    Function commonPathTransform

    • replace the common path among all provided paths by transforming it with a custom map_fn function. all paths are initially normalized and converted into posix-style (so that no "\" windows separator is prevelent).

      the map_fn function's first argument (path_info), is a 2-tuple of the form [common_dir: string, subpath: string], where common_dir represents the directory common to all of the input paths, and the subpath represents the remaining relative path that comes after common_dir.

      • the common_dir always ends with a trailing slash ("/"), unless there is absolutely no common directory among the paths at all.
      • the subpath never begins with any slash (nor any dot-slashes), unless of course, you had initially provided a path containing two or more consecutive slashes.

      Type Parameters

      • T = string
      • PathInfo extends [common_dir: string, subpath: string] = [common_dir: string, subpath: string]

      Parameters

      • paths: string[]
      • map_fn: (path_info: PathInfo, index: number, path_infos: PathInfo[]) => T

      Returns T[]
