You can start a simulator on host instead.
Copy code
jag simulate
I think that will just show up when you do 
jag scan
.
Yeah, that seems to work also with 
jag watch
.
k
it works very nice 🤩 thank you !

Note that you can pass arguments to your application by taking an argument with 
main
. Use 
--
to tell Jaguar that the arguments are for the Toit program. 
jag run -d host foo.toit -- --arg-to-foo
k
🤔 (I think to be slow on the uptake) - please give me an example for that
f
Copy code
main args:
  print args
jag run -d host demo.toit -- 1 2 --another-arg

👍🏻 tested and got it. I think the simulation mode (running toit on Host/PC) is VERY helpful to test the behaviour of unknown functions,classes,packages,... (especially when there are no adequate examples)

I think that's for the shell (bash...) So it autocompletes the subcommands (like 
run
).
Jaguar also contains the 
lsp
command which is used by the vscode plugin for completion and diagnostics there.
