fhir_path 0.5.0-9

FHIRPath navigation and extraction language implemented in pure Dart to be used with base FHIR packages.

[0.5.0-9]

• More robust error-handling

  • Define two exception types to indicate errors in the expression and errors at evaluation time.
  • Added check for non-existent variables
  • Added check for undefined functions
  • Added check for running substring on a non-string

• Support for hasValue()

• Support for answers()

• Support for not()

• Fix: identifier matching could return arbitrary results

• Better UI

  • Monospace font
  • Choose output format: JSON or YAML
  • Copy results to clipboard

• Updated dependencies

[0.5.0-8]

• Fix: Add ability to escape " characters
• Fix: Add error handling, which directly displays the issue if a FHIRPath is unable to be parsed
• Note that smart quotes such as “ and ” behave differently on iOS (PWA) than they do the following platforms: iOS (native), Android (native/pwa), and desktop web formats (including PC, Chromebook, iOS). This has not been tested on native Linux, iOS, or Windows yet. Specifically, including either “ or ” in your FHIRPath may cause the iOS PWA to inadvertenly include that text into its logic, potentially resulting in a Stack Overflow error.
• I believe the above errors are caused by the Quantity Lexer. I'm removing it temporarily until I can more formally test Quantities (and add in the proper implementations of Quantities parsers)

[0.5.0-7]

• Updated to Dart 2.14.0

[0.5.0-6]

• Easier ability to create simple server for testing
• Iif now included (previously included too, but now removed from the Readme ToDo list)

[0.5.0-5]

• Fine, all polymorphic items work
• Added full list of polymorphic prefixes (current list for R4)

[0.5.0-4]

• For polymorphic items, it was allowing searches with only parts of identifiers, now fixed, so only works with "value" polymorphic items

[0.5.0-3]

• Refactored how I managed 'where' & 'exists'
• Now allows 'contains' on list.length > 1 (this is contrary to the official spec)
• Removed passing 'where' to any functions. Now handles it within the 'where' and 'exists' functions themselves, instead of requiring other functions to handle it

[0.5.0-2]

• Update from Tilo to allow polymorphisms
• Updated to allow Unary '+' and '-' operators

[0.5.0-1]

• first version of package, but numbered to be in sync with other packages
• Needs a lot of readme updates
