Improved how bison and flex are used
Replaced bfok.sh with run_bison.sh and run_flex.sh.
Simplified these Makefile rules:
make jparse.tab.c jparse.tab.h
make jparse.c
make parser
Removed bfok rule.
These Makefile variables:
${BISON}
${FLEX}
${BFOK_DIRS}
have been replaced with:
${BISON_BASENAME}
${BISON_DIRS}
${FLEX_BASENAME}
${FLEX_DIRS}
Here are the usage messages for run_bison.sh and run_flex.sh:
run_bison.sh:
usage: ./run_bison.sh [-h] [-v level] [-V] [-b bison] [-l limit_ioccc.sh]
[-g verge] [-p prefix] [-s sorry.h] [-B dir] .. -- [bison_flags ..]
-h print help and exit 8
-v level set debug level (def: 0)
-V print version and exit 8
-b bison bison tool basename (def: bison)
-l limit_ioccc.sh version info file (def: ./limit_ioccc.sh)
-g verge path to verge tool (def: ./verge)
-p prefix The prefix of files to be used (def: jparse)
NOTE: If the final arg is bison:
NOTE: The bison input file will be prefix.y
NOTE: If bison cannot be used, then these backup files are used:
NOTE:
NOTE: prefix.tab.c prefix.tab.h
NOTE:
-s sorry.h File to prepend to C output (def: sorry.tm.ca.h)
-B dir 1st look for bison in dir (def: look just along $PATH)
NOTE: Multiple -B dir are allowed.
NOTE: Search is performed in dir order before the $PATH path.
NOTE: If dir is missing or not searchable, dir is ignored.
NOTE: This is ignored if the final arg is NOT bison.
-- End of ./run_bison.sh flags
bison_flags .. optional flags to give to bison for the prefix.y argument
