Full review: https://github.com/clojure/clojurescript/compare/darwin:inline-source-maps~3...darwin:inline-source-maps

Also please note that the first patch testing original functionality fails in one test because there was a bug in timestamp formatting in :source-map-url case:

Today when testing Dirac I realised we need to embed sources contents as well.

Additional patch:

Tested in DevTools and works like a charm.

This would be helpful for us as well.

I have run across this one as well by following this tutorial.

Without either this patch or Dirac's complicated setup it is not currently possible to use node --inspect and debug correctly. The symptom I see on our side is that source maps are detected but for some reason Chrome DevTools does not show them in the Tree View.

The content of one of it is:

{"version":3,"file":"\/Users\/user\/cqrs-engine-cljs\/out\/cqrs\/event_store.js","sources":["event_store.cljs"], ...

Linking to patches outside of JIRA is not proper for tickets. Please add a single squashed patch to this ticket directly.

Attached it as a patch file.

Took https://github.com/darwin/clojurescript/compare/inline-source-maps~4...darwin:inline-source-maps.diff and applied it to current master. It applied cleanly without conflicts. Tests are still passing on my machine.

Patch no longer applies; needs re-baseline.

Newly when developing chrome extensions, source-maps got broken again[1]. Probably due to some added security restrictions in what Chrome allows Chrome DevTools to "see".

Some people on the interwebs claim that inlined source-maps are a possible workaround:
