toml++ is a header-only C++17 library for parsing and serializing TOML configuration files, with optional serialization to JSON and YAML. It passes the full toml-test suite, handles UTF-8 properly, and works with or without exceptions and RTTI.

Use cases

• parse toml config files in c++
• read configuration files in a c++17 project
• convert toml to json or yaml in c++
• write toml files from c++
• header-only toml parser with no dependencies
• parse toml from strings or streams

When to choose

• you need a spec-compliant TOML v1.0.0 parser for C++17 or later
• you want a dependency-free, header-only library you can drop into a project
• you need to serialize TOML data to JSON or YAML
• you need proper UTF-8 handling and support for compilers without RTTI or exceptions

When to avoid

• you need a runtime library rather than a compile-time header-only dependency
• your project targets C++ standards older than C++17
• you need a general-purpose configuration format beyond TOML/JSON/YAML
• you need incremental or streaming parsing of very large files
