fhir-codegen-cli [options]
Options:
--fhir-spec-directory <fhir-spec-directory> The full path to the directory where FHIR
specifications are downloaded and cached.
--output-path <output-path> File or directory to write output.
--verbose Show verbose output.
--offline-mode Offline mode .
(will not download missing specs)
--language <language> Name of the language to export.
(default: Info|TypeScript|CSharpBasic)
--export-keys <export-keys> '|' separated list of items to export.
(not present to export everything)
--load-r2 <load-r2> If FHIR R2 should be loaded, which version.
(e.g., 1.0.2 or latest)
--load-r3 <load-r3> If FHIR R3 should be loaded, which version.
(e.g., 3.0.2 or latest)
--load-r4 <load-r4> If FHIR R4 should be loaded, which version.
(e.g., 4.0.1 or latest).
--load-r5 <load-r5> If FHIR R5 should be loaded, which version.
(e.g., 4.4.0 or latest)
--language-options <language-options> Language specific options, see documentation
for more details.
(e.g., CSharpBasic|namespace=myorg.fhir)
--official-expansions-only True to restrict value-sets exported to only
official expansions.
(default: false)
--fhir-server-url <fhir-server-url> FHIR Server URL to pull a CapabilityStatement
(or Conformance) from. Only supports
application/fhir+json.
--include-experimental If the output should include structures
marked experimental.
(default: false)
--export-types Which FHIR classes types to export:
primitive|complex|resource|interaction|enum.
(default: all types)
--version Show version information
-?, -h, --help Show help and usage information
-
Download and parse FHIR R4 (latest published version) into ./fhir, then build a TypeScript file in the current directory
fhir-codegen-cli --load-r4 latest --fhir-spec-directory ./fhir --language TypeScript --output-path ./R4.ts
-
Download and parse FHIR R4 (latest published version) into ./fhir, then build a TypeScript file in the current directory, restricted to just the Resources: Patient, Encounter, and Observation
fhir-codegen-cli --load-r4 latest --fhir-spec-directory ./fhir --language TypeScript --output-path ./R4.ts --export-keys Patient|Encounter|Observation
-
Download and parse the latest published version of each FHIR release into ./fhir, then build a C# file for each in ./cs
fhir-codegen-cli --load-r2 latest --load-r3 latest --load-r4 latest --load-r5 latest --fhir-spec-directory ./fhir --language CSharpBasic --output-path ./cs
-
Download and parse FHIR R4 (latest published version) into ./fhir, then build a C# file in the current directory using the namespace: MyOrg.MyProject.Fhir
fhir-codegen-cli --load-r4 latest --fhir-spec-directory ./fhir --language CSharpBasic --output-path ./cs/R4.cs --language-options CSharpBasic|namespace=MyOrg.MyProject.Fhir
-
Info
Basic text output of a version of FHIR for information and testing.
-
CSharpBasic
Basic C# language bindings, useful for prototyping and small projects. Exported classes are able to serialize to and parse from FHIR JSON.
-
TypeScript
Basic TypeScript bindings, useful for prototyping and small projects. Exported classes are able to serialize to and parse from FHIR JSON.
-
CSharpFirely
Export base C# classes needed for the Firely-maintained C# API (FHIR-Net-API).
-
OpenAPI EXPERIMENTAL
Export an OpenAPI 2 or 3 JSON version of the standard.
Running dotnet run -p src/fhir-codegen-test-cli/fhir-codegen-test-cli.csproj launches a full build and test.
It will generate updated CSharpBasic and TypeScript files for FHIR Versions DSTU2, STU3, R4, and R5 (May 2020). It will then run each through a build process (requires dotnet for C# and tsc for TypeScript) to validate there are no syntax errors in any of the generated files.
Note that this test takes several minutes to run.
fhir-codegen-test-cli:
The FHIR CodeGen Test CLI.
Usage:
fhir-codegen-test-cli [options]
Options:
--repo-root-path <repo-root-path> The path to the repository root (if not CWD).
--verbose True to display all output
(default: false)
--fixed-format-statistics True to output *only* test run statistics:
#run[tab]#passed[tab]#failed[tab]#skipped
(default: false)
--errors-to-std-error True to write errors to stderr instead of stdout.
(default: False)
--version Show version information
-?, -h, --help Show help and usage information
The generated directory has static outputs for each of the supported versions of FHIR, in each of the supported languages.
The system is designed to allow developers to add additional languages to be exported. For more information, please see the documentation.
