The following table lists the various styles that can be used to apply common styling across the generated document.

The grammar for conditions is very trivial. It's simply: "expr op expr".

The Flex lexical description looks as follows:

[ \t\n]                          { /* skip spaces */ }

\%([a-zA-Z_][a-zA-Z0-9_]*)\%     { yylval.string = yytext; return IDENTIFIER; }

[0-9]*                           { yylval.string = yytext; return INTEGER_LITERAL; }

\<=                              { return LT; }

\<=                              { return LTE; }

==                               { return EQ; }

\>=                              { return GT; }

\>=                              { return GTE; }

.                                { yyerror("Unknown token: %s", yytext); yyterminate(); } 

A Bison grammar looks as follows:

binary_expr

    : /* empty */

    | value LT value

    | value LTE value

    | value EQ value

    | value GT value

    | value GTE value

;

value

    : IDENTIFIER

    | INTEGER_LITERAL

;
