Here, we showcase a reproducible + `R` workflow integrating both deep learning and statistical models + using predator-prey relationships as a case study.

They perform well even with little or no + tuning, and have some theoretical guarantees, especially for sparse + problems {[}@biau:2012;@scornet:etal:2015{]}. These learning + strategies have been used in several contexts, also outside the + field of classification and regression. To perform Bayesian model + selection in the case of intractable likelihoods, the ABC Random + Forests (ABC-RF) strategy of @pudlo:etal:2016 consists in applying + Random Forests on training sets composed of simulations coming from + the Bayesian generative models. The ABC-RF technique is based on an + underlying RF for which the training and prediction phases are + separated. The training phase does not take into account the data to + be predicted. This seems to be suboptimal as in the ABC framework + only one observation is of interest for the prediction. In this + paper, we study tree-based methods that are built to predict a + specific instance in a classification setting. This type of methods + falls within the scope of local (lazy/instance-based/case specific) + classification learning. We review some existing strategies and + propose two new ones.

schema +- **quarto-inspect-document-json-schema.json**: Official document schema + +The type providers are declared with `Schema=` syntax, which validates JSON against the actual JSON Schema specification rather than inferring from samples. + +### Using JSON Schema Mode +```fsharp +// Direct schema validation via type provider +type QuartoProjectProvider = JsonProvider +``` + +This approach: +- Validates against official JSON Schema specification +- Provides compile-time type safety based on schema constraints +- Ensures conformance to Quarto's published interface +- **Compile-time type safety**: Errors caught at compile time, not runtime +- **IntelliSense support**: Full IDE support in VS Code and Visual Studio +- **Schema validation**: Ensures conformance to Quarto specifications +- **Type inference**: F# infers types from JSON structure + +### Project Schema Fields: +- `quarto`: Version information +- `dir`: Project directory path +- `engines`: List of rendering engines (python, r, julia, etc.) +- `config`: Project configuration metadata +- `files`: Input, resource, and config files +- `fileInformation`: Per-document metadata including code cells +- `extensions`: Installed extensions + +### Document Schema Fields: +- `quarto`: Version information +- `engines`: List of rendering engines +- `formats`: Available output formats +- `resources`: Resource files +- `fileInformation`: Document metadata including code cells +- `project`: (Optional) Parent project info if document is in a project + +## Testing + +### Test Categories + +1. **GitHub API Availability** + - Verifies GitHub API connectivity + - Tests repository retrieval + - Handles rate limiting gracefully + +2. **Quarto Installation** + - Checks if Quarto is installed and

Repository Integration** + - Tests with `published-paper-example` repository + - Verifies repository structure + - Skips gracefully if repository not found + +5. **Quarto Inspect Execution** + - Runs actual `quarto inspect` commands + - Validates output schema compliance + - Tests error handling for non-Quarto directories + +### Running Tests + +Tests use Expecto and support various options: + +```bash +# Run all tests +dotnet run + +# Run with specific parallelism +dotnet run -- --parallel 2 + +# List available tests +dotnet run -- --list-tests + +# Run tests matching a pattern +dotnet run

with getcomputo-pub.fsx + +A refactored version of the main script is provided as `getcomputo-pub-refactored.fsx`. It includes: + +- Embedded type providers for compile-time validation +- Improved error handling with schema validation +- Better separation of concerns +- Cleaner JSON parsing using type providers + +To use the refactored version: +```bash +dotnet fsi src/getcomputo-pub-refactored.fsx +``` + +## Schema Files + +The JSON schemas are included in the repository: +- `quarto-inspect-document-json-schema.json`: Document inspection schema +- `quarto-inspect-project-json-schema.json`: Project inspection schema + +These match the official schemas from https://quarto.org/docs/advanced/inspect/. + +## Extending the Type Providers + +To add support for new fields returned by Quarto inspect: + +1. Update the official Quarto JSON Schema files (or wait for Quarto to update them) +2. Rebuild the project - type provider automatically updates to match schema +3. New fields are now available with full IntelliSense support + +The type provider uses JSON Schema mode, so it strictly validates against the schema specification. + +## Error Handling + +The library uses `Result<'T, string>` for error handling, making error cases explicit: + +```fsharp +let validate (jsonStr: string) = + match QuartoClient.validateProjectSchema jsonStr with + | Ok element -> printfn "Valid" + | Error msg -> printfn "Invalid: %s" msg +``` + +## Performance Considerations + +- Type providers are evaluated at compile time, so there's no runtime overhead +- JSON parsing is fast due to FSharp.Data's optimized implementation +- Tests run in parallel (4 workers by default) +- GitHub API calls may be rate-limited (~60 req/hour unauthenticated, ~5000/hour with token) + +## Troubleshooting + +### "Quarto not available" +- Ensure Quarto is installed: `quarto --version` +- Verify Quarto is in PATH +- Tests will skip gracefully if Quarto is not available + +### "GitHub API rate limit exceeded" +- Set GitHub API token: `export API_GITHUB_TOKEN="..."` +- This increases limit from 60 to 5000 requests per hour + +### "Mock repository not found" +- Tests skip gracefully if `published-paper-example` doesn't exist +- This is expected in development environments + +### Schema validation errors +- Check that JSON matches Quarto's official schemas +- Review error message for missing required fields +- Validate raw JSON: `jq . < output.json` diff --git a/src/QuartoInspect/paket.references b/src/QuartoInspect/paket.references new file mode 100644 index 0000000..714d935 ---
