module PP::PPMethods

Check whether the object_id id is in the current buffer of objects to be pretty printed. Used to break cycles in chains of objects to be pretty printed.

A convenience method which is same as follows:

text ','
breakable

Yields to a block and preserves the previous set of objects being printed.

A convenience method, like object_group, but also reformats the Object’s object_id.

A convenience method which is same as follows:

group(1, '#<' + obj.class.name, '>') { ... }

Removes an object from the set of objects being pretty printed.

Adds obj to the pretty printing buffer using Object#pretty_print or Object#pretty_print_cycle.

Object#pretty_print_cycle is used when obj is already printed, a.k.a the object reference chain has a cycle.

A pretty print for a Hash

A present standard failsafe for pretty printing any given Object

Adds the object_id id to the set of objects being pretty printed, so as to not repeat objects.

Adds a separated list. The list is separated by comma with breakable space, by default.

seplist iterates the list using iter_method. It yields each object to the block given for seplist. The procedure separator_proc is called between each yields.

If the iteration is zero times, separator_proc is not called at all.

If separator_proc is nil or not given, +lambda { comma_breakable }+ is used. If iter_method is not given, :each is used.

For example, following 3 code fragments has similar effect.

q.seplist([1,2,3]) {|v| xxx v }

q.seplist([1,2,3], lambda { q.comma_breakable }, :each) {|v| xxx v }

xxx 1
q.comma_breakable
xxx 2
q.comma_breakable
xxx 3
