OpenAPI YAML Mode

An Emacs major mode for OpenAPI YAML files. OpenAPI YAML mode supports OpenAPI 2 and 3. OpenAPI 2 files are identical to the Swagger 2 files.

OpenAPI YAML mode is based on yaml-mode, but uses a different strategy for syntax highlight that takes into consideration the OpenAPI specification.

OpenAPI YAML mode is under initial development and is not yet stable.

Features

• Syntax highlight based on the OpenAPI specification (version 2 and 3).
• Basic completion with completion-at-point. Works with Company through the CAPF back-end.
• IMenu for paths and operationIds.

Complementary packages

• Swagger 2 validation can be added with flycheck-swagger-cli or flycheck-swagger-tools.

Customizations

Use the yaml-mode syntax highlight

The defcustom variable openapi-yaml-use-yaml-mode-syntax-highlight can be used to disable the OpenAPI syntax highlight of OpenAPI YAML Mode. The default syntax highlight of yaml-mode is used instead.
