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.

> Note: `vendor/mybasic/myBasic.c` carries one small calog patch (making the

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`).
