Re: [Pharo-users] XML Writer not pretty printing

Thanks! #removeAllFormattingNodes did the trick. Perhaps #prettyPrinted / #enablePrettyPrinting should call it by default?

Tutorial files placed on Github are notebooks written on jupyter using JupyterTalk Kernel. They are not an installation procedure. I have just ran it in a new linux machine an now it works also on linux. I have done using pharo-launcher on a 64 bits image. - kernel description file must be placed in "/usr/local/share/jupyter/kernels/Pharo" as you can see in the screenshot. Take a look to the kernel.json file, you have to create this file and save it in "/usr/local/share/jupyter/kernels/Pharo". <http://forum.world.st/file/t369275/Captura_de_pantalla_2018-08-15_a_las_20.…> - ZeroMQ module name is libzmq.so.3 almost in my ubuntu linux after jupyter installation. I have updated github repo, so now it is working also on linux. Try again, let me know if it's working for you. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

First screenshot shows a warning because JupyterTalk script doesn't care about if Roassal or Polymath are installed or not, only tries to add some methods to several of its classes...for sure you will be interested in these frameworks combined with Jupyter, I suggest you to install them before JupyterTalk. If you are not planning to work with them, you just have to press "PROCEED" button. The error in the second screenshot is because JupyterTalk has to free the ZeroMQ context before closing the Pharo Image but It can not find the library...did you install Jupyter and ZeroMQ in your system? I have only tested on Mac Os X...There is a package called ZeroMQ , find LibZeroMQ class and check the unix64ModuleName and unixModuleName, it returns 'libzmq.so' but sure this is not the correct name!. Look for the correct module name in your system and test this package (this could hang the image, save it before) The last thing is to configure Jupyter for the new kernel. You need to find the correct path for the kernel configuration files. In Mac Os is "/usr/local/share/jupyter/kernels", you have to create a new folder inside named "pharo" containing a configuration file named "kernel.json" like this. '{ "argv": [ "/Path/to/Paro/executable/Pharo", "/Path/to/Pharo/Image/File/Pharo6.1-64.image", "ipharo", "{connection_file}" ], "display_name": "Pharo Smalltalk", "language": "smalltalk" }' Optionally, in the same folder you can place an image named "logo-64x64.png" with a Pharo logo so you will see the logo left to the logout button. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

To clarify my question: I read the tutorial http://htmlpreview.github.io/?https://github.com/jmari/JupyterTalk/blob/mas… My question is: How do I start JupyterTalk and how to I connect then to the Pharo Smalltalk kernelt from an nteract (https://nteract.io/desktop) client HH On 8/15/18, H.

After loading Roassal2 through the Pharo 6.1 catalog and re-executing the Metacello load script Metacello new baseline: 'JupyterTalk'; repository: 'github://jmari/JupyterTalk:master/repository'; load:'all' All loaded fine. I found 2 tests. (Result attached). One of them fails. The question is now how to proceed. On https://github.com/jmari/JupyterTalk/blob/master/README.md writing the installation procedure is noted on the 'ToDo' list. I suggest that we just develop the procedure in this mail thread. Most important question now is: How do I start the Pharo Smalltalk Jupyter kernel? HH. On 8/15/18, H.

You already have all the information you need. RT classes missing. Is this supposed to be run in Moose only? Stephan
