Thank you for creating useful tools.
A problem occurred when installing.

I did:

$ go get -d github.com/skanehira/docui
$ cd $GOPATH/src/github.com/skanehira/docui
$ GO111MODULE=on go install
$ docui
panic: invalid dimensions

goroutine 1 [running]:

Thank you issue.
If screen size is too small, it will not work.
Please increase the size of terminal and tell me whether it works or not.

I'll resolve this bug in the near future.

@skanehira
Thank you.

I was increase the size of terminal.
It's worked.
Specifically, it is full screen size.

I think, an error occurs if the number of rows is less.

That right.
If screen is too small, docui cannot draw screen.
That is gocui's specification.

I see.
Thank you!
