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,
Jelle

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

Hi Philip,
Thank you, that was precisely what I was looking for. I knew that I had
seen LuaSocket before, but I could not find it.

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.

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
