flex 2.6.0

Usage: flex [OPTIONS] [FILE]... Generates programs that perform pattern-matching on text. Table Compression: -Ca, --align trade off larger tables for better memory alignment -Ce, --ecs construct equivalence classes -Cf do not compress tables; use -f representation -CF do not compress tables; use -F representation -Cm, --meta-ecs construct meta-equivalence classes -Cr, --read use read() instead of stdio for scanner input -f, --full generate fast, large scanner. Same as -Cfr -F, --fast use alternate table representation. Same as -CFr -Cem default compression (same as --ecs --meta-ecs) Debugging: -d, --debug enable debug mode in scanner -b, --backup write backing-up information to lex.backup -p, --perf-report write performance report to stderr -s, --nodefault suppress default rule to ECHO unmatched text -T, --trace flex should run in trace mode -w, --nowarn do not generate warnings -v, --verbose write summary of scanner statistics to stdout --hex use hexadecimal numbers instead of octal in debug outputs Files: -o, --outfile=FILE specify output filename -S, --skel=FILE specify skeleton file -t, --stdout write scanner on stdout instead of lex.yy.c --yyclass=NAME name of C++ class --header-file=FILE create a C header file in addition to the scanner --tables-file[=FILE] write tables to FILE Scanner behavior: -7, --7bit generate 7-bit scanner -8, --8bit generate 8-bit scanner -B, --batch generate batch scanner (opposite of -I) -i, --case-insensitive ignore case in patterns -l, --lex-compat maximal compatibility with original lex -X, --posix-compat maximal compatibility with POSIX lex -I, --interactive generate interactive scanner (opposite of -B) --yylineno track line count in yylineno Generated code: -+, --c++ generate C++ scanner class -Dmacro[=defn] #define macro defn (default defn is '1') -L, --noline suppress #line directives in scanner -P, --prefix=STRING use STRING as prefix instead of "yy" -R, --reentrant generate a reentrant C scanner --bison-bridge scanner for bison pure parser. --bison-locations include yylloc support. --stdinit initialize yyin/yyout to stdin/stdout --noansi-definitions old-style function definitions --noansi-prototypes empty parameter list in prototypes --nounistd do not include <unistd.h> --noFUNCTION do not generate a particular FUNCTION Miscellaneous: -c do-nothing POSIX option -n do-nothing POSIX option -? -h, --help produce this help message -V, --version report flex version
