# 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

// 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
