Support for stepped execution?

[djMax]

Is it possible to step through execution (to form the basis for a debugger)?

[Siubaak]

A little bit difficult. Actually debugger statement is supported, but I just found there's a bug of the minimized version and I will fix it soon.

[Siubaak]

Debugger statement has fixed for minimized version. I will try to add a step method for executing the code step by step in the future.

@Siubaak - Adding a mechanism for step-by-step execution (along with a callback API to process after each step operation and some API to examine locals on the stack, etc) would make this project very, very useful to me. I am trying to build a lite version of the Chrome DevTools debugging environment, so you can imagine what type of API I would need to introspect the stack, locals, etc. as the user steps.

Thank you for this cool project! :-)

I found a repo that may meet you guys requirement

JS-Interpreter by @NeilFraser is the best one I have found for stepped execution.

@carloslfu, JS-Interpreter only supports ES5 and you would have to transpile :/. Also the API is not as pleasant as with sval.

Is there any update here?

Can I debug sval executed scripts in the chrome dev tools?

Currently I don't have spare time to finish this feature.

If you guys want to step through execution or debug scripts in browser/node.js/jscore... environment, highly recommend vDebugger. And it has a higher performance than Sval. @beetaa @ShotiQ @scgm0 @bedney @djMax
