usage_description="
Queries the CircleCI API

Requires \$CIRCLECI_TOKEN in the environment

Can specify \$CURL_OPTS for options to pass to curl or provide them as arguments


Set up a personal access token here:

    https://app.circleci.com/settings/user/tokens


API Reference:

    https://circleci.com/docs/api/v2/
    https://circleci.com/docs/api/v1/


The CircleCI API isn't very mature, so sometimes you need to go back and use the v1.1 API instead of the default v2 API, so if the path starts with /v1.1 it'll use that API instead


Examples:


# Get currently authenticated user:

    ${0##*/} /me | jq .


# List projects (requires v1.1 API, no endpoint in v2 yet):

    ${0##*/} /v1.1/projects | jq .


# Get a project:

    ${0##*/} /project/<vcs>/<user_or_org>/<repo>

    ${0##*/} /project/github/HariSekhon/DevOps-Bash-tools | jq .


# Get a list of pipeline runs for a project:

    ${0##*/} /project/<vcs>/<user_or_org>/<repo>/pipeline

    ${0##*/} /project/github/HariSekhon/DevOps-Bash-tools/pipeline | jq .

    # just the pipelines triggered by you

    ${0##*/} /project/<vcs>/<user_or_org>/<repo>/pipeline/mine

    ${0##*/} /project/github/HariSekhon/DevOps-Bash-tools/pipeline/mine | jq .


# Get environment variables for a project (see circleci_project_set_env_vars.sh to easily set them):

    ${0##*/} /project/<vcs>/<user_or_org>/<repo>/envvar

    ${0##*/} /project/github/HariSekhon/DevOps-Bash-tools/envvar | jq .

# see circleci_project_set_env_vars.sh to easily set these variables


# Create / replace a project environment variable:

    ${0##*/} /project/<vcs>/<user_or_org>/<repo>/envvar -X POST -d '{\"name\": \"AWS_ACCESS_KEY_ID\", \"value\": \"AKIA...\"}'

    ${0##*/} /project/github/HariSekhon/DevOps-Bash-tools/envvar -X POST -d '{\"name\": \"AWS_ACCESS_KEY_ID\", \"value\": \"AKIA...\"}' | jq .


# List contexts for a user or organization (this org id is different to a user id even for a user's context):
#                                          (organization ID can be found on organization settings page as it is not currently exposed in the API)
#                                          (find organization ID here: https://app.circleci.com/settings/organization/VCS/MY_USER_OR_ORG/contexts)
#                                                                  eg. https://app.circleci.com/settings/organization/github/HariSekhon/contexts

    ${0##*/} '/context/<context_id>/environment-variable' | jq .


# Use the context ID from the above output to list environment variable secrets from the given context ID

    ${0##*/} /context/c2321a8a-c188-4568-aac7-aef89cb7a6e2/environment-variable | jq .

# see circleci_context_set_env_vars.sh to easily set these variables
