This is the library for modern C++ projects presented by Usagi Ito[email protected] since 2015.

The library is under developing for ever, maybe. It will be integrate that have been implemented in the old libraries by the author.

• Include useful helper free functions and types.
• Subdivide a feature unit.
• Documentation by the Doxygen.
• Support header only usage as much as possible.

• to_string_iso8601_gmt: convert from a time_point to a ISO8601-string in GMT
• to_string_iso8601_jst: convert from a time_point to a ISO8601-string in JST
• from_iso8601: convert from a ISO8601-string to a time_point
• time_zone_difference: get a time zone difference

• circular_tile: a container type as a 2d-circular buffer

• circular_modulus: modulus for get an unified sequence in all negative or positive values

• ARRAY_ELEMENTSOF: get a count of elements in an array type.
• ELEMENTSOF: get a count of elements in a type.
• OFFSETOF: get a memory address offset of element in a type.

Have an easy development for several strange environment if include it.
