Version 3.3.2

issues resolved

• VisitorMap lets you override hashcode/equals for nodes when used as a key for a map.

Version 3.3.1

issues resolved

• The token list is now mutable - see methods on JavaToken. This caused mild breakage - some fields have become Optional.

Version 3.3.0

issues resolved

• Breaking: TryStmt::tryBlock and EnclosedExpr::inner were optional for no good reason. Now they are required.
• You can now ask a JavaToken for its category, which is useful for examining the token list or doing syntax highlighting or so.
• enum and strictfp can now be used as identifiers on lower Java versions.

Version 3.2.12

issues resolved

Version 3.2.11

issues resolved

• We're up to date with the latest Java 9 module system again.

Version 3.2.10

issues resolved

• Node.replace(old, new) was added, including property-specific X.replaceY(newY) methods

Version 3.2.9

Scrapped due to release problem.

Version 3.2.8

issues resolved

• Added isInnerClass() that checks if a ClassOrInterfaceDeclaration is an inner class (note: this is different from a nested class!)
• @ryan-beckett contributed a huge Eclipse setup guide

Version 3.2.7

issues resolved

• We now recover from some parse errors! Here is an article

Version 3.2.6

issues resolved

• EmptyMemberDeclaration is gone! It was deprecated for a while because it it was in the AST, but doesn't have any meaning in a Java program. EmptyStmt was also deprecated, but that has been reverted. This node does have meaning.

Version 3.2.5

issues resolved

• NodeWithCondition was added on all nodes containing a condition.
• Lots of work on improving lexical preservation.
• If a file was parsed from a file system, you can now get path information etc. from CompilationUnit
• API BREAKING: every node now points to its start and end token. Some of the API has started returning TokenRange instead of Range - you can call toRange to get the old object type. We may still change the naming of some of this code in the following month.

Version 3.2.4

New style changelog, no more issue numbers, but a link: issues resolved and any notable changes:

• the new method Node.removeForced() by removing it, or removing the first parent that is optional. This is different from Node.remove(), remove() only tries to remove the node from the parent and fails if it can't.
• FieldAccessExpr.scope is now a required property. You might find some get()s in your code that are no longer necessary.
• ReferenceType no longer has a type parameter, so every ReferenceType<?> can be replaced by ReferenceType now.

Version 3.2.3

• 907 906 905 903 911 910 909 908 smaller improvements and fixes

Version 3.1.3

Beta: TreeStructureVisitor, and LexicalPreservingPrinter.

A start has been made on source level support. The default level is Java 8. It can be set to Java 9 like this for a parser instance:

private final JavaParser parser = new JavaParser(new ParserConfiguration().setValidator(new Java9Validator()));

and like this for the static parse methods:

JavaParser.getStaticConfiguration().setValidator(new Java9Validator());

• 862 552 "_" is an illegal identifier on source level 9.
• 869 867 109 855 857 smaller improvements and fixes

Version 3.1.2

Beta: TreeStructureVisitor, ConcreteSyntaxModel, and LexicalPreservingPrinter.

• 594 849 831 a validation framework was introduced to inform about problems in the AST without needing to change the grammar, and without requiring parsing code. It is open for extension by users.
• 852 853 826 832 846 839 smaller improvements and fixes

Version 3.1.1

Beta: TreeStructureVisitor, ConcreteSyntaxModel, and LexicalPreservingPrinter.

• 654 124 lexical preservation (printing source code with the same formatting it had when parsing) has been added. Thank you @ftomassetti for a lot of work!
• 554 800 first (big) step towards Java 9 support: JavaParser can read project Jigsaw module definitions.
• 795 786 751 extend the TreeVisitor with more traversal options. Thanks @ryan-beckett!
• 791 GenericListVisitorAdapter has been added which collects its results in a list. Thanks @Gottox!
• 815 798 797 813 clean up Problem text

• 777 805 802 796 790 792 793 781 784 785 783 782 779 357 799 763 smaller improvements and fixes

Version 3.1.0

Beta: TreeStructureVisitor and ConcreteSyntaxModel.

• 705 755 Add the concrete syntax model, which will give you information about the exact syntax a certain nodes matches.

• 777 smaller improvements and fixes

Version 3.1.0-beta.2

This version is a beta because TreeStructureVisitor is not in its definite state yet.

• 762 761 772 merge javaparser-metamodel and javaparser-generator-utils into javaparser-core.
• 766 the ModifierVisitor is now created by a code generator. Its behaviour has been made logical, and may give different results than before.
• 755 ConstructorDeclaration and MethodDeclaration now share a parent: CallableDeclaration
• 687 759 773 769 768 767 765 759 smaller improvements and fixes

Version 3.1.0-beta.1

This version is a beta because there are a lot of new features that may still change.

This version needs a minor version increase because of a backwards compatability issue:

• 719 getJavadoc, getJavadocComment and getComment could return null. Our promise was to return Optional, so that is what they do now.

New:

• 658 718 736 737 we have created a metamodel. It gives information about the structure of the various AST nodes, as if you are introspecting them. You can find it in javaparser-metamodel, the main class is JavaParserMetaModel
• 353 365 visitors are no longer hand made, they are now generated from the metamodel. This should make them 100% reliable. Affected visitors are: GenericVisitorAdapter, EqualsVisitor, VoidVisitorAdapter, VoidVisitor, GenericVisitor, HashCodeVisitor, CloneVisitor.

If you want to generate your own visitors, you can use the VisitorGenerator class from javaparser-core-generators

If you want to reuse the code generation utilities, look at module javaparser-generator-utils - there is a very useful SourceRoot class in there that takes away a lot of file management troubles.

• 538 735 TreeStructureVisitor has been added, which should be considered beta.
• 220 733 717 749 745 750 743 748 666 732 746 734 733 smaller improvements and fixes
