| 27 * Simple if statement processor | |
| 28 * | |
| 29 * This module can be used to evaluate string representations of C language | |
| 30 * if constructs. It accepts the following grammar: | |
| 31 * | |
| 32 * EXPRESSION := VALUE | |
| 33 * | VALUE BINOP EXPRESSION | |
| 34 * | VALUE '?' EXPRESSION ':' EXPRESSION | |
| 35 * | |
| 36 * VALUE := '(' EXPRESSION ')' | |
| 37 * | '!' VALUE | |
| 38 * | '-' VALUE | |
| 39 * | '~' VALUE | |
| 40 * | 'defined' '(' variable ')' | |
| 41 * | variable | |
| 42 * | number | |
| 43 * | |
| 44 * BINOP := '*' | '/' | '%' | |
| 45 * | '+' | '-' | |
| 46 * | '<<' | '>>' | |
| 47 * | '<' | '>' | '<=' | '>=' | |
| 48 * | '==' | '!=' | |
| 49 * | '&' | '^' | '|' | |
| 50 * | '&&' | '||' | |
| 51 * | |
| 52 * The normal C order of precedence is supported. | |
