QUESTION

Use QuickJS to modify preferences and global variables

Asked 2021-Nov-30 at 14:37

I am interested in using QuickJS to modify preferences in a C++ app. So, there is a preference variable called int myPref = 0

I want to expose this as a JS variable called jsPref

Then the user can modify this directly via JS using jsPref = 1

This can be extended to a struct - where one can define struct myPref { int a, int b}; which is exposed as a global in JS as jsPref

Inside the JS script, I wish to call

Take a look at e.g. JS_AddIntrinsicAtomics in the QuickJS source code. It uses JS_SetPropertyFunctionList to create an object whose properties are defined by a simple array of structures, with the help of some convenience macros.

Instead of JS_CFUNC_MAGIC_DEF, you can use JS_CGETSET_DEF or JS_CGETSET_MAGIC_DEF to define custom properties with getters and setters. Since the contents of the JSContext structure are not exposed in the public API, you will have to use JS_GetGlobalObject to access the global object. Otherwise though, what you need to do is substantially the same.

This should look something like this:

For anyone who might stumble on this in the future, this was due to incorrect API usage. The leak wasn't due to the JavaScript code itself, but rather because JS_Eval() returns a JSValue, which needs to be freed using JS_FreeValue().
