Gallium.jl

Yup, Gallium used DWARF debug info like gdb/lldb and could debug optimized, compiled Julia code. It's named Gallium because the DWARF standard constant for the Julia language is 31 and gallium is the 31st element in the periodic table :) Unfortunately, compilers generate horrible debug info and it was very hard to get even basic stuff like knowing the values of all in-scope local variables to work reliably and making breakpointing work was very much a work in progress. Debugger.jl on the other hand is slow, being interpreter-based, but very reliable. The down side is that it's really slow, so if you need to debug performance intensive code, you might be in trouble. In the future, the plan is to steal tech from Gallium [1] and MagneticReadHead [2] and use them to create a hybrid interpreted/compiled debugger that is as reliable as Debugger

https://github.com/Keno/Gallium.jl for the debugger. It was still a bit unstable last time I tried it. One of the biggest problems that I had with Julia (which is one of the main reason I stopped using it) was the flexibility of the . notation. I use this feature in Python and Matlab a lot and I had some serious trouble trying to make it work or finding examples on how to use it. Though I think this problem will be fixed as the community grows. What are you referring to? Properties?

I'm not aware of any pull-requests implementing an incremental GC with pinning support, or any alternative module/namespacing scheme. Those would certainly be welcome. As I said, the people actively working on the compiler have to prioritize because time and resources are finite. This is not the same as anyone being "dead set against changing", or a "ban people for making too much noise about it". > when did any of them last move. Here's a sampling of some improvements over the past 4 months. - Debugging, everyone's priority by astronomic margins, has seen massive work and a recent preview-release (I've been using it since the announcement: rough edges, but very solid core): https://github.com/Keno/Gallium.jl/commits/master https://github.com/Keno/ASTInterpreter.jl/commits/master https://github.com/JuliaLang/julia/pull/15859 https

There's now a true debugger: https://github.com/Keno/Gallium.jl Only works on master 0.5-dev right now, but it's coming along nicely.
