v1 Missing show for media MIME?

[JonathanAnderson]

I'm trying to get this to work for me in v1 since I used to love using this tool. I havent been able to get it to work, so i've put together what I think a MWE is and I'm running into a missing show method for a Base64EncodePipe. I

I've put this tiny png image into an buffer and try to display it directly as follows

~/root/usr/install/julia/julia 2>stderr.log

so I define Base.show and added an IO field to the InlineDisplay so I could send output to stderr and pipe that to hd to see what was going on and this is what I got.

julia> Base.show(io::IO, ::MIME"image/png", x) = show(io, x)

julia> display(TerminalExtensions.iTerm2.InlineDisplay(stderr), MIME("image/png"), x)

julia> flush(stderr)

When I manually base64encoded the buffer, it didnt look like this either.

Is this user error or is something broken here?

[JonathanAnderson]

I was expecting something more like this

julia> base64encode(x)
"iVBORw0KGgoAAAANSUhEUgAAACAAAAAgAQAAAABbAUdZAAAABGdBTUEAAYagMeiWXwAAAFtJREFUeJwtzLEJAzAMBdHr0gSySiALejRvkBU8gsGNCmFFB1Hx4IovqurSpIRszqklUwbnUzRXEuIRsiG/SyY9G0JzJSVei9qynm9qyjBpLp0pYW7pbzBl8L8fEIdJL9AvFMkAAAAASUVORK5CYII="

[JonathanAnderson]

If I change TerminalExtensions.jl:95 from

show(Base64.Base64EncodePipe(buf),m,x)

to

write(Base64.Base64EncodePipe(buf),x)

Then TerminalExtensions works for me again.

But I'm not sure what the expected behaviour of show for a MIME type is supposed to be..
