如何使用语法突出显示 zsh 函数的自动建议

我使用 zsh 并编写了一个函数来替换 cd 功能。在一些帮助下，我让它按照我想要的方式工作（大部分）。这是后续我的另一个问题之一 https://stackoverflow.com/questions/64463599/cant-use-in-zsh-autocompletion。 该函数几乎按照我想要的方式工作，但我在语法突出显示和自动完成方面仍然存在一些问题。

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： 我使用语法突出显示，但我输入的路径只是白色（当转到父目录时。正常的 cd 功能是彩色的）。

Example:

$ 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？

这是不可能开箱即用的zsh-syntax-highlighting plugin https://github.com/zsh-users/zsh-syntax-highlighting。它仅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。当为其他有效的命令指定路径参数时，突出显示也会失败，但这些命令不是绝对路径或相对于当前工作目录的有效路径。

例如：

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