Hash values
by Alexandre Bergel Sept. 26, 2014

Sept. 26, 2014

Hi! Alejandro and I are working on a new profiling technique to identify redundant objects. Weâve heard there are some effort on increasing the range of identity hash values. Currently, it goes up to 4096, which is not much. Can someone tell us about this? Also, I discovered that -100 hash = -100. Does this make sense?

Passed by references and by value
by nacho Sept. 26, 2014

Sept. 26, 2014

Hi, In PBE says that ordinary objects' ivars are passed by references and small integers are passed by value. Is there a way to know if a class is passed by reference or by value? Only small integers are passed as value? Thanks in advance Nacho ----- Nacho Smalltalker apprentice.

Re: [Pharo-users] invoking python from pharo

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.

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.

Loading PetitParser loads a hell of a lot of things... is there a terser version?

Sept. 25, 2014

I am loading PetitParser in my image but it takes a loooong time to load and below is what I see in my Jenkins console. Build for that step starts at 13:48:51 and ends at 14:03:15. Phew! Also a couple errors in loading examples. What is recommended to use to not have all of this? I just need the parser and tools to browse the grammars.

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.

Not much of a script as such. Put your Pharo image, changes and sources files in your home directory. create/edit a file called .xinitrc containing only "exec pharo-vm-x" (without quotes) within your home directory. Start the X session by issuing "startx" at the command line, and the GUI should be up with Pharo as the only application, no need for even a window manager. Next, just set the Pharo session to use full-screen mode by bringing up the "World" menu inside Pharo, go to the "Windows" sub-menu, and choose "Toggle Full Screen mode", and voila, you have a Pharo full-screen session, as if it's your GUI, remember to save the changes when you quit the Pharo session (which will drop you back to your *nix shell). The next time you issue "startx" within your home directory, the GUI presented would be Pharo. :) Still working on making Pharo the only shell running directly atop the Linux kernel with X as the windowing system, yeah, tried Linux FB, failed.

Gettext with pharo 3 and seaside 3.1.2
by Peter Schorsch Sept. 25, 2014

Sept. 25, 2014

Hi, Just started with pharo and seaside. Now I want to write an example seaside-application but with a multi lingual interface. So I installed pharo3 and then seaside via configuration browser. But then I had to realize that the seaside-gettext package was not installed; and also no gettext package. I found a gettext package in the repository http://smalltalkhub.com/mc/PharoExtras/Gettext. I installed the package ConfigurationOfGettext, but the configuraitonof-browser does not show it. So I installed the package Gettext via monticello. Then I found the seaside-gettext packages in the repository http://smalltalkhub.com/mc/Seaside/Seaside30Addons and installed via monticello the packages Seaside-Gettext-Core and Seaside-Gettext-Examples. Then I open a webbrowser to watch the gettext example. But there I only see: fontsize * locale * locale * locale * locale * locale That looks for me like gettext is not working with pharo3 and seaside 3.1.2 Any help is welcome - best a mini howto for gettext with pharo3 and seaside 3.1.2 Thanks in advance
