Subject: piping output from external command
Date: Sun, 30 Jan 2011 23:19:00 +0100 [thread overview]
Message-ID: <87vd16avcb.fsf@micropit.couberia.bzh> (raw)
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... ;)
