|
# Complain if any name of type WHAT is used by the user (as recorded in
|
|
# USER-LIST) but is not used by Bison (as recorded by macros in the
|
|
# namespace BISON-NAMESPACE).
|
|
#
|
|
# USER-LIST must expand to a list specifying all user occurrences of all names
|
|
# of type WHAT. Each item in the list must be a triplet specifying one
|
|
# occurrence: name, start boundary, and end boundary. Empty string names are
|
|
# fine. An empty list is fine.
|
|
#
|
|
# For example, to define b4_foo_user_names to be used for USER-LIST with three
|
|
# name occurrences and with correct quoting:
|
|
#
|
|
# m4_define([b4_foo_user_names],

|
# [[[[[[bar]], [[parser.y:1.7]], [[parser.y:1.16]]]],

|
|
# [[[[baz]], [[parser.y:8.7]], [[parser.y:8.16]]]]]])
|
|
#
|
|
# The macro BISON-NAMESPACE(bar) must be defined iff the name bar of type WHAT
|
|
# is used by Bison (in the front-end or in the skeleton). Empty string names
|
|
# are fine, but it would be ugly for Bison to actually use one.
|
|
#
|
|
# For example, to use b4_foo_bison_names for BISON-NAMESPACE and define that

# the names bar and baz are used by Bison:

#

# m4_define([b4_foo_bison_names(bar)])
