Example command plugin
Copy this to your ~/.voltron/plugins directory. It will be loaded when
Voltron is initialised, and register a debugger command that works as follows:
$ lldb /tmp/inferior
Voltron loaded.
Run `voltron init` after you load a target.
(lldb) target create "/tmp/inferior"
Current executable set to '/tmp/inferior' (x86_64).
(lldb) b main
Breakpoint 1: where = inferior`main, address = 0x0000000100000cf0
(lldb) run
Process 12561 launched: '/tmp/inferior' (x86_64)
Process 12561 stopped
* thread #1: tid = 0x1d33f, 0x0000000100000cf0 inferior`main, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1
frame #0: 0x0000000100000cf0 inferior`main
inferior`main:
-> 0x100000cf0: push rbp
0x100000cf1: mov rbp, rsp
0x100000cf4: sub rsp, 0x50
0x100000cf8: mov dword ptr [rbp - 0x4], 0x0
(lldb) example
rax 0000000100000CF0
rbx 0000000000000000
rcx 00007FFF5FBFFA70
rdx 00007FFF5FBFF978
rbp 00007FFF5FBFF958
rsp 00007FFF5FBFF948
rdi 0000000000000001
rsi 00007FFF5FBFF968
rip 0000000100000CF0
r8 0000000000000000
r9 00007FFF5FBFEA08
r10 0000000000000032
r11 0000000000000246
r12 0000000000000000

r15 0000000000000000
Provided you stick to the adaptor API that is implemented in every *DBAdaptor
class, custom command plugins should work across all debugger hosts.
This is a quick example that will only work on an x86_64 target.
