Introduction

A simple .NET Core library to manage Apache Shiro-styled permissions.

Inspired by the shiro-trie npm package and Apache Shiro styled permissions.

Installation

$ dotnet add package ShiroTrie

Example

var permissions = new[]
{
   "file:read",
   "file:write",
   "directory:delete,create",
   "image:png,jpeg:read,write",
   "audio:mp3,ogg:high,low:sample",
   "user:*",
   "mail",
   "tty"
};

// add permissions to trie
var trie = new PermissionTrie();
trie.Add(scopes);


// test permissions
var checks = new[]
{
   "file:read",
   "file:create",
   "file:update",
   "file:delete",
   "printer",
   "scanner:read",
   "image:png:read",
   "audio:mp3:high:sample",
   "audio:mp3:high:sample:once",
   "user:delete",
   "user:*",
   "user:create",
   "mail",
   "mail:delete",
   "mail:delete:once",
   "bash-tty",
};

foreach (var check in checks)
{
   Console.WriteLine("{0} = {1}", check, trie.Check(check));
}


/*
