This feature handily beats \u003ckbd\u003eCtrl\u003c/kbd\u003e+\u003ckbd\u003eF\u003c/kbd\u003e in a PDF file!\n\n### Explore\n\nYou can interactively expand non-terminals (recursively even!) and see possible derivations.\n\n## Contributing\n\nSee [contribution guide](CONTRIBUTING.md).\n\n## Licence\n\n[MIT](LICENCE)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjosephuspaye%2Fgrammar-explorer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjosephuspaye%2Fgrammar-explorer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjosephuspaye%2Fgrammar-explorer/lists"}
