Analyzing with Codyze

Command line mode

When running in command line interface (CLI) mode, Codyze can be used to automatically check a code base against a set of MARK rules. Below are short exemplary calls to start codyze in command line interface mode. ./ refers to the top-level directory of the repository. However, for the Gradle arguments ./ refers to the directory of the project which is codyze-cli.

./gradlew :codyze-cli:run --args="analyze -s <sourcepath> --spec <specpath> -o <outputpath>"
analyze enters command line mode. It will parse all files given by the -s argument. With --spec you can specify the files which contain the policies you want Codyze to verify. The findings are written in SARIF format to the file given by -o.

CI/CD Integration

The CLI mode is a perfect candidate for integration in CI/CD processes, such as GitHub Actions. The following file can be used as an example so set up a compliance check for Java-based applications using GitHub Actions:

name: build

on:
  - push

env:
  CODYZE_VERSION: "2.1.1"

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-java@v3
        with:
          distribution: "temurin"
          java-version: "11"
      - name: Install Codyze
        run: |
          wget "https://github.com/Fraunhofer-AISEC/codyze/releases/download/v${CODYZE_VERSION}/codyze-${CODYZE_VERSION}.zip" && unzip codyze-${CODYZE_VERSION}.zip
      - name: Check compliance
        run: |
          codyze-${CODYZE_VERSION}/bin/codyze -c -o - -m codyze-${CODYZE_VERSION}/mark -s src/main/java

Analysis Example

The repository contains examples which you can use to test Codyze. Below are the commands to call Codyze on these examples.

./gradlew :codyze-cli:run --args="analyze -s ../codyze-specification-languages/coko/coko-dsl/src/test/resources/java/Main.java --spec ../codyze-specification-languages/coko/coko-dsl/src/test/resources/model.codyze.kts --spec ../codyze-specification-languages/coko/coko-dsl/src/test/resources/javaimpl.codyze.kts"

You will see the result printed to the console. The spec files contain a single rule which checks that every change to a database is logged. The sample Java file adheres to the rule so there should be no issues in the result.
