body:
|
|
|
|
As code is executing in the context of the build process Lektor will
|
|
automatically track dependencies. However in some cases it might be
|
|
useful for a plugin to know exactly which dependencies are recorded.
|
|
|
|
In this case this method can be used as a context manager. Whenever Lektor
|
|
encounters a dependency it will invoke the passed function.
|
|
|
|
## Example
|
|
|
|
```python
|
|
deps = set()
|
|
with get_ctx().gather_dependencies(deps.add):
|
|
items = pad.query('/path/to/some/pages').all()
|
|
print('The dependencies are: %s' % deps)
|
|
```
