A custom InputMethod class used by
XMP for evaluating string io.
Returns the encoding of last expression printed by
Whether there are any expressions left in this printer.
# File lib/irb/xmp.rb, line 108 def eof? @exps.empty? end
Reads the next expression from this printer.
IO#gets for more information.
# File lib/irb/xmp.rb, line 115 def gets while l = @exps.shift next if /^\s+$/ =~ l l.concat "\n" print @prompt, l break end l end
Concatenates all expressions in this printer, separated by newlines.
Encoding::CompatibilityError is raised of the given
exps's encoding doesn't match the previous expression evaluated.
# File lib/irb/xmp.rb, line 129 def puts(exps) if @encoding and exps.encoding != @encoding enc = Encoding.compatible?(@exps.join("\n"), exps) if enc.nil? raise Encoding::CompatibilityError, "Encoding in which the passed expression is encoded is not compatible to the preceding's one" else @encoding = enc end else @encoding = exps.encoding end @exps.concat exps.split(/\n/) end
