问题描述

我使用 zsh 并编写了一个函数来替换 cd 函数。在一些帮助下,我让它像我想要的那样工作(大部分)。这是我的另一个问题之一的后续行动。该功能几乎可以像我想要的那样工作,但我仍然在语法突出显示和自动完成方面遇到一些问题。

对于示例,假设您的目录如下所示:

/
    a/
        b/
        c/
            d/
        some_dir/

我还假设已获取以下代码:

cl () {
    local first=$( echo $1 | cut -d/ -f1 )
    if [ -d $first ]; then
        pushd $1 >/dev/null # If the first argument is an existing normal directory, move there
    else
        pushd ${PWD%/$first/*}/$1 >/dev/null # Otherwise, move to a parent directory or a child of that parent directory
    fi
}
_cl() {
    _cd
    pth=${words[2]}
    opts=""
    new=${pth##*/}
    local expl
    # Generate the visual formatting and store it in `$expl`
    _description -V ancestor-directories expl 'ancestor directories'
    [[ "$pth" != *"/"*"/"* ]] && middle="" || middle="${${pth%/*}#*/}/"
    if [[ "$pth" != *"/"* ]]; then
        # If this is the start of the path
        # In this case we should also show the parent directories
        local ancestor=$PWD:h
        while (( $#ancestor > 1 )); do
            # -f: Treat this as a file (incl. dirs), so you get proper highlighting.
            # -Q: Don't quote (escape) any of the characters.
            # -W: Specify the parent of the dir we're adding.
            # ${ancestor:h}: The parent ("head") of $ancestor.
            # ${ancestor:t}: The short name ("tail") of $ancestor.
            compadd "$expl[@]" -fQ -W "${ancestor:h}/" - "${ancestor:t}"
            # Move on to the next parent.
            ancestor=$ancestor:h
        done
    else
        # $first is the first part of the path the user typed in.
        # it it is part of the current direoctory, we know the user is trying to go back to a directory
        first=${pth%%/*}
        # $middle is the rest of the provided path
        if [ ! -d $first ]; then
            # path starts with parent directory
            dir=${PWD%/$first/*}/$first
            first=$first/
            # List all sub directories of the $dir/$middle directory
            if [ -d "$dir/$middle" ]; then
                for d in $(ls -a $dir/$middle); do
                    if [ -d $dir/$middle/$d ] && [[ "$d" != "." ]] && [[ "$d" != ".." ]]; then
                        compadd "$expl[@]" -fQ -W $dir/ - $first$middle$d
                    fi
                done
            fi
        fi
    fi
}
compdef _cl cl

问题:我使用语法高亮,但我输入的路径只是白色的(当转到父目录时。正常的 cd 函数是彩色的)。

例子:

$ cd /a
$ cl c # 'c' is colored
$ pwd
/a/c
$ cl a/b # 'a/b' is not colored
$ cl a/[tab] # 'a/b', 'a/c' and 'a/some_dir' are not colored

如何让这些路径着色?

解决方案


zsh-syntax-highlighting使用插件开箱即用是不可能的。它只检查您输入的内容是否是

  • A)有效的绝对路径或
  • B)相对于当前工作目录的有效路径。

这不是特定于您的命令。为其他有效但不是绝对路径或相对于当前工作目录的有效路径的其他命令指定路径参数时,突出显示也会失败。

例如:

% cd /a/b
% cd b c  # perfectly valid args, but will not get highlighted as valid paths
% pwd
/a/c
