Fixed inner class def to allow named class defs as statements synchronized requires compound not simple statement add [] after builtInType DOT class in primaryExpression "const" is reserved but not valid..removed from modifiers Version 1.12 (Feb 2, 1999) Changed LITERAL_xxx to xxx in tree grammar. Updated java.g to use tokens {...} now for 2.6.0 (new feature). Version 1.13 (Apr 23, 1999) Didn't have (stat)? for else clause in tree parser. Didn't gen ASTs for interface extends. Updated tree parser too. Updated to 2.6.0. Version 1.14 (Jun 20, 1999) Allowed final/abstract on local classes. Removed local interfaces from methods Put instanceof precedence where it belongs...in relationalExpr It also had expr not type as arg; fixed it. Missing ! on SEMI in classBlock fixed: (expr) + "string" was parsed incorrectly (+ as unary plus). fixed: didn't like Object[].class in parser or tree parser Version 1.15 (Jun 26, 1999) Screwed up rule with instanceof in it. :( Fixed. Tree parser didn't like (expr).something; fixed. Allowed multiple inheritance in tree grammar. oops. Version 1.16 (August 22, 1999) Extending an interface built a wacky tree: had extra EXTENDS. Tree grammar didn't allow multiple superinterfaces. Tree grammar didn't allow empty var initializer: {} Version 1.17 (October 12, 1999) ESC lexer rule allowed 399 max not 377 max. java.tree.g didn't handle the expression of synchronized statements. Version 1.18 (August 12, 2001) Terence updated to Java 2 Version 1.3 by observing/combining work of Allan Jacobs and Steve Messick. Handles 1.3 src. Summary: o primary didn't include boolean.class kind of thing o constructor calls parsed explicitly now: see explicitConstructorInvocation o add strictfp modifier o missing objBlock after new expression in tree grammar o merged local class definition alternatives, moved after declaration o fixed problem with ClassName.super.field o reordered some alternatives to make things more efficient o long and double constants were not differentiated from int/float o whitespace rule was inefficient: matched only one char o add an examples directory with some nasty 1.3 cases o made Main.java use buffered IO and a Reader for Unicode support o supports UNICODE? Using Unicode charVocabulary makes code file big, but only in the bitsets at the end. I need to make ANTLR generate unicode bitsets more efficiently. Version 1.19 (April 25, 2002) Terence added in nice fixes by John Pybus concerning floating constants and problems with super() calls. John did a nice reorg of the primary/postfix expression stuff to read better and makes f.g.super() parse properly (it was METHOD_CALL not a SUPER_CTOR_CALL). Also: o "finally" clause was a root...made it a child of "try" o Added stuff for asserts too for Java 1.4, but *commented out* as it is not backward compatible. Version 1.20 (October 27, 2002) Terence ended up reorging John Pybus' stuff to remove some nondeterminisms and some syntactic predicates. Note that the grammar is stricter now; e.g., this(...) must be the first statement. Trinary ?: operator wasn't working as array name: (isBig ? bigDigits : digits)[i]; Checked parser/tree parser on source for Resin-2.0.5, jive-2.1.1, jdk 1.3.1, Lucene, antlr 2.7.2a4, and the 110k-line jGuru server source. Version 1.21 (October 17, 2003) Fixed lots of problems including: Ray Waldin: add typeDefinition to interfaceBlock in java.tree.g He found a problem/fix with floating point that start with 0 Ray also fixed problem that (int.class) was not recognized. Thorsten van Ellen noticed that \n are allowed incorrectly in strings. TJP fixed CHAR_LITERAL analogously. Version 1.21.2 (March, 2003) Changes by Matt Quail to support generics (as per JDK1.5/JSR14) Notes: o We only allow the "extends" keyword and not the "implements" keyword, since that's what JSR14 seems to imply. o Thanks to Monty Zukowski for his help on the antlr-interest mail list. o Thanks to Alan Eliasen for testing the grammar over his Fink source base Version 1.22 (July, 2004) Changes by Michael Studman to support Java 1.5 language extensions Notes: o Added support for annotations types o Finished off Matt Quail's generics enhancements to support bound type arguments o Added support for new for statement syntax o Added support for static import syntax o Added support for enum types o Tested against JDK 1.5 source base and source base of jdigraph project o Thanks to Matt Quail for doing the hard part by doing most of the generics work Version 1.22.1 (July 28, 2004) Bug/omission fixes for Java 1.5 language support o Fixed tree structure bug with classOrInterface - thanks to Pieter Vangorpto for spotting this o Fixed bug where incorrect handling of SR and BSR tokens would cause type parameters to be recognised as type arguments. o Enabled type parameters on constructors, annotations on enum constants and package definitions o Fixed problems when parsing if ((char.class.equals(c))) {} - solution by Matt Quail at Cenqua Version 1.22.2 (July 28, 2004) Slight refactoring of Java 1.5 language support o Refactored for/"foreach" productions so that original literal "for" literal is still used but the for sub-clauses vary by token type o Fixed bug where type parameter was not included in generic constructor's branch of AST Version 1.22.3 (August 26, 2004) Bug fixes as identified by Michael Stahl; clean up of tabs/spaces and other refactorings o Fixed typeParameters omission in identPrimary and newStatement o Replaced GT reconcilliation code with simple semantic predicate o Adapted enum/assert keyword checking support from Michael Stahl's java15 grammar o Refactored typeDefinition production and field productions to reduce duplication Version 1.22.4 (October 21, 2004) Small bux fixes o Added typeArguments to explicitConstructorInvocation, e.g. new <String>MyParameterised() o Added typeArguments to postfixExpression productions for anonymous inner class super constructor invocation, e.g. new Outer().<String>super() o Fixed bug in array declarations identified by Geoff Roy Version 1.22.4.g.1 o I have taken java.g for Java1.5 from Michael Studman (1.22.4) and have applied the groovy.diff from java.g (1.22) by John Rose back onto the new root (1.22.4) - Jeremy Rayner (Jan 2005) o for a map of the task see... http://groovy.javanicus.com/java-g.png Version 1.22.4.g.2 o mkempf, rkleeb, Dec 2007 o fixed various rules so that they call the correct Create Method to make sure that the line information are correct This grammar is in the PUBLIC DOMAIN

### appendedBlock

    public final void appendedBlock(antlr.collections.AST callee)

  An appended block follows any expression. If the expression is not a method call, it is given an empty argument list.

### argList

    public final void argList()

### argument

    public final byte argument()

  A single argument in (...) or [...]. Corresponds to to a method or closure parameter. May be labeled. May be modified by the spread operator '*' ('*:' for keywords).

### argumentLabel

    public final void argumentLabel()

  A label for an argument is of the form a:b, 'a':b, "a":b, (a):b, etc.. The labels in (a:b), ('a':b), and ("a":b) are in all ways equivalent, except that the quotes allow more spellings. Equivalent dynamically computed labels are (('a'):b) and ("${'a'}":b) but not ((a):b) or "$a":b, since the latter cases evaluate (a) as a normal identifier. Bottom line: If you want a truly variable label, use parens and say ((a):b).

### argumentLabelStart

    public final void argumentLabelStart()

  For lookahead only. Fast approximate parse of an argumentLabel followed by a colon.

### assignmentExpression

    public final void assignmentExpression(int lc_stmt)

### assignmentLessExpression

    public final void assignmentLessExpression()

  In Java, "if", "while", and "for" statements can take random, non-braced statements as their bodies. Support this practice, even though it isn't very Groovy.

### balancedBrackets

    public final void balancedBrackets()

  Fast lookahead across balanced brackets of all sorts.

### balancedTokens

    public final void balancedTokens()

  lookahead predicate for usage of generics in methods as parameter for the method. Example: static <T> T foo(){} <T> must be first after the modifier. This rule allows more and does no exact match, but it is only a lookahead, not the real rule.

### blockBody

    public final void blockBody(int prevToken)

### branchStatement

    public final void branchStatement()

  In Groovy, return, break, continue, throw, and assert can be used in a parenthesized expression context. Example: println (x || (return)); println assert x, "won't print a false value!" If an optional expression is missing, its value is void (this coerces to null when a value is required).

### buildTokenTypeASTClassMap

    protected void buildTokenTypeASTClassMap()

### builtInType

    public final void builtInType()

### builtInTypeArraySpec

    public final void builtInTypeArraySpec(boolean addImagNode)

### builtInTypeSpec

    public final void builtInTypeSpec(boolean addImagNode)

### caseSList

    public final void caseSList()

### casesGroup

    public final void casesGroup()

### checkSuspiciousExpressionStatement

    public final void checkSuspiciousExpressionStatement(int prevToken)

  If two statements are separated by newline (not SEMI), the second had better not look like the latter half of an expression. If it does, issue a warning.

  Also, if the expression starts with a closure, it needs to have an explicit parameter list, in order to avoid the appearance of a compound statement. This is a hard error.

  These rules are different from Java's "dumb expression" restriction. Unlike Java, Groovy blocks can end with arbitrary (even dumb) expressions, as a consequence of optional 'return' and 'continue' tokens.

  To make the programmer's intention clear, a leading closure must have an explicit parameter list, and must not follow a previous statement separated only by newlines.

### classBlock

    public final void classBlock()

### classDefinition

    public final void classDefinition(antlr.collections.AST modifiers)

### classField

    public final void classField()

### classOrInterfaceType

    public final void classOrInterfaceType(boolean addImagNode)

### classTypeSpec

    public final void classTypeSpec(boolean addImagNode)

### cloneToken

    public Token cloneToken(Token t)

### closableBlock

    public final void closableBlock()

  A sub-block of a block can be either open or closable. It is closable if and only if there are explicit closure arguments. Compare this to a block which is appended to a method call, which is given closure arguments, even if they are not explicit in the code.

### closableBlockConstructorExpression

    public final void closableBlockConstructorExpression()

  A list constructor is a argument list enclosed in square brackets, without labels. Any argument can be decorated with a spread operator (*x), but not a label (a:x). Examples: [], [1], [1,2], [1,*l1,2], [*l1,*l2]. (The l1, l2 must be a sequence or null.)

  A map constructor is an argument list enclosed in square brackets, with labels everywhere, except on spread arguments, which stand for whole maps spliced in. A colon alone between the brackets also forces the expression to be an empty map constructor. Examples: [:], [a:1], [a:1,b:2], [a:1,*:m1,b:2], [*:m1,*:m2] (The m1, m2 must be a map or null.) Values associated with identical keys overwrite from left to right: [a:1,a:2] === [a:2]

  Some malformed constructor expressions are not detected in the parser, but in a post-pass. Bad examples: [1,b:2], [a:1,2], [:1]. (Note that method call arguments, by contrast, can be a mix of keyworded and non-keyworded arguments.)

### closableBlockParam

    public final void closableBlockParam()

### closableBlockParamsOpt

    public final void closableBlockParamsOpt(boolean addImplicit)

  Closure parameters are exactly like method parameters, except that they are not enclosed in parentheses, but rather are prepended to the front of a block, just after the brace. They are separated from the closure body by a CLOSABLE_BLOCK_OP token '->'.

### closableBlockParamsStart

    public final void closableBlockParamsStart()

### closureList

    public final void closureList()

### commandArgument

    public final void commandArgument()

### compatibleBodyStatement

    public final void compatibleBodyStatement()

### compilationUnit

    public final void compilationUnit()

### compoundStatement

    public final void compoundStatement()

  I've split out constructors separately; we could maybe integrate back into variableDefinitions later on if we maybe simplified 'def' to be a type declaration?

### conditionalExpression

    public final void conditionalExpression(int lc_stmt)

### constant

    public final void constant()

### constantNumber

    public final void constantNumber()

  Numeric constant.

### controlExpressionList

    public final void controlExpressionList()

### create

    public antlr.collections.AST create(int type, java.lang.String txt, antlr.collections.AST first)

  Create an AST node with the token type and text passed in, but with the same background information as another supplied Token (e.g. line numbers). To be used in place of antlr tree construction syntax, i.e. #[TOKEN,"text"] becomes create(TOKEN,"text",anotherToken) todo - change antlr.ASTFactory to do this instead...

### create

    public antlr.collections.AST create(int type, java.lang.String txt, Token first, Token last)

### create

    public antlr.collections.AST create(int type, java.lang.String txt, antlr.collections.AST first, Token last)

### declarationStart

    public final void declarationStart()

### declaratorBrackets

    public final void declaratorBrackets(antlr.collections.AST typ)

  After some type names, where zero or more empty bracket pairs are allowed. We use ARRAY_DECLARATOR to represent this. TODO: Is there some more Groovy way to view this in terms of the indexed property syntax?

### matchGenericTypeBracketsFailed

### methodCallArgs

    public final void methodCallArgs(antlr.collections.AST callee)

  An expression may be followed by one or both of (...) and {...}. Note: If either is (...) or {...} present, it is a method call. The {...} is appended to the argument list, and matches a formal of type Closure. If there is no method member, a property (or field) is used instead, and must itself be callable.

  If the methodCallArgs are absent, it is a property reference. If there is no property, it is treated as a field reference, but never a method reference.

  Arguments in the (...) can be labeled, and the appended block can be labeled also. If there is a mix of unlabeled and labeled arguments, all the labeled arguments must follow the unlabeled arguments, except that the closure (labeled or not) is always a separate final argument. Labeled arguments are collected up and passed as a single argument to a formal of type Map.

  Therefore, f(x,y, a:p, b:q) {s} is equivalent in all ways to f(x,y, [a:p,b:q], {s}). Spread arguments of sequence type count as unlabeled arguments, while spread arguments of map type count as labeled arguments. (This distinction must sometimes be checked dynamically.) A plain unlabeled argument is allowed to match a trailing Map or Closure argument: f(x, a:p) {s} === f(*[ x, [a:p], {s} ])
