How to handle exceptions from emscripten_run_script?

[tuket]

Hi,
I'm using emscripten_run_script to run some arbitrary JS code.
I can't guarantee that the JS code is correct.

Right now when there is an error in the JS code I get an exception, and the application can't continue. I would like to avoid that; the application should log the error and continue.

I have tried different things:

• Wrapping the JS code with a try-catch "try {" + str + "} catch(err) { console.log(err.message); }"
• Do the try-catch in C++: try {emscripten_run_script(str);} catch (...) {};
• Add -fexceptions flag to compiler and linker

But none of then seem to work. What should I do?

Thanks!

The first option should work, if you do it on the JS that is sent to emscripten_run_script. If not, perhaps there is a typo in the try-catch or elsewhere? (that would throw before it runs the code) Or perhaps it throws in the catch body? (do all thrown err have the property err.message..?)

You are right, after doing a clean recompile it worked. Thanks!
