Tangentially related to unrepl but this could benefit from machine printing and elision:

yeah, anything tree like really

but tracing is a great example of that

I wonder if it works in cljs as well

nah I use the java debugging ifrastructure to have this level of tracing

in fact it’s a JVM tracer

do V8 or JSCore have a public debug API?

This is what i have found: https://nodejs.org/dist/latest-v8.x/docs/api/tracing.html

That JVM tracer is cool, how do you hook it up?

I guess it is in clojure.tools.trace ?

no it’s a new development, tools.trace works by redefining vars

In my case the JVM has to be started with -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=n (no explicit port required)

and then I have code to connect the JVM to itself as a debugger

Well that is great, node has a debugging/inspecting layer, not an expert however and it looks very limited: https://nodejs.org/dist/latest-v8.x/docs/api/debugger.html

A bit rudimentary indeed

@cgrand debugging/tracing/repl-driven development could be a killer feature of nrepl

next step is to open a new repl when an exception is thrown

@richiardiandrea you can attach chrome to a running nodejs instance for a full blown debugger

Yeah I have recently enabled boot to work with Dirac for a Repl in there for my colleagues 😀

But it is not the same thing 😀

And I don't personally use it, at some point I will help porting unrepl to cljs just don't have enough time now and when I have time, it is too little and I prefer to tackle smaller problems

re: cljs port, dynamic ns are not seen by require (self-hosted) so: • either add workarounds in the blob • fix cljs. What’s the best course of procrastination? 🎵

@cgrand I guess you spoke with D. Nolen already? What did he say? Usually patches to self host are more likely to happen, especially because you have very active projects/maintainers behind it

@richiardiandrea I forgot you opened the issue for that

the fix should cover both slef-host and regular 😕 to not create yet another divergence

Ok yeah that is tougher then, Darwin already proposed something and got bounced 😀

(don't remember the details now)

🎶 procrastination isn't good for me 🎶
