^^^^^
Sorry, here is a bug, better would be $url.txt or even better replace it with:
open ELINKS, "|elinks -dump >> output.txt"

These three lines were in PERL. In PERL there was easy.
It dumps (in normal browsing mode) every visited page to the file
with filename equal to the url with extension .txt.
In second version dumps are apppended to the file 'output.txt'.
It is good for eg. dumping frames.
This works interactively. If you want to make it non-interactive, the easiest
will be to add 'exit' to the pre_format_html_hook.
In PERL that was three lines. I have no LUA installed currently, but that could
be done something like this in LUA:
function pre_format_html_hook (url, html)
local tmp = tmpname()
writeto(tmp) write(html) writeto()
execute("elinks -dump " .. tmp .. " >> output.txt; rm -f " .. tmp)
if match("our_pattern", url) then
exit
end
end
This code probably won't work, but when you read lua docs you'll correct it
without problems.
It should work like this:
- write html to the temporary file
- invoke elinks in dump mode on that file
- remove temporary file
- quit main elinks when there is such need by invoking exit
