MetaGame XP Instance

This repository contains MetaGame's SourceCred instance.

About SourceCred Instances

SourceCred is organized around "instances". Every instance must have a sourcecred.json file at root, which specifies which plugins are active in the instance. Config and permanent data (e.g. the Ledger) are stored in the master branch. All output or site data gets stored in the gh-pages branch by the Github Action.

Configuration files:

• config/grain.json specifies how much Grain to distribute every week. The maxSimultaneousDistributions parameter determines how many weeks of "back-distributions" to generate if the command hasn't been run in a while (or ever).
• config/plugins/$PLUGIN_OWNER/$PLUGIN_NAME stores plugin-specific data. Each plugin has its own directory. See the plugin section below to learn how to configure them.

Permanent Data:

• data/ledger.json keeps a history of all grain distributions and transfers as well as identities added / merged.

Generated Data:

• cache/ stores intermediate produced by the plugins. This directory should not be checked into Git at all.
• output/ stores output data generated by SourceCred, including the Cred Graph and Cred Scores. This directory should be checked into Git; when needed, it may be removed and re-generated by SourceCred.
• site/ which stores the compiled SourceCred frontend, which can display data stored in the instance.

Setup and Usage

Using this instance as a starting point, you can update the config to include just the plugins you want, pointing at the data you care about. We recommend setting up your instance locally first and make sure its working before pushing your changes to master and using the Github Action.

Get Yarn and then run yarn to install SourceCred and dependencies.

Update the configuration files according to the plugin guides below.

Then, run the following commands to update the instance:

• yarn load [...plugins] loads the cache. By default, it loads all plugins, or it can load only specific plugins if requested.
• yarn graph [...plugins] regenerates plugin graphs from the cache; these graphs get saved in output/
• yarn score computes Cred scores, combining data from all the chosen plugins
• yarn grain distributes Grain according to the current Cred scores, and the config in config/grain.json

Generate the frontend:

• yarn site

Run the frontend:

• yarn admin

If you want to clear the cached data, you can do so via:

• yarn clean

Running yarn clean is a good idea if any plugins fail to load.

If you want to restart from a clean slate and remove all the generated graphs, you can do so via:

• yarn clean-all

Run yarn clean-all if the yarn graph command fails due to a change in the config or breaking changes in a new version of SourceCred. Warning: If you don't have credentials for every plugin, you might not be able to regenerate parts of the graph.

Publishing on GitHub pages

Once you've got the instance configured to your satisfaction (see instructions on plugins below), commit and push your changes to master (or make a pull request). The Github Action will then generate the frontend and deploy it to GitHub Pages. To enable GitHub Pages for your instance, check out this guide. Make sure you select gh-pages as the branch to publish from.

Supported Plugins

GitHub

The GitHub plugin loads GitHub repositories.

You can specify the repositories to load in config/plugins/sourcecred/github/config.json.

The Github Action automatically has its own GITHUB_TOKEN, but if you need to load data from the GitHub plugin locally, you must have a GitHub API key in your environment as $SOURCECRED_GITHUB_TOKEN. The key should be read-only without any special permissions (unless you are loading a private GitHub repository, in which case the key needs access to your private repositories).

You can generate a GitHub API key here.

Discourse

The Discourse plugin loads Discourse forums; currently, only one forum can be loaded in any single instance. This does not require any special API keys or permissions. You just need to set the server url in config/plugins/sourcecred/discourse/config.json.

Discord

The Discord plugin loads Discord servers, and mints cred on Discord reactions.

To get this setup, you'll first want to enable Developer Mode in your Discord client, under User Settings -> Appearance -> Advanced -> Developer Mode. This will give you the ability to right-click on items and copy their Discord ids.

Then, right click on the server you want to track, and copy its ID. Modify the config/plugins/sourcecred/discord/config.json file to have the correct guildId.

Next, you'll need to create a Discord application and add it to the server. (This requires admin permissions on that server.)

The first step is to create an application, which you can do here: https://discordapp.com/developers/applications

You'll get an application client ID, which you'll need in a future step.

Next, give that application a Bot by clicking on the "Bot" menu option on the left, and then adding a bot. The bot will have a token, which you should also save.

Once you've made the bot, you need to invite it to your server. You'll need to do so by constructing a URL like:

https://discordapp.com/api/oauth2/authorize?client_id=${CLIENT_ID}&scope=bot&permissions=66560

Where ${CLIENT_ID} should be replaced with your application's client id from above. For example, if your application's client id is 1234, use the following url:

https://discordapp.com/api/oauth2/authorize?client_id=1234&scope=bot&permissions=66560

Open that url in a browser where you are logged into Discord, and you'll see a menu letting you add the bot to servers you have access to. Add it to the server in question, giving it permission to read messages and read message history.

You need to add this token into GitHub for the Action to work correctly. Checkout this guide to see how you can add the token as a Secret that can be read by the Action. Set the name to SOURCECRED_DISCORD_TOKEN;

If you are running SourceCred locally, set the bot token to the environment variable $SOURCECRED_DISCORD_TOKEN.

You can now load your Discord server. Hooray!

As an added bit of configuration, you can set custom reactionWeights in the reactionWeights section of the Discord config. These allow you to change how much Cred is minted per reaction.

If you want to change the weight for a default reaction, just put the reaction's literal emoji in the config.json, as in "💜": 5 to give the purple heart a weight of 5.

If you want to set a custom weight for a custom emoji, you'll need to get the custom emoji's server id. You can do this by right-clicking on a custom emoji in the server, and clicking "copy link". This will give you a link to the emoji's image on Discord's servers, for example:

https://cdn.discordapp.com/emojis/678399364418502669.png?v=1

The numeric substring is the emoji's ID. You can then specify it in the reaction weights file as $EMOJI_NAME:$EMOJI_ID, as in: "sourcecred:678399364418502669": 10 to give some server's custom SourceCred emoji a weight of 10.

Removing plugins

To deactivate a plugin, just remove it from the bundledPlugins array in the sourcecred.json file. You can also remove its config/plugins/OWNER/NAME directory for good measure.
