MakeDir.lua

-- MakeDir.lua (cross-platform)
-- 2024.11.16
--
-- Creating directory(ies) with additional features.
--[[
1. You can use absolute name (/path/to/newdir), relative to current path (to/newdir) or only name (newdir).
  Script will also create all directories leading up to the entered name(s) that do not exist already.
2. If you want more one dir at once then use vertical bar:
  newdir1|newdir2|newdir3
3. All space characters (usual space characters) at the beginning or end of the name(s) will be deleted.
4. You can use some variables:
    <dt> - current date and time: YYYYMMDDhhmmss;
    <d> or <t> - current date (YYYYMMDD) or time (hhmmss);
    <y> - current year, 4 digits;
    <fdt>, <fd>, <ft> and <fy> - like previouses, but from file under cursor (last modified date/time);
    <p> - parent folder from current directory;
    <x-y> - multiple folder creation with counter. Width depends on y.
    For example: "name<1-15>" means 15 folders: "name01", "name02", ... "name15".
  Note: You can use more then one variable in each name.
5. Use "<c>" to get the names from the clipboard.
6. If the first symbol is ":" (without quotes), this script will open the first directory.

Params:
  %"0%D
  %"0%p0
  %permissions%

where:
  %"0%D is current directory;
  and optional:
    %"0%p0
      for getting name and last modified date/time from file under cursor
      (if not exists or empty then will use name "New" and current date/time);
    %permissions%
      for Linux only, use octal mode (for example, 755 or 777).
