I do something relatively similar with elinks to send opened torrents
to an mldonkey server. This is the code I have in my hooks.lua:
-- Save displayed torrent and tell daemon to download it.
function save_torrent ()
-- See if we can obtain the local document.
local doc = current_document()
if doc then
-- Create a temporary file
local tmp = tmpname () ..".torrent"
-- Write document into the temporary file.
writeto (tmp) write (doc) writeto()
-- Tell elinks to delete after this function.
table.insert (tmp_files, tmp)
-- Call the mldonkey daemon on the local temporary file.
return "goto_url", mldonkey_host.."dllink%20"..url_donkey(tmp)
end
end
-- Table of expressions which are recognised by our lua_console_hook.
console_hook_functions = {
...
torrent = save_torrent,
...
}
This works like this: you navigate your way to get a torrent, and
instead of offering a download it shows itself on the screen. Then I
press the console key, type "torrent" and the function is called. You
can modify the code of the save_torrent function to save the file,
call an external program to process it, then reopen it again as a
link to the local hard disk.
If you don't mind processing the web page in lua, you can do this
directly without temporary files in the pre_format_html_hooks,
which are precisely to clean HTML and stuff that looks odd in elinks.
Note, I'm using last pre-git version of elinks. This may have
changed a lot in the meantime.
