Refactor loadGraph out of exportGraph (#1113)
This pulls the logic for loading a SourceCred graph from disk out
`cli/exportGraph` and into `analysis/loadGraph`. The rationale is that
`exportGraph` is not the only command that wants the ability to load a
graph from the analysis adapters.

The new command has a clean return signature that reports whether the
load was successful, or failed because the graph wasn't loaded, or
failed due to an error in plugin code.

Testing of the loading logic has been moved to `loadGraph.test`, and the
CLI has been refactored so that the loadGraph method is dependency
injected. This allows for (IMO) cleaner testing of the CLI method.

There is one (deliberate) change in behavior, which is that the command no
longer throws an error if no plugins are included; instead it will just
export an empty graph. I don't have a strong preference between the two
behaviors; changing it was just more convenient.

Test plan: New unit tests have been added, and tests of the cli command
have been re-written. As a sanity check, I've verified that the
following sequence still works:

```
$ yarn backend
$ node bin/sourcecred.js load sourcecred/pm
$ node bin/sourcecred.js export-graph sourcecred/pm
```

Nearly perfect code coverage is maintained. One line is uncovered, and
it's the line that injects in the actual graph loading behavior.

SourceCred

Build Status Discourse topics Discord

SourceCred creates reputation networks for open-source projects. Any open-source project can create its own cred, which is a reputational metric showing how much credit contributors deserve for helping the project. To compute cred, we organize a projects contributions into a graph, whose edges connect contributions to each other and to contributors. We then run PageRank on that graph.

To learn more about SourceCreds vision and values, please check out our website and our forum. One good forum post to start with is A Gentle Introduction to Cred.

For an example of SourceCred in action, you can see SourceCreds own prototype cred attribution.

Current Status

We have a prototype that can generate a cred attribution based on GitHub interactions (issues, pull requests, comments, references, etc.). Were working on adding more information to the prototype, such as tracking modifications to individual files, source-code analysis, GitHub reactions, and more.

Running the Prototype

If youd like to try it out, you can run a local copy of SourceCred as follows. First, make sure that you have the following dependencies:

Then, run the following commands to clone and build SourceCred:

git clone https://github.com/sourcecred/sourcecred.git
cd sourcecred
yarn install
yarn backend
export SOURCECRED_GITHUB_TOKEN=YOUR_GITHUB_TOKEN
node bin/sourcecred.js load REPO_OWNER/REPO_NAME
# this loads sourcecred data for a particular repository
# it can take a few mins to run and will exit when finished
yarn start
# then navigate to localhost:8080 in your browser

For example, if you wanted to look at cred for ipfs/js-ipfs, you could run:

$ export SOURCECRED_GITHUB_TOKEN=0000000000000000000000000000000000000000
$ node bin/sourcecred.js load ipfs/js-ipfs

replacing the big string of zeros with your actual token.

You can also combine data from multiple repositories into a single graph. To do so, pass multiple repositories to the load command, and specify an “output name” for the repository. For instance, the invocation

node bin/sourcecred.js load ipfs/js-ipfs ipfs/go-ipfs --output ipfs/meta-ipfs

will create a graph called ipfs/meta-ipfs in the cred explorer, containing the combined contents of the js-ipfs and go-ipfs repositories.

Early Adopters

Were looking for projects who want to be early adopters of SourceCred! If youre a maintainer of an open-source project and would like to start using SourceCred, please reach out to us on our Discord or our forum.

Contributing

Wed love to accept your contributions! You can reach out to us by posting on our forum, or chatting with us on Discord. We'd be happy to help you get started and show you around the codebase. Please also take a look at our contributing guide.

If youre looking for a place to start, weve tagged some good first issues.
