Hello all,

I'd like to typeset an RSS feed and I was wondering whether I could instruct ConTeXt to fetch the contents of a url like: http://feeds.bbci.co.uk/news/rss.xml Thanks for any pointers,

the fetching part is easy as we have LuaSocket: ········································································ \starttext \startluacode local bbc_rss = socket.http.request"http://feeds.bbci.co.uk/news/rss.xml" context["type"](bbc_rss) \stopluacode \stoptext \endinput ········································································ In your document, however, you will want to save the file locally for a given Context session and reuse the local copy to avoid re-fetching it on every pass. Maybe use the timestamp to force a fresh fetch after some time. Regards Philipp

I was also recently thinking along these lines (set a cron job to typeset RSS feed into pdf and email to kindle). So, please release your code once you are done.

and I was wondering whether I could instruct ConTeXt to fetch the contents of a url like: http://feeds.bbci.co.uk/news/rss.xml

Suppose you write a macro \processrssfile{...} that takes a local rss file and typesets it, then you can simply call \processrssfile{\locfilename{http://feeds.bbci.co.uk/news/rss.xml}} to process a remote file. ConTeXt downloads and caches the file. On subsequent calls, the cached file is used. IIRC, the cache remains valid for a day and it is possible to change the threshold after which a new file is fetched. FWIW, I have added this to t-vim.tex so it can pretty-print remote files. This only works with http:// or ftp:// and not with https:// Aditya
