There's now the nonstd-lite organisation account, where lite projects and issues may eventually migrate to.

Please note that the various lite projects are standalone projects, each a single-file header-only C++ library, without any dependencies other than the standard library.

Issues of collective interest to these projects are collected in the nonstd-lite / nonstd-lite project.

Projects:

• active-lite – Active objects for C++11 and later.
• any-lite – A C++17-like any, a type-safe container for single values of any type for C++98, C++11 and later.
• atomic-lite – A C++11 atomic operations library for C++98 and later (WIP).
• bit-lite – C++20 bit operations for C++98 and later.
• boolean-lite – A strong boolean type for C++98 and later.
• byte-lite – A C++17-like byte type for C++98, C++11 and later.
• expected-lite – C++23 expected objects for C++11 and later.
• indirect-value-lite – An indirect value-type for C++11 and later (p1950).
• invoke-lite – C++17-like invoke() for C++98, C++11 and later (WIP).
• jthread-lite – C++20's jthread for C++11 and later (WIP).
• observer-ptr-lite – An observer_ptr for C++98 and later (Extensions for Library Fundamentals, v2, v3).
• optional-fun-lite – Functional algorithms for optional (lite) for C++98, C++11 and later.
  See also optional-lite.
• optional-bare – A simple version of a C++17-like optional for default-constructible, copyable types, for C++98 and later.
• optional-lite – A C++17-like optional, a nullable object for C++98, C++11 and later.
• ring-span-lite – A ring_span type for C++98, C++11 and later (p0059).
• scope-lite – C++ library extensions scope_exit, scope_fail, scope_success, unique_resource (C++ standard libraries extensions, version 3: Generic scope and RAII Wrapper.).
• span-lite – A C++20-like span for C++98, C++11 and later.
• status-value-lite – A class for status and optional value for C++11 and later, with C++98 variant also provided (p0262).
• string-lite – String algorithms for C++11 and later.
• string-non-lite – String facilities for C++98 and later.
  Prefer to use string-lite.
• string-view-lite – A C++17-like string_view for C++98, C++11 and later .
• type-lite – Strong types for C++98, C++11 and later.
• value-ptr-lite – A C++ smart-pointer with value semantics for C++98, C++11 and later.
  See also indirect-value-lite.
• variant-lite – A C++17-like variant, a type-safe union for C++98, C++11 and later.
