python -m 模块的命令行自动补全

Hat*_*sut 12 python bash autocomplete bash-completion

是否有可能获得命令行自动完成功能python -m package.subpackage.module

这类似于但不一样,python ./package/subpackage/module.py它会自动完成目录和文件路径。但是-m,使用 时,python 将库的模块作为具有适当命名空间和导入路径的脚本来运行。

我希望能够python -m package.s[TAB]自动完成subpackage.

此功能是否内置于某处,或者我该如何设置?

正如评论部分所述,您需要扩展bash-completion工具。然后,您将创建一个脚本来处理您需要的情况(即:当最后一个参数为 时-m)。

下面的这个小示例显示了自定义完成脚本的开始。我们来命名一下吧python_completion.sh

_python_target() {
    local cur prev opts

    # Retrieving the current typed argument
    cur="${COMP_WORDS[COMP_CWORD]}"

    # Retrieving the previous typed argument ("-m" for example)
    prev="${COMP_WORDS[COMP_CWORD-1]}"

    # Preparing an array to store available list for completions
    # COMREPLY will be checked to suggest the list
    COMPREPLY=()

    # Here, we'll only handle the case of "-m"
    # Hence, the classic autocompletion is disabled
    # (ie COMREPLY stays an empty array)
    if [[ "$prev" != "-m" ]]
    then
        return 0
    fi

    # Retrieving paths and converts their separators into dots
    # (if packages doesn't exist, same thing, empty array)
    if [[ ! -e "./package" ]]
    then
       return 0
    fi

    # Otherwise, we retrieve first the paths starting with "./package"
    # and converts their separators into dots
    opts="$(find ./package -type d | sed -e 's+/+.+g' -e 's/^\.//' | head)"

    # We store the whole list by invoking "compgen" and filling
    # COMREPLY with its output content.
    COMPREPLY=($(compgen -W "$opts" -- "$cur"))

}

(警告。此脚本有一个缺陷,它不适用于包含空格的文件名)。要测试它,请在当前环境中运行它:

是一个以这种方式继续的教程。
