[Pharo-project] Sockets in Pharo CollaborActive Book
by Sean P. DeNigris Sept. 1, 2010

Sept. 1, 2010

The description of sockets at http://book.pharo-project.org/book/networking/Socket/ is: Socket is one of the main networking classes. You can create a new TCP socket with the message #newTCP. > > This example creates a TCP socket and puts it into listening mode. After a > client has connected, it reads data from the socket. > > | server client | > server := Socket newTCP. > server listenOn: 12345 backlogSize: 4. > server waitForConnectionFor: 600. > client := server accept. > client receiveData > Huh?! It looks like half the code in this snippet belongs on the server, and the other half on the client. I tried: Server doit: server := Socket newTCP. server listenOn: 12345 backlogSize: 4. server waitForConnectionFor: 600. Client doit: server := Socket newTCP. server listenOn: 12345 backlogSize: 4. server waitForConnectionFor: 600. client := server accept. client receiveData. but the server just hung forever. After flopping around for a while, and checking the swiki, it seemed to be listenOn:backlogSize: that was the problem. Everything went well with: Server DoIt: server := Socket newTCP. server listenOn: 8080. server waitForConnectionFor: 600. server sendData: 'Hello from the server' Client PrintIt: client := Socket newTCP. client connectTo: (NetNameResolver localHostAddress) port: 8080. client receiveData. Anyway, I'd like to have this be clearer, but my knowledge is very basic. Also, the class comment for socket reads "...Sockets are the lowest level of networking object in Squeak and are not normally used directly..." so is this where we want to direct people first?

[Pharo-project] What are you using to write reports?
by Torsten Bergmann Sept. 1, 2010

>Well VBA and Excel is well working, I doubt that OpenOffice Basic can >compete with it. Yes, thats why I started to write a COM wrapper for Squeak in 2008 - unfortunately stopped due to missing time and missing callbacks in FFI. And Alien (providing callbacks) is still not available ... Using COM would open the whole windows world (from Office to SAP, ...) and by using CCW' and RCW's one could also use the .NET world. However - there was/is also a Squeak .NET bridge one can use. BTW: Did you look at Javas/Apache FOP? I know it is used by a few Seaside apps to create PDF's using XSL-FO. Bye T. -- Neu: GMX De-Mail - Einfach wie E-Mail, sicher wie ein Brief!

[Pharo-project] Serial ports on Linux
by Schwab,Wilhelm K Sept. 1, 2010

Sept. 1, 2010

I have been able to do serial I/O on Windows, but not Linux. Running in a terminal to capture output yields "Error while saving old state" while trying to open just about any number or name I can think of (including 0 and /dev/ttyS0), but the open method gives no indication that there is a problem; it returns a perfectly valid looking serial port with the #port set to whatever it was given. Subsequent reads fail, and are probably a bit more honest about what is happening: "Error while reading: serial port is not open." I am not sure whether that is always the case, but it certainly is on this machine when I try /dev/ttyUSB0, which does not exist here. Any ideas? Bill
