LUA MODULE

  globtopattern v$(_VERSION) - converts file glob string to Lua pattern string.

SYNOPSIS
  
  local globtopattern = require 'globtopattern'.globtopattern
  local pat = globtopattern '[a-z]??.htm*' --> ^[a-z]..%.htm.*$
  assert(('a01.html'):match(pat))

DESCRIPTION

  This module converts a file glob expression [1,2] into a Lua pattern, which
  can then be used in Lua's pattern matching function.
  File globs are a common means to match file names.  Roughly in concept,
  ignoring differences in syntax, globs are a subset of Lua patterns which
  are a subset of regular expressions. However, globs sometimes have some
  obscure rules and corner cases (see below) depending on chosen syntax. [3-4]

API  
 
  p = globtopattern(g)

    Converts glob string `g` into Lua pattern string `p`.
    Always succeeds.

  Warning: This might not completely conform to POSIX or other specifications.
  Further validation should be done on syntax implemented.

DEPENDENCIES

  None (other than Lua 5.1 or 5.2).

       Wildcards in Windows/MSDOS.
       Windows globs are often implemented by calling the FindFileFirst /
       FindFileNext Win32 API calls.  The glob function implemented by Windows
       FindFileFirst/FindFileNext API calls can be especially counterintuitive
       and should sometimes be avoided (e.g. *.txt may match both 1.txt and
       1.txt~). So, wrapping these API calls in a Lua extension DLL may not
       be the most desirable approach.
