zle 命令

常用示例

说明

zle is a builtin command of zsh that controls the Zsh Line Editor, the interactive command-line editing subsystem. It manages widgets (named editing actions), keymaps, display control, and the edit buffer. When called with no arguments, it returns zero if ZLE is currently active. Full documentation is in the zshzle(1) man page. ZLE activates automatically in interactive zsh sessions. It operates in multiline mode (default) or single-line mode (when the SINGLE_LINE_ZLE option is set). Special parameters like BUFFER, CURSOR, LBUFFER, and RBUFFER allow widget functions to manipulate the edit buffer directly.
