Unfortunately, from my side this is only going to happen if I give the course to a group of youths that speak better English than German. But it might be possible to have a low effort translation using Google Translate. I just experimented and took a random instruction page from my course and sent it through Google Translate, and the result is remarkably good (see below). Moreover, all the code of the exercises is of course already in English rather than German. Anyway, here is what Google Translate gives for the German instruction block below the code block on https://github.com/jvoigtlaender/Elm-Kurs/blob/master/pages/Counter.md. Pretty good (though not completely accurate, it’s still just a machine translation): There are some things to explain: We have to express what the “remembered state” should be at the beginning, if there is no past to remember. Since we want to implement a simple counter here, we use the number 0 for this. We have to express how the state should change when an event occurs. This is done in the update function. It uses case … of … to make a case distinction on the event. Here, we will first react only to the event “Empty button was pressed” (space), in this case, increase the counter reading by 1. To express that in any other case (when the empty key has been pressed), we will use the line _ -> state. Such or similar lines should always exist in the following. In the scene function, the current state is now available as a further input and can be used to calculate the output (ie the display to be rendered). Here, we simply output the current counter reading directly. We ignore the current mouse position and time (also in the update function). By means of the displayWithState function, we bring everything together. Task: Change the above program so that the counter starts at 10, is increased by means of the arrow-up key and is reduced by means of the arrow-down-key, but never drops below 0. In addition, the empty button should now be able to set the counter to 0 at any time. (The left, up, right and down event names exist for the four arrow keys.) -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.
