The idea is that this provides a way to make common library functions available to Conforma policies, without needing to fetch them down as a policy source. It's kind of experimental currently, but the initial motivation is to avoid the awkwardness around the way we'd like to make lib.result_helper availble to users writing their own policies. If we like the idea, it should be simple enough to extend it to whatever shared library we'd like to provide. There are pros and cons with this idea so let's not commit to it fully just yet. In this commit the only embedded rego is a simple "hello_world" rule. Co-Authored-By: Claude <noreply@anthropic.com>
In the previous commit we focus on reading the embded rego files. Here we're writing it out. Introduces a reusable utility function that writes embedded rego files to the filesystem, following the same directory structure pattern used by external policy sources. Also, call it to write the embedded rego to disk when preparing the policy dir for the Conftest evaluator. The function follows the uniqueDestination pattern where each policy source gets its own subdirectory, with "embedded" acting as the identifier for embedded rego files. We're assuming there's only one embedded directory currently. Co-Authored-By: Claude <noreply@anthropic.com>
This commit includes: - features/embedded_rego.feature: Gherkin acceptance test scenario - acceptance/examples/embedded_rego_test.rego: Test policy using ec_lib.hello_world - acceptance/examples/embedded_rego_config.yaml: Policy configuration The acceptance test verifies that: - Embedded rego functions are available in policy evaluation - The ec_lib.hello_world function works correctly - Policies can import and use data.ec_lib namespace - Output contains expected success messages Co-Authored-By: Claude <noreply@anthropic.com>
