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.
