#!/bin/bash -e

# Use this script to retrieve the following InfluxData API specifications:
# - the latest, fully resolved openapi (OAS, OpenAPI Specification) contract files from the influxdata/openapi repo
#
# Specify a product to retrieve (cloud-serverless, cloud-dedicated, clustered, cloud, v2, v1-compatibility, all).
# Optionally specify:
# - an OSS version as the second argument or using the -o flag.
#   The version specifies where to write the updated openapi.
#   The default version is the latest OSS version directory in the api-docs directory.
# - a base URL using the -b flag.
#   The baseURL specifies where to retrieve the openapi files from.
#   The default baseUrl (used for InfluxDB Cloud) is the master branch of influxdata/openapi.
#   The default baseUrl for OSS is the docs-release/influxdb-oss branch of influxdata/openapi.
#   For local development, pass your openapi directory using the file:/// protocol.
#   To use the existing ref.yml and prevent fetching any openapi files, use the -B flag.
# Syntax:
#   sh ./getswagger.sh <product>
#   sh ./getswagger.sh <product> -b <baseUrl>
#   sh ./getswagger.sh -c <product> -o <version> -b <baseUrl>
#   sh ./getswagger.sh -c <product> -o <version> -B
#
# Examples:
#   sh ./getswagger.sh cloud-serverless
#   sh ./getswagger.sh clustered -B
#   sh ./getswagger.sh cloud
#   sh ./getswagger.sh -c v2 -o v2.0 -b file:///Users/johnsmith/github/openapi
