Node lookup and scoping rules.
This module contains the "state" of the parser. It keeps track of the discovered nodes and graphs and the scopes they are in.
| def frontEnd.IF1.environment.scope | ( | subGraph | ) |
Create a new scope and push it on top of the stack.
| def frontEnd.IF1.environment.scopeCompound | ( | ) |
Create a new compound scope and push it on top of the stack.
| def frontEnd.IF1.environment.popScope | ( | ) |
Remove the current scope.
Returns to the previous scope.
| def frontEnd.IF1.environment.getNode | ( | label | ) |
Get the node with label in the current scope.
| label | The label to look for. |
| def frontEnd.IF1.environment.addNode | ( | label, | |
| node | |||
| ) |
Add node with label to the current scope.
| label | The IF1 label of the node. |
| node | The node to add |
| def frontEnd.IF1.environment.getSubGraph | ( | ) |
Get the subgraph of the current scope.
| def frontEnd.IF1.environment.addSubGraph | ( | graph | ) |
Add a subgraph to the compound scope.
This will cause errors if the current scope is not a compound scope.
| def frontEnd.IF1.environment.getSubGraphs | ( | ) |
Get the subgraphs.
This will cause errors if the current scope is not a compound scope.
| def frontEnd.IF1.environment.isCompound | ( | ) |
Are we currently in a compound node?
| def frontEnd.IF1.environment.enterComp | ( | ) |
Enter a compound node.
| def frontEnd.IF1.environment.exitComp | ( | ) |
Exit a compound node.
| tuple frontEnd.IF1.environment.log = logging.getLogger(__name__) |
| list frontEnd.IF1.environment.__STACK__ = [Scope()] |
A stack with the global scope at the bottom, and the current scope at the top.
| int frontEnd.IF1.environment.__COMP_LEVEL__ = 0 |
Keeps track of the level of depth w.r.t.
a compound definition.
This allows us to handle nested compound nodes without issues.
