Function preprocess

preprocess(source: string, options?: MwlPreprocessOptions): string
Expands MWL macros, #ifdef blocks and #includes into flat source text, then rewrites the _("...") gettext marker into a form the JSON5 parser accepts. The marker keeps working because this pass already runs before structural parsing, the same reason macros survive a change of grammar.
Parameters
- source: string
- options: MwlPreprocessOptions = {}
Returns string
Example
```
import { preprocess } from '@datamoc/mw_games/mwl';

console.log(preprocess("[{ tag: 'game', schema: 0.1 }]"));
```
