Log Message:
Changes to eawk:
+ add a small script to do some basic json printing
+ add a small http daemon library - which only does GET requests,
but still useful. Also add an eawk script, which acts as a web server
in 9 lines of awk:
env LD_LIBRARY_PATH=lib:extend/httpd bin/eawk -v port=${port} '
BEGIN { use("httpd")
server = httpd_bind_server("localhost", port, "ipv4")
while (1) {
client = httpd_get_connection(server);
uri = httpd_read_request(client);
filename = httpd_parse_uri(uri)
httpd_serve_static_content(client, filename);
httpd_close_client_connection(client);
}
}'
and in use:
% sh scripts/httpd.sh 12345
