A custom InputMethod class used by XMP for evaluating string io.
Attributes
Public Class Methods
Creates a new StringInputMethod object
# File irb/xmp.rb, line 105
def initialize
super
@exps = []
end
Public Instance Methods
Whether there are any expressions left in this printer.
# File irb/xmp.rb, line 111
def eof?
@exps.empty?
end
Reads the next expression from this printer.
See IO#gets for more information.
# File irb/xmp.rb, line 118
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.
An Encoding::CompatibilityError is raised of the given exps‘s
encoding doesn’t match the previous expression evaluated.
# File irb/xmp.rb, line 132
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/)
