Release Notes

Version 2.70.0

• Fixed various problems with the HTMLFormatter agent.

Version 2.69.0

• Fixed a bug in the Visitor.visitComponent() method where name collisions could occur with type names.

Version 2.68.0

Version 2.67.0

• Fixed a bug in the Component.validateArgument() function where the function was returning a false boolean rather than throwing an exception.

Version 2.66.0

• Cleaned up confusing code in parsing exceptions.
• Added unit tests for formatting and parsing iterators. The node iterator cannot be formatted into a legal grammatical construct so it does not support formatting.
• Fixed problems with how iterators handle negative slots.

Version 2.65.0

• Fixed a bug in how the src/collections/Catalog constructor sets the type. It was using any type specified in the parameters as the type, but should always be /bali/collections/Catalog so that the visitors work correctly.
• Now exporting the bali.component.validateArgument() and bali.component.normalizedIndex() functions in the main index.js file.

Version 2.64.0

• Fixed incorrect type names for all strings.
• Renamed the Decoder "base2" references to "base02" so that the bases sort correctly.

Version 2.63.0

• Refactored the abstract methods a bit to be more maintainable.
• Added some missing exception cases for some abstract and collection classes.
• Removed the debug argument from Component.componentize(value) method since it is already available from the this pointer for the component.

Version 2.58.0

• Refactored the agent framework to have the abstract pattern classes in the src/abstractions/ directory and the concrete agent implementations in the src/agents/ directory.
• Changed Comparator.compareComponents() to Comparator.ranking().
• Removed the bali.type(object) function from the API in the index.js file since it gets confused with the Component.getType() method.
• Cleaned up the dependencies between types of classes and made sure that the only two circular dependencies (in the Component.toString() and Component.componentize(object) methods) are bound to the class at the end in the top level index.js file.

Version 2.34.0

• Changed the activity rule in the language grammar to code since it is a much better term. Code anthropologists are going to have fun with this one!

Version 2.33.0

• Tightened up the grammar definition for a document so that it forces POSIX text file compliance.
• The Component.toHTML() and Component.toDocument() methods now append the required EOL character to the generated text documents.

Version 2.32.0

• Renamed the action rule to activity in the language grammar to make it a bit more clear.

Version 2.31.0

• Made comments (e.g. /*, */ blocks) into parse tree components so that they are preserved during parse-format round trips.
• Allow notes (e.g. -- This is a note) at the end of any component. The notes too will be preserved during parse-format round trips.

• The constructor for Range now takes a first and last argument instead of an array.
• Added bali/interfaces/Literal and bali/interfaces/Sequential interface support to the Range structure.
• Range.getIterator() will throw an exception if the first and last elements of the range are not integers.

Version 2.26.0

• Added a /bali/interfaces/Discrete interface to the Complex type. This supports the toInteger() method.

• Changed the path 'types' to 'abstractions' to be consistent with the bali naming and to avoid confusion with the bali meta types.

Version 2.24.2

• Another patch to revert the change of Complex.toNumber() returning the magnitude back to returning the real part. Otherwise, negative real numbers come back positive.

Version 2.24.1

• Added missing changes from last release as a patch: Catalog.getValues(...) to Catalog.getAttributes(...) and Catalog.removeValue(...) to Catalog.removeAttribute(...).

Version 2.24.0

• Merged the Composite.[gs]etValue(...) and Structure.[gs]etSubcomponent(...) methods into a new Composite.[gs]etAttribute() method since they implemented the same functionality and were causing confusion with the Element.getValue() method.
• Fixed bug in Complex.toNumber() which was returning only the real part rather than the magnitude.
• Added in the missing reciprocal operation to inversion expressions in the language grammar.

Version 2.23.0

• Updated to the latest versions all dependencies except antr4 which forces ES6 modules after version 4.8.

Version 2.22.2

• Fixed bug in how Catalog constructor handles a type parameter.

Version 2.22.1

• Fixed a bug in Catalog where a $type parameter was not being integrated into the ancestry.

Version 2.22.0

• Renamed the 'receive' message statement to 'retrieve' message to be consistent with the other repository retrieval methods.

Version 2.21.0

• Added an optional ('as' recipient)? part to the 'save' expression grammar rule. The resulting draft citation will be stored in the recipient.

Version 2.20.0

• Added back in the Structure abstract class for the Association, Procedure, and Exception classes to inherit from.

Version 2.19.0

• Changed the Exception.toString() method to include the native stack trace when there is a javascript exception as the cause.
• Updated the document repository related language statement grammar to reflect the latest changes to the repository API and the VM.

Version 2.18.1

• Added many more unit test cases for the Comparator class.
• Made the natural algorithm defined in the Comparator class more general and accurate.
• Fixed several bugs in the Range and Comparator classes when dealing with zero values that were being treated as undefined.
• Added the missing Exception import in the Range class.

Version 2.18.0

• Fixed an HTML formatting bug for Range parameters.
• Found an elegant way to allow a component's parameters to be stored as a Catalog instead of a JavaScript Object without introducing circular dependencies.
• Simplified the language grammar for handle clauses.
• Added a toLiteral() method to the Element and Procedure classes for use by the VM.
• Converted the Complex, Duration, Moment and Range constructors to take a value type that is the same as what is returned from getValue(). This makes duplicating elements more consistent.

Version 2.17.1

• Fixed a bug in how keys are created when converting an object into a catalog.

Version 2.17.0

• Added methods to the Duration class to retrieve parts of the duration.

Version 2.16.0

Version 2.12.3

• Fixed a small bug in the Decoder constructor where an undefined indentation was not handled correctly.

Version 2.12.2

• Fixed a bug in List.removeItems(range) where the items were being removed in order which changes the indexing. They must be removed last to first in the range.

Version 2.12.1

• Fixed some bugs in the getSubcomponent() and the setSubcomponent() methods. The index that was passed in is an element and must be converted to a number for some types of collections.

Version 2.12.0

• Redesigned the Range class and made it an Element instead of a Collection to address the many issues that arose from the previous design.
• Moved the removeAll() method to Collection class since is now implemented by all collections.

Version 2.11.1

• Added a Composite interface that supports getSubcomponent(index) and setSubcomponent(index, subcomponent) methods. The Structure, List and Catalog classes support this interface. This interface is only useful for the compiler and virtual machine.

• Renamed the Composite class to Structure and the abstractions directory to types.
• Added a default implementation to Collection.getItem(index) which uses the iterator to go directly to the requested index.

Version 2.10.0

• Changed all text based expression operators to all uppercase to avoid name collisions with their intrinsic function counterparts. The new operators are IS, MATCHES, NOT, AND, SANS, OR, and XOR.
• Renamed the queue <message> statement to post <message> to avoid a naming collision between the queue keyword and the queue() intrinsic function name. The symantics remain the same.

Version 2.9.0

• Added some missing interfaces.
• Added some missing arguments to the index.tree() function.
• Moved the addItem(item) and addItems(items) methods to the bali.Collection class.
• Fixed an erroneous comment in the bali Catalog.extraction() method.

Version 2.6.0

• Refactored the Iterator class into an abstract class that is now inherited by all iterator classes.

Version 2.5.3

• Updated the generated HTML header to use the latest bali-nebula.net images and icons.

Version 2.5.2

• Fixed bugs in how the Probability class handles booleans passed into its constructor.

Version 2.5.1

• Fixed an error in the path for the favicon.ico file when generating HTML.

Version 2.5.0

• Modified the HTML generated by the HTML formatter class to enhance the readability of different element types.
• Added a link behind each name in a generated HTML document. The link can be used by a browser to retrieve the notarized document associated with the name.

Version 2.4.3

• Added a meta tag to the header for the HTML formatted output that sets the character set to UTF-8.
• Added an explicit link reference to the favicon.

Version 2.4.2

• Having the repository service serve up the static content for the HTML formatter was too slow. It is now served up by a seperate API Gateway instance that connects directly to the S3 bucket holding the content. This required a change to the URI for the static content. It is now https://bali-nebula.net/static/*.

Version 2.4.1

• Fixed error in the location of the static resources for the HTML formatter, the correct path is https://bali-nebula.net/repository/statics/.

Version 2.4.0

• Changed the location of the static resources for the HTML formatter to be in https://bali-nebula.net/statics/.

Version 2.3.3

• Added a check for a configurator directory that does not end with / and fixes it if necessary.

Version 2.3.1

• Changed "Powered By" logo and style sheet for HTML formatting to use the Bali Nebula™ site.

• Removed Component.format() and Component.html() methods that were deprecated.

Version 2.2.4

• Added a missing this pointer to anonymous functions that attempt to reference this.debug.

Version 2.2.3

• Changed font family for HTML style sheet to be Roboto to address formatting issues.

Version 2.2.2

• Deprecated Component.format() and Component.html(), and replaced them with 'Component.toBDN()' and 'Component.toHTML()'.

Version 2.2.1

• Cleaned up some formatting issues with the new HTML formatter class.

Version 2.2.0

• Fixed a bugs in the language grammar for Bali Document Notation™ that allowed components to be used as endpoints in a range instead of restricting them to just element types.
• Added a new HTML utility class and a Component.html(style) method that returns a static web page for the component using the specified link to a CSS style sheet.

Version 2.1.1

• Fixed bugs in the language grammar for Bali Document Notation™ that allowed expressions to be used as values in structural components. The structural components cannot contain expressions since they are declarative and there is no virtual machine to evaluate them.

Version 2.1.0

• Added language grammar support to the Bali Document Notation™ for the symbols ∞, π, φ, and τ, the last being equivalent to the value of 2π per the Tau Manifesto. The new symbols map to the existing values defined for the language:
• ∞: infinity
• π: pi
• φ: phi
• τ: 2 * pi

Version 2.0.0

• This is the first release of v2 of the framework. The framework is ready for general use.
• It's public interfaces should now be stable, though it is far from bug-free.
• From here on out, a minor release (e.g. v2.x) should only add new functionality and bug fixes, it should not break existing code that uses it.
• Each dot release (e.g. v2.x.y) will be for urgent bug fixes.
• There will be v2 releases for the rest of the Bali Nebula™ repositories that depend on the Bali Component Framework™ over the next few months.
