# -------------------------------------------------------------
# Using TITLE as the test group title, check the generated parser tables
# and parser for a specified grammar file under a condition labeled by
# COND-VALUE.
#
# TEST-SPEC is a comma-delimited list of attributes of this test.  Each
# recognized attribute is described below where it is relevant.
#
# Insert DECLS and GRAMMAR into the declarations and grammar section of
# the grammar file.  Insert basic yyerror, yylex, and main function
# definitions as well.  Hardcode yylex to return the (possibly empty)
# comma-delimited series of tokens in INPUT followed by token 0.
#
# If TEST-SPEC contains the attribute no-xml, then invoke bison using
# AT_BISON_CHECK_NO_XML.  Otherwise, invoke bison using AT_BISON_CHECK.
# On the bison command-line, specify `--report=all --defines'.  Check
# that Bison exits with value 0, has no stdout, and has stderr
# BISON-STDERR.
#
# If TEST-SPEC contains the attribute `last-state', check that the value
# of TABLES-OR-LAST-STATE is the index of the last state generated for
# the grammar; in other words, check the number of states (minus one).
# Otherwise, check that everything in the `.output' file starting with
# the definition of state 0 is the same as the entire value of
# TABLES-OR-LAST-STATE.
#
# Expand the M4 in OTHER-CHECKS to perform additional checks of the
# `.output' file, which is named `input.output', and/or grammar file,
# which is named `input.y'.
#
# Finally, compile the generated parser and then run it using
# AT_PARSER_CHECK with PARSER-EXIT-VALUE, PARSER-STDOUT, and
# PARSER-STDERR as the 2nd-4th arguments.
#
# As a precondition, you must properly double-quote all arguments that
# are to be interpreted as strings.
#
# AT_COND_CASE (when appearing in single-quoted segments of arguments)
# invokes m4_case with its own arguments but COND-VALUE inserted as the
# first argument.  This is useful, for example, when wrapping multiple
# AT_TEST_TABLES_AND_PARSE invocations, each representing a different
# condition, in another macro.
#

#
