[0.7.0]

[0.6.1]

• Update to dart 2.16.0
• Update to fhir 0.6.1
• Added import sorter
• Changed a bunch of .length == 0 to .isEmpty

[0.6.0]

• Updated to 0.6.0 to follow the rest of the FHIR packages
• Still needs some work for some of the tests
• prettyPrint is now called verbosePrint because, well, it is
• There is also a new PrettyPrint which is more what I wanted when I first created verbosePrint (it looks kind of like reverse polish notation)
• Some of the spacing, especially for the commaParser, is likely to change for PrettyPrint, but I think it's close enough to go ahead and publish

[0.5.0-21]

• Trying to improve $this
• fixed .select (maybe)
• Better handling quantity, including equality
• Limited support for .extension()
• Support extension on primitive types
• Pretty print option (extensive, but may be helpful to evaluate lexing)

[0.5.0-20]

• Multiple bug fixes and improvements again by Tilo
• Ported the FHIRPath test suite from XML to Dart
• More tests enabled & fixed
• Fixed .all(XXX), .intersect()
• Fixes % to variables, is for DateTime, comparisons for quantities
• Fixed bug when using $this in nested iifs

[0.5.0-19]

• Forgot to update to newest fhir package

[0.5.0-18]

• Allow pre-parsing of the AST for repeat use later. Boosts performance.
• Allow lazy evaluation of passed-in variables (by passing in a function, instead of an actual value)
• Numerous bug-fixes to iif, operator precedence, unary operators
• Beefed up the test-suite to show that it really works

[0.5.0-17]

• [Breaking] Decoupled %context from %resource.
  • Important for item-level expressions on QuestionnaireResponse, where %context is the item, but %resource is the overall QuestionnaireResponse
• Enable the UI to accept arbitrary JSON, rather than only FHIR Resources

[0.5.0-16]

• Update fhir version

[0.5.0-15]

• Added some comments

[0.5.0-14]

• Update fhir version
• Accepted Tilo's PR

[0.5.0-13]

• Update fhir version

[0.5.0-12]

• Update fhir version

[0.5.0-11]

• Updated dependencies

[0.5.0-10]

• Added Calendar/Duration Quantities
• Added basic DateTime arithmetic

[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
