# Wrapper for the Pygments command line tool, pygmentize.
#
# Pygments: http://pygments.org/
#
# Assumes pygmentize is in the path. If not, set its location
# with Albino.bin = '/path/to/pygmentize'
#
# Use like so:
#
# @syntaxer = Albino.new('/some/file.rb', :ruby)
# puts @syntaxer.colorize
#
# This'll print out an HTMLized, Ruby-highlighted version
# of '/some/file.rb'.
#
# To use another formatter, pass it as the third argument:
#
# @syntaxer = Albino.new('/some/file.rb', :ruby, :bbcode)
# puts @syntaxer.colorize
#
# You can also use the #colorize class method:
#
# puts Albino.colorize('/some/file.rb', :ruby)
#
# Another also: you get a #to_s, for somewhat nicer use in Rails views.
#
# ... helper file ...
# def highlight(text)
# Albino.new(text, :ruby)
# end
#
# ... view file ...
# <%= highlight text %>
#
# The default lexer is 'text'. You need to specify a lexer yourself;
# because we are using STDIN there is no auto-detect.
#
# To see all lexers and formatters available, run `pygmentize -L`.
