  9Have you ever used GitLab to host your source code, moved to a different host,
 10and wanted to delete everything from your GitLab account? Well, this post covers
 11any scenario where you would want to delete all repositories from your GitLab
 12account.
 13
 14For me, I currently maintain around 30 repositories and don't like to manually
 15delete them whenever I switch host. GitHub has a few different tools online to
 16delete all repositories for you, but I have not found anything similar for
 17GitLab, so I needed an alternative solution.
 18
 19* Use a Python Script
 20
 21** Requirements
 22
 23Before we look at the script, make sure you know your GitLab username. Next,
 24[[https://gitlab.com/-/profile/personal_access_tokens][create an authorization token]] so that the Python script can delete your
 25repositories. Don't lose this token or else you'll need to create a new one.
 26
 27** Create the Script
 28
 29To run a Python script, you must first create it. Open a terminal and enter the
 30following commands in whichever directory you prefer to store the script. You
 31can do the same things in a file manager if you prefer.
 32
 33#+begin_src sh
 34mkdir delete-gitlab
 35#+end_src
 36
 37#+begin_src sh
 38cd delete-gitlab
 39#+end_src
 40
 41#+begin_src sh
 42nano main.py
 43#+end_src
 44
 45Enter the following code into your =main.py= script.
 46
 47#+begin_src python
 48import request
 49import json
 50
 51
 52def get_project_ids():
 53    url = "https://gitlab.com/api/v4/users/{user-id}/projects"
 54
 55    querystring = {"owned": "true", "simple": "true", "per_page": "50"}
 56
 57    payload = ""
 58    headers = {'authorization': 'Bearer {auth-token}'}
 59
 60    response = requests.request("GET", url, data=payload, headers=headers, params=querystring)
 61
 62    projects = json.loads(response.text)
 63    projects_ids = list(map(lambda project: project.get('id'), projects))
 64
 65    return projects_ids
 66
 67
 68def remove_project(project_id):
 69    url_temp = "https://gitlab.com/api/v4/projects/{project}"
 70    headers = {'authorization': 'Bearer {auth-token}'}
 71    querystring = ""
 72    payload = ""
 73
 74    url = url_temp.format(project=project_id)
 75
 76    response = requests.request("DELETE", url, data=payload, headers=headers, params=querystring)
 77    project = json.loads(response.text)
 78    print(project)
 79
 80
 81def main():
 82    projects_ids = get_project_ids()
 83
 84    url_temp = "https://gitlab.com/api/v4/projects/{project}"
 85    headers = {'authorization': 'Bearer {auth-token}'}
 86    querystring = ""
 87    payload = ""
 88
 89    for project_id in projects_ids:
 90        url = url_temp.format(project=project_id)
 91
 92        response = requests.request("GET", url, data=payload, headers=headers, params=querystring)
 93        project = json.loads(response.text)
 94        print(str(project.get('id')) + " " + project.get('name'))
 95        print("Removing...")
 96        remove_project(project_id)
 97
 98
 99if __name__ == "__main__":
100    main()
101#+end_src
102
103Now that you have the proper information, replace ={user-id}= with your GitLab
104username and ={auth-token}= with the authorization token you created earlier.
105
106Finally, simply run the script and watch the output. You can also use PyCharm
107Community Edition to edit and run the Python script if you don't want to work in
108a terminal.

112#+end_src
