Hi nick I wanted to support your chapters via paypal but it asked me about my visa and I would like to pay via my paypal account. Do you know if this is possible? Else can you send me your pp account?

Roassal examples in playground in Pharo 7

by Cris Fuhrman

I'm trying to view the playground of an Example in Roassal in Moose 7 in Pharo 7, but I get the following error: Instance of RBSequenceNode did not understand #formattedCodeWithMaxLineLength: Using spotter I found that there's a method: #formattedCode, and substituting that with the debugger allows the example to show its playground. Should this "bug" (my interpretation) be committed to a tracker somewhere? Could this be a good candidate for the Pharo 7 deprecation re-writing feature? Cheers, Cris

Final Reminder: Only 5 spots left for Camp Smalltalk! Raspberry PI kits to all who attend!

by Mariano Martinez Peck

Hello All, There are 5 slots left for Camp Smalltalk Charlotte 2019 taking place at the end of this month. Now is the time to sign up if you are thinking of attending (see bottom for registration link). Camp Smalltalk is about community engagement and collaboration. There are a number of fantastic talks already lined up such as: Developing Smalltalk solutions running directly on ios / android mobile platforms (along with tooling) Live demo of @1MB remote-debuggable smalltalk images controlling peripherals attached to a Raspberry PI (ARM) In-depth look at large scale use of CMake/CTest/CDash for use with Smalltalk systems Smalltalk dialect portability solutions for the Smalltalk community (for use with GIT) We also have a fantastic Saturday evening social dinner planned on the boardwalk near the hotel. *As a special gift to attendees*, Instantiations will be providing everyone with their own Raspberry PI Zero Wifi devices with 8GB mini-sd card and power supply. Raspbian Linux with VA Smalltalk for ARM will be pre-installed. And if that isn't enough, each attendee will be receiving an open-source license for VA Smalltalk. This event is happening *March 29th – March 31st 2019* in Charlotte, North Carolina. Event details and registration info are available at the following link: Camp Smalltalk Charlotte 2019 <https://www.eventbrite.com/e/camp-smalltalk-charlotte-2019-tickets-52380940…> Hope to see you there!

anything like matplotlib/gnuplot interactive graphing?

by rsykora＠disroot.org

Dear list, I am checking what Roassal can do and was wondering if I could use it for quick data analysis, e.g., to draw a simple xy-data graph from a file and play around interactively with that, with the possibility to zoom / zoom back, switch easily to logarithmic axes, etc. So far I see RTGrapher, but as far as I can tell, no usable zooming functionality exists. Is there anything better? Thanks for any comments Ruda

using GT Releaser for handling Moose?

by Tudor Girba

Hi, Andrei wrote a post describing GT Releaser: https://medium.com/feenk/continuous-delivery-with-gt-releaser-4fc6c30e1f33 We use it for releasing reliably GT. GT is spread throughout multiple repositories and have deep dependencies, and yet we release it on every commit in a reliable fashion, while still allowing people to load small pieces independently from the overall GT. For example, people can load GT Examples, or GT Releaser independently. Another thing is that we also handle the dependencies to external projects, such as SmaCC. The same can be applied for Moose. Would you like to look into this opportunities to make Moose more modular and friendlier to outside projects? Cheers, Doru -- www.feenk.com "No matter how many recipes we know, we still value a chef."

Playing with PPHighlighter + inspector extensions

by Julien

I am able to do that: Changing node selected on the left updates the selection interval on the right. Highlighter is generated automatically from my PPCompositeParser. One step further to get good integration of PostgreSQL source code into Pharo environment. Next step is to have a code editor for PostgreSQL source code (really close to have it).

MSE interchange of custom properties

by Peter Uhnak

Hi, is it possible to interchange custom properties via MSE? e.g. I have added myProp to the method: ~~~~ ( (FAMIX.Class (id: 1) (name 'MyClass')) (FAMIX.Method (id: 2) (name 'myMethod') (myProp 'someValue') (parentType (ref: 1)))) ~~~ This is imported fine ~~~ s := Clipboard clipboardText asString. model := MooseModel importFromMSEStream: s readStream. model allMethods first propertyNamed: 'myProp'. "'someValue'" ~~~ However 1) I cannot see it in the Properties tab of the Moose Inspector, 2) when I export it, it is lost (instead some other properties are exported that I didn't ask for) ~~~ model asMSEString. "'( (FAMIX.Class (id: 1) (name ''MyClass'')) (FAMIX.Method (id: 2) (name ''myMethod'') (cyclomaticComplexity -1) (numberOfConditionals -1) (numberOfLinesOfCode -1) (numberOfStatements -1) (parentType (ref: 1)) (timeStamp '''')))'" ~~~ The same thing applies when I add custom Metanool annotation in the Meta edit tab... e.g. I add `an AnonymousClass[String]` with name `anotherProp` and some value, I can actually see it in the `Properties` tab (unlike the one imported), but when exported, it is also missing. Do I need to do some extra steps in order to interchange this information? Thanks, Peter
