panic: runtime error: index out of range

[dharrigan]

Hi,

Interesting project, got a panic:

% vsh         
http://vault:8200 /> cd 
panic: runtime error: index out of range

goroutine 1 [running]:
main.executor(0xc00001e216, 0x3)
	/home/fishi/Workspaces/fishi0x01/vsh/main.go:65 +0x6c5
github.com/c-bata/go-prompt.(*Prompt).Run(0xc0001ac400)
	/home/fishi/Workspaces/fishi0x01/vsh/vendor/github.com/c-bata/go-prompt/prompt.go:85 +0x7f2
main.main()
	/home/fishi/Workspaces/fishi0x01/vsh/main.go:144 +0x51a

I did this by simply running up vsh, selecting cd and pressing return without choosing the suggestion.

In fact, it seems to happen with all suggestions, without choosing the suggestion, i.e., cp, rm etc...

Yes you are absolutely right. Some sanity checks are still missing. Will add them later today 👍

Merged a fix with some basic sanity checking which should prevent panics like above.
However, more sanity checks / better error handling will be added in the (near) future.

Fantastic. Will test.

Yup, much better - no crashing 👍 Thanks for fixing!
