## What it is
goutil is a Go utility library providing 900+ helper functions across packages for strings, arrays, maps, structs, reflection, errors, time, filesystem, environment, CLI, and testing. It includes extras like a value dumper, enhanced error wrapping with stacktraces, assertion helpers, and a flag wrapper for building simple CLI apps.

## Use cases
- manipulate and convert strings in go
- convert between int, string, and byte types
- merge and query nested maps
- dump go variables for debugging
- wrap errors with stack traces
- build simple command line apps with flags
- read and write files quickly
- mock env values in tests

## When to choose
- you want a batteries-included stdlib-style utility set for Go
- you need many small helpers (strings, slices, maps, fs, env) from one dependency
- you want enhanced error wrapping, dumping, or test assertions

## When to avoid
- you prefer minimal, single-purpose dependencies
- you need a framework for complex CLI apps rather than simple flag handling
- your project avoids reflection-heavy utility libraries

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, serialization, logging, testing, cli, error-handling, file-system, date-time, math
- domain: developer-tools
- platform: go, cross-platform, cli
- tags: go-library, utilities, string-utils, slice-utils, map-utils, struct-utils, reflection, env-vars, dump, assert, cli-flags, ansi-colors, command-line, automation
