Well, I tried writing a socket proxy via pipes - it worked in my test code, but not within the full application. Anyway, since Tango has network support, would it be simple to add networking to minid? Jarrett? :)

Nothing fancy, something along the lines of...

Code:
namespace net
{
    function inoutSocket() { }

    class Socket : InoutStream
    {
        function rawRead() { }
        function readln() { }
    }
}

local socket = net.inoutSocket( "irc.freenode.net", 8001 )
// implicit socket.connect()?
socket.setTimeout( 0.001 )
local buffer = Vector( "u8", 4096 )

socket.write( "user maustin2 0 0 :Mike Austin\r\n" )
socket.write( "nick maustin2\r\n" )

while (true)
{
    local buffer, length = socket.rawRead( 4096, buffer )

    if (length > 0)
        writeln( buffer )
   
    time.sleep( 1.0 )
}

I'm itching to write an IRC client for minid-inertia, a Windowing System and UI Framework. http://mike-austin.com/inertia/minid/minid-inertia-2.png

Ooooh. Depending on how it turns out, I could have use for this also. Any chance of getting Selectors available as well?

That could be in the cards. I think I'll just try getting the basic sockets in first and then work on adding more features.

I haven't been doing nothing about this Razz

I was using Tango 0.99.8, but the problem with that is that its socket implementation doesn't support timeouts on anything other than reads. Also, the tango.net package is getting some reorganization and simplification post-0.99.8, and I don't want to write a library that's based on stuff that has already been obsoleted.

I thought Tango trunk had an issue whereby timeout-capable operations weren't yet implemented on Linux, which seemed like a big problem (and would obviously make it useless for maustin), but I now realize that it's only the operations that are part of the new auto-IO-fiber-scheduling stuff that are unimplemented. Normal timeout reads/writes are supported. (Oddly not connects, even though they can be done asynchronously.)

So now that I've updated the code to Tango trunk, I'll work on it for reals Razz
