for line wrapping and indentation) can be found in .formatter.DefaultCodeFormatterOptions. Unfortunately, there seems to be no documentation, so you have to look into the source code of .formatter.DefaultCodeFormatterConstants to see the available settings. At the moment, the entries are ordered lexicographically, which makes it much easier to find similar keys and also to compare diffs with git. Please do not just load the file into Eclipse, adapt it and export it again, as this will completely reshuffle the entry lines. The config file for the KeY style is located in key/scripts/tools/checkstyle/ke圜odeStyle.xml. ** Warning: This will affect the whole code base! Only change if you are sure! ** Configuring the formatter options for Java (Eclipse formatter) ¶ It is a version of the Google Java Style adapted to our code conventions. The configuration is provided as an XML file and can be found in scripts/tools/checkstyle/ke圜odeStyle.xml. Spotless supports several formatters, for Java files we currently use the Eclipse formatter, since it provides the most options of the available formatters and thus allows us to configure the automatic formatting in a way that it conforms to the KeY code style ( ). Note that there are separate tasks of the form spotlessCheck/Apply for every defined format, e.g. It is also possible via spotlessApply to just apply the changes and write them back. The task spotlessCheck does not change the actual files on disk. Note that due to this nature of the check, spotless is not able to give any detailed information about the rule that is violated. g4 (ANTLR grammars) How Spotless works ¶īasically, for every format/file type defined in the config file, the task spotlessCheck applies the defined function(s) to every file of this format and then checks if the result is equal to the original file. Return new BigInteger(s, 16).Automatically formatting code with Spotless ¶Īs a step towards a consistent code style in our code base, we automatically formatted our code with spotless.Ĭurrently, we apply spotless to files with the following extensions: Return String.format(“%040x”, new BigInteger(1, arg.getBytes(faultCharset()))) String binary = hexToBinary(hex) // converts Hexadecimal string to binary format String hex = toHex(str) // converts String to hexadecimal format If you wish to convert text strings to binary then you can use the below mentioned code: String text = Integer.toBinaryString(ch) // converts ASCII value to Binary If you want to find the binary of a singular alphabet, then you can make use of Ascii codes as given below: This Base64 encode decode string is still widely use in decode, convert base64 encoded string back to byteīyte decode = Base64.getDecoder().decode(s) String s = Base64.getEncoder().encodeToString(bytes) encode, convert byte to base64 encoded string However, for cases that byte is holding the binary data like the image or other non-text data, the best practice is to convert the byte into a Base64 encoded string.īyte bytes = Files.readAllBytes(Paths.get("/path/image.png")) Convert byte to String (binary data)įor text or character data, we use new String(bytes, StandardCharsets.UTF_8) to convert the byte to a String directly. String s = new String(bytes, StandardCharsets.UTF_8) In Java, we can use new String(bytes, StandardCharsets.UTF_8) to convert a byte to a String.īyte bytes = "hello".getBytes(StandardCharsets.UTF_8)
