I am suspecting that Firefox has made changes to its browser program and that Is why it no longer opens the website. If you're familiar with other C++ debuggers, this option is similar to the set substitute-path command in GDB or a target.source-map setting in LLDB. Open Chrome DevTools, click the gear ( ) icon in the top right corner of DevTools pane, go to the Experiments panel and tick WebAssembly Debugging: Enable DWARF support. And that might explain why your problem is transitory; if Firefox is opened via an external link by the operating system, that desktop shortcut option wouldn't come into play. Avoid support scams. In security engineering, countermeasures When you use WASM, does the Chrome app store require the source code for code review before publishing? You can use it to remap arbitrary paths and help the DevTools locate sources. There are two main benefits WebAssembly provides: The kind of binary format being considered for WebAssembly can be natively decoded much faster than JavaScript can be parsed ( experiments show more than 20 faster).

Let's resume execution a few times and we can see how the inner x is changing as well-either by looking in the Scope view again, adding the variable name to the watch list, evaluating it in the console, or by hovering over the variable in the source code: From here, we can step-in or step-over C++ statements, and observe how other variables are changing too: Okay, so this all works great when a debug information is available, but what if we want to debug a code that wasn't built with the debugging options? This is the low-level textual representation of a .wasm module shown in browser developer tools when debugging. Let's start with the same simple C example as the last time: To compile it, we use latest Emscripten and pass a -g flag, just like in the original post, to include debug information: Now we can serve the generated page from a localhost HTTP server (for example, with serve), and open it in the latest Chrome Canary. It is also designed to run alongside JavaScript, allowing both to work together. Microsoft stated clearly in their roadmapthat a version of support will be in preview shortly.
