<view> is a ViewDefinition JSON file (some commands also accept a directory of them). Exit codes: 0 success · 1 validation errors, lint errors, test failures, or I/O errors.

Global flags

Section titled “Global flags”
  • --no-color — disable coloured output (also honoured via NO_COLOR).

Commands

Section titled “Commands”

generate

Section titled “generate”

Generate SQL from a ViewDefinition, offline. Emits a PostgreSQL SELECT by default; --dialect duckdb emits DuckDB SQL. With --ddl, emit a CREATE TABLE for the output columns instead.

  • --ddl — emit CREATE TABLE instead of the SELECT.
  • --dialect <d> — for the SELECT: postgres (default) or duckdb (ansi is treated as postgres). For --ddl: ansi (default, spec types), postgres or duckdb. (The flag default is ansi.)
  • --table <name> — table name for --ddl (defaults to the view’s name, else <resource>_view).

run

Section titled “run”

Execute a ViewDefinition and write the rows. Runs against FHIR files with --input (no database) or against PostgreSQL with --db. A directory of ViewDefinitions runs every view in one pass, one output file per view into --out.

  • --input <file|dir|-> — FHIR resources with no database: an NDJSON file, a Bundle, a JSON resource/array, a directory of such files, or - for stdin. Conflicts with --db.
  • --db <url> — PostgreSQL connection URL (or set DATABASE_URL).
  • --output <fmt> — csv (default), ndjson, json (parquet with the Parquet feature).
  • --out <path> — write to this file instead of stdout (a directory when running a directory of views).

NDJSON-in / NDJSON-out for a single view streams resource-by-resource in bounded memory.

validate

Section titled “validate”

Validate a ViewDefinition’s structure against the spec, offline (no package, no database): SQL-safe names, one iteration construct per select, unique column names, consistent unionAll branches.

  • --json — emit findings as machine-readable JSON.
  • --sarif — emit findings as SARIF 2.1.0 (conflicts with --json).

lint

Section titled “lint”

Validate a ViewDefinition’s FHIRPath selectors and generated SQL against a FHIR package, and/or the portable ShareableViewDefinition subset.

  • --package <name> — FHIR package (e.g. hl7.fhir.r4.core). Enables schema-driven selector linting. Optional when --shareable is used.
  • --version <v> — package version. When given, the package is installed if missing; otherwise only an already-present package is used (offline).
  • --shareable — enforce the ShareableViewDefinition FHIRPath subset (FH11).
  • --allow-fn <name> — exempt a custom FHIRPath function from the --shareable allow-list (repeatable).
  • --json / --sarif — machine-readable output (SARIF conflicts with --json).

At least one of --package or --shareable is required.

test

Section titled “test”

Run a SQL-on-FHIR content-test file (or a directory of them) in memory and report pass/fail. The format is {resources, tests:[{title, view, expect|expectCount|expectColumns|expectError}]}. Exits non-zero on any failure.
