Kawa | Scheme language , the Kawa framework | Bytecode library

I have problem with my code, I'm not able to save newline using binary port, I want to write unit test for my Scheme implementation but I'm not able to figure out why I got this results also in Gambit and Kawa (Gauche and Guile fail to run the code, because of missing procedures).

I am trying to get this html, but there is no class name. How could I do that?

That is my code in R:

I've written Scheme REPL that works in all implementations I've tested, but have problem when when someone press enter and don't type anything.

I'm playing with Scheme I want to run something like this:

I have Scheme interpreter in JavaScript called LIPS. I have executable file, it works in terminal emulator but it's broken in GNU Emacs inferior mode (using run-scheme function).

I've reproduced the issue with this simple Node.js REPL using Readline:

I have one more questions about Hygienic macros in Scheme, consider example from R5RS

I want to perform operations on a list of characters in R as describe below:

1. Keep only what is after the '-'
2. Then keep only the four first characters of the remaining (complete by 'J' if its length is lower than four)
3. Put everything in upper case

Example in Python

I am trying to wait after each for loop using Threads in my application but I have a problem. This for loop has to be executed when the film from URL is playing but...

Unfortunately the loop is executed with pauses that I put into the code and later the film starts with text updated. This should start simultaneously. The for loop and the film. During the film the texts should be updated one after another.

NOTE: I shorted the ArrayList dict to make code easier to understand.

NOTE2: The app tries to open video file from URL but it gives me a message: W/MediaPlayer: Couldn't open (Video URL) : java.io.FileNotFoundException: No content provider: (Video URL).

EDIT: I am putting an entire class code for you.

Recently I had problems with AAPT2. The problems were caused by my username that contained non-ascii characters. I created another Windows account(without non-ascii characters) and installed Android Studio on it. Then I opened my older project and when AS asked me to update I agreed to that. Now when I try to build my app I get these errors:

Android resource linking failed D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-v28\values-v28.xml:7: error: resource android:attr/dialogCornerRadius not found. D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-v28\values-v28.xml:11: error: resource android:attr/dialogCornerRadius not found.

D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:2971: error: resource android:attr/ttcIndex not found. error: failed linking references.

Most of threads I found of StackOverflow suggest that this problem might be related to support library, they say that version of it might be wrong. How could I change the version? My project also uses OpenCV library and configuration of it might be invalid. What I tried already was cleaning and rebuilding project and adjusting compileSDKVersion in Gradle.

Here is values-v28.xml file
