tusk

A tiny command line wrapper for creating OAuth2 apps for the Mastodon API and using them with curl.

Installation

1. Install jq.
2. Put tusk somewhere in your PATH: install tusk /usr/local/bin

Setup

You will create multiple files here: one for your app (custom bot code/script/etc), and one for each Mastodon account that uses that app.

1. Create an app:

   tusk -A my-app.json -n 'My App'
   

   The name (-n) is required, and will be shown when asking accounts for approval. You can optionally specify a website with -w or change the scope from the default of read write with -s.

2. Create an access token:

   tusk -a my-app.json -T token.json
   

   This will ask you to open a URL in a browser where you're logged in as your bot's account. Do that, approve the request, and come back with the approval code. You now have a token!

3. Use the token as your bot:

   tusk -t token.json /accounts/verify_credentials
   

That's it! To help you remember the setup options: uppercase letters (-A, -T) will write files (without asking to overwrite, so be careful!), and lowercase letters will read those files. It's up to you where to store the files, but keep in mind that token contents don't say what account they are for or that account's ID, so you may want to put that info in the filename.

Examples

Once you're set up with a token, a tusk command line is basically like a curl command line, but instead of curl options followed by a URL, it goes in this order:

1. tusk options (to set the Mastodon instance and token)
2. An API resource name (only the part after the base API URI)
3. curl options

• To illustrate, here's how you would change your display name after creating a token in token.json:

  tusk -t token.json /accounts/update_credentials -X PATCH -F display_name="Today's display name"
  

  (This is actually why I wrote tusk! Instead of a literal value there, I'm using my nickname followed by a new randomly-selected emoji each day, as a goof on the early Mastodon meme of putting a ✅ emoji after your name as a fake "verified" symbol.)

• Here's how you could list the accounts you're following:

  my_id=$(tusk -t token.json /accounts/verify_credentials | jq .id)
  tusk -t token.json /accounts/"$my_id"/following | jq -r '.[].acct'
  

  Your user ID doesn't change, so as mentioned above, in real-world usage you'd probably want to save it rather than looking it up every time.

Using Another Instance

If you wanted to use a different instance, say, awoo.space instead, start all your commands (including setup) with:

tusk -i https://awoo.space

Thanks

Darius Kazemi implemented a hybrid web form/curl command method of creating an app and token, which inspired this.

If you create a bot using this script, I'd love to hear about it. I'm @decklin@mastodon.social and am going to set up some bots on botsin.space soon.
