⚙️ History search for multiple words

❮ Zi ❯ - History Search Multi Word

Binds Ctrl-R to a widget that searches for multiple keywords in `AND` fashion.

In other words, you can enter multiple words, and history entries that match all of them will be found. The entries are syntax highlighted.

---

Customizing

H-S-MW has feature called context viewing – see all occurrences of a command together with surrounding commands set:

zstyle :plugin:history-search-multi-word reset-prompt-protect 1

Use zle reset-prompt in sched calls, in presence of z-shell/F-Sy-H, zsh-users/zsh-syntax-highlighting, zsh-users/zsh-autosuggestions and other plugins that hook up into Zshell by overloading Zle widgets, e.g.:

PROMPT=%B%F{yellow}%D{%H:%M:%S}%B%b%f
schedprompt() {
  zle && zle reset-prompt
  sched +1 schedprompt
}

zmodload -i zsh/sched
schedprompt

Refresh the clock in prompt every second. The reset-prompt-protect zstyle needs to be set to 1 for correct cooperation with H-S-MW. Or, you could use zle .reset-prompt (i.e. with the dot in front) to call the original, not overloaded (by F-Sy-H, zsh-autosuggestions, etc.) reset-prompt widget.

Zstyles

zstyle ":history-search-multi-word" page-size "8"                      # Number of entries to show (default is $LINES/3)
zstyle ":history-search-multi-word" highlight-color "fg=yellow,bold"   # Color in which to highlight matched, searched text (default bg=17 on 256-color terminals)
zstyle ":plugin:history-search-multi-word" synhl "yes"                 # Whether to perform syntax highlighting (default true)
zstyle ":plugin:history-search-multi-word" active "underline"          # Effect on active history entry. Try: standout, bold, bg=blue (default underline)
zstyle ":plugin:history-search-multi-word" check-paths "yes"           # Whether to check paths for existence and mark with magenta (default true)
zstyle ":plugin:history-search-multi-word" clear-on-cancel "no"        # Whether pressing Ctrl-C or ESC should clear entered query

Syntax highlighting

Syntax highlighting is customized via HSMW_HIGHLIGHT_STYLES associative array. It has keys like reserved-word, alias, command, path, etc. which are assigned with strings like fg=blue,bold, to configure how given elements are to be colored.

If you assign this array before or after loading hsmw you will change the defaults. Complete list of available keys is at the beginning of hsmw-highlight file. Example ~/.zshrc addition that sets path key – paths that exist will be highlighted with background magenta, foreground white, bold:

typeset -gA HSMW_HIGHLIGHT_STYLES
HSMW_HIGHLIGHT_STYLES[path]="bg=magenta,fg=white,bold"

Following code will enable coloring of options of form "-o" and "--option", with cyan:

typeset -gA HSMW_HIGHLIGHT_STYLES
HSMW_HIGHLIGHT_STYLES[single-hyphen-option]="fg=cyan"
HSMW_HIGHLIGHT_STYLES[double-hyphen-option]="fg=cyan"

Following code will use 256 colors to highlight command separators (like ";" or "&&"):

HSMW_HIGHLIGHT_STYLES[commandseparator]="fg=241,bg=17"

Installation

The plugin is "standalone", which means that only sourcing it is needed. So to install, unpack H-S-MW somewhere and add to zshrc:

source {where-hsmw-is}/H-S-MW.plugin.zsh

If using a plugin manager, then Zi is recommended, but you can use any other too, and also install with Oh My Zsh (by copying directory to ~/.oh-my-zsh/custom/plugins).

Zi

Add zi load z-shell/H-S-MW to your .zshrc file. Zi will handle cloning the plugin for you automatically the next time you start zsh.

Zinit

Add zinit load z-shell/H-S-MW to your .zshrc file.

Antigen

Add antigen bundle z-shell/H-S-MW to your .zshrc file. Antigen will handle cloning the plugin for you automatically the next time you start zsh. You can also add the plugin to a running zsh with antigen bundle z-shell/H-S-MW for testing before adding it to your .zshrc.

Oh-My-Zsh

1. cd ~/.oh-my-zsh/custom/plugins
2. git clone [e-mail]:z-shell/H-S-MW.git
3. Add H-S-MW to your plugin list

Zgen

Add zgen load z-shell/H-S-MW to your .zshrc file in the same place you're doing your other zgen load calls in.

1. Start a new terminal session
