usage_description="
Queries the BitBucket.org API

Can specify \$CURL_OPTS for options to pass to curl, or pass them as arguments to the script

Automatically handles authentication via environment variables \$BITBUCKER_USER and \$BITBUCKET_TOKEN
If either of these are not found, tries to infer from local git repo's bitbucket remotes

You must set up a personal access token here:

https://bitbucket.org/account/settings/app-passwords/


API Reference:

https://developer.atlassian.com/bitbucket/api/2/reference/
https://developer.atlassian.com/bitbucket/api/2/reference/resource/


Examples:


# Get currently authenticated user:

${0##*/} /user


# Get currently authenticated user's workspaces:

${0##*/} /workspaces


# Get repos in given workspace:

${0##*/} /repositories/harisekhon


# Get a repo's BitBucket Pipelines [oldest first] (must have a slash on the end otherwise gets 404 error):

${0##*/} /repositories/harisekhon/devops-bash-tools/pipelines/


# Update a repo's description:

${0##*/} /repositories/harisekhon/devops-bash-tools -X PUT -H 'Content-Type: application/json' -d '{\"description\": \"some words\"}'
