TODO: Implement format list support.

C minus minus (Cmm) is a pun on the name C++. It’s an intermediate language of the Glasgow Haskell Compiler (GHC) that is very similar to C, but with many features missing and some special constructs.

Cmm is a dialect of C–. The goal of this lexer is to use what GHC produces and parses (Cmm); C– itself is not supported.

See www.cs.cmu.edu/afs/andrew/course/15/411/ghc/share/doc/ghc/ext-core/core.pdf for a description of the syntax of the language and www.aosabook.org/en/ghc.html for a high level overview.

TODO how are we going to handle soft/hard contrast?

Constants

LIB_DIR: cache value in a constant since ‘__dir__` allocates a new string on every call.

Public Class Methods

highlight(text, lexer, formatter, &b) click to toggle source

Highlight some text with a given lexer and formatter.

@example

Rouge.highlight('@foo = 1', 'ruby', 'html')
Rouge.highlight('var foo = 1;', 'js', 'terminal256')

# streaming - chunks become available as they are lexed
Rouge.highlight(large_string, 'ruby', 'html') do |chunk|
  $stdout.print chunk
end

# File lib/rouge.rb, line 28
def highlight(text, lexer, formatter, &b)
  lexer = Lexer.find(lexer) unless lexer.respond_to? :lex
  raise "unknown lexer #{lexer}" unless lexer

  formatter = Formatter.find(formatter) unless formatter.respond_to? :format
  raise "unknown formatter #{formatter}" unless formatter

  formatter.format(lexer.lex(text), &b)
end

load_file(path) click to toggle source

Load a file relative to the ‘lib/rouge` path.

@api private

# File lib/rouge.rb, line 41
def load_file(path)
  Kernel::load File.join(LIB_DIR, "rouge/#{path}.rb")
end

load_lexers() click to toggle source

Load the lexers in the ‘lib/rouge/lexers` directory.

@api private

# File lib/rouge.rb, line 48
def load_lexers
  # The trailing slash is necessary to avoid lexers being loaded multiple
  # times by `Lexers.load_lexer`
  lexer_dir = File.join(LIB_DIR, "rouge/lexers/")
  Dir.glob(File.join(lexer_dir, '*.rb')).each do |f|
    Lexers.load_lexer(f.sub(lexer_dir, ''))
  end
end

reload!() click to toggle source

# File lib/rouge.rb, line 13
def reload!
  Object::send :remove_const, :Rouge
  Kernel::load __FILE__
end

version() click to toggle source

# File lib/rouge/version.rb, line 4
def self.version
  "4.0.0"
end
