People are starting to use Machine Learning to write better code.
One example is code formatting. Instead of painstakingly writing a parser and then rules which are to be applied to each node of the Abstract Syntax Tree (AST), the guys from Codebuff are using the “learn by example approach”. Just feed Codebuff with a couple of examples and it will learn to apply those implied rules to source code.
If you find something that looks bad, you don’t have to dig through dozens of pages of code formatter options or code formatter config files, just add more examples.
If you’re using Xtext, you can use the tool to write code formatters for you DSL: “Machine Learning Formatting with Xtext“
