TerminalPager.jl 

julia> a = rand(100);

julia> a |> pager

和上面的方案有些不同，不是同时显示的，和 man 命令的操作方式类似。

See Provide a simple way to print all entries in a collection · Issue #29223 · JuliaLang/julia · GitHub

macro showall(expr)
    return quote
        show(IOContext(stdout, :compact => false, :limit => false), "text/plain", $(esc(expr)))
    end
end

@showall rand(100, 100)

我还在Issue里面看到了println.(x);的写法。

也挺奇怪为啥他们不觉得这个需要简单解决一下。
