Incremental search for zsh

Move cursor with incremental search within current line.

CAVEATS

This plugin is the reinvention of the zsh's builtin feature ^R and ^S. These commands also allow you to move the cursor within the current line, though the name history-incremental-search is not obvious that they has the capability.

Configuration

To your ~/.zshrc:

# bind to any keys you like
bindkey "^[l" incsearch-forward              # put cursor at the end of match
bindkey "^[h" incsearch-backward             # put cursor at the end of match
bindkey "^[L" incsearch-forward-beginning    # put cursor at the beginning of match
bindkey "^[H" incsearch-backward-beginning   # put cursor at the beginning of match

my_incsearch_hook_enter() {
    if [ "$TERM_PROGRAM" = "iTerm.app" ]; then
        # Change cursor to underline
        echo -ne "\e]50;CursorShape=2\a"
    fi
}

my_incsearch_hook_leave() {
    if [ "$TERM_PROGRAM" = "iTerm.app" ]; then
        # Restore cursor to block
        echo -ne "\e]50;CursorShape=0\a"
    fi
}

incsearch_hooks_enter+="my_incsearch_hook_enter"
incsearch_hooks_leave+="my_incsearch_hook_leave"
