Features

• Determine if a local git repository is InnerSource ready
• Determine if a remote GitHub hosted git repository is InnerSource ready
• Determine if a remote Enterprise GitHub hosted git repository is InnerSource ready
• Customize using declarative json what documentation is required for a repository to be considered InnerSourceReady
• Automatically fixup your local repositories to make them InnerSource ready
• Automatically fixup your remote GitHub hosted repositories to make them InnerSource ready
• Automatically fixup your remote Enterprise GitHub hosted repositories to make them InnerSource ready

Motivation

• Your medium to large sized organization has decided to adopt InnerSource development practices.
• In order for contributors to feel confident contributing to a repository, the repository should demonstrate a minimum level of InnerSource readiness; such as having a CONTRIBUTING.md describing the expectations of the maintainers, or having a README.md with Usage and local development instructions.
• You and your organization have defined what it means for a repository to be InnerSource ready in terms of the expected repository documentation.
• Your organization would like a report on the InnerSource Readiness of its most depended upon repositories.
• You would like to automatically fixup repositories that are not InnerSource ready, so that maintainers know which documents are required and what the most important sections in the documents are for them to fill out to help external contributors.

Usage

The two main operations supported by this library are scanning a repository for InnerSource readiness and fixing up the InnerSource readiness of a repository. First decide if you would like to use the standalone command line interface (CLI) or the Java API. The primary difference between the two interfaces is that you can use multithreading in the Java API to concurrently scan repositories, whereas the CLI requires multiple processes.

• Learn more about using the Java API

Command Line Interface Usage

• Download the CLI Runnable JAR
• Check if your local or remote git repository is InnerSource Ready using the CLI
• Fixup your local or remote git repository so that it is as close to InnerSource Ready as possible using the CLI

Download the Runnable Jar CLI

• Download the latest release version of the runnable jar CLI from either GitHub Packages or Maven Central.
• Rename the downloaded runnable jar to innersource.jar for convenience. The examples below will assume this filename.

NOTE: Java 1.8+ must be installed in order to execute the runnable jar and follow the examples below.

Use CLI to Generate InnerSource Readiness Report

If your repository is checked out locally:

java -jar innersource.jar -c REPORT -r /path/to/checked/out/repo

If your repository is hosted on GitHub (public or enterprise):

java -jar innersource.jar -c REPORT -r https://github.yourorg.com/repo-org-name/repo-name -a yourGithubAccessToken

After running the report command, you should see a json report output similar to the following:

The top level property isRepositoryInnerSourceReady will be true if the scanned repository is considered InnerSource Ready, and false otherwise.

It's handy to pipe the output of the report command to jq to extract just the information you care about.

Checking if your repository is innersource ready thus becomes:

java -jar innersource.jar -c=REPORT -r=https://github.com/your/repo -a=your-gh-auth-token | jq .isRepositoryInnerSourceReady

Which should return the boolean true or false.

There are quite a few additional details included in the report, so you can zoom in on exactly what was missing from the repository.

For example, if your repository is not InnerSource ready you can see which files were evaluated and which file checks were not satisfied with the following command:

java -jar innersource.jar -c=REPORT -r=https://github.com/your/repo -a=your-gh-auth-token | jq '[.fileRequirementReports | .[] | select(.isFileRequirementSatisfied == false) | {optionEvaluated, fileChecksReports: .fileChecksReports | .[] | del(.fileChecksEvaluated) | del(.isFileChecksSatisfied) | del(.fileCheckReports[] | select(.isFileCheckSatisfied == true))}]'

The Default InnerSource Readiness Specification states that a repository is considered InnerSource Ready if the following files are present, and not empty. (NOTE: The files do not actually have to appear in the exact locations as shown; so long as the file is located in either the repo root /, the GitHub metadata directory /.github or the docs directory /docs, the file requirement will be satisfied) Some files have additional requirements such as the README requiring a Title heading, or the issue template expecting yaml front matter. The exact requirements for each file is explained below and in the json spec linked above.

/repo
|-- /.github
|   |-- /ISSUE_TEMPLATE
|   |   `-- someIssueTemplate.md
|   |-- /PULL_REQUEST_TEMPLATE
|   |   `-- somePullRequestTemplate.md
|   `-- CODEOWNERS
|-- CONTRIBUTING.md
|-- CODE_OF_CONDUCT.md
|-- LICENSE
|-- SUPPORT.md
`-- README.md

The default InnerSource Readiness specification can be customized or overridden. See the Customize InnerSource Readiness Specification Configuration.

Use CLI to Fixup Repositories

If your repository is checked out locally:

java -jar innersource.jar -c FIXUP -r /path/to/checked/out/repo

If your repository is hosted on GitHub (public or enterprise):

java -jar innersource.jar -c FIXUP -r https://github.yourorg.com/repo-org-name/repo-name -a yourGithubAccessToken

The Default Fixup Templates for the FIXUP command will create the following files with predefined content if the file does not exist or is empty:

• /README.md
• /CONTRIBUTING.md
• /CODE_OF_CONDUCT.md
• /SUPPORT.md
• /.github/CODEOWNERS

The default Fixup File Templates can be customized or overridden. See the Customize Fixup File Templates Configuration.

Java API Usage

• Install Dependencies
• Check if your local or remote git repository is InnerSource Ready using the Java API
• Fixup your local or remote git repository so that it is as close to InnerSource Ready as possible using the Java API

Install Dependencies

Use Java API to Generate InnerSource Readiness Report

If your repository is checked out locally:

InnerSourceReadinessReport report = 
  InnerSourceReadinessReportCommand.create(
    LocalRepositoryFilePath.of(Paths.get("/your/local/git/repo/root"))
  )
  .build()
  .call();        

If your repository is hosted on GitHub (public or enterprise):

Add the following optional dependency to your classpath:

<!-- https://mvnrepository.com/artifact/org.kohsuke/github-api -->
<dependency>
    <groupId>org.kohsuke</groupId>
    <artifactId>github-api</artifactId>
    <version>1.122</version>
</dependency>

Create an instance of GitHubRepositoryPath by configuring a GHRepository instance using your GitHub server and credentials:

GitHub gh = new GitHubBuilder()
    .withOAuthToken("yourGithubAccessToken")
    .withEndpoint("https://github.yourorg.com/api/v3")
    .build();

GHRepository repository = gh.getRepository("repo-org-name/repo-name");

InnerSourceReadinessReport report =
  InnerSourceReadinessReportCommand.create(
    GitHubRepositoryPath.of(repository)
  )
  .build()
  .call();     

After running the report command you can inspect the InnerSourceReadinessReport object to find out if your repository is InnerSource Ready or determine which required files were or were not present.

boolean isReadyAccordingToSpec = report.isRepositoryInnerSourceReady();

By default, the InnerSourceReadinessReportCommand uses the InnerSourceReadinessSpecification.PUBLIC_GITHUB_DEFAULT specification which considers repositories InnerSource Ready only if they have a certain set of files, and the files satisfy a set of predefined file checks.

The default specification can be customized or overridden. See the Customize InnerSource Readiness Specification Configuration.

Did the scanned repository contain a README file containing all the expected headers?

FileRequirement readmeFileRequirementPassedToSpec = ...;

boolean foundReadme = report.isFileRequirementSatisfied(
      readmeFileRequirementPassedToSpec
);

Did any of the scanned README files contain a USAGE heading?

FileCheck usageHeadingFileCheckPassedToSpec = ...;

boolean foundReadmeWithUsageHeading = report.getOnlyFileRequirementReportFor(
      readmeFileRequirementPassedToSpec
    )
    .get() // unwrap the optional
    .getFileChecksReports() // if multiple README files were found, each will be assessed for the specified file checks
    .stream()
    .anyMatch(checksReport -> 
        checksReport.isFileCheckSatisfied(usageHeadingFileCheckPassedToSpec)
    );

See the javadoc for additional details that you can obtain from the report object.

Use Java API to Fixup Repositories

List<RepositoryFilePath> fixedFiles =
  InnerSourceReadinessFixupCommand.create(
    LocalRepositoryFilePath.of(Paths.get("/your/local/git/repo/root"))
  )
  .build()
  .call();        

By default, the InnerSourceReadinessFixupCommand uses the FixupFileTemplates.PUBLIC_GITHUB_DEFAULT set of templates which will create a set of default files with predefined content.

The Fixup File Templates can be customized or additional templates defined. See the Customize Fixup File Templates Configuration.

Any files that are created or modified are returned as a result of running this command.

This JSON specification states that for a repository to be considered InnerSource ready, there must be a README markdown file containing a USAGE section heading, and a Local Development section heading (alternately titled Local Dev) as well as a non-empty PULL_REQUEST_TEMPLATE file, or a non-empty PULL_REQUEST_TEMPLATE directory either located in the repository root directory or the /.github or /docs directories.

NOTE: You can use your JSON spec via the Java API's InnerSourceReadinessSpecification.fromJson() static factory method.

Supply this JSON file to either the REPORT or FIXUP command with the -s, --spec parameter:

java -jar innersource.jar -c REPORT -s innersource.spec.json -r https://github.yourorg.com/repo-org-name/repo-name -a yourGithubAccessToken

java -jar innersource.jar -c FIXUP -s innersource.spec.json -r https://github.yourorg.com/repo-org-name/repo-name -a yourGithubAccessToken

Customize Specification Using Java API

InnerSourceReadinessSpecification specification = 
  InnerSourceReadinessSpecification.create(
    "NameOfYourSpecification",
    RepositoryRequirements.create(
        DirectoriesToSearch.create(
            "/", // root is git workspace root   
            "/docs",  
            "/.github"
        ),
        FileRequirement.create(
          FileToFind.create("/README.md"),
          FileChecks.create(
            FileCheck.fileExists(),
            FileCheck.fileNotEmpty(),
            FileCheck.markdownFileWithHeading(
                "USAGE", // heading text to find
                Sets.newHashSet(), // acceptable synonyms
                false, // case sensitive
                true // satisfied if section is empty?
            ),
            FileCheck.markdownFileWithHeading(
                "Local Development",
                Sets.newHashSet("Local Dev"),
                false,
                true
            )        
          )
        ),
        FileRequirement.oneOf(
          FileRequirementOption.create(
            FileToFind.create("/.github/PULL_REQUEST_TEMPLATE.md"),
            FileChecks.create(
                FileCheck.fileExists(), 
                FileCheck.fileNotEmpty()
            )
          ),
          FileRequirementOption.create(
            FileToFind.create("/.github/PULL_REQUEST_TEMPLATE/"),
            FileChecks.create(
                FileCheck.directoryExists(),
                FileCheck.directoryNotEmpty()
            )
          )
        )        
    )
);

The specification above states that for a repository to be considered InnerSource ready, there should be a non-empty README file containing 2 headings USAGE and Local Development (Local Dev is an acceptable synonym) as well as a non-empty PULL_REQUEST_TEMPLATE file or non-empty PULL_REQUEST_TEMPLATE directory, located either in the repository root directory, the /docs directory or the /.github directory.

Once created, you can supply this custom specification to either of the command builders:

Create a Report Command with a custom InnerSource Readiness Specification:

InnerSourceReadinessReport report =
        InnerSourceReadinessReportCommand.create(
            LocalRepositoryFilePath.of(Paths.get("/your/local/git/repo/root"))
        )
        .specification(specification)
        .build()
        .call();        

Create a Fixup Command with a custom InnerSource Readiness Specification:

List<RepositoryFilePath> fixedFiles =
  InnerSourceReadinessFixupCommand.create(
    LocalRepositoryFilePath.of(Paths.get("/your/local/git/repo/root"))
  )
  .specification(specification)
  .build()
  .call();        

Customize Fixup File Templates

• Using CLI
• Using Java API

Customize Fixup File Templates Using CLI

Create a json file (we'll use the filename templates.spec.json) containing empty file templates to use when running the fixup command. These file templates will be used to create new files for any files required by the specification but not found in the target repository.

{
  "emptyFileTemplates": {
    "/README.md": "Default README file contents."
  }
}

NOTE: The key for the empty file template should exactly match the expectedFilePath string value defined in the specification json.

Supply this JSON file to the FIXUP command with the -t, --templates parameter:

If your repository is checked out locally:

java -jar innersource.jar -c FIXUP -r /path/to/checked/out/repo -t templates.spec.json

If your repository is hosted on GitHub (public or enterprise):

java -jar innersource.jar -c FIXUP -r https://github.yourorg.com/repo-org-name/repo-name -a yourGithubAccessToken -t templates.spec.json

Customize Fixup File Templates Using Java API

List<RepositoryFilePath> fixedFiles =
  InnerSourceReadinessFixupCommand.create(
    LocalRepositoryFilePath.of(Paths.get("/your/local/git/repo/root"))
  )
  .specification(specification)
  .fileTemplates(
    FixupFileTemplates.from(
      ImmutableMap.of(
        "/README.md", // should match path in spec 
        "README contents, when README is not found"
      )
    )
  )
  .build()
  .call();        

Customize Logging Service

• Using CLI
• Using Java API

Customize Logging Using CLI

There is no way to customize the logging service using the Command Line Interface. If you need to have the log output redirected or suppressed, please consult your terminal's documentation for redirecting the standard output and standard error streams to either a file or to a null location, such as /dev/null.

Customize Logging Using Java API

The Report and Fixup command builders can also be supplied with alternate LoggingService implementations. The default will write logs to the standard output and standard error stream. In production, you will probably want to supply a different consumer to write to a log file. The library comes with a Slf4j api implementation, however you may supply your own instance of the LoggingService interface as well.

Suppress logging during execution of the Fixup Command:

List<RepositoryFilePath> fixedFiles =
  InnerSourceReadinessFixupCommand.create(
    LocalRepositoryFilePath.of(Paths.get("/your/local/git/repo/root"))
  )
  .loggingService(NoopLoggingService.INSTANCE)
  .build()
  .call();        

Configure logging to the SLF4J API during execution of the Report Command:

InnerSourceReadinessReport report =
        InnerSourceReadinessReportCommand.create(
            LocalRepositoryFilePath.of(Paths.get("/your/local/git/repo/root"))
        )
        .loggingService(Slf4jLoggingService.INSTANCE)
        .build()
        .call();        

Local Development

Build

To build and run the unit tests:

mvn clean verify

Mutation Testing

In addition to unit tests, this library also performs mutation testing using PITest. After running the verify goal, inspect the generated report at /target/pit-reports/<date>/index.html. Mutation testing provides an indication of how effective your unit testing by modifying your source code and attempting to re-run your test suite. If your tests do not fail, it implies that the mutated source code is not sufficiently tested by your unit test suite. Use the mutation coverage report to guide your unit testing efforts.
