# 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
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

# HLog - v0.10.3
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 {
log.Fatal(err)
}
defer logger.CloseLogFile()
// Start logging
logger.Info().Msg("Application started")
logger.Debug().Str("user", "john").Msg("User logged in")
logger.Error().Err(err).Msg("Something went wrong")
}
```

// 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

# HWS (H Web Server) - v0.2.2
A lightweight, opinionated HTTP web server framework for Go built on top of the standard library's net/http.
## Features
- Built on Go 1.22+ routing patterns with method and path matching
- Structured error handling with customizable error pages
- Integrated logging with zerolog via hlog
- Middleware support with predictable execution order
- GZIP compression support
- Safe static file serving (prevents directory listing)
- Environment variable configuration with ConfigFromEnv
- Request timing and logging middleware
- Graceful shutdown support
- Built-in health check endpoint
## Installation
```bash
go get git.haelnorr.com/h/golib/hws
```
## Quick Start
```go
package main
import (
"context"
"net/http"
"git.haelnorr.com/h/golib/hws"
)
func main() {
// Load configuration from environment variables
config, _ := hws.ConfigFromEnv()
// Create server
server, _ := hws.NewServer(config)
// Define routes
routes := []hws.Route{
{
Path: "/",
Method: hws.MethodGET,
Handler: http.HandlerFunc(homeHandler),
},
{
Path: "/api/users/{id}",
Method: hws.MethodGET,
Handler: http.HandlerFunc(getUserHandler),
},
}
// Add routes and middleware
server.AddRoutes(routes...)
server.AddMiddleware()
// Start server
ctx := context.Background()
server.Start(ctx)
// Wait for server to be ready
<-server.Ready()
}
func homeHandler(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("Hello, World!"))
}
func getUserHandler(w http.ResponseWriter, r *http.Request) {
id := r.PathValue("id")
w.Write([]byte("User ID: " + id))
}
```

// 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

// 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_LANDING_PAGE: Redirect destination for authenticated users (default: "/profile")
// - HWSAUTH_DATABASE_TYPE: Database type - postgres, mysql, sqlite, mariadb (default: "postgres")
// - HWSAUTH_DATABASE_VERSION: Database version string (default: "15")
// - 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 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.
