Creating custom formatter for Java

1. google-java-format

   1 25 5,770 8.3 Java

   Reformats Java source code to comply with Google Java Style.

   

   I spent most of my development career writing simple CRUD applications, recently I read a fascinating article: http://journal.stuffwithstuff.com/2015/09/08/the-hardest-program-ive-ever-written/. It looks like a nice challenge to try creating such a tool. For sure I need first to understand how to build AST etc. I could reuse existing solutions like https://github.com/google/google-java-format, or eclipse fmt, but I would like to understand the whole process, to be able to debug all cases.

   Grammars written for ANTLR v4; expectation that the grammars are free of actions.

   

   Initially, I was thinking about learning ANT and using it, but I see that they provided grammars for: java8 and java9 https://github.com/antlr/grammars-v4/tree/master/java

   Check out the source code for JavaDoc to see how JavaDoc does AST generation and processing, since uses the AST to generate the HTML documentation.
