zsh - 使用autocad进行首次自动完成

Question

我目前正在从csh切换到zsh我正在写一个.zshrc试图获得我在这个新shell中习惯的所有选项。

我使用autocd（进入一个目录只输入其名称（没有cd命令）），我想知道我是否有可能首先提出当前目录中存在的所有文件（就像它在csh中工作一样）。

我很习惯这样一个概述我可以打开的文件或者我可以“自动”进入的目录，然后在输入命令之前按下我的命令行中没有任何东西。

现在当我第一次按它时不会触发任何完成机制，但它只是写了一个实际的制表。

我还没有找到任何解决方案，如果有人有任何魔术选择来获得这个结果，请随时启发我！

Answer 1

我找到了办法！ 不需要autocd，尽管zsh中存在此选项 放入~/.zshrc：

first-tab() {
    if [[ $#BUFFER == 0 ]]; then
        BUFFER="cd "
        CURSOR=3
        zle list-choices
    else
        zle expand-or-complete
    fi
}
zle -N first-tab
bindkey '^I' first-tab

感谢您提出这个问题：zsh tab completion on empty line

所以按Tab键一次，你就会得到＆＃34; cd＆＃34;和现有的目录。

结帐man zshoptions以查找可能有用的其他现有选项 （setopt menucomplete可能对保存选项卡很有用，但也可以更改其他完成的行为。）

Answer 2

这是另一个更复杂的变体。

• 它将在空命令行和任何命令的中间列出文件。
• 它会在空命令行上列出目录。
• 它会在空命令行上列出可执行文件。

它可以配置为在这些情况下使用全局变量前置“cd”或“./”。

# 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)
