Utility commands

In addition to the sticker picker widget itself, this project includes some utility scripts you can use to import and create sticker packs.

To get started, install the dependencies for using the commands:

0. Make sure you have Python 3.6 or higher.
1. (Optional) Set up a virtual environment.
   1. Create with virtualenv -p python3 .venv
   2. Activate with source .venv/bin/activate
2. Install the utility commands and their dependencies with pip install .

Importing packs from Telegram

To import packs from Telegram, simply run sticker-import <pack urls...> with one or more t.me/addstickers/... URLs.

If you want to list the URLs of all your saved packs, use sticker-import --list. This requires logging in with your account instead of a bot token.

Notes:

• On the first run, it'll prompt you to log in to Matrix and Telegram.
• The Matrix URL and access token are stored in config.json by default.
• The Telethon session data is stored in sticker-import.session by default.
• By default, the pack data will be written to web/packs/.
• You can pass as many pack URLs as you want.
• You can re-run the command with the same URLs to update packs.

Creating your own packs

1. Create a directory with your sticker images.
   • The file name (excluding extension) will be used as the caption.
   • The directory name will be used as the pack name/ID.
   • If you want the stickers to appear in a specific order, prefix them with number-, e.g. 01-Cat.png. The number and dash won't be included in the caption.
2. Run sticker-pack <pack directory>.
   • If you want to override the pack displayname, pass --title <custom title>.
   • Pass --add-to-index web/packs/ if you want to automatically add the generated pack to your sticker picker.

Enabling the sticker widget

1. Serve everything under web/ using your webserver of choice. Make sure not to serve the top-level data, as config.json and the Telethon session file contain sensitive data.

2. Using /devtools in Element Web, edit the m.widgets account data event to have the following content:

   {
       "stickerpicker": {
           "content": {
               "type": "m.stickerpicker",
               "url": "https://your.sticker.picker.url/?theme=$theme",
               "name": "Stickerpicker",
               "data": {}
           },
           "sender": "@you:picker.url",
           "state_key": "stickerpicker",
           "type": "m.widget",
           "id": "stickerpicker"
       }
   }
   

   If you do not yet have a m.widgets event, simply create it with that content. You can also use the client-server API directly instead of using Element Web.

   The theme=$theme query parameter will make the widget conform to Element's theme automatically. You can also use light, dark or black instead of $theme to always use a specific theme.

   You can use https://maunium.net/stickers-demo/ as the URL to try out the picker without hosting the files yourself.

3. Open the sticker picker and enjoy the fast sticker picking experience.
