command history.
|
||
|
||
* Press the `history-substring-search-down` key, which was configured in
|
||
step 2 above, to select the nearest command that (1) contains your query
|
||
and (2) is also newer than the current command in your 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 `history-substring-search-up` key, which was configured in
|
||
step 2 above, to move the cursor to the line above the cursored line.
|
||
When the cursor reaches the first line of the command, pressing the
|
||
`history-substring-search-up` key again will cause this script to
|
||
perform another search.
|
||
|
||
* Press the `history-substring-search-down` key, which was configured in
|
||
step 2 above, to move the cursor to the line below the cursored line.
|
||
When the cursor reaches the last line of the command, pressing the
|
||
`history-substring-search-down` key, which was configured in step 2
|
||
above, 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.
|
||
|
||
* `HISTORY_SUBSTRING_SEARCH_FUZZY` is a global variable that defines
|
||
how the command history will be searched for your query. If set to a non-empty
|
||
value, causes this script to perform a fuzzy search by words, matching in
|
||
given order e.g. `ab c` will match `*ab*c*`
|
||
|
||
* `HISTORY_SUBSTRING_SEARCH_ENSURE_UNIQUE` is a global variable that defines
|
||
whether all search results returned are _unique_. If set to a non-empty
|
||
value, then only unique search results are presented. This behaviour is off
|
||
by default. An alternative way to ensure that search results are unique is
|
||
to use `setopt HIST_IGNORE_ALL_DUPS`. If this configuration variable is off
|
||
and `setopt HIST_IGNORE_ALL_DUPS` is unset, then `setopt HIST_FIND_NO_DUPS`
|
||
is still respected and it makes this script skip duplicate _adjacent_ search
|
||
results as you cycle through them, but 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
|
||
receive globally unique search results only once, then use this
|
||
configuration variable, or use `setopt HIST_IGNORE_ALL_DUPS`.
|
||
|
||
|
||
History
|
||
------------------------------------------------------------------------------
|
||
|
||
* September 2009: [Peter Stephenson][2] originally wrote this script and it
|
||
published to the zsh-users mailing list.
|
||
|
||
* January 2011: Guido van Steen (@guidovansteen) revised this script and
|
||
released it under the 3-clause BSD license as part of [fizsh][3], the
|
||
Friendly Interactive ZSHell.
|
||
|
||
* January 2011: Suraj N. Kurapati (@sunaku) extracted this script from
|
||
[fizsh][3] 1.0.1, refactored it heavily, and finally repackaged it as an
|
||
[oh-my-zsh plugin][4] and as an independently loadable [ZSH script][5].
|
||
|
||
* July 2011: Guido van Steen, Suraj N. Kurapati, and Sorin Ionescu
|
||
(@sorin-ionescu) [further developed it][4] with Vincent Guerci (@vguerci).
|
||
|
||
* March 2016: Geza Lore (@gezalore) greatly refactored it in pull request #55.

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: 0f80b8eb3368b46e5e573c1d91ae69eb095db3fb
|
||
Commit date: 2019-05-12 17:35:54 -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.
