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.
class Test {
public static void main( String args[] ) {
if (boolean.class.equals(boolean.class)) {
ETSystem.out.println("works");
