* tools/formed/test-data/simple.xml: Modified to contain a rule. |
| 4 |
|
|
| 5 |
|
* tools/formed/formed/model/expr.py: Added. A simple RPN |
| 6 |
|
expression evaluator. To avoid the problem of eval()ing |
| 7 |
|
arbitrary python expressions I've decided to use a very |
| 8 |
|
basic and limited stack machine to support rule checking. |
| 9 |
|
|
| 10 |
|
* tools/formed/formed/model/data.py: Added a RuleLeaf. |
| 11 |
|
|
| 12 |
|
* tools/formed/formed/io/document.py: Added factories for rules. |
| 13 |
|
|
| 14 |
|
* tools/formed/formed/model/nodecomponents.py: Add a method |
| 15 |
|
to find all items of a given type in document for a given |
| 16 |
|
mode. Usefull to find all rules in the tree. |
| 17 |
|
|
| 18 |
|
* tools/formed/formed/ui/controls.py: Added a listener mechanism |
| 19 |
|
to attribute table to report exceptions when setting a value |
| 20 |
|
from GUI. Useful to report compilation errors when setting |
| 21 |
|
expr of rule leafs. |
| 22 |
|
|
| 23 |
|
* tools/formed/formed/main.py: Added a method to track exceptions |
| 24 |
|
from the attribute table and pop up dialogs if they occur. |
| 25 |
|
Added a counter of rule modifications in tree. Useful if you |
| 26 |
|
want build cached data structures like rule sets and you want |
| 27 |
|
to know if they are still valid. |
