Generate the source code representing the body of a function, minus the function keyword, name, parameters, and braces.


JSString *
JS_DecompileFunctionBody(JSContext *cx, JS::Handle<JSFunction*> fun, unsigned indent);
Name Type Description
cx JSContext * The context in which to decompile the function. Requires request. In a JS_THREADSAFE build, the caller must be in a request on this JSContext.
fun JS::Handle<JSFunction*> The function to decompile.
indent unsigned If it's not JS_DONT_PRETTY_PRINT, JS_DecompileFunction returns pretty printed source code of the function.


JS_DecompileFunctionBody generates the source code of a function's body, minus the function keyword, name, parameters, and braces, from a function's compiled form, fun.

If successful, JS_DecompileFunctionBody returns a string containing the source code of the function body. Otherwise, it returns NULL.

The source code generated by this function is accurate but unadorned and is not suitable for recompilation without providing the function's declaration. If you decompile a function that makes a native C call, the body of the function only contains the text "[native code]".


To decompile a complete function, including its body and declaration, call JS_DecompileFunction instead.
