Compiles a string containing Javascript to an ESTree object and/or executes an ESTree object in Javascript
Dette scriptet burde ikke installeres direkte. Det er et bibliotek for andre script å inkludere med det nye metadirektivet // @require https://update.greasyfork.org/scripts/506614/1441300/ESTreeProcessor.js
This library is intended to be used by userscripts that need to execute arbitrary JS code in string form, but are restricted by CSP unsafe-eval limitations.
This library uses esprima-next (ES2022) behind the scenes to compile ESTree objects.
Example:
var tree = ESTreeProcessor.compile('function test(b) { return b + a; } test(2);');
// tree contains an ESTree object
// Access to environment variables in the execute function is limited to what you pass in the second argument.
// This makes it safer to execute arbitrary strings, but the strings MUST be controlled at their source
// and/or processed and verified in code to be truly safe.
var result = ESTreeProcessor.execute(tree, { a: 3 });
console.log(result.output);
// logs '5' to the console
