Original GitHub issue: https://github.com/rivo/tview/issues/10

First of all, I have to say this is a cool looking library with some neat code. The demos all work well apart from the one in demos/presentation. I CDd into the folder and ran go run main.go but i got the response:

# command-line-arguments
./main.go:35:3: undefined: Cover
./main.go:36:3: undefined: Introduction
./main.go:37:3: undefined: HelloWorld
./main.go:38:3: undefined: InputField
./main.go:39:3: undefined: Form
./main.go:40:3: undefined: TextView1
./main.go:41:3: undefined: TextView2
./main.go:42:3: undefined: Table
./main.go:43:3: undefined: Flex
./main.go:44:3: undefined: End
./main.go:44:3: too many errors

I expect I have inadvertently missed out an important step. But which one?

The presentation code is spread across multiple files. go run *.go should do the trick.

Wow! That was quick! Thanks.
Just one thing now, I seem to be stuck on Page 7 "Text 2" - no key that I can find moves the page forward or back.

I obviously didn't try escape. How embarrassing!

It's not obvious, I admit. But since the primitives that are shown are interactive and they have their own key bindings, sometimes Enter has a different meaning.

I actually built in a short cut: Hit Ctrl-N to advance to the next slide, Ctrl-P for the previous slide.

Great. Thanks for that. It's a really impressive library. I've tried a few CLI tools with Golang but this one looks easier to use, with a nice fluent approach, and your color choices are good!

Maybe a Readme could be added to the demos subdirectory pointing out the convention of running *.go? I ran into the same issue. Maybe it's only an issue for people new to Go, but as a person relatively new to Go looking to use this library, it did introduce a tiny amount of friction.
