JSR-241 Groovy Recognizer Run 'java Main [-showtree] directory-full-of-groovy-files' [The -showtree option pops up a Swing frame that shows the AST constructed from the parser.] Contributing authors: John Mitchell johnm@non.net Terence Parr parrt@magelang.com John Lilley jlilley@empathy.com Scott Stanchfield thetick@magelang.com Markus Mohnen mohnen@informatik.rwth-aachen.de Peter Williams pete.williams@sun.com Allan Jacobs Allan.Jacobs@eng.sun.com Steve Messick messick@redhills.com James Strachan jstrachan@protique.com John Pybus john@pybus.org John Rose rose00@mac.com Jeremy Rayner groovy@ross-rayner.com Alex Popescu the.mindstorm@gmail.com Martin Kempf mkempf@hsr.ch Reto Kleeb rkleeb@hsr.ch Version 1.00 December 9, 1997 -- initial release Version 1.01 December 10, 1997 fixed bug in octal def (0..7 not 0..8) Version 1.10 August 1998 (parrt) added tree construction fixed definition of WS,comments for mac,pc,unix newlines added unary plus Version 1.11 (Nov 20, 1998) Added "shutup" option to turn off last ambig warning. 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 charVocabulay 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 thats 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 MyParameterised() o Added typeArguments to postfixExpression productions for anonymous inner class super constructor invocation, e.g. new Outer().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(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()

### balancedBrackets

    public final void balancedBrackets()

  Fast lookahead across balanced brackets of all sorts.

### balancedTokens

    public final void balancedTokens()

### blockBody

    public final void blockBody(int prevToken)

  A block body is a parade of zero or more statements or expressions.

### 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

### 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.

### cloneToken

    public Token cloneToken(Token t)

  Clones the token

### closableBlock

    public final void closableBlock()

  A block which is known to be a closure, even if it has no apparent arguments. A block inside an expression or after a method call is always assumed to be a closure. Only labeled, unparameterized blocks which occur directly as substatements are kept open.

### closableBlockConstructorExpression

    public final void closableBlockConstructorExpression()

### closableBlockParam

    public final void closableBlockParam()

  Simple names, as in {x|...}, are completely equivalent to {(def x)|...}. Build the right AST.

### 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()

  Lookahead to check whether a block begins with explicit closure arguments.

### closureList

    public final void closureList()

### commandArgument

    public final void commandArgument()

### commandArguments

    public final void commandArguments(AST head)

  A member name (x.y) or element name (x[y]) can serve as a command name, which may be followed by a list of arguments. Unlike parenthesized arguments, these must be plain expressions, without labels or spread operators.

### compatibleBodyStatement

    public final void compatibleBodyStatement()

  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.

### compilationUnit

    public final void compilationUnit()

### compoundStatement

    public final void compoundStatement()

### conditionalExpression

    public final void conditionalExpression(int lc_stmt)

### constant

    public final void constant()

  Numeric, string, regexp, boolean, or null constant.

### constantNumber

    public final void constantNumber()

  Numeric constant.

### constructorBody

    public final void constructorBody()

### constructorDefinition

    public final void constructorDefinition(AST mods)

  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?

### constructorStart

    public final void constructorStart()

  Used to look ahead for a constructor

### controlExpressionList

    public final void controlExpressionList()

### create

    public AST create(int type, String txt, 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

### create

    public AST create(int type, String txt, AST first, Token last)

### create

    public AST create(int type, String txt, AST first, AST last)

### declaration

    public final void declaration()

  A declaration is the creation of a reference or primitive-type variable, or (if arguments are present) of a method. Generically, this is called a 'variable' definition, even in the case of a class field or method. It may start with the modifiers and/or a declaration keyword "def". It may also start with the modifiers and a capitalized type name.

  AST effect: Create a separate Type/Var tree for each var in the var list. Must be guarded, as in (declarationStart) => declaration.

### declarationStart

    public final void declarationStart()

  Used only as a lookahead predicate, before diving in and parsing a declaration. A declaration can be unambiguously introduced with "def", an annotation or a modifier token like "final". It may also be introduced by a simple identifier whose first character is an uppercase letter, as in {String x}. A declaration can also be introduced with a built in type like 'int' or 'void'. Brackets (array and generic) are allowed, as in {List[] x} or {int[][] y}. Anything else is parsed as a statement of some sort (expression or command).

  (In the absence of explicit method-call parens, we assume a capitalized name is a type name. Yes, this is a little hacky. Alternatives are to complicate the declaration or command syntaxes, or to have the parser query the symbol table. Parse-time queries are evil. And we want both {String x} and {println x}. So we need a syntactic razor-edge to slip between 'println' and 'String'.) *TODO* The declarationStart production needs to be strengthened to recognize things like {List foo}. Right now it only knows how to skip square brackets after the type, not angle brackets. This probably turns out to be tricky because of >> vs. > >. If so, just put a TODO comment in.

### declaratorBrackets

    public final void declaratorBrackets(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?

### dynamicMemberName

    public final void dynamicMemberName()

  If a dot is followed by a parenthesized or quoted expression, the member is computed dynamically, and the member selection is done only at runtime. This forces a statically unchecked member access.

### enumBlock

### exclusiveOrExpression

    public final void exclusiveOrExpression(int lc_stmt)

### explicitConstructorInvocation

    public final void explicitConstructorInvocation()

  Catch obvious constructor calls, but not the expr.super(...) calls

### expression

    public final void expression(int lc_stmt)

### expressionStatement

    public final void expressionStatement(int prevToken)

  An expression statement can be any general expression.

  An expression statement can also be a command, which is a simple method call in which the outermost parentheses are omitted.

  Certain "suspicious" looking forms are flagged for the user to disambiguate.

### finallyClause

    public final void finallyClause()

### forCond

    public final void forCond()

### forIter

    public final void forIter()

### forStatement

### genericMethod

    public final void genericMethod()

### genericMethodStart

    public final void genericMethodStart()

  lookahead predicate for usage of generics in methods as parameter for the method. Example: static T foo(){} 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.

### getLexer

    public GroovyLexer getLexer()

### getWarningList

    public List getWarningList()

### handler

    public final void handler()

### identifier

    public final void identifier()

### identifierStar

    public final void identifierStar()

### implementsClause

    public final void implementsClause()

### implicitParameters

    public final void implicitParameters()

  A block known to be a closure, but which omits its arguments, is given this placeholder. A subsequent pass is responsible for deciding if there is an implicit 'it' parameter, or if the parameter list should be empty.

### importStatement

    public final void importStatement()

### inclusiveOrExpression

    public final void inclusiveOrExpression(int lc_stmt)

### indexPropertyArgs

    public final void indexPropertyArgs(AST indexee)

  An expression may be followed by [...]. Unlike Java, these brackets may contain a general argument list, which is passed to the array element operator, which can make of it what it wants. The brackets may also be empty, as in T[]. This is how Groovy names array types.

  Returned AST is [INDEX_OP, indexee, ELIST].

### interfaceBlock

    public final void interfaceBlock()

### interfaceDefinition

    public final void interfaceDefinition(AST modifiers)

### interfaceExtends

    public final void interfaceExtends()

### interfaceField

    public final void interfaceField()

### keywordPropertyNames

    public final void keywordPropertyNames()

  Allowed keywords after dot (as a member name) and before colon (as a label). TODO: What's the rationale for these?

### listOfVariables

    public final void listOfVariables(AST mods, AST t, Token first)

### listOrMapConstructorExpression

    public final void listOrMapConstructorExpression()

  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.)

### logicalAndExpression

### matchGenericTypeBracketsFailed

    public void matchGenericTypeBracketsFailed(String problem, String solution)

### methodCallArgs

    public final void methodCallArgs(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} ])

### modifier

    public final void modifier()

### modifiers

    public final void modifiers()

  A list of one or more modifier, annotation, or "def".

  This is the grammar for what can follow a dot: x.a, x.@a, x.&a, x.'a', etc. Note: `typeArguments` is handled by the caller of `namePart`.

### newArrayDeclarator

    public final void newArrayDeclarator()

### newExpression

    public final void newExpression()

  object instantiation. Trees are built as illustrated by the following input/tree pairs: new T() new | T -- ELIST | arg1 -- arg2 -- .. -- argn new int[] new | int -- ARRAY_DECLARATOR new int[] {1,2} new | int -- ARRAY_DECLARATOR -- ARRAY_INIT | EXPR -- EXPR | | 1 2 new int[3] new | int -- ARRAY_DECLARATOR | EXPR | 3 new int[1][2] new | int -- ARRAY_DECLARATOR | ARRAY_DECLARATOR -- EXPR | | EXPR 1 | 2

### nls

  Zero or more insignificant newlines, all gobbled up and thrown away.

### nlsWarn

    public final void nlsWarn()

  Zero or more insignificant newlines, all gobbled up and thrown away, but a warning message is left for the user, if there was a newline.

### openBlock

    public final void openBlock()

  An open block is not allowed to have closure arguments.

### openOrClosableBlock

    public final void openOrClosableBlock()

  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.

### packageDefinition

    public final void packageDefinition()

### parameterDeclaration

    public final void parameterDeclaration()

  A formal parameter for a method or closure.

### parameterDeclarationList

    public final void parameterDeclarationList()

  A list of zero or more formal parameters. If a parameter is variable length (e.g. String... myArg) it should be to the right of any other parameters of the same kind. General form: (req, ..., opt, ..., [rest], key, ..., [restKeys], [block] This must be sorted out after parsing, since the various declaration forms are impossible to tell apart without backtracking.

### parameterModifiersOpt

    public final void parameterModifiersOpt()

### parenthesizedExpression

    public final void parenthesizedExpression()

### pathElement

    public final void pathElement(AST prefix)

### pathElementStart

    public final void pathElementStart()

### pathExpression

    public final void pathExpression(int lc_stmt)

  A "path expression" is a name or other primary, possibly qualified by various forms of dot, and/or followed by various kinds of brackets. It can be used for value or assigned to, or else further qualified, indexed, or called. It is called a "path" because it looks like a linear path through a data structure. Examples: x.y, x?.y, x*.y, x.@y; x[], x[y], x[y,z]; x(), x(y), x(y,z); x{s}; a.b[n].c(x).d{s} (Compare to a C lvalue, or LeftHandSide in the JLS section 15.26.) General expressions are built up from path expressions, using operators like '+' and '='.

### postfixExpression

### singleDeclarationNoInit

    public final void singleDeclarationNoInit()

  A declaration with one declarator and no initialization, like a parameterDeclaration. Used to parse loops like `for (int x in y)` (up to the `in` keyword).

### singleVariable

    public final void singleVariable(AST mods, AST t)

  Used in cases where a declaration cannot have commas, or ends with the "in" operator instead of '='.

### snippetUnit

    public final void snippetUnit()

  A Groovy script or simple expression. Can be anything legal inside {...}.

### statement

    public final void statement(int prevToken)

### superClassClause

    public final void superClassClause()

### suspiciousExpressionStatementStart

    public final void suspiciousExpressionStatementStart()

  Lookahead for suspicious statement warnings and errors.

### throwsClause

### traceIn

    public void traceIn(String rname)

### traceOut

    public void traceOut(String rname)

### tryBlock

### typeArgumentBounds

    public final void typeArgumentBounds()

### typeArgumentSpec

    public final void typeArgumentSpec()

### typeArguments

    public final void typeArguments()

### typeArgumentsOrParametersEnd

    protected final void typeArgumentsOrParametersEnd()

### typeDeclarationStart

    public final void typeDeclarationStart()

  Used only as a lookahead predicate for nested type declarations.

### typeDefinitionInternal

    protected final void typeDefinitionInternal(AST mods)

### typeNamePairs

    public final void typeNamePairs(AST mods, Token first)

### typeParameter

    public final void typeParameter()

### typeParameterBounds

    public final void typeParameterBounds()

### typeParameters

    public final void typeParameters()

### typeSpec

    public final void typeSpec(boolean addImagNode)

### unaryExpression

    public final void unaryExpression(int lc_stmt)

### unaryExpressionNotPlusMinus

    public final void unaryExpressionNotPlusMinus(int lc_stmt)

### upperCaseIdent

    public final void upperCaseIdent()

  An IDENT token whose spelling is required to start with an uppercase letter. In the case of a simple statement {UpperID name} the identifier is taken to be a type name, not a command name.

### varInitializer

    public final void varInitializer()

  An assignment operator '=' followed by an expression. (Never empty.)

### variableDeclarator

    public final void variableDeclarator(AST mods, AST t, Token first)

  Declaration of a variable. This can be a class/instance variable, or a local variable in a method It can also include possible initialization.

### variableDefinitions

    public final void variableDefinitions(AST mods, AST t)

  The tail of a declaration. Either v1, v2, ... (with possible initializers) or else m(args){body}. The two arguments are the modifier list (if any) and the declaration head (if any). The declaration head is the variable type, or (for a method) the return type. If it is missing, then the variable type is taken from its initializer (if there is one). Otherwise, the variable type defaults to 'any'. DECIDE: Method return types default to the type of the method body, as an expression.

### variableName

    public final void variableName()

### wildcardType

    public final void wildcardType()
