Generate programs for lexical tasks.
| -c |
Indicate C-language action (default option). |
| -n |
Suppress the summary of statistics usually written with the -v option. If no table sizes are
specified in the lex source code and the -v option is not specified, then -n is implied. |
| -t |
Write the resulting program to standard output instead of lex.yy.c. |
| -v |
Write a summary of lex statistics to the standard error. (See the discussion of lex table sizes under the heading Definitions in lex.) If table
sizes are specified in the lex source code, and if the -n option is not specified, the -v option may be enabled. |
| -e |
Generate a program that can handle EUC characters (cannot be used with the -w option). yytext[] is of type unsigned char[]. |
| -w |
Generate a program that can handle EUC characters (cannot be used with the -e option). Unlike the -e option,
yytext[] is of type wchar_t[]. |
| -V |
Print out version information on standard error. |
| -Q[y|n] |
Print out version information to output file lex.yy.c by using -Qy. The -Qn option does not print out version information and is the default. |
| file |
A pathname of an input file. If more than one such file is specified, all files will be concatenated to produce a single lex program. If no file operands are specified, or if a file operand is -, the standard input will be used. |
