Asunto: Re: [Pharo-users] invoking python from pharo 

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.

Yes , I was aware of the excellent work of kilon. 
I was hoping that this be the way to solve my issue. 

Thanks kilon, I will follow your instructions and comment the results into the 
list.

Asunto: Re: [Pharo-users] invoking python from pharo 

a minor correction to the previous email its 
python3 pyatlas.py and not python3 pyAtlas.py 

also I forgot to make clear that it works for pyhton 2.7 and python 3.

Hi there, I promised to do this a long time ago, but since you asked it I done 
it now. 
So as Ben said I am the author of Ephestos, a communication bridge between 
Blender and Pharo . 

To go directly to the how to . Ephestos is basically a socket bridge that send 
via sockets strings from pharo to python that then python executes as python 
commands. 

Ephestos is made so it works inside blender but I promised Atals a spin off 
project that allows the same socket bridge to be used as a standalone. To use 
do the following. 

1) Get Ephestos , you can find it and install it with the configuration browser 
in your image in Pharo 3 and Pharo 4. Make sure you have a recent release 
though because I added it recently. 

2) Get pyAtlas , this is the python side , you can get it from here --> 
https://github.com/kilon/pyAtlas 

3) in your command line cd to the pyAtlas directory and execute : python3 
pyAtlas.py 

4) in Pharo you can now try any python code you want 

for example 

Ephestos sendMessage: 'print("hello world")'. 
Ephestos sendMessage: 'x = 3'. 
x := Ephestos getValue: 'x'. 
x inspect. 

Ephestos sendMessage: string, basically sends the python command to be executes 
while getValue: sends the command and returns a value as a string. 

you can use string 'exit' to close the socket bridge but this part is buggy as 
it seems to keep the binding of the sokcet active and I have to wait to clean 
it up in macos to reopen the bridge. 

You can also use pharo syntax and python errors will trigger the pharo debugger 
with a title the python error itself. 

You can find more information about Ephestos in my gitbook that can be read 
here 

https://www.gitbook.io/book/kilon/ephestos 

Also I forgot to add that sendMessage can send multiline strings , so its 
possible to send python class definitions and other stuff, you type the string 
exactly as you would type python code respecting whitespaces. If you want to 
execute loads of lines of python code then it would be better to put your code 
in a python module and do 

Ephestos sendMessage: 'import mymodule' 

assuming your module is called 'mymodule' , python import basically are 
executions of code. 

If you have any questions just ask. 

Bare in mind this is a socket bridge so its not ideal for sending thousands of 
messages per second and you may run into the occasional bug or two which I will 
fix if you report it. Nonetheless it should allow you to execute any kind of 
code and not just call python functions or python methods.

Hi all , I need to invoke python rutines from Pharo. I need some orientation 
about the best way to do it. 
TIA
