@iron_debug foo(): run foo() inside the debugger.
When a breakpoint is hit, then you will be given an Iron REPL to work with-in,
allowing you to view/manipulate the arguments.
set_breakpoint(f): Set a breakpoint on call to the functionf
MagneticReadHead is very early alpha. THere are some otehr debugging projects going on, and you can certainly mix and match within the same project depending on your needs.
The other projects are also alpha, but almost certainly more mature than MagneticReadHead.
Rebugger is the another debugging package for Julia. Rebugger is a very nontraditional rebugger, MagneticReadHead is a lot closer to a traditional debugger.
Rebugger has has a user interface based on scooping the code of any function it steps into, into the REPL. Then allow you to point your cursor at a function and step into that one. Rebugger lets you edit the code at each step. MagneticReadHead lets you run code to inspect variables or save data, but you can not edit the code itself.
You can step backwards up the call-stack in Rebugger, MagneticReadHead does not support that (yet). MagneticReadHead lets you set breakpoints (on function calls), Rebugger does not support that (yet).
MagneticReadHead currently only lets you examine the arguments going into a function.
Rebugger lets you manipulate the function body however you want (So you can add @show to examine the local variables.
Rebugger is based on Revise.jl, MagneticReadHead is based on Cassette.jl and uses Revise.jl as a helper library.
ASTInterpreter2 is another debugger for julia. Apparently it is working in 1.0. Who knew ? (not me :-P) I don't think it has breakpoints yet, but it's stepping is a lot more advanced/fine grained.
I need to check it out
