Overview
A custom InputMethod class used by ::XMP for evaluating string io.
Class Method Summary
-
.new ⇒ StringInputMethod
constructor
Creates a new
StringInputMethod
object.
::IRB::InputMethod - Inherited
.new | Creates a new input method object. |
Instance Attribute Summary
-
#encoding
readonly
Returns the encoding of last expression printed by #puts.
-
#eof? ⇒ Boolean
readonly
Whether there are any expressions left in this printer.
::IRB::InputMethod - Inherited
#prompt | The irb prompt associated with this input method. |
#file_name | The file name of this input method, usually given during initialization. |
#readable_after_eof? | Whether this input method is still readable when there is no more data to read. |
Instance Method Summary
-
#gets
Reads the next expression from this printer.
-
#puts(exps)
Concatenates all expressions in this printer, separated by newlines.
