destructDo:
by Christian Haider March 30, 2020

March 30, 2020

Hi, I am using a nice little method #destructDo: for a while now and it feels good. In VisualWorks: SequenceableCollection>>destructDo: aBlock "Evaluate aBlock with the receiver's elements as parameters. aBlock takes its arguments from the receiver. 'ok' #(1 2 3) destructDo: [:a :b :c | a + b + c] #(1 2 3) destructDo: [:a :b | a + b] #(1 2 3) destructDo: [:a | a] #(1 2 3) destructDo: [42] 'not ok' #(1 2 3) destructDo: [:a :b :c :d | a + b + c + d] " ^aBlock cullWithArguments: self asArray In Amber: SequenceableCollection>>destructDo: aBlock ^aBlock valueWithPossibleArguments: self In Pharo and other dialects, I don't know, but should be as easy. For example you can do (('2020-03-28' tokensBasedOn: $-) collect: #asNumber) destructDo: [:year :month :day | Date newDay: day monthNumber: month year: year] I like that the block is not the receiver (like with #valueWithArguments or #cullWithArguments), but the last argument. Now the questions: * I am sure that others came up with this. Anybody knows? * What are you using for this pattern? * I don't really like the name, but haven't found anything better yet. Maybe #destructedDo: or just #destructed: or: #withPartsDo:. maybe something shorter? Ideas? * What are you thinking about this? Happy hacking, Christian

[ANN] CoViD-19 Charts prototype
by Christian Haider March 20, 2020

March 20, 2020

Hi all, the corona virus is a bummer and it keeps me occupied more than is good for me, I guess. Since I am unhappy with some infos on the web (some are really nice!), because I want to see different numbers and charts. So, I used the opportunity to try out Amber for real. Here it is: https://covidcrt.uber.space It is still bare and simple, but here I can get a better picture of the development of this crisis. Especially, I wanted to see how the case increases develops (how fast is the increase increasing). I look at Italy, Germany and especially, the US. This is scary! >From today until Sunday, there will be a virtual hackaton from the German government [1]. I want to participate and will work on this. Anybody interested? You can apply until 14 o'clock GMT. (And yes, I know that it is stupid that Germany does it on its own, but better than nothing!). Technicalities (for people who want to play with the source): Everything is open and under MIT licence. 1. There is a small VisualWorks program loading the data from the John-Hopkins-University, transforming them and saving the data as JSON. The package is [CoViD19] in the public store. 2. The app is in Amber Smalltalk and the html is done with Silk. Silk is very exciting and makes web programming fun again. I am completely enthusiastic about it :-) ! Unfortunately, setting up the development environment is a bit complicated, because I issued a pull request[2] for an addition to Silk which is not incorporated yet. Therefore, after you did all the normal setup, you need to replace the Silk source files in ./node_modules\@ambers\silk\src with the files in [3]. Also, I disabled my dev buttons in the app. To open Helios, the browser, you have to enter require('amber/helpers').popupHelios() in the browser console of the dev tools. Happy hacking and good luck to everybody, Christian [1] https://wirvsvirushackathon.org/ [2] https://lolg.it/herby/silk/pulls/11 [3] https://covidcrt.uber.space/Silk.zip
