Re: RFC fetcher

I was looking for some rfc today so I thought I might use your code.
Of course I modified it, because I want to keep the rfc's I get. So I added a check if that rfc exists in my rfc-directory, if not it gets the rfc and writes it to a file. Works nicely.
I would like to prepend a search tool for the index, so you can search for a rfc by topic. Perhaps I'll add that when I have more time.

Re(2): RFC fetcher by yakko (Friar) on Apr 04, 2001 at 21:29 UTC
Great ideas! Here's my implementation of the first idea: #!/usr/bin/perl -w # example usage: rfc 1459 (gets the IRC RFC) use strict; use LWP::Simple qw(get); die("usage: rfc <rfc#>\n") unless defined($ARGV[0]); my $rfcnum=$ARGV[0]; my $base="http://www.rfc.net/rfc"; my $rfcdir="$ENV{HOME}/rfcs"; my $rfcfile="${rfcdir}/rfc${rfcnum}.txt"; my $rfc; if(-e $rfcfile) { open(RFC,"<$rfcfile") or die("open($rfcfile): $!\n"); local $/ = undef; $rfc=<RFC>; close(RFC); } else { $rfc=get($base.$rfcnum.".txt"); open(RFC,">$rfcfile") or die("open($rfcfile): $!\n"); print RFC "$rfc"; close(RFC); } print "$rfc"; __END__ [download] (Update: Just when I thought I had it nailed, better ideas crop up. Now reading docs to retool to merlyn's idea below. (tho rfc.net doesn't appear to return the proper headers that support `mirror()`)) -- Me spell chucker work grate.

I'd use LWP::Simple's `mirror($url, $localfile)` in place of the if/else test. That way, if they update it, you'll get the latest version, and if it hasn't changed, it's still minimal traffic. It also automatically avoids creating the local file if the remote fetch failed, so you won't end up with an empty RFC file if something's broken. -- Randal L. Schwartz, Perl hacker	[reply]
