# Call Hierarchy Provider Sample
|
||||
|
||||
This sample shows the **Call Hierarchy** in action based on a simple food pyramid model defined using simple subject~verb~object syntax.
|
||||
|
||||
|
||||
|
||||
## VS Code API
|
||||
|
||||
### `vscode` module
|
||||
|
||||
- [`languages.registerCallHierarchyProvider`](https://code.visualstudio.com/api/references/vscode-api#languages.registerCallHierarchyProvider)
|
||||
- [`CallHierarchyProvider`](https://code.visualstudio.com/api/references/vscode-api#CallHierarchyProvider)
|
||||
|
||||
## Running the Sample
|
||||
|
||||
Start the extension in the debugger and it automatically opens a file that is ready for the right-click > Peek Call Hierarchy. Otherwise, it can be testing by creating a file with extension `.txt` and pasting following text:
|
||||
|
||||
```plaintext
|
||||
Coyote eats deer.
|
||||
Deer eats plants.
|
||||
Coyote eats lizard.
|
||||
Lizard eats bird.
|
||||
Lizard eats frog.
|
||||
Lizard eats butterfly.
|
||||
Bird eats seeds.
|
||||
Frog eats insects.
|
||||
Butterfly eats fruit.
|
||||
```
|
||||
|
||||
Right click on a noun or a verb and select _Peek Call Hierarchy_.
|
||||
|
||||
## Contributing to the Sample and Testing the Sample
|
||||
|
||||
Run the _Run Extension Tests_ configuration and verify in the Debug Console that all tests are passing.
