Third-party components

calog vendors the following scripting engines under vendor/, built from source. Each is distributed under its own license (MIT unless noted), which applies to its files; the full text ships alongside each engine's source.

  • Lua 5.4 — Copyright (C) 1994-2023 Lua.org, PUC-Rio. MIT License. vendor/lua/ (see vendor/lua/README and the notice in src/lua.h).

  • QuickJS-ng (JavaScript) — Copyright (c) 2017-2024 Fabrice Bellard, Charlie Gordon, and QuickJS-ng contributors. MIT License. vendor/quickjs/quickjs.h.

  • Squirrel 3.2 — Copyright (c) 2003-2022 Alberto Demichelis. MIT License. vendor/squirrel-src/COPYRIGHT.

  • MY-BASIC — Copyright (C) 2011-2026 Tony Wang. MIT License. Notice in vendor/mybasic/myBasic.h.

    Note: vendor/mybasic/myBasic.c carries one small calog patch (making the global allocation counter _Atomic so interpreters are thread-safe); the unmodified original is preserved as vendor/mybasic/myBasic.c.orig.

  • s7 Scheme — Copyright (c) Bill Schottstaedt and s7 contributors. BSD-style license (TinyScheme lineage: use for any purpose, no royalty). Notice in vendor/s7/s7.c.

  • Wren — Copyright (c) 2013-2021 Robert Nystrom and Wren Contributors. MIT License. vendor/wren/LICENSE (amalgamated into vendor/wren/wren.c).

    Note: vendor/wren/wren.c and wren.h carry one small calog patch adding a public C map-key iterator (wrenGetMapCapacity / wrenGetMapEntry), which upstream Wren lacks; it mirrors Wren's own internal map_iterate. The additions are bracketed by --- calog patch --- comments. Re-apply them if the amalgamation is regenerated from upstream (util/generate_amalgamation.py).

  • Berry — Copyright (c) 2018-2026 Guan Wenliang and Berry contributors. MIT License. vendor/berry/ (see the upstream LICENSE).
