A remote workspace
Locked
 
|
Hello,
Following the discussion on VM remote administration ( http://lists.gforge.inria.fr/pipermail/pharo-users/2010-May/000268.html ), I started working on something like a remote workspace. So far, I'm able to connect to a VM running Pharo with netcat, and execute some code. It is not much, but it was fun to write, and I learned a lot of things :) Now, before I add new features, I feel I should ask if someone would be interested by this, and what use case you would imagine: -Connecting from another VM or sticking with netcat? -Remote debugging (might not be easy, but should be fun to do) -Sending commands to a lot of VMs at once (and querying status) -Multiple connections possibles? -Being able to save a session (like http://www.gnu.org/software/screen/ ) -Authentication/encryption? Is there a way to use openssl, or should I steal the 3DES code from RFB (it should be quick enough for text only communication)? Best regards, Geoffroy _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

Hi Geoffroy! This sounds extremely cool. My little advice is try to concentrate in performance. I mean, you can have all the features you want, but if you have to wait 5 seconds for each character you type, then it will not make sense. So, from my point of view, is to get an acceptable performance writing in the workspace. After that, you can add features.
Just my opinion. Hope you continue with this work.

There's a package called REPLServer for Squeak which does the above. It has command line editing and history. It doesn't have a debugger yet. I use it to "reboot" Morphic to get back to a debugger after a bad crash. Nor does it have session management, but that could be added easily. I never thought of doing that. REPLServer just uses telnet and only listens to localhost. I figured that if anybody wants to do secure stuff, then they could SSH into the remote host and then use telnet from the command line to get to Squeak.

Well, for now, there is no problem with performance, because the command is sent only when I hit enter, and the result is returned immediatly after execution. But completion could be added. _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

You are a godsend! I was just asking about this feature on the list...
1) Should be reasonably fast 2) Should use secure connection (ideally ssh). I'd rather teach Pharo communicate via standard input/output first so you can use it as a command line tool, then expand this ability to talk via any variant of TCP/IP. I am very new to Pharo so I don't know the extent it's married to its GUI environment, not sure how easy it is to implement...

Don't be sad, maybe you could port (and adapt) the REPLServer to Pharo and put it on SqueakSource in order to load it in the image very easily. It's already a lot of work and it might interested a lot of people in the Pharo community.

Hello,
Here is a Metacello configuration for REPL: http://eleves.ec-lille.fr/~couprieg/divers/ConfigurationOfREPL-GeoffroyCouprie.3.mcz Is it OK?

cool cool cool
Geoffroy two things if you have access rights to the squeaksource project it would be nice to publish it there then in addition it would be nice to publish it in the MetacelloRepository repository. stef On May 15, 2010, at 5:08 PM, Geoffroy Couprie wrote: > Hello, > > Here is a Metacello configuration for REPL: > http://eleves.ec-lille.fr/~couprieg/divers/ConfigurationOfREPL-GeoffroyCouprie.3.mcz > > Is it OK? > > On Thu, May 13, 2010 at 1:51 PM, Stéphane Ducasse > <[hidden email]> wrote: >> yes >> >> http://gemstonesoup.wordpress.com/2009/10/19/metacello-tutorial-updated/ >> >> >>>>>> >>> >>> I tried REPLServer, and it works really well! >>> >>> It has a dependency on TcpService, so I had to install KomServices and >>> DynamicBindings.

Cool. Can someone write about the various way to access Pharo remotely with pro/cons in the Pharo collaborator book ?
