# There are two types of parser skeletons:
|
|
#
|
|
# * Those that can be used with any Yacc implementation, including bison.
|
|
# For these, in the configure.ac, up to Autoconf 2.69, you could use
|
|
# AC_PROG_YACC
|
|
# In newer Autoconf versions, however, this macro is broken. See
|
|
# https://lists.gnu.org/archive/html/autoconf-patches/2013-03/msg00000.html
|
|
# https://lists.gnu.org/archive/html/bug-autoconf/2018-12/msg00001.html
|
|
# In the Makefile.am you could use
|
|
# $(SHELL) $(YLWRAP) $(srcdir)/foo.y \
|
|
# y.tab.c foo.c \
|
|
# y.tab.h foo.h \
|
|
# y.output foo.output \
|
|
# -- $(YACC) $(YFLAGS) $(AM_YFLAGS)
|
|
# or similar.
|
|
#
|
|
# * Those that make use of Bison extensions. For example,
|
|
# - %define api.pure requires bison 2.7 or newer,
|
|
# - %precedence requires bison 3.0 or newer.
|
|
# For these, in the configure.ac you will need an invocation of
|
|
# gl_PROG_BISON([VARIABLE], [MIN_BISON_VERSION])
|
|
# Example:
|
|
# gl_PROG_BISON([PARSE_DATETIME_BISON], [2.4])
|
|
# With this preparation, in the Makefile.am there are two ways to formulate
|
|
# the invocation. Both are direct, without use of 'ylwrap'.
|
|
# (a) You can invoke
|
|
# $(VARIABLE) -d $(SOME_BISON_OPTIONS) --output foo.c $(srcdir)/foo.y
|
|
# or similar.
|
|
# (b) If you want the invocation to honor an YFLAGS=... parameter passed to
|
|
# 'configure' or an YFLAGS environment variable present at 'configure'
|
|
# time, add an invocation of gl_BISON to the configure.ac, and write
|
|
# $(VARIABLE) -d $(YFLAGS) $(AM_YFLAGS) $(srcdir)/foo.y
|
|
# or similar.
|
|
|
|
# This macro defines the autoconf variable VARIABLE to 'bison' if the specified
|
|
# minimum version of bison is found in $PATH, or to ':' otherwise.
