Licensing
JSTime itself is MIT-licensed.
JavaScriptCore
Section titled “JavaScriptCore”JSTime statically links JavaScriptCore (and WebKit) which is LGPL-2 licensed. WebCore files from WebKit are also licensed under LGPL2. Per LGPL2:
(1) If you statically link against an LGPL’d library, you must also provide your application in an object (not necessarily source) format, so that a user has the opportunity to modify the library and relink the application.
You can find the patched version of WebKit used by JSTime here: . If you would like to relink JSTime with changes:
git submodule update --init --recursivemake jsczig build
This compiles JavaScriptCore, compiles JSTime’s .cpp bindings for JavaScriptCore (which are the object files using JavaScriptCore) and outputs a new jstime binary with your changes.
