Many thanks for your reply, Hans. Is there a way to hyperlink to an attached document? I mean, no matter whether it has been generated by ConTeXt or not. Many thanks for your help, Pablo -- http://www.ousia.tk

Is there a way to link to a page or a destination (such as in https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#page=... or https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#named...) to a document that is attached (using \attachment) in ConTeXt?

Many thanks for your reply, dr. Hans van der Meer. Sorry, but I’m afraid I don’t see the way of generating an URL to a non-external document in your code. After all, the document is embedded in the PDF document itself. Pablo

% Return the code when clicking the link. \def\URIReturnCode#1{\ctxlua{tex.print(hvdm.urireturncode("#1"))}}

— Some Lua code needed: -- Check URI

socket.http.TIMEOUT = 5-- set URI timeout in seconds hvdm.urireturncode = function (theuri) -- Differentiate between file and http protocols. local first,last = string.find(theuri, "file://") if first == nil then -- We have http to search for. local content, status, authinfo = socket.http.request{ method = "HEAD", url = theuri, } return type(status) == "number" and status or "failure" else -- We must ascertain the existence of the file. local thefile = io.open(string.sub(theuri, last+1, -1), "r") if thefile then io.close(thefile) return "200" else return "404" end end end

BTW if you don’t know a reference name (from a foreign PDF), you can link to the page like this: \goto{TEST}[../../somepdffile::page(23)] i.e. it works even with paths. Greetlings, Hraban --- https://www.fiee.net http://wiki.contextgarden.net https://www.dreiviertelhaus.de GPG Key ID 1C9B22FD
