JSON is one of the most common data interchange formats: a human-readable way of exchanging structured data that is ubiquitous throughout industry.
Scalatags renders HTML templates, which are often written to files using OS-Lib, or served to a browser via a Cask server uPickle generates JSON and MessagePack blobs, which are written to files using OS-Lib, served to a browser via a Cask HTTP server, or uploaded to a server via Requests-Scala The Iterator.continually approach lets you loop over each byte in the file. I've so long lived with the strong belief that Spark API for Scala was always the most feature-rich and your question helped me to learn it should not have been so before the change in 2.3.0 (!) Naming variables after what they contain is a good practice that should be followed.
If you use single quotes (`) to escape the @ symbol your IDE will likely not give you any errors, but it will probably throw a runtime error. JochemQuery It is up to you, of course, but I would leave it on. samples: To see generated code for codecs add the following line to your sbt build file:Samples for integration with different web frameworks:For all dependent projects it is recommended to use So if your system is sensitive for that and can accept untrusted input then avoid parsing with The workaround is to move a definition of the field with encoded chars (But sometime scalac (or zinc) can fail to compile the Workaround is the same for both cases: don't enclose ADT definitions into outer The workaround is to split sources for JVM and JS and use Java enum emulation for JS.A workaround is using the following configuration for the compiler to produce ES 5.1 output:Before benchmark running check if your CPU works in Sbt plugin for JMH tool is used for benchmarking, to see all their features and options please check If he uses 'data' for his field, then he might iterate over it later in the code and someone looking in will not know what "data" represents. @Jochem third party links are frowned upon, due to their dynamic nature (someone may click the link in the future and won't find anything helpful). Is there an exception? When the end of file is reached a -1 value is returned by the read method, so that’s why the takeWhile method is used as shown.. I wrote a really basic benchmark of it and most of the time, it was about 5% faster for large files (test was ~35 MB text file) all the way up to 2,800% faster for small files (test was ~30 KB). The library targets JDK 8+ and GraalVM 19+ (including compilation to native images) without any platform restrictions.Support of Scala Native is not a goal for the moment.There are configurable options that can be set in compile-time:List of options that change parsing and serialization in runtime:Let's assume that you have the following data structures:Add the core library with a "compile" scope and the macros library with "compile-internal" or "provided" scopes to your I'm rereading my code and trying again@Ads Done, Am I missing "correct" getters and setters?

Does that code compile? What does the JSON look like? – Colin Dean Nov 6 '15 at 19:31 are required):Do not push changes to GitHub until promoted artifacts for the new version are not available for downloading on Play JSON is a powerful Scala JSON library, originally developed by the Play team for use with Play Framework. This tutorial will walk you through how to work effectively with JSON data in Scala, walking through a few common workflows on a piece of real-world JSON … Stack Overflow for Teams is a private, secure spot for you and
all new for me, currently testing and debugging everythingThanks for the explanation @DaveLugg and the answer -Ads. This is potentially an order of magnitude faster than scala.io.Source in Scala 2.11.7. Featured on Meta
Scala macros that generate codecs for case classes, standard types, and collections to get maximum performance of JSON Discussion. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Unfortunately, Scala being the finicky beast that it is, you can’t use an @ symbol as the beginning of a key name in a JSON object. Your question helped me to find that the variant of from_json with String-based schema was only available in Java and has recently been added to Spark API for Scala in the upcoming 2.3.0.
