Install VS Code extension CodeLLDB (OS X/Linux)
Create this folder and file in project root:
.vscode/launch.json
E.g. two debug configs for tower package with and without using cargo:
{

"version": "0.2.0",
"configurations":
[
{
"name": "debug tower",
"type": "lldb",
"request": "launch",
"cargo": { "args": ["b", "-p", "tower"] },
"args": [ "--swarm-path", "./swarm_temp", "--swarm-persona", "alice", "start" ], // e.g. ["arg1", "arg2"]
"env": {
"MNEM": "talent sunset lizard pill fame nuclear spy noodle basket okay critic grow sleep legend hurry pitch blanket clerk impose rough degree sock insane purse",
"NODE_ENV": "test"
}, // e.g. {"ENV1": "aa", "ENV2: "bb"}
"cwd": "${workspaceFolder}"
},
{
"name": "debug tower without cargo",
"type": "lldb",
"request": "launch",
"program": "${workspaceFolder}/target/debug/tower",
"args": ["--swarm-path", "/opt/swarm_temp", "--swarm-persona", "alice", "start"],
"env":{"NODE_ENV": "test"}, // {"ENV1": "aa", "ENV2: "bb"}
"cwd": "${workspaceFolder}"
},
]
}
File -> Preferences -> Settings type Allow setting breakpoints...
Tick this checkbox:
<> Allow setting breakpoints in any file
Done!
Set your breakpoint and press F5 or menu -> Run -> Start Debugging.
If all goes well, debug sessions should start and you should see debug tower on upper-left hand of VS Code in debug window.
Note: You can see/select other debug targets if you added more than one package into "configurations": array in step 2.
