Re: [Pharo-users] SCouchDB install not working in Pharo: "MessageNotUnderstood: receiver of ""mantis"" is nil"
by pvdh＠vanderheyden.be Oct. 25, 2016

Oct. 25, 2016

Hi, I have tried to 'ConfigurationOfSCouchDB load' in Pharo 4 and 5. It seems to load an old configuration of Seaside and it ends up with an error: "No version found for #stable of ConfigurationOfOmniBrowser while loading Seaside" I don't understand why the ConfigurationOfSCouchDB depends on Seaside and why it refer to an old Seaside 3.0 version. Thank in advance for your help, Philippe

Final Project: AR.Drone communication API in Pharo
by Carolina HernÃ¡ndez Oct. 25, 2016

Oct. 25, 2016

Hi! Earlier this year I told you about the communication API for controlling the AR.Drone 2.0 from Pharo I was developing as part of my final degree project. Today I want to share with you its final version. As before, the code is hosted in: http://smalltalkhub.com/#!/~CaroHernandez/ArDronePharo I made two demo videos: http://bit.ly/ARDroneLRP1 http://bit.ly/ARDroneLRP2 In each demo the drone flies autonomously according to the location of tags detected by its cameras. The demos are programmed using a live programming language called LRP. This language was developed by members of my university. Here you can find more about LRP: https://pleiad.cl/research/software/lrp The code was tested and developed under ubuntu 12.04 and Pharo 5.0. I hope you like it! :-) Cheers Caro

[Pharo-dev][ANN] Scale
by Santiago Bragagnolo Oct. 24, 2016

Oct. 24, 2016

Hi everybody. We are officially releasing a first version of scale. Scale is a command line handler that is there for making easier the life of the people that uses scripting in linux. As such, we only tested it so far in linux. It will be for sure easy to adapt it to mac because its a *nix, but not for windoze. *IMPORTANT REMARK*: scale is not meant to develop applications, it is meant to develop scripts in Pharo, to be launched from the command line. This means that scale does not provide a top level syntax to declare classes or methods: people should do that as any normal Pharo application. Scale should be used to invoke such applications. When would you use scale? - For example, to replace some bash scripts used for common boring tasks (and you are using python or ruby there :P) - Another example, would be when you want to replace bash scripts that chain things like: ./pharo eval --save "something" ./pharo eval --save "other something" ... Github: https://github.com/guillep/Scale Oneliner to install: (note it needs sudo) wget -O- https://raw.githubusercontent.com/guillep/Scale/master/setupScale.sh | sudo bash In the repository there is some user level documentation based on examples and a list of available methods on the magical variable system. There are many examples as well on the repository. Last but not least, I'm using this project in others two projects, where it proof it self quite powerful what keeps me on maintaining Scale. These projects are: *Pharo Android VM building *https://github.com/sbragagnolo/pharo-vm Here I use it for automating the creation of a * new building image, * the creation of new resource image (for deploying on the android apk), * linking the android sources into the building directory * generating the code from the console *MakrosTool* https://github.com/sbragagnolo/MakrosTool MakrosTool is an extension of scale that adds a second magical variable for building up component reification in a ROS based environment.

What is the correct way to go around implementing a GUI feature in Pharo?
by CodeDmitry Oct. 23, 2016

Oct. 23, 2016

I want to have a bootstrap-like navbar at the top of my pharo GUI to store commonly accessed features/custom hierarchies of menus. My first thought is that I should spend a bunch of time playing with Morphs and invent my own MVC(models being the state managed by the menu, views being the controls(morphs), and controllers being asynchronous blocks of code that are invoked when events occur). Are there any good resources that teach how to go around doing stuff like this, or do I have to reinvent it myself by researching how Pharo GUI works internally, and figure out how to do this by successful incremental experiments? -- View this message in context: http://forum.world.st/What-is-the-correct-way-to-go-around-implementing-a-G… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
