PrettyPrint::SingleLine is used by PrettyPrint.singleline_format
It is passed to be similar to a PrettyPrint object itself, by responding to:
but instead, the output has no line breaks
# File tmp/rubies/ruby-2.4.10/lib/prettyprint.rb, line 503
def initialize(output, maxwidth=nil, newline=nil)
@output = output
@first = [true]
end
Create a PrettyPrint::SingleLine object
Arguments:
-
output- String (or similar) to store rendered text. Needs to respond to ‘<<’ -
maxwidth- Argument position expected to be here for compatibility.This argument is a noop.
-
newline- Argument position expected to be here for compatibility.This argument is a noop.
# File tmp/rubies/ruby-2.4.10/lib/prettyprint.rb, line 518
def breakable(sep=' ', width=nil)
@output << sep
end
Appends sep to the text to be output. By default sep is ‘ ’
width argument is here for compatibility. It is a noop argument.

def first?
result = @first[-1]
@first[-1] = false
result
end
This is used as a predicate, and ought to be called first.

def group(indent=nil, open_obj='', close_obj='', open_width=nil, close_width=nil)
@first.push true
@output << open_obj
yield
@output << close_obj
@first.pop
end
Opens a block for grouping objects to be pretty printed.
Arguments:
-
indent- noop argument. Present for compatibility. -
open_obj- text appended before the &blok. Default is ” -
close_obj- text appended after the &blok. Default is ” -
open_width- noop argument. Present for compatibility. -
close_width- noop argument. Present for compatibility.

def text(obj, width=nil)
@output << obj
end
Add obj to the text to be output.
