<saggit> I think the debug info should print something useful, instead of `???`,

<sdogruyol> Morning everyone
<FromGitter>
<JJJollyjim> @saggit what do you mean? I didn't truncate the output, are you saying there's an error in the error handling? ;)
<FromGitter>
<saggit> @JJJollyjim to be clear, i mean the crystal compile

<sdogruyol> --debug is not perfect

<FromGitter>
<JJJollyjim> Hold on shouldn't `--debug` affect the compiled program, not the error output of the compiler itself?
<FromGitter>
<JJJollyjim> Or is `--debug` explicitly for debugging the compiler?

<FromGitter>
<sdogruyol> nope
<FromGitter>
<sdogruyol> it's debugging for the program itself @JJJollyjim
<FromGitter>
<JJJollyjim> Yeah got it
<FromGitter>
<JJJollyjim> So should I open an issue about `crystal build` segfaulting?

<sdogruyol> well you could definitely open an issue for your specific usecase / program

<greentornado> hi what's the next release timeline :D with multithread support ? ;)
<FromGitter>
<bew> multithreading won't be in the next release :D but next release will be soon I think!
<FromGitter>
<akzhan> implemented as a dummy {% if false %} for now.

<bigtunacan> Is there a way to do step through debugger with Crystal?
<FromGitter>
<bigtunacan> Sort of like I can do in Ruby with the byebug gem?
<FromGitter>
<bigtunacan> or Visual Studio in .NET
<FromGitter>
<bigtunacan> Not that I would use .NET :O
<FromGitter>
<sdogruyol> lldb or gdb

<alibby_twitter> Sorry for the OT here, but anyone know how to submit a bug report to gitter? I can’t seem to find anything anywhere aloowing me to do so.

livcd, not to take things out of context,.. concurrency works but currently on one CPU core. but it's meant to look the same when multicore is implemented.

<straight-shoota> Is there an easy way to determine if a class supports json mapping?
<FromGitter>
<bew> using `responds_to?` on `to_json` & `from_json` maybe?
<FromGitter>
<straight-shoota> `obj.responds_to?(:json)` won't work because json module defines `to_json` and `to_json(io)` on every object

<akzhan> try to instantiate new JSON::PullParser. It will failed on compile phase unless mapped.
<FromGitter>
<straight-shoota> yes, but I want it do dynamically call `to_json` if the class supports it, otherwise to something else
<FromGitter>
<akzhan> No way unless you change JSON.mapping itself to provide this information.
<FromGitter>
<straight-shoota> ===2549 seems like an idea for this, but needs implementation===
<FromGitter>
<akzhan> Yes, it is
