Hello everyone,
I’m new to Ruby and not so experienced programmer in overall but i
manage to do “ok”. Now I started to program a bit in Ruby and wanted
to write a logWriter program but the problem is that Ruby doesnt have
I/O Stream functions like java and C++.
I have never written a simple log writer before either, this will be
challenging. Is there any advice on how to proceed you could give a
fellow rookie ruby lover?
Cheers,
RubyNub

Instead it has a quite capable File class.

Take a look at log4r (http://log4r.sourceforge.net). It aims to
resemble log4j/log4cpp as much as possible.

log_fd = File.new(“test_log”, “w+”)
or just open an existing one
log_fd.write(str)
or
log_fd << “str”
log_fd.flush
you can also use sprintf
log_fd.write(sprintf “%d”, var)
log_fd.close
have a look to
http://www.ruby-doc.org/core/classes/IO.html
is this you are looking for?

Ooh. From personal experience log4r is rather poorly documented (in
bad moods I’d call it abysmal, but right now, I’ll just say poor). If
you have trouble, just post it here and folks who’ve used it will
help.
I’m trying to find the script I had that used it extensively to show
another example, but it may have gotten purged…

Thanks Vlad, I will take a look at it right now.

You could read the standard logger library which is pretty easy to
follow.

Hello!
What I want do do is to make a logwriter so I can store the
information that comes in from a given network. For example I would
like to see what kind of data I’m receiving from that network by
having this logwriter storing that info for me.
there is doc for the socket class, this is much easier to write the
whole stuff then in C
http://www.ruby-doc.org/stdlib/libdoc/socket/rdoc/index.html
maybe this is interessting for you
http://www.ruby-doc.org/stdlib/libdoc/drb/rdoc/index.html
http://www.chadfowler.com/ruby/drb.html
I went and looked at this link: (http://log4r.sourceforge.net)
But that is a completely done written logging program right? What I
would want do to, is to write one of my own. I thought they were
simpler than that… CAn you give mne advice on how to proceed?
components should be (apart from write and read methods) in my
logwriter…
I don’t know either, I am sorry. I never write a logwriter before, I
just logged some messages with the classes above (socket and DRb).
