---|
| 7 | * The general idea here is that we want to parse a config.in file and |
---|
| 8 | * from this, we generate a wish script which gives us effectively the |
---|
| 9 | * same functionality that the original config.in script provided. |
---|
| 10 | * |
---|
| 11 | * This task is split roughly into 3 parts. The first parse is the parse |
---|
| 12 | * of the input file itself. The second part is where we analyze the |
---|
| 13 | * #ifdef clauses, and attach a linked list of tokens to each of the |
---|
| 14 | * menu items. In this way, each menu item has a complete list of |
---|
| 15 | * dependencies that are used to enable/disable the options. |
---|
| 16 | * The third part is to take the configuration database we have build, |
---|
| 17 | * and build the actual wish script. |
---|
| 18 | * |
---|
| 19 | * This file contains the code to further process the conditions from |
---|
| 20 | * the "ifdef" clauses. |
---|
| 21 | * |
---|
| 22 | * The conditions are assumed to be one of the following formats |
---|
| 23 | * |
---|
| 24 | * simple_condition:= "$VARIABLE" == y/n/m |
---|
| 25 | * simple_condition:= "$VARIABLE != y/n/m |
---|
| 26 | * |
---|
| 27 | * simple_condition -a simple_condition |
---|
| 28 | * |
---|
| 29 | * If the input condition contains '(' or ')' it would screw us up, but for now |
---|
| 30 | * this is not a problem. |
