But the "set SSH_AGENT_PID=...." is done because the cmd.exe launched by ProcessWrapper does not detect SSH variables from other environment/term. I think many platforms (MinGW/MSYS/Cygwin) use something like this to launch ssh-agent for every term: echo "#!/bin/bash \ eval `ssh-agent -s` \ ssh-add" >> ~/.bashrc > In any case I have notes about the implementation: > > 1. it assumes that it runs only on windows (it looks like this should be > generic code) > 2. it assumes that ssh-agent will be always installed in a specific path, > it should rely on PATH instead > Yes, some time ago I sent some FileSystem extensions to locate path binaries.

Pharo messaging

by Torsten Bergmann

Hi, Lots of message apps in use today (WhatsApp, Telegram, ...) on phones and mobile devices. There is "WhatsAPI" [1] - but my understanding is that it was closed for legal/security reasons. There are other solutions like Telegram that also have an API [2]. What options do we have in Pharo these days: - to send messages from Pharo to a phone - receive messages from an app to control a Pharo image remotely from a phone or communicate Thanks T. [1] https://github.com/venomous0x/WhatsAPI [2] https://core.telegram.org/

Nice. We'll be able to improve our development flow a lot by reducing synchronization delay. Stephan

I just took a quick look. It depends on both LayeredProtocol and SSL, but SSL won't load as HierarchicalUrl is missing. thanks, Robert On 10/13/2015 04:02 AM, Thierry Goubier wrote: > > > 2015-10-13 9:46 GMT+02:00 Robert Withers <robert.w.withers(a)gmail.com > <mailto:robert.w.withers@gmail.com>>: > > Would the SSH package in Cryptography help you? > > > I don't know.

Thanks! > I was setting up ssh-agent under windows couple years ago so I don't quite remember what was the problem exactly, but iirc the problem was that ssh-agent was setting the variables only locally (maybe because it didn't understand windows env system). So the way I forced it to work was that I manually created a permanent record for SSH_AUTH_SOCK with some predefined path, and then I was starting the agent with "ssh-agent -a "$Env:SSH_AUTH_SOCK" this way the agent was bound the the socket specified by the global variable. Git itself was then able to correctly read the value from the environment, so I didn't have to change anything for git, it worked out of the box (as long as the env was correct). Interestingly I never needed SSH_AGENT_PID, but maybe git just needs the socket. Peter

Re: [Pharo-users] [Pharo-dev] binary serialization

Sven and Torsten, that's a binary serialization library! It will take time to learn it and how to use mappers. What is the format; is it language neutral? thanks, Robert On 10/13/2015 01:21 AM, Sven Van Caekenberghe wrote: > Yes, it is called FUEL and it is a standard part of the image.

In any case I have notes about the implementation: 1. it assumes that it runs only on windows (it looks like this should be generic code) 2. it assumes that ssh-agent will be always installed in a specific path, it should rely on PATH instead 3: Windows has its own system for global env variables, so why not use that?
