Note

We implemented a custom syntax definition mechanism in VCL, it means we bring special syntax (statement, token, etc) only for falco rutime.
In terms of this, we specified tokenization/parser spec at https://github.com/ysugimoto/falco/blob/main/docs/parser.md.

For testing, we define grouped testing like describe keyword using custom syntax. See https://github.com/ysugimoto/falco/blob/main/docs/testing.md#grouped-testing in detail.

Imporatnt

Fastly says that an NGWAF configuration will be provided via Fastly managed dynamic snippet and probably cannot be modified.
Then Falco will raise a linting error for it, so it should be ignored by the configuration. If you're using NGWAF in your deliver service, probably this configuration is needed. see configuration.md
