Description:

toml11 is a C++11 (or later) header-only toml parser/encoder depending only on
C++ standard library.

* It is compatible to the latest version of TOML v1.0.0.
* It is one of the most TOML standard compliant libraries, tested with the
language agnostic test suite for TOML parsers by BurntSushi.
* It shows highly informative error messages. You can see the error messages
about invalid files at CircleCI.
* It has configurable container. You can use any random-access containers
and key-value maps as backend containers.
* It optionally preserves comments without any overhead.
* It has configurable serializer that supports comments, inline tables,
literal strings and multiline strings.
* It supports user-defined type conversion from/into toml values.
* It correctly handles UTF-8 sequences, with or without BOM, both on posix
and Windows.
