@Re-do completely the way that external modules are loaded in eawk.
For now, use a
use("digest")
style statement in the script to enable the bindings in a
libeawk-digest.so to be loaded via dlopen(3).
Also add readrec() and writerec() callbacks for use in embedded
programs, so that eawk can really be deeply embedded in other things,
and used as a command interpreter, etc.
Other headline changes include:
+ added gawk-style bit arithmetic ops
+ added gawk-style asort/asorti
+ added eawk_readrec() and eawk_writerec() callbacks for use
in embedded operations
+ added extension use via use() command
+ added extensions for
base64

The upshot is that we can extend awk quite easily, as shown by this example
script:
% cat scripts/conn2.sh
#! /bin/sh
env LD_LIBRARY_PATH=lib:extend/c bin/eawk -v host=$1 '
BEGIN {
use("c");
if (host == "") print "phooey#0";
addr["ai_family"] = PF_INET;
if (getaddrinfo(host, "http", addr) != 0) print "phooey#1";
sd = socket(PF_INET, SOCK_STREAM, 0);
if (connect(sd, addr["ai_addr"], addr["ai_addrlen"]) != 0) print "phooey#2";
s = sprintf("GET / HTTP/1.1\r\nHost: %s\r\nUser-Agent: eawk-2.1\r\n\r\n", host);
write(sd, s, length(s));
url = read(sd, 4096);
print url;
close(sd);
}'
