zsh 空行上的 Tab 补全

zsh 空行上的 Tab 补全

我想要一个我无法找到的 tcsh'ism：在没有内容的空白行上，我想按 Tab 键并看到相当于 ls 的内容。也就是说我想要

$ <tab>

做其他事情然后给我一个\t。我找到了用于命令完成的出色资源，但不适用于此基本情况。任何对此的帮助都会很棒！谢谢。

答案1

行首处的行为Tab由insert-tab 风格。但是，只有两种受支持的行为：

  • 照常完成，在zstyle ':completion:*' insert-tab false
  • 在下面插入一个选项卡zstyle ':completion:*' insert-tab true
  • 下的一个或另一个zstyle ':completion:*' insert-tab pending[=N]

如果你只是想在那个位置完成命令，zstyle ':completion:*' insert-tab true就可以了。如果您想要不同的东西，例如列出当前目录中的文件，您需要修改_main_complete.

Azsh-workers 列表中的最新主题讨论过insert-tab。

# expand-or-complete-or-list-files
function expand-or-complete-or-list-files() {
    if [[ $#BUFFER == 0 ]]; then
        BUFFER="ls "
        CURSOR=3
        zle list-choices
        zle backward-kill-word
    else
        zle expand-or-complete
    fi
}
zle -N expand-or-complete-or-list-files
# bind to tab
bindkey '^I' expand-or-complete-or-list-files

这是 tcsh 在 zsh 中自动列表的完整实现，当你在空行上按 tab 时

% <TAB>

这里是：

# list dir with TAB, when there are only spaces/no text before cursor,
# or complete words, that are before cursor only (like in tcsh)
tcsh_autolist() { if [[ -z ${LBUFFER// } ]]
    then BUFFER="ls " CURSOR=3 zle list-choices
    else zle expand-or-complete-prefix; fi }
zle -N tcsh_autolist
bindkey '^I' tcsh_autolist

如果您想更紧密地模拟 tcsh，请将其添加到您的 .zshrc 中：

unsetopt always_last_prompt       # print completion suggestions above prompt

我写这zsh 小部件增强了 TAB 的使用，不仅在空行上，而且在您键入命令时也是如此。

  • 它将列出文件on 在空命令行上以及任何命令的中间。
  • 它将列出目录在空命令行上。
  • 它将列出可执行文件在空命令行上。

在这些情况下，可以将其配置为使用全局变量在前面添加“cd”或“./”。

export TAB_LIST_FILES_PREFIX

# Usage:
#   In the middle of the command line:
#     (command being typed)<TAB>(resume typing)
#
#   At the beginning of the command line:
#     <SPACE><TAB>
#     <SPACE><SPACE><TAB>
#
# Notes:
#   This does not affect other completions
#   If you want 'cd ' or './' to be prepended, write in your .zshrc 'export TAB_LIST_FILES_PREFIX'
#   I recommend to complement this with push-line-or edit (bindkey '^q' push-line-or-edit)
