Thanks Phil! That's not easy to do now, Is mean to be a feature for the next version. By the moment you have to add the variable to SCScriptRunner and initialize the value maybe in initialize. This SCScriptRunner is the context of execution of the script.

[Ann] Stack Android VM

by Santiago Bragagnolo

Still far from production. But since i would happy to have some feedback, I'm happy to show you some progress on the android VM. Not yet release. But we have already a way of compiling and deploying an image into an android device. You can check it in this repo github. https://github.com/sbragagnolo/pharo-vm/ The building steps are detailed on the README-Android.md file. Building the Stack AndroidVM 1. Download the sources from github <https://github.com/sbragagnolo/pharo-vm> git clone --depth=1 https://github.com/sbragagnolo/pharo-vmcd pharo-vm 2. Set-up your environment: This script will download the SDK installer and NDK R10 cd android/scripts ./setupAndroidEnvironment.st This script downloads the content from - ' http://dl.google.com/android/repository/android-ndk-r10e-linux-x86_64.zip '. - 'http://dl.google.com/android/android-sdk_r24.4.1-linux.tgz'. After this process you should have available the environment variables ANDROID_NDK_HOME and ANDROID_SDK_HOME. Ensure this by checking your .bashrc file at the user's home directory. 3. Create a new image: this image will be created by pointing to this local git repository cd android/scripts ./newImage.st 4. Link sources to the build folder: The Android vm relies on a Java wrapper. This sources must be accessible from the build folder. cd android/scripts ./linkSources.st 5. Generate the sources of the stack vm: This script executes the generator of the image created on int the 3rd step. cd android/scripts ./generateStackAndroidMake.st 6. Generate the resource image for deployment: This script download and suites up an image for deployment on the folder build/assets/SmalltalkRessources cd android/scripts ./newResourceImage.st This image created in this point is downloaded with it related VM for editing and loading the code you want to deploy, or configure the things you want. 7. The VM compilation: This script generates the libraries with the VM code. cd build ./build.sh 8. The Java wrapper compilation and Android Application packaging cd build ./package.sh 9. Installing into your device. If you want to generate an APK file with your custom name, you will need to deal with the AndroidManifest.xml before runing the package.sh script :) cd build/bin adb install -r StackActivity-debug.apk - Im currently working on the JIT version of the VM, that still avoiding me :). But you have as well the instruction on the same README-Android.me file. Santiago

[ANN] Scale

by Santiago Bragagnolo

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.

I use the Printf package for that. v := 65.456. 'With 2 decimal digits: %5.2f, or 3 like this: %6.3f' printf: {v. v}. With 2 decimal digits: 65.45, or 3 like this: 65.456 It is in http://www.smalltalkhub.com/#!/~philippeback/HOExtras Printf I am just used to C printf and well, I like the way it works.
