"""Generates TypeScript files that import all subdirectories and
|
|
registers them with plugin registry. If you have three modules:
|
|
- core/
|
|
- plugins/foo_plugin/
|
|
- plugins/bar_plugin/
|
|
In general you would like the dependency to only go one way:
|
|
- plugins/foo_plugin/ -> core/
|
|
We want to avoid manually editing core/ for every plugin.
|
|
|
|
This generates code like:
|
|
|
|
import {pluginRegistry} from '../common/plugins';
|
|
|
|
import {plugin as fooPlugin} from '../plugins/foo_plugin';
|
|
import {plugin as barPlugin} from '../plugins/bar_plugin';
|
|
|
|
pluginRegistry.register(fooPlugin);
|
|
pluginRegistry.register(barPlugin);
|
|
