panic: invalid arguments

I am getting the below error when trying to run wuzz with no arguments. I am using ubuntu bash on windows to run this.

@achernyak what's your Go version?

[hackeryarn]

I was originally on 1.7.4 then I tried upgrading to 1.8.0 and still the same exact error.

[asciimoo]

@achernyak what is your operating system/terminal? Seems gocui cannot start in 256 color mode.

[hackeryarn]

@asciimoo I am on windows 10 running Bash on Ubuntu on Windows. It seems that they do have 256 color support and my terminal is identified as xterm-256color by default. I do believe this is a platform specific issue since it works everywhere else. So might be worth just putting in a note about support.

[asciimoo]

@achernyak could you confirm that fa4c1e8 solves the problem?

[hackeryarn]

Thanks for the really quick work around on this. However, it looks like there is still an error further down the code. The error moved now.

[asciimoo]

So the problem isn't the 256 color mode.. strange..

[hackeryarn]

@asciimoo It is still getting thrown in the same expression actually. OutputNormal seems to be throwing too. I was trying to set it to OutputGrayscale which seems to be supported by termbox which is used by gocui but gocui doesn't export it as an options.

[asciimoo]

@achernyak does OutputGrayscale work in your terminal?

[hackeryarn]

@asciimoo no still no luck with it. I was not able to get it to set to OutputGrayscale looks like gocui only supports OutputNormal and Output256.

[asciimoo]

@achernyak you can cast it to the correct type:

g, err = gocui.NewGui(gocui.OutputMode(termbox.OutputGrayscale))

[asciimoo]

@achernyak could you test e6f5674 ?

[hackeryarn]

@asciimoo unfortunates it looks like I am still getting a panic there...

[asciimoo]

Hmm, then, the problem isn't the color mode..

I ran into a similar issue while working with gocui on WSL Bash on Windows.
I think the root cause might be: microsoft/WSL#601
