# script to quickly clone gitlab repositories inside of a fzf session

# usage:
#   - without arguments: shows all available repositories
#   - with arguments: pre filters the search with the given value
#
# dependencies:
#   - fzf, jq, curl, bash
#   - variables.cfg
#     - GITLAB_PROJECTS_URL is the url to the gitlab projects api
#     - GITLAB_ACCESS_TOKEN is the access key from gitlab
