+# GOLIB Rules
+
+1. All changes should be documented
+Documentation is done in a few ways:
+ - docstrings
+ - README.md
+ - doc.go
+ - wiki
+
+The README for each module should be laid out as follows:
+- Title and description with version number
+- Feature list (DO NOT USE EMOTICONS)
+- Installation (go get)
+- Quick Start (brief example of setting up and using)
+- Documentation links to the wiki (path is `../golib/wiki/<package>.md`)
+- Additional information (e.g. supported databases if package has database features)
+- License
+- Contributing
+- Related projects (if relevant)
+
+Docstrings and doc.go should conform to godoc standards.
+Any Config structs with environment variables should have their docstrings match the format
+`// ENV ENV_NAME: Description (required <optional condition>) (default: <default value>)`
+where the required and default fields are only present if relevant to that variable
+
+The wiki is located at ~/projects/golib-wiki and should be laid out as follows:
+- Link to wiki page from the Home page
+- Title and description with version number
+- Installation
+- Key Concepts and features
+- Quick start
+- Configuration (explicity prefer using ConfigFromEnv for packages that support it)
+- Detailed sections on how to use all the features
+- Integration (many of the packages in this repo are designed to work in tandem. any close integration with other packages should be mentioned here)
+- Best practices
+- Troubleshooting
+- See also (links to other related or imported packages from this repo)
+- Links (GoDoc api link, source code, issue tracker)
+
+2. All features should have tests.
+Any changes to existing features or additional features implemented should have tests created and/or updated
+
+3. Version control
+Do not make any changes to master. Checkout a branch to work on new features
+Version numbers are specified using git tags.
+Do not change version numbers. When updating documentation, append the branch name to the version number.
+Changes made to the golib-wiki repo should be made under the same branch name as the changes made in this repo

+
+## Installation
+
+```bash
+go get git.haelnorr.com/h/golib/ezconf
+```
+
+## Quick Start
+
+### Easy Integration (Recommended)
+
+```go
+package main
+
+import (
+	"log"
+	"os"
+
+	"git.haelnorr.com/h/golib/ezconf"
+	"git.haelnorr.com/h/golib/hlog"
+	"git.haelnorr.com/h/golib/hws"
+	"git.haelnorr.com/h/golib/hwsauth"
+)
+
+func main() {
+	// Create a new configuration loader
+	loader := ezconf.New()
+
+	// Register packages using built-in integrations
+	loader.RegisterIntegrations(
+		hlog.NewEZConfIntegration(),
+		hws.NewEZConfIntegration(),
+		hwsauth.NewEZConfIntegration(),
+	)
+
+	// Load all configurations
+	if err := loader.Load(); err != nil {
+		log.Fatal(err)
+	}
+
+	// Get configurations
+	hlogCfg, _ := loader.GetConfig("hlog")
+	cfg := hlogCfg.(*hlog.Config)
+
+	// Use configuration
+	logger, _ := hlog.NewLogger(cfg, os.Stdout)
+	logger.Info().Msg("Application started")
+}
+```
+
+### Manual Integration
+
+```go
+package main
+
+import (
+	"log"
+	"os"
+
+	"git.haelnorr.com/h/golib/ezconf"
+	"git.haelnorr.com/h/golib/hlog"
+	"git.haelnorr.com/h/golib/hws"
+)
+
+func main() {
+	// Create a new configuration loader
+	loader := ezconf.New()
+
+	// Add package paths to parse for ENV comments
+	loader.AddPackagePath("vendor/git.haelnorr.com/h/golib/hlog")
+	loader.AddPackagePath("vendor/git.haelnorr.com/h/golib/hws")
+
+	// Add configuration loaders
+	loader.AddConfigFunc("hlog", func() (interface{}, error) {
+		return hlog.ConfigFromEnv()
+	})
+	loader.AddConfigFunc("hws", func() (interface{}, error) {
+		return hws.ConfigFromEnv()
+	})
+
+	// Load all configurations
+	if err := loader.Load(); err != nil {
+		log.Fatal(err)
+	}
+
+	// Get a specific configuration
+	hlogCfg, ok := loader.GetConfig("hlog")
+	if ok {
+		cfg := hlogCfg.(*hlog.Config)
+		// Use configuration...
+	}
+
+	// Print all environment variables
+	if err := loader.PrintEnvVarsStdout(false); err != nil {
+		log.Fatal(err)
+	}
+
+	// Generate a .env file
+	if err := loader.GenerateEnvFile(".env", false); err != nil {
+		log.Fatal(err)
+	}
+}
+```
+
+## Documentation
+
+For detailed documentation, see the [EZConf Wiki](../golib-wiki/EZConf.md).
+
+Additional API documentation is available at [GoDoc](https://pkg.go.dev/git.haelnorr.com/h/golib/ezconf).
+
+## ENV Comment Format
+
+EZConf parses struct field comments in the following format:
+
+```go
+type Config struct {
+	// ENV LOG_LEVEL: Log level for the application (default: info)
+	LogLevel string
+
+	// ENV DATABASE_URL: Database connection string (required)
+	DatabaseURL string
+	
+	// Inline comments also work
+	Port int // ENV PORT: Server port (default: 8080)
+}
+```
+
+The format is:
+- `ENV ENV_VAR_NAME: Description (optional modifiers)`
+- `(required)` or `(required if condition)` - marks variable as required
+- `(default: value)` - specifies default value

+// Package ezconf provides a unified configuration management system for loading
+// and managing environment-based configurations across multiple packages.
+//
+// ezconf allows you to:
+//   - Load configurations from multiple packages using their ConfigFromEnv functions
+//   - Parse package source code to extract environment variable documentation
+//   - Generate and update .env files with all required environment variables
+//   - Print environment variable lists with descriptions and current values
+//   - Track additional custom environment variables
+//
+// # Basic Usage
+//
+// Create a configuration loader and register packages using built-in integrations (recommended):
+//
+//	import (
+//		"git.haelnorr.com/h/golib/ezconf"
+//		"git.haelnorr.com/h/golib/hlog"
+//		"git.haelnorr.com/h/golib/hws"
+//		"git.haelnorr.com/h/golib/hwsauth"
+//	)
+//
+//	loader := ezconf.New()
+//
+//	// Register packages using built-in integrations
+//	loader.RegisterIntegrations(
+//		hlog.NewEZConfIntegration(),
+//		hws.NewEZConfIntegration(),
+//		hwsauth.NewEZConfIntegration(),
+//	)
+//
+//	// Load all configurations
+//	if err := loader.Load(); err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	// Get a specific configuration
+//	hlogCfg, ok := loader.GetConfig("hlog")
+//	if ok {
+//		cfg := hlogCfg.(*hlog.Config)
+//		// Use configuration...
+//	}
+//
+// Alternatively, you can manually register packages:
+//
+//	loader := ezconf.New()
+//
+//	// Add package paths to parse for ENV comments
+//	loader.AddPackagePath("/path/to/golib/hlog")
+//
+//	// Add configuration loaders
+//	loader.AddConfigFunc("hlog", func() (interface{}, error) {
+//		return hlog.ConfigFromEnv()
+//	})
+//
+//	loader.Load()
+//
+// # Printing Environment Variables
+//
+// Print all environment variables with their descriptions:
+//
+//	// Print without values (useful for documentation)
+//	if err := loader.PrintEnvVarsStdout(false); err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	// Print with current values
+//	if err := loader.PrintEnvVarsStdout(true); err != nil {
+//		log.Fatal(err)
+//	}
+//
+// # Generating .env Files
+//
+// Generate a new .env file with all environment variables:
+//
+//	// Generate with default values
+//	err := loader.GenerateEnvFile(".env", false)
+//
+//	// Generate with current environment values
+//	err := loader.GenerateEnvFile(".env", true)
+//
+// Update an existing .env file:
+//
+//	// Update existing file, preserving existing values
+//	err := loader.UpdateEnvFile(".env", true)
+//
+// # Adding Custom Environment Variables
+//
+// You can add additional environment variables that aren't in package configs:
+//
+//	loader.AddEnvVar(ezconf.EnvVar{
+//		Name:        "DATABASE_URL",
+//		Description: "PostgreSQL connection string",
+//		Required:    true,
+//		Default:     "postgres://localhost/mydb",
+//	})
+//
+// # ENV Comment Format
+//
+// ezconf parses struct field comments in the following format:
+//
+//	type Config struct {
+//		// ENV LOG_LEVEL: Log level for the application (default: info)
+//		LogLevel string
+//
+//		// ENV DATABASE_URL: Database connection string (required)
+//		DatabaseURL string
+//	}
+//
+// The format is:
+//   - ENV ENV_VAR_NAME: Description (optional modifiers)
+//   - (required) or (required if condition) - marks variable as required
+//   - (default: value) - specifies default value
+//
+// # Integration
+//
+// ezconf integrates with:
+//   - All golib packages that follow the ConfigFromEnv pattern
+//   - Any custom configuration structs with ENV comments
+//   - Standard .env file format

+# HLog - v0.10.4
+
+A structured logging package for Go built on top of [zerolog](https://github.com/rs/zerolog). HLog provides simple configuration via environment variables, flexible output options, and automatic log file management.
+
+## Features

+- Multiple output modes: console, file, or both simultaneously
+- Configurable log levels: trace, debug, info, warn, error, fatal, panic
+- Environment variable-based configuration with ConfigFromEnv
+- Automatic log file management with append or overwrite modes
+- Built on zerolog for high performance and structured logging
+- Error stack trace support via pkg/errors integration
+- Unix timestamp format
+- Console-friendly output formatting
+- Multi-writer support for simultaneous console and file output
+
+## Installation
+
+```bash
+go get git.haelnorr.com/h/golib/hlog
+```
+
+## Quick Start
+
+```go
+package main

+import (
+	"log"
+	"os"
+
+	"git.haelnorr.com/h/golib/hlog"
+)
+
+func main() {
+	// Load configuration from environment variables
+	cfg, err := hlog.ConfigFromEnv()
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	// Create a new logger
+	logger, err := hlog.NewLogger(cfg, os.Stdout)
+	if err != nil {

+// Package hlog provides a structured logging solution built on top of zerolog.
+//
+// hlog supports multiple output modes (console, file, or both), configurable
+// log levels, and automatic log file management. It is designed to be simple
+// to configure via environment variables while remaining flexible for
+// programmatic configuration.
+//
+// # Basic Usage
+//
+// Create a logger with environment-based configuration:
+//
+//	cfg, err := hlog.ConfigFromEnv()
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	logger, err := hlog.NewLogger(cfg, os.Stdout)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//	defer logger.CloseLogFile()
+//
+//	logger.Info().Msg("Application started")
+//
+// # Configuration
+//
+// hlog can be configured via environment variables using ConfigFromEnv:
+//
+//	LOG_LEVEL=info             # trace, debug, info, warn, error, fatal, panic (default: info)
+//	LOG_OUTPUT=console         # console, file, or both (default: console)
+//	LOG_DIR=/var/log/app       # Required when LOG_OUTPUT is "file" or "both"
+//	LOG_FILE_NAME=server.log   # Required when LOG_OUTPUT is "file" or "both"
+//	LOG_APPEND=true            # Append to existing file or overwrite (default: true)
+//
+// Or programmatically:
+//
+//	cfg := &hlog.Config{
+//		LogLevel:    hlog.InfoLevel,
+//		LogOutput:   "both",
+//		LogDir:      "/var/log/myapp",
+//		LogFileName: "server.log",
+//		LogAppend:   true,
+//	}
+//
+// # Log Levels
+//
+// hlog supports the following log levels (from most to least verbose):
+//   - trace: Very detailed debugging information
+//   - debug: Detailed debugging information
+//   - info: General informational messages
+//   - warn: Warning messages for potentially harmful situations
+//   - error: Error messages for error events
+//   - fatal: Fatal messages that will exit the application
+//   - panic: Panic messages that will panic the application
+//
+// # Output Modes
+//
+//   - console: Logs to the provided io.Writer (typically os.Stdout or os.Stderr)
+//   - file: Logs to a file in the configured directory
+//   - both: Logs to both console and file simultaneously using zerolog.MultiLevelWriter
+//
+// # File Management
+//
+// When using file output, hlog creates a file with the specified name in the
+// configured directory. The file can be opened in append mode (default) to
+// preserve logs across application restarts, or in overwrite mode to start
+// fresh each time. Remember to call CloseLogFile() when shutting down your
+// application to ensure all logs are flushed to disk.
+//
+// # Error Stack Traces
+//
+// hlog automatically configures zerolog to include stack traces for errors
+// wrapped with github.com/pkg/errors. This provides detailed error context
+// when using errors.Wrap or errors.WithStack.
+//
+// # Integration
+//
+// hlog integrates with:
+//   - git.haelnorr.com/h/golib/env: For environment variable configuration
+//   - github.com/rs/zerolog: The underlying logging implementation
+//   - github.com/pkg/errors: For error stack trace support

+// Package hws provides a lightweight HTTP web server framework built on top of Go's standard library.
+//
+// HWS (H Web Server) is an opinionated framework that leverages Go 1.22+ routing patterns
+// with built-in middleware, structured error handling, and production-ready defaults. It
+// integrates seamlessly with other golib packages like hlog for logging and hwsauth for
+// authentication.
+//
+// # Basic Usage
+//
+// Create a server with environment-based configuration:
+//
+//	cfg, err := hws.ConfigFromEnv()
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	server, err := hws.NewServer(cfg)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	routes := []hws.Route{
+//		{
+//			Path:    "/",
+//			Method:  hws.MethodGET,
+//			Handler: http.HandlerFunc(homeHandler),
+//		},
+//	}
+//
+//	server.AddRoutes(routes...)
+//	server.AddMiddleware()
+//
+//	ctx := context.Background()
+//	server.Start(ctx)
+//
+//	<-server.Ready()
+//
+// # Configuration
+//
+// HWS can be configured via environment variables using ConfigFromEnv:
+//
+//	HWS_HOST=127.0.0.1                # Host to listen on (default: 127.0.0.1)
+//	HWS_PORT=3000                     # Port to listen on (default: 3000)
+//	HWS_GZIP=false                    # Enable GZIP compression (default: false)
+//	HWS_READ_HEADER_TIMEOUT=2         # Header read timeout in seconds (default: 2)
+//	HWS_WRITE_TIMEOUT=10              # Write timeout in seconds (default: 10)
+//	HWS_IDLE_TIMEOUT=120              # Idle connection timeout in seconds (default: 120)
+//
+// Or programmatically:
+//
+//	cfg := &hws.Config{
+//		Host:              "0.0.0.0",
+//		Port:              8080,
+//		GZIP:              true,
+//		ReadHeaderTimeout: 5 * time.Second,
+//		WriteTimeout:      15 * time.Second,
+//		IdleTimeout:       120 * time.Second,
+//	}
+//
+// # Routing
+//
+// HWS uses Go 1.22+ routing patterns with method-specific handlers:
+//
+//	routes := []hws.Route{
+//		{
+//			Path:    "/users/{id}",
+//			Method:  hws.MethodGET,
+//			Handler: http.HandlerFunc(getUser),
+//		},
+//		{
+//			Path:    "/users/{id}",
+//			Method:  hws.MethodPUT,
+//			Handler: http.HandlerFunc(updateUser),
+//		},
+//	}
+//
+// Path parameters can be accessed using r.PathValue():
+//
+//	func getUser(w http.ResponseWriter, r *http.Request) {
+//		id := r.PathValue("id")
+//		// ... handle request
+//	}
+//
+// # Middleware
+//
+// HWS supports middleware with predictable execution order. Built-in middleware includes
+// request logging, timing, and GZIP compression:
+//
+//	server.AddMiddleware()
+//
+// Custom middleware can be added using standard http.Handler wrapping:
+//
+//	server.AddMiddleware(customMiddleware)
+//
+// # Error Handling
+//
+// HWS provides structured error handling with customizable error pages:
+//
+//	errorPageFunc := func(w http.ResponseWriter, r *http.Request, status int) {
+//		w.WriteHeader(status)
+//		fmt.Fprintf(w, "Error: %d", status)
+//	}
+//
+//	server.AddErrorPage(errorPageFunc)
+//
+// # Logging
+//
+// HWS integrates with hlog for structured logging:
+//
+//	logger, _ := hlog.NewLogger(loggerCfg, os.Stdout)
+//	server.AddLogger(logger)
+//
+// The server will automatically log requests, errors, and server lifecycle events.
+//
+// # Static Files
+//
+// HWS provides safe static file serving that prevents directory listing:
+//
+//	server.AddStaticFiles("/static", "./public")
+//
+// # Graceful Shutdown
+//
+// HWS supports graceful shutdown via context cancellation:
+//
+//	ctx, cancel := context.WithCancel(context.Background())
+//	defer cancel()
+//
+//	server.Start(ctx)
+//
+//	// Wait for shutdown signal
+//	sigChan := make(chan os.Signal, 1)
+//	signal.Notify(sigChan, os.Interrupt, syscall.SIGTERM)
+//	<-sigChan
+//
+//	// Cancel context to trigger graceful shutdown
+//	cancel()
+//
+// # Integration
+//
+// HWS integrates with:
+//   - git.haelnorr.com/h/golib/hlog: For structured logging with zerolog
+//   - git.haelnorr.com/h/golib/hwsauth: For JWT-based authentication
+//   - git.haelnorr.com/h/golib/jwt: For JWT token management

+# HWSAuth - v0.3.4
+
+JWT-based authentication middleware for the HWS web framework.
+
+## Features
+
+- JWT-based authentication with access and refresh tokens
+- Automatic token rotation and refresh
+- Generic over user model and transaction types
+- ORM-agnostic transaction handling (works with GORM, Bun, sqlx, database/sql)
+- Environment variable configuration with ConfigFromEnv
+- Middleware for protecting routes
+- SSL cookie security support
+- Type-safe with Go generics
+- Path ignoring for public routes
+- Automatic re-authentication handling
+
+## Installation
+
+```bash
+go get git.haelnorr.com/h/golib/hwsauth

+// Package hwsauth provides JWT-based authentication middleware for the hws web framework.
+//
+// # Overview
+//
+// hwsauth integrates with the hws web server to provide secure, stateless authentication
+// using JSON Web Tokens (JWT). It supports both access and refresh tokens, automatic
+// token rotation, and flexible transaction handling compatible with any database or ORM.
+//
+// # Key Features
+//
+//   - JWT-based authentication with access and refresh tokens
+//   - Automatic token rotation and refresh
+//   - Generic over user model and transaction types
+//   - ORM-agnostic transaction handling
+//   - Environment variable configuration
+//   - Middleware for protecting routes
+//   - Context-based user retrieval
+//   - Optional SSL cookie security
+//
+// # Quick Start
+//
+// First, define your user model:
+//
+//	type User struct {
+//	    UserID   int
+//	    Username string
+//	    Email    string
+//	}
+//
+//	func (u User) ID() int {
+//	    return u.UserID
+//	}
+//
+// Configure the authenticator using environment variables or programmatically:
+//
+//	// Option 1: Load from environment variables
+//	cfg, err := hwsauth.ConfigFromEnv()
+//	if err != nil {
+//	    log.Fatal(err)
+//	}
+//
+//	// Option 2: Create config manually
+//	cfg := &hwsauth.Config{
+//	    SSL:                true,
+//	    TrustedHost:        "https://example.com",
+//	    SecretKey:          "your-secret-key",
+//	    AccessTokenExpiry:  5,     // 5 minutes
+//	    RefreshTokenExpiry: 1440,  // 1 day
+//	    TokenFreshTime:     5,     // 5 minutes
+//	    LandingPage:        "/dashboard",
+//	}
+//
+// Create the authenticator:
+//
+//	// Define how to begin transactions
+//	beginTx := func(ctx context.Context) (hwsauth.DBTransaction, error) {
+//	    return db.BeginTx(ctx, nil)
+//	}
+//
+//	// Define how to load users from the database
+//	loadUser := func(ctx context.Context, tx *sql.Tx, id int) (User, error) {
+//	    var user User
+//	    err := tx.QueryRowContext(ctx, "SELECT id, username, email FROM users WHERE id = ?", id).
+//	        Scan(&user.UserID, &user.Username, &user.Email)
+//	    return user, err
+//	}
+//
+//	// Create the authenticator
+//	auth, err := hwsauth.NewAuthenticator[User, *sql.Tx](
+//	    cfg,
+//	    loadUser,
+//	    server,
+//	    beginTx,
+//	    logger,
+//	    errorPage,
+//	)
+//	if err != nil {
+//	    log.Fatal(err)
+//	}
+//
+// # Middleware
+//
+// Use the Authenticate middleware to protect routes:
+//
+//	// Apply to all routes
+//	server.AddMiddleware(auth.Authenticate())
+//
+//	// Ignore specific paths
+//	auth.IgnorePaths("/login", "/register", "/public")
+//
+// Use route guards for specific protection requirements:
+//
+//	// LoginReq: Requires user to be authenticated
+//	protectedHandler := auth.LoginReq(myHandler)
+//
+//	// LogoutReq: Redirects authenticated users (for login/register pages)
+//	loginHandler := auth.LogoutReq(loginPageHandler)
+//
+//	// FreshReq: Requires fresh authentication (for sensitive operations)
+//	changePasswordHandler := auth.FreshReq(changePasswordHandler)
+//
+// # Login and Logout
+//
+// To log a user in:
+//
+//	func loginHandler(w http.ResponseWriter, r *http.Request) {
+//	    // Validate credentials...
+//	    user := getUserFromDatabase(username)
+//
+//	    // Log the user in (sets JWT cookies)
+//	    err := auth.Login(w, r, user, rememberMe)
+//	    if err != nil {
+//	        // Handle error
+//	    }
+//
+//	    http.Redirect(w, r, "/dashboard", http.StatusSeeOther)
+//	}
+//
+// To log a user out:
+//
+//	func logoutHandler(w http.ResponseWriter, r *http.Request) {
+//	    tx, _ := db.BeginTx(r.Context(), nil)
+//	    defer tx.Rollback()
+//
+//	    err := auth.Logout(tx, w, r)
+//	    if err != nil {
+//	        // Handle error
+//	    }
+//
+//	    tx.Commit()
+//	    http.Redirect(w, r, "/", http.StatusSeeOther)
+//	}
+//
+// # Retrieving the Current User
+//
+// Access the authenticated user from the request context:
+//
+//	func dashboardHandler(w http.ResponseWriter, r *http.Request) {
+//	    user := auth.CurrentModel(r.Context())
+//	    if user.ID() == 0 {
+//	        // User not authenticated
+//	        return
+//	    }
+//
+//	    fmt.Fprintf(w, "Welcome, %s!", user.Username)
+//	}
+//
+// # ORM Support
+//
+// hwsauth works with any ORM that implements the DBTransaction interface.
+//
+// GORM Example:
+//
+//	beginTx := func(ctx context.Context) (hwsauth.DBTransaction, error) {
+//	    return gormDB.WithContext(ctx).Begin().Statement.ConnPool.(*sql.Tx), nil
+//	}
+//
+//	loadUser := func(ctx context.Context, tx *gorm.DB, id int) (User, error) {
+//	    var user User
+//	    err := tx.First(&user, id).Error
+//	    return user, err
+//	}
+//
+//	auth, err := hwsauth.NewAuthenticator[User, *gorm.DB](...)
+//
+// Bun Example:
+//
+//	beginTx := func(ctx context.Context) (hwsauth.DBTransaction, error) {
+//	    return bunDB.BeginTx(ctx, nil)
+//	}
+//
+//	loadUser := func(ctx context.Context, tx bun.Tx, id int) (User, error) {
+//	    var user User
+//	    err := tx.NewSelect().Model(&user).Where("id = ?", id).Scan(ctx)
+//	    return user, err
+//	}
+//
+//	auth, err := hwsauth.NewAuthenticator[User, bun.Tx](...)
+//
+// # Environment Variables
+//
+// The following environment variables are supported when using ConfigFromEnv:
+//
+//   - HWSAUTH_SSL: Enable SSL secure cookies (default: false)
+//   - HWSAUTH_TRUSTED_HOST: Full server address for SSL (required if SSL is true)
+//   - HWSAUTH_SECRET_KEY: Secret key for signing JWT tokens (required)
+//   - HWSAUTH_ACCESS_TOKEN_EXPIRY: Access token expiry in minutes (default: 5)
+//   - HWSAUTH_REFRESH_TOKEN_EXPIRY: Refresh token expiry in minutes (default: 1440)
+//   - HWSAUTH_TOKEN_FRESH_TIME: Token fresh time in minutes (default: 5)

+//   - HWSAUTH_JWT_TABLE_NAME: Custom JWT blacklist table name (default: "jwtblacklist")
+//
+// # Security Considerations
+//
+//   - Always use SSL in production (set HWSAUTH_SSL=true)
+//   - Use strong, randomly generated secret keys
+//   - Set appropriate token expiry times based on your security requirements
+//   - Use FreshReq middleware for sensitive operations (password changes, etc.)
+//   - Store refresh tokens securely in HTTP-only cookies
+//
+// # Type Parameters
+//
+// hwsauth uses Go generics for type safety:
+//
+//   - T Model: Your user model type (must implement the Model interface)
+//   - TX DBTransaction: Your transaction type (must implement DBTransaction interface)
+//
+// This allows compile-time type checking and eliminates the need for type assertions
+// when working with your user models.

+// Package jwt provides JWT (JSON Web Token) generation and validation with token revocation support.
+//
+// This package implements JWT access and refresh tokens with the ability to revoke tokens
+// using a database-backed blacklist. It supports multiple database backends including
+// PostgreSQL, MySQL, SQLite, and MariaDB, and works with both standard library database/sql
+// and popular ORMs like GORM and Bun.
+//
+// # Features
+//
+//   - Access and refresh token generation
+//   - Token validation with expiration checking
+//   - Token revocation via database blacklist
+//   - Support for multiple database types (PostgreSQL, MySQL, SQLite, MariaDB)
+//   - Compatible with database/sql, GORM, and Bun ORMs
+//   - Automatic table creation and management
+//   - Database-native automatic cleanup (PostgreSQL functions, MySQL events)
+//   - Manual cleanup method for on-demand token cleanup
+//   - Token freshness tracking for sensitive operations
+//   - "Remember me" functionality with session vs persistent tokens
+//
+// # Basic Usage
+//
+// Create a token generator with database support:
+//
+//	db, _ := sql.Open("postgres", "connection_string")
+//	gen, err := jwt.CreateGenerator(jwt.GeneratorConfig{
+//	    AccessExpireAfter:  15,   // 15 minutes
+//	    RefreshExpireAfter: 1440, // 24 hours
+//	    FreshExpireAfter:   5,    // 5 minutes
+//	    TrustedHost:        "example.com",
+//	    SecretKey:          "your-secret-key",
+//	    DB:                 db,
+//	    DBType:             jwt.DatabaseType{Type: jwt.DatabasePostgreSQL, Version: "15"},
+//	    TableConfig:        jwt.DefaultTableConfig(),
+//	})
+//
+// Generate tokens:
+//
+//	accessToken, accessExp, err := gen.NewAccess(userID, true, false)
+//	refreshToken, refreshExp, err := gen.NewRefresh(userID, false)
+//
+// Validate tokens (using standard library):
+//
+//	tx, _ := db.Begin()
+//	token, err := gen.ValidateAccess(tx, accessToken)
+//	if err != nil {
+//	    // Token is invalid or revoked
+//	}
+//	tx.Commit()
+//
+// Validate tokens (using ORM like GORM):
+//
+//	tx := gormDB.Begin()
+//	token, err := gen.ValidateAccess(tx.Statement.ConnPool, accessToken)
+//	// or with Bun: gen.ValidateAccess(bunDB.BeginTx(ctx, nil), accessToken)
+//	tx.Commit()
+//
+// Revoke tokens:
+//
+//	tx, _ := db.Begin()
+//	err := token.Revoke(tx)
+//	tx.Commit()
+//
+// # Database Configuration
+//
+// The package automatically creates a blacklist table with the following schema:
+//
+//	CREATE TABLE jwtblacklist (
+//	    jti UUID PRIMARY KEY,      -- Token unique identifier
+//	    exp BIGINT NOT NULL,        -- Expiration timestamp
+//	    sub INT NOT NULL,           -- Subject (user) ID
+//	    created_at TIMESTAMP        -- When token was blacklisted
+//	);
+//
+// # Cleanup
+//
+// For PostgreSQL, the package creates a cleanup function that can be called manually
+// or scheduled with pg_cron:
+//
+//	SELECT cleanup_jwtblacklist();
+//
+// For MySQL/MariaDB, the package creates a database event that runs automatically
+// (requires event_scheduler to be enabled).
+//
+// Manual cleanup can be performed at any time:
+//
+//	err := gen.Cleanup(context.Background())
+//
+// # Using with ORMs
+//
+// The package works with popular ORMs by using raw SQL queries. For GORM and Bun,
+// wrap the underlying *sql.DB with NewDBConnection() when creating the generator:
+//
+//	// GORM example - can use GORM transactions directly
+//	gormDB, _ := gorm.Open(postgres.Open(dsn), &gorm.Config{})
+//	sqlDB, _ := gormDB.DB()
+//	gen, _ := jwt.CreateGenerator(jwt.GeneratorConfig{
+//	    // ... config ...
+//	    DB: sqlDB,
+//	})
+//	// Use GORM transaction
+//	tx := gormDB.Begin()
+//	token, _ := gen.ValidateAccess(tx.Statement.ConnPool, tokenString)
+//	tx.Commit()
+//
+//	// Bun example - can use Bun transactions directly
+//	sqlDB, _ := sql.Open("postgres", dsn)
+//	bunDB := bun.NewDB(sqlDB, pgdialect.New())
+//	gen, _ := jwt.CreateGenerator(jwt.GeneratorConfig{
+//	    // ... config ...
+//	    DB: sqlDB,
+//	})
+//	// Use Bun transaction
+//	tx, _ := bunDB.BeginTx(context.Background(), nil)
+//	token, _ := gen.ValidateAccess(tx, tokenString)
+//	tx.Commit()
+//
+// # Token Freshness
+//
+// Tokens can be marked as "fresh" for sensitive operations. Fresh tokens are typically
+// required for actions like changing passwords or email addresses:
+//
+//	token, err := gen.ValidateAccess(exec, tokenString)
+//	if time.Now().Unix() > token.Fresh {
+//	    // Token is not fresh, require re-authentication
+//	}
+//
+// # Custom Table Names
+//
+// You can customize the blacklist table name:
+//
+//	config := jwt.DefaultTableConfig()
+//	config.TableName = "my_token_blacklist"
+//
+// # Disabling Database Features
+//
+// To use JWT without revocation support (no database):
+//
+//	gen, err := jwt.CreateGenerator(jwt.GeneratorConfig{
+//	    AccessExpireAfter:  15,
+//	    RefreshExpireAfter: 1440,
+//	    FreshExpireAfter:   5,
+//	    TrustedHost:        "example.com",
+//	    SecretKey:          "your-secret-key",
+//	    DB:                 nil, // No database
+//	})
+//
+// When DB is nil, revocation features are disabled and token validation
+// will not check the blacklist.

+fmt.Printf("IMDb ID: %s\n", movie.IMDbID)
+fmt.Printf("Rating: %.1f/10\n", movie.VoteAverage)
+```
+
+### Getting Cast and Crew
+
+```go
+// Get credits for a movie
+credits, err := api.GetCredits(550)
+if err != nil {
+    log.Fatal(err)
+}
+
+fmt.Println("Cast:")
+for _, actor := range credits.Cast {
+    fmt.Printf("  %s as %s\n", actor.Name, actor.Character)
+}
+
+fmt.Println("\nDirector:")
+for _, member := range credits.Crew {
+    if member.Job == "Director" {
+        fmt.Printf("  %s\n", member.Name)
+    }
+}
+```
+
+## Configuration
+
+### Environment Variables
+
+The package requires the following environment variable:
+
+```bash
+# TMDB API access token (required)
+TMDB_TOKEN=your_api_token_here
+```
+
+Get your API token from: https://www.themoviedb.org/settings/api
+
+### Using EZConf Integration
+
+```go
+import (
+    "git.haelnorr.com/h/golib/ezconf"
+    "git.haelnorr.com/h/golib/tmdb"
+)
+
+loader := ezconf.New()
+loader.RegisterIntegration(tmdb.NewEZConfIntegration())
+loader.Load()
+
+// Get the configured API connection
+api, ok := loader.GetConfig("tmdb")
+if !ok {
+    log.Fatal("tmdb config not found")
+}
+```
+
+## Rate Limiting
+
+TMDB has rate limits around 40 requests per second. This package implements automatic retry logic with exponential backoff:
+
+- **Initial backoff**: 1 second
+- **Exponential growth**: 1s → 2s → 4s → 8s → 16s → 32s (max)
+- **Maximum retries**: 3 attempts
+- **Respects** Retry-After header when provided by the API
+
+All API calls automatically handle rate limiting, so you don't need to worry about it.
+
+## Image URLs
+
+The TMDB API provides base URLs for images. Use helper methods to construct full image URLs:
+
+```go
+// Available poster sizes: "w92", "w154", "w185", "w342", "w500", "w780", "original"
+posterURL := movie.GetPoster(&api.Image, "w500")
+
+// Available backdrop sizes: "w300", "w780", "w1280", "original"
+backdropURL := movie.GetBackdrop(&api.Image, "w1280")
+
+// Available profile sizes: "w45", "w185", "h632", "original"
+profileURL := actor.GetProfile(&api.Image, "w185")
+```
+
+## API Reference
+
+### Main Functions
+
+- `NewAPIConnection() (*APIConnection, error)` - Create a new API connection
+- `SearchMovies(query string, includeAdult bool, page int) (*SearchResponse, error)` - Search for movies
+- `GetMovie(movieID int) (*Movie, error)` - Get detailed movie information
+- `GetCredits(movieID int) (*Credits, error)` - Get cast and crew information
+
+### Helper Methods
+
+**Movie Methods:**
+- `ReleaseYear() string` - Extract year from release date
+- `GetPoster(imgConfig *ImageConfig, size string) string` - Get full poster URL
+- `GetBackdrop(imgConfig *ImageConfig, size string) string` - Get full backdrop URL
+
+**Cast/Crew Methods:**
+- `GetProfile(imgConfig *ImageConfig, size string) string` - Get full profile image URL
+
+## Error Handling
+
+The package returns wrapped errors for easy debugging:
+
+```go
+data, err := api.SearchMovies("Inception", false, 1)
+if err != nil {
+    if strings.Contains(err.Error(), "rate limit exceeded") {
+        // Handle rate limiting
+    } else if strings.Contains(err.Error(), "unexpected status code: 401") {
+        // Invalid API token
+    } else if strings.Contains(err.Error(), "unexpected status code: 404") {
+        // Resource not found
+    } else {
+        // Network or other errors
+    }
+}
+```
+
+## Documentation
+
+For detailed documentation, see the [TMDB Wiki](https://git.haelnorr.com/h/golib/wiki/TMDB.md).
+
+Additional API documentation is available at [GoDoc](https://pkg.go.dev/git.haelnorr.com/h/golib/tmdb).
+
+## Testing
+
+Run the test suite (requires a valid TMDB_TOKEN environment variable):
+
+```bash
+export TMDB_TOKEN=your_api_token_here
+go test -v ./...
+```
+
+Current test coverage: 94.1%
+
+## Best Practices
+
+1. **Reuse API connections** - Create one connection and reuse it for multiple requests
+2. **Cache responses** - Cache API responses when appropriate to reduce API calls
+3. **Use specific image sizes** - Use appropriate image sizes instead of "original" to save bandwidth
+4. **Handle rate limits gracefully** - The library handles this automatically, but be aware it may introduce delays
+5. **Set a timeout** - Consider using context with timeout for long-running operations

+// Package tmdb provides a client for The Movie Database (TMDB) API.
+//
+// This package offers a clean interface for interacting with TMDB's REST API,
+// including automatic rate limiting, retry logic, and convenient URL building utilities.
+//
+// # Getting Started
+//
+// First, create an API connection using your TMDB API token:
+//
+//	api, err := tmdb.NewAPIConnection()
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+// The token is read from the TMDB_TOKEN environment variable.
+//
+// # Making Requests
+//
+// The package provides clean URL building functions to construct API requests:
+//
+//	// Simple endpoint
+//	url := tmdb.requestURL("movie", "550")
+//	// Result: "https://api.themoviedb.org/3/movie/550"
+//
+//	// With query parameters
+//	url := tmdb.buildURL([]string{"search", "movie"}, map[string]string{
+//		"query": "Inception",
+//		"page":  "1",
+//	})
+//	// Result: "https://api.themoviedb.org/3/search/movie?language=en-US&page=1&query=Inception"
+//
+// All requests made with buildURL automatically include "language=en-US" by default.
+//
+// # Rate Limiting
+//
+// TMDB has rate limits around 40 requests per second. This package implements
+// automatic retry logic with exponential backoff:
+//
+//   - Initial backoff: 1 second
+//   - Exponential growth: 1s → 2s → 4s → 8s → 16s → 32s (max)
+//   - Maximum retries: 3 attempts
+//   - Respects Retry-After header when provided by the API
+//
+// Example of rate-limited request:
+//
+//	data, err := api.get(url)
+//	if err != nil {
+//		// Will return error only after exhausting all retries
+//		log.Printf("Request failed: %v", err)
+//	}
+//
+// # Searching for Movies
+//
+// Search for movies by title:
+//
+//	results, err := tmdb.SearchMovies(token, "Fight Club", false, 1)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	for _, movie := range results.Results {
+//		fmt.Printf("%s %s\n", movie.Title, movie.ReleaseYear())
+//		fmt.Printf("Poster: %s\n", movie.GetPoster(&api.Image, "w500"))
+//	}
+//
+// # Getting Movie Details
+//
+// Fetch detailed information about a specific movie:
+//
+//	movie, err := tmdb.GetMovie(550, token)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	fmt.Printf("Title: %s\n", movie.Title)
+//	fmt.Printf("Overview: %s\n", movie.Overview)
+//	fmt.Printf("Release Date: %s\n", movie.ReleaseDate)
+//	fmt.Printf("IMDb ID: %s\n", movie.IMDbID)
+//
+// # Getting Credits
+//
+// Retrieve cast and crew information:
+//
+//	credits, err := tmdb.GetCredits(550, token)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	fmt.Println("Cast:")
+//	for _, actor := range credits.Cast {
+//		fmt.Printf("  %s as %s\n", actor.Name, actor.Character)
+//	}
+//
+//	fmt.Println("\nCrew:")
+//	for _, member := range credits.Crew {
+//		if member.Job == "Director" {
+//			fmt.Printf("  Director: %s\n", member.Name)
+//		}
+//	}
+//
+// # Image URLs
+//
+// The API configuration includes base URLs for images. Use helper methods to
+// construct full image URLs:
+//
+//	posterURL := movie.GetPoster(&api.Image, "w500")
+//	// Available sizes: "w92", "w154", "w185", "w342", "w500", "w780", "original"
+//
+// # Error Handling
+//
+// The package returns wrapped errors for easy debugging:
+//
+//	data, err := api.get(url)
+//	if err != nil {
+//		if strings.Contains(err.Error(), "rate limit exceeded") {
+//			// Handle rate limiting
+//		} else if strings.Contains(err.Error(), "unexpected status code") {
+//			// Handle HTTP errors
+//		} else {
+//			// Handle network errors
+//		}
+//	}
+//
+// Common error scenarios:
+//   - "rate limit exceeded: maximum retries reached" - All retry attempts exhausted
+//   - "unexpected status code: 401" - Invalid API token
+//   - "unexpected status code: 404" - Resource not found
+//   - Network errors for connectivity issues
+//
+// # Environment Variables
+//
+// The package uses the following environment variable:
+//
+//   - TMDB_TOKEN: Your TMDB API access token (required)
+//
+// Obtain an API token from: https://www.themoviedb.org/settings/api
+//
+// # Best Practices
+//
+// 1. Reuse the API connection instead of creating new ones for each request
+// 2. Use buildURL for consistency and automatic language parameter injection
+// 3. Handle rate limit errors gracefully - they indicate temporary service issues
+// 4. Cache API responses when appropriate to reduce API calls
+// 5. Use specific image sizes instead of "original" to save bandwidth
+//
+// # API Documentation
+//
+// For complete TMDB API documentation, visit:
+// https://developer.themoviedb.org/docs
+//
+// # Rate Limiting Details
+//
+// From TMDB's documentation:
+// "While our legacy rate limits have been disabled for some time, we do still
+// have some upper limits to help mitigate needlessly high bulk scraping. They
+// sit somewhere in the 40 requests per second range."
+//
+// This package automatically handles rate limiting with exponential backoff to
+// ensure respectful API usage.
