Error in examples

[c42f]

Hi @kdheepak, I just watched your JuliaCon talk and came here to try things out. However the examples don't seem to work on my Ubuntu 18.04 machine with gnome-terminal, Julia 1.4 and TerminalUserInterfaces 0.2.0:

julia> include("barchart.jl")

Any thoughts on what could be causing this?

@c42f Thanks for trying it out! We are currently trying to debug this here: https://github.com/kdheepak/TERMIOS.jl/issues/5

I don't have a linux machine, but if you are interested in trying out a few things maybe we can figure out what is going on? I posted some more information on the other thread.

I have the same issue. Anyway i can help?

I tired things on Fedora and Ubuntu, using different version of Julia and used different terminal emulators

[kdheepak]

Thanks for the report and the offer to help. Maybe we can figure out what is different between my set up and yours:

I set up an Ubuntu VM with a fresh installation of Julia v1.5.0 and clone'd TerminalUserInterfaces's master branch:

And the barchart example seems to be working.

I'm using the changes from this commit: c4a1dd920870ffd0fdd921c6a01d3b7dce564907

I am running 1.4 Julia. I did an

  [408767e4] ~ TerminalUserInterfaces v0.2.0 ⇒ v0.2.0 #master (https://github.com/kdheepak/TerminalUserInterfaces.jl.git)

But the problem still persists

[freemin7]

It works on Julia 1.5.1 with [408767e4-586b-40c7-9657-f9758988469a] but not on Julia 1.4.2 with [408767e4-586b-40c7-9657-f9758988469a]

[kdheepak]

Interesting! I'll try to reproduce on my VM and see what is going on there.

[kdheepak]

I've dropped the dependency on Termios, so this issue should be resolved in v0.3.0: https://github.com/kdheepak/TerminalUserInterfaces.jl/releases/tag/v0.3.0
