|
|
|
|
This APRSD plugin looks for the location command comming in
|
|
to aprsd, then fetches the caller's location, and then reports
|
|
that location string to the configured slack channel.
|
|
|
|
To use this:
|
|
Create a slack bot for your workspace at api.slack.com.
|
|
A good source of information on how to create the app
|
|
and the tokens and permissions and install the app in your
|
|
workspace is here:
|
|
|
|
https://api.slack.com/start/building/bolt-python
|
|
|
|
|
|
You will need the signing secret from the
|
|
Basic Information -> App Credentials form.
|
|
You will also need the Bot User OAuth Access Token from
|
|
OAuth & Permissions -> OAuth Tokens for Your Team ->
|
|
Bot User OAuth Access Token.
|
|
|
|
Install the app/bot into your workspace.
|
|
|
|
Edit your ~/.config/aprsd/aprsd.yml and add the section
|
|
slack:
|
|
signing_secret: <signing secret token here>
|
|
bot_token: <Bot User OAuth Access Token here>
|
|
channel: <channel name here>
