Well, maybe partially. At least "OSProcess isWindows" or "OSProcess osVersion" report the correct info.

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. Gulik. -- http://gulik.pbwiki.com/

Re: [Pharo-project] A remote workspace

by Mariano Martinez Peck

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.

[Pharo-project] A remote workspace

by Geoffroy Couprie

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

Hi. I have the following error: 'You have reached the size limit of the changes file. You must take action now to reduce it. Close this error. Do not attempt to proceed.' I know this is a known error, but I thought that with Igor's new method trailer this was fixed. Tested in 11355 Thanks Mariano

Now we want the same. Some of the above packages not even have tests or have failing/error. Some of them, not even load in Pharo 1.1 because of the underscore assignment.
