Simple WPF HL7 Fluentpath Tester tool

fhirpathtester's Issues

Support authentication when retrieving content from the web

Need a list of locations that support authentication, and provide the ability to associate tokens for them, or the full OAuth flow

Store the history

Persist the history information over sessions, not just in memory during the session.
Could be to an application folder, to a configured fhir server

Does not allow version 4.0.1 in StructureDefinition

It does not like the following in StructureDefinition
<fhirVersion value="4.0.1" />,
but is happy with
<fhirVersion value="4.0.0" />
😄

resolve() FHIRPath function seems not to be supported

Setting to restrict versions of FHIR

If only wanting to work with a specific version of FHIR, include an option to disable the other versions from processing, so that tool only considers a specific version.
Helps stay in STU3 if working in that space, rather than using R4 if the resource was valid there too.

JSON resources in 1.0.2 don't work

Complains with:

STU3 Resource read error:
Could not load file or assembly 'Newtonsoft.Json, Version=9.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

As a workaround, can use https://fhir-formats.github.io/ to convert json to xml

Conversion from JSON to XML doesnt work for STU3 or R4

Also, should change the order of preferred version from STU3, dstu2 then R4, to be decending in precedence. Assume its R4 till you get a version that parses correctly.

Shows Observation.value as type MoneyQuantity

Shows Observation.value as type MoneyQuantity when it is just Quantity.

Errors with = and ~ for date and datetime

The following expressions return results different to what I expect from the docco at http://hl7.org/fhirpath/#operations

@T10:30:31=@T10:30		//False, should be { }
@T10:30:31~@T10:30		//True, should be { }

{ } = ‘a’							// True, should be { }
@2012-01 = @2012					// False, should be { }
@2012-01 ~ @2012					// True, should be False
@2012-01-01T10:30 = @2012-01-01T10:30		//syntax error, should be True
@2012-01-01T10:30 = @2012-01-01T10:31		//syntax error, should be False
@2012-01-01T10:30:31 = @2012-01-01T10:30		//syntax error, should be { }

Better support for invariant testing

When using the Validate button (which essentially checks the fhirpath expression as though it was an invariant) there should be another fhirpath expression that indicates the context at which to perform the check (unless the location of the selection in the resource is used (as that is now possible - its shown in the status line)
