Operations
{ANY}
  • to_absolute
    Transform into equivalent absolute path
  • normalize_case
    Transform into normalized case version (equivalent), with standard path separators
  • normalize
    Normalize removing double separators, and up-references
  • remove_last
    Remove last component of path (keep the "dirname")
  • add_last (elem: STRING)
  • join (other: PATH_NAME)
    Join with other using filesystem semantics

{PATH_JOINER}
{}
  • tmp: UNIXISH_PATH_NAME
{PATH_JOINER}
  • start_join (drive: STRING, absoluteness: INTEGER_32)
    Start joining an absolute path to Current
    drive is optional absoluteness is, e.g., the number of leading slashes:
      0 for relative paths
      1 for absolute paths
      more for super-absolute paths (for instance, network-wide)
    
  • join_directory (element: STRING)
    Add a directory to the end of the path
  • join_file (element: STRING)
    Add a file to the end of the path
