2001-Nov-07 17:17    1.1    Check-in [1265]: HEADS UP, guys:

Here comes the first cut for the long-awaited channel tree specification parser and channel tree builder. This certainly makes L2 finally THE killer library in the logging field. Woohooo... and the crowd goes wild!

It allows one to build an arbitrary complex logging channel tree out of a single textual specification. An example follows:

    noop -> {
        prefix(prefix="[%d-%m-%Y/%H:%M:%S] %L test[%P]: ", timezone="local")
        -> filter(regex="hecking", negate="0")
           -> buffer(size="800")
              -> file(path="l2_test.log",append="1",perm="420");
        error: syslog(ident="L2-Test", facility="user",
                      remotehost="en1", logpid="1", target="remote");
        panic: smtp(rcpt="rse@engelschall.com", host="en1", port="25"

This allows one to log nice timestamp-prefixed messages containing the word "hecking" to a buffered file. Additionally if the message has a level higher or equal to "error" it also logs it remotely via UDP to the syslogd on en1. And additionally if the message is a panic message, it is also sent out as an Email via SMTP to the MTA on en1.

Ever thought a C library has to be dull and simple? ;)

PS: This stuff certainly needs more polishing and cleanup and also a few things I'll enhance in the future (for instance to remove the restriction that parameter values have to be in quotation marks, etc.). By rse.
