History-Substring-Search
|
||||
========================
|
||||
|
||||
Allows for fish shell-like searching of history with UP and DOWN.
|
||||
|
||||
![example][fish_shell]
|
||||
|
||||
This module requires the [input](https://github.com/Eriner/zim/blob/master/modules/input/README.md) module. Without it, you may experience odd behavior.
|
||||
Put 'input' in the first line and 'history-substring-search' on the second line of `zmodules` in your `.zimrc`.
|
||||
|
||||
Additionally, if you use [syntax-highlighting](https://github.com/Eriner/zim/blob/master/modules/syntax-highlighting/README.md), place 'syntax-highlighting' before 'history-substring-search' on the second line of `zmodules` in your `.zimrc`.
|
||||
|
||||
The options set explicitly by init.zsh are the default options, and are only set for consistancy.
|
||||
|
||||
Functionality is sourced from [history-substring-search](https://github.com/zsh-users/zsh-history-substring-search)

# 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
|
||||
|
||||
|
||||
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.
|
||||
* 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
|
||||
|
||||
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_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.
