LEX(1) General Commands Manual LEX(1)
NAME
lex - generator of lexical analysis programs
SYNOPSIS
lex [ -tvfn ] [ file ] ...
DESCRIPTION
Lex generates programs to be used in simple lexical analyis of text. The input files (standard input default) contain regular expressions
to be searched for, and actions written in C to be executed when expressions are found.
A C source program, 'lex.yy.c' is generated, to be compiled thus:
cc lex.yy.c -ll
This program, when run, copies unrecognized portions of the input to the output, and executes the associated C action for each regular
expression that is recognized.
The options have the following meanings.
-t Place the result on the standard output instead of in file "lex.yy.c".
-v Print a one-line summary of statistics of the generated analyzer.
-n Opposite of -v; -n is default.
-f "Faster" compilation: don't bother to pack the resulting tables; limited to small programs.
EXAMPLE
lex lexcommands
would draw lex instructions from the file lexcommands, and place the output in lex.yy.c
%%
[A-Z] putchar(yytext[0]+'a'-'A');
[ ]+$ ;
[ ]+ putchar(' ');
is an example of a lex program that would be put into a lex command file. This program converts upper case to lower, removes blanks at the
end of lines, and replaces multiple blanks by single blanks.
