Gallium fails on master branch of julia

[josefsachsconning]

Is Gallium believed to work on the master branch of julia? I get the following.

julia> ARGS = ["3139"];

At f95b88c, I get

ERROR: LoadError: LoadError: could not open file /home/sachs/.julia/v0.5/DIDebug/src/DIDebugLite.jl

[Keno]

Sorry! I pushed the missing files, but this code isn't quite ready yet. In particular, there's a couple of commits which are still in pull requests on julia master before this will work.

[ScottPJones]

Which PRs are required? (for those of us willing to play around with merging them together and building on our local platforms) (Dying to be able to use Gallium!)

[ViralBShah]

I believe this works now.

[josefsachsconning]

It doesn't work for me, but I'm not sure whether it is supposed to work, since the README.md was replaced.

julia> ARGS = ["17359"];

[josefsachsconning]

The two examples in the README also do not work for me (the second with the same error reported by Viral in issue #53 )

[Keno]

For that error message, try Pkg.checkout("MachO"). For the second one, I need to update ASTInterpreter, since this recently changed on julia master.

[josefsachsconning]

I did Pkg.checkout("MachO") and I still get the same error.

[Keno]

Oh, hold on, you're not on OS X, I got confused. Try Pkg.checkout("ELF") and Pkg.checkout("DWARF"). I'm not sure what your current setup is, so I don't know which packages are outdated, but those would be my guess. If that doesn't work, please see if any of the other packages mentioned in the README are not updated. The installation process will get a lot simpler, once we tag these packages, but for now you need the master branch for a bunch of them.

[josefsachsconning]

After Pkg.checkout("ELF") and Pkg.checkout("DWARF"), the first example works for me.

[Keno]

Ok, great, you'll probably run into the same error as in the second example very soon while trying it out, I need to fix that first.

[josefsachsconning]

I gather that the old modes of operation in the September preview no longer work?
E.g., debugging is no longer performed from a separate julia debugger process?
Also, js, jp, jbt etc. are gone?
Is there any documentation available for the new version?
Maybe a replacement for your (Keno's) "Demo of Gallium.jl - the Julia debugger" YouTube video in the works?

[AndyGreenwell]

See https://github.com/Keno/ASTInterpreter.jl for various commands.

[Keno]

There'll be lots of documentation, etc. However, for now I'm focusing on getting the last couple of things I now are broken into working order before doing that polish. https://github.com/Keno/ASTInterpreter.jl does have a partial list of commands for the interpreter.

[ViralBShah]

Can we link those docs in the Gallium README, since many people are likely to come to Gallium.jl for the debugger?
