GrammarKit is a plugin by JetBrains for creating custom language plugins
for JetBrains IDEs (such as IntelliJ, RubyMine, CLion and more). It
defines a BNF parser language which can be used to generate a parser in
Java, and it also integrates JFLex for generating a lexer in Java.
Both of these generated Java files can be recognised by a comment on the
first line of the file, and so classifying them as generated is trivial.
This changeset includes a sample racc file from [this auto-generated
file](44e9bf0440/lib/rjson/parser.rb)
(MIT-licensed).
[Racc](https://github.com/tenderlove/racc) Racc is an LALR(1) parser
generator. It is written in Ruby itself, and generates ruby programs.
Minified JS files usually contain less than 2% spaces, while minified
CSS files may contain about 4% spaces. However, an unminified CSS file
may also have as low as 6% spaces, especially when it includes some
resources inline. Consequently, the division might not be appreciate
for CSS files. Even though, it will only mis-recognize a normal file
as minified for a few special cases.
