Glob for Garry's mod

Match files using the patterns the shell uses, like stars and stuff.

Inspiration comes from: https://github.com/isaacs/node-glob

Usage

The following characters have special magic meaning when used in a path portion:

• * Matches 0 or more characters in a single path portion
• ? Matches 1 character
• [...] Matches a range of characters, similar to a RegExp range. If the first character of the range is ! or ^ then it matches any character not in the range.
• ** If a "globstar" is alone in a path portion, then it matches zero or more directories and subdirectories searching for matches.

The following may be added at a later date:

• !(pattern|pattern|pattern) Matches anything that does not match any of the patterns provided.
• ?(pattern|pattern|pattern) Matches zero or one occurrence of the patterns provided.
• +(pattern|pattern|pattern) Matches one or more occurrences of the patterns provided.
• *(a|b|c) Matches zero or more occurrences of the patterns provided
• @(pattern|pat*|pat?erN) Matches exactly one of the patterns provided

Examples

Example 1

Find all configuration files.

File structure:

addons/lua/my-addon
.
├── config
│   ├── module1
│   │   ├── something.lua
│   │   ├── else.lua
│   ├── module2
│   │   ├── something.lua
│   │   ├── sub
│   │   │   ├── else.lua

How you would use the glob functionality:

local result = Glob.glob('LUA', '**/*.lua', 'my-addon/config', 'file')

result:

{
    'module1/something.lua',
    'module1/else.lua',
    'module2/something.lua',
    'module2/sub/else.lua',
}
