## What it is
toml11 is a feature-rich, header-only TOML parsing and serialization library for C++11/14/17/20. It fully complies with the TOML v1.0.0 specification, provides clear error messages with locations, preserves comments and formatting information, and supports type conversions to STL containers.

## Use cases
- parse TOML configuration files in C++
- serialize C++ data structures to TOML
- read config files with comments preserved
- convert TOML values into STL containers
- get clear error messages with line locations when parsing TOML
- support TOML 1.1 features in a C++ project

## When to choose
- you need a spec-compliant TOML parser for modern C++
- you want a header-only library with no dependencies
- you need to preserve comments and formatting when round-tripping TOML files
- you want detailed, location-aware parse error messages

## When to avoid
- your project uses a language other than C++
- you need a general-purpose configuration format like YAML or JSON instead of TOML
- you need runtime-driven dynamic schemas beyond TOML's type system

## Facets
- artifact type: library
- maturity: stable
- function: parser, serialization
- domain: developer-tools, files
- platform: cpp, cross-platform
- tags: toml, header-only, c-plus-plus, config-files
