Hi there,

I would like to use imposition to rearrange an existing PDF as a booklet, but I don' have ConTeXt installed on the machine I would like to do it.

Using http://live.contextgarden.net/ might do the job, but I have problems to load the local file.

Is there any way to load a local file (or even an URL) with ConTeXt? How should I rewrite the following command to load a local file or an URL in ConteXt live?

In mkii, this is simply impossible.

If you have the program "curl" installed, you can use an url as a file name in context mkiv.

300kb extra in the binary and an extra portability headache. Luatex actually includes the luasocket libraries, so that would be a better option, but it takes time to write the code for a http/ftp fetcher to replace curl completely. If you (or someone else) is interested in writing a replacement for luat-crl.lua, have a look at: http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/ The bare bones usage (for http) is as simple as this: local http = require("socket.http") local content, responsecode, extra = http.request(arg[1]) io.write (content) but in real life, you have to deal with partial content, errors codes, url escaping, etc. etc. Best wishes, Taco

I don't understand all the trouble... This works very well on live.contextgarden.net (luatex): \starttext bla \externalfigure[http://pmrb.free.fr/tmp/hacker.jpg] bla \stoptext Fetching a pdf instead of a jpg should be possible too, I believe... Cheers, Peter -- http://pmrb.free.fr/contact/

\insertpages[original_file.pdf][width=0pt]

I did not find any documentation about \insertpages[][] but I've just tried it out:

\starttext \insertpages[http://meeting.contextgarden.net/2008/talks/% 2008-08-21-taco-luatex/luatex-talk.pdf][width=0pt] \stoptext

It just works!

Many thanks for your help, Peter. Pablo
