Its far from excellent. Its not as tested as I want it to be, and the code could be much better but it works and makes interfacing with python code very easy.
Its also an ongoing project that I will keep adding feature to , for example I would like to extend pharo syntax to more complex stuff than calling python methods like defining python classes etc so you wont have to use sendMessage and getValue at all and not have to write a line of python code. In short do all your python coding using 100% pharo syntax. But that will take a lot of time to do because it will require a fully python syntax parser. I have updated the code to resolve the error when issuing a command to close the bridge with Ephestos sendMessage:'exit'. This command basically terminate pyAtlas and closes it server socket. I dont know if its Pharo or Python or Macos but it looks like it takes time to free up the socket address so you will need 20 seconds to restart pyAtlas again. I tried to set the timeout of the socket to 1 second but it looks to me it still uses the default 20 seconds timeout. I guess 20 sec is not that bad for a pre alpha software :D But anyway that should not be a problem since you will have to rerun pyatlas every 20 sec , which is something you would not want to do . I was actually planning to test Ephestos with pyQT and pyCuda and make a youtube video about it but have not found the time yet. Probably in the weekend. On Thu, Sep 25, 2014 at 9:23 PM, Pablo R.
