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 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 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) 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 Based on an original grammar released in the PUBLIC DOMAIN

                              antlr.TokenStreamException

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.

Throws:

antlr.RecognitionException

antlr.TokenStreamException

modifiers

public final void modifiers()
                     throws antlr.RecognitionException,
                            antlr.TokenStreamException

                                      antlr.TokenStreamException

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.

declarationStart

public final void declarationStart()

                                   antlr.TokenStreamException

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'.)

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).

                                                     antlr.TokenStreamException

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.

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).

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 '='.

                                 antlr.TokenStreamException

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} ])

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].

                                                 antlr.TokenStreamException

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.)
