piping output from external command

30 Jan 2011

      Hello,

This used to work with pdftex:

\starttext
\input "\string|echo hello world"
\stoptext

What's the recommended way, to do this in mkiv?

I've defined \Pipe{} like this:

\startluacode
userdata = userdata or {}
function userdata.pipe(c)
    local h = io.popen(c)
    context(h:read"*a")
    h:close()
end
\stopluacode
\def\Pipe#1{\ctxlua{userdata.pipe"#1"}}

But I suppose that there is already a nice command in the core... ;)
