angular_ast 2.0.1

Parser and utilities for AngularDart templates

2.0.1

• Update README.md.

2.0.0

• Support null safety
• Require Dart ^2.14.0

1.0.1

• Update package:analyzer dependency to ^0.40.0.

1.0.0

• Stable release.
• Added support for a reference on <ng-content>.
• toolFriendlyAst{Origin} is always true and is no longer configurable.
• Removed ThrowingAstVisitor.

0.5.11

• Maintenance release to support Dart 2.5 dev.

0.5.10

• New ThrowingTemplateAstVisitor which throws by default in each visit method.

0.5.9

• Errors caused by parsing an invalid micro expression (i.e. *ngFor) are now reported to the registered ExceptionHandler rather than thrown.

0.5.8

• Fixed a type error that occurred when recovering from a missing closing banana ')]'.

0.5.7

• Annotations may now have compound names (for example @foo.bar).

• It is now an error to use @deferred on a <template> tag or combined with a structural (i.e. *ngIf) directive.

• Ignores right-trailing spaces when parsing micro expression let-assignments.

• When parsing a failed micro expression (i.e. *ngFor), avoids a type error.

• vellip is now a recognized char.

• Whitespace inside preformatted text (<pre> tags) is now always preserved.

0.5.6

• Maintenance release to support Dart 2.0 stable.

0.5.5

• Maintenance release for -dev.68.

0.5.4

• Add CloseElementAst complement into ContainerAst.
• Added support for annotations on <template>.
• The whitespace transformer now understands @preserveWhitespace.

0.5.3+3

• Maintenance release for -dev.60.

0.5.3+2

• Maintenance release for -dev.56.

0.5.3+1

• Fixed source span range of AttributeAst which would extend past EOF when recovering from a value with an unclosed quote.

0.5.3

• Exported ParsedAnnotationAst.

• Added ContainerAst.

• Annotations may now be assigned values.

• Added support for annotations on ContainerAst.

• The * micro-syntax now supports leading whitespace.

• Whitespace between <ng-content> and </ng-content> will no longer yield a parsing error.

0.5.2

• The * micro-syntax now supports newlines after an identifier.

0.5.1

• The minimum SDK version is now sdk: ">=2.0.0-dev.46.0 <2.0.0".

• The * micro-syntax now supports binding to the primary input when followed by additional input or let bindings. Previously the micro-syntax supported binding to the primary input only in isolation.

  Example usage enabled by this change.

  Before:

  <template [foo]="expr1" [fooContext]="expr2">
    <div></div>
  </template>
  

  After:

  <div *foo="expr1; context: expr2"></div>
  

0.5.0

• BREAKING CHANGE: We no longer support parsing Dart expressions as part of parsing the template AST. We hope to re-add some support for this by migrating the existing parser in package:angular, but we are likely not to have a stable API for some time.

• BREAKING CHANGE: Deleted ExpressionParserVisitor (related to above).

0.4.4

• Added MinimizeWhitespaceVisitor.

0.4.3+1

• Maintenance release, supporting newer package versions.

0.4.3

• Maintenance release, supporting newer package versions.

0.4.2

• Supports the latest version of quiver.

0.4.1

Bug fixes

• Un-escape HTML characters, such as <, ∑, or ∑, when they appear in text. Note, we do not do any un-escaping when these characters appear inside elements.

0.4.0

First stable release in a while! Going forward we'll be versioning this package normally as needed to support the AngularDart template compiler and analyzer plugin.

New features

• Add RecursiveTemplateAstVisitor, which will visit all AST nodes accessible from the given node.
• Support ngProjectAs decorator on <ng-content>.

Bug fixes

• DesugarVisitor now desugars AST nodes which were the (indirect) children of EmbeddedTemplateAst nodes.

0.4.0-alpha.1

• Update version from 0.4.0-alpha+2 to make it come after 0.4.0-alpha.0 which was published in August 2017.

0.4.0-alpha+2

• Requires analyzer: ^0.31.0-alpha.1.

New Features

• Now supports AnnotationAsts, like @deferred.
• Parse SVG tags as either void or non-void with no error.

Bug fixes

• Fixed sourceSpan calculation to not include the space before the start of an element decorator.
• Sets the origin in all synthetic nodes. Previously, we were missing a few cases.
• Fixed a NPE in DesugarVisitor.

0.4.0-alpha+1

• New code location! angular_ast is now part of the angular mono-repo on https://github.com/angulardart/angular.

Bug fix

• Fixed event name for banana syntax [(name)] from nameChanged to nameChange.

0.2.0

• Add an experimental flag to NgParser (toolFriendlyAstOrigin) which wraps de-sugared AST origins in another synthetic AST that represents the intermediate value (i.e. BananaAst or StarAst)
• Add support for parsing expressions, including de-sugaring pipes. When parsing templates, expression AST objects automatically use the Dart expression parser.

new ExpressionAst.parse('some + dart + expression')

• One exception: The | operator is not respected, as it is used for pipes in AngularDart. Instead, this operator is converted into a special PipeExpression.
• Added TemplateAstVisitor and two examples:
  • HumanizingTemplateAstVisitor
  • IdentityTemplateAstVisitor
• De-sugars the *ngFor-style micro expressions; see micro/*_test.dart.
  • Added attributes as a valid property of EmbeddedTemplateAst

0.1.0
