SRI international 发布的OAA框架软件

1.00B1 Fixes:
Missing includes from antlr.h

1.00B2 Fixes:
Didn't save _t during (...)?

1.00B3 Fixes:
Fixed bug that wouldn't allow labels on wildcard nodes
Would dump argument list to some labelled rule refs
Fixed code gen bug with #(. B) as last element of production

1.00B4 Fixes:
Another teeny-weeny little code gen fix related to "rule > [result]"

1.00B5 Fixes:
Made tar file create a root directory called sorcerer
Line 465 in gen.c had an 'stdout' where an 'output' was needed.

1.00B6 Fixes:
K&R function headers were missing a ',' in the argument list
Made the default prototype style the same as how you compiled SORCERER itself.

1.00B7
Rik Faith <[e-mail]>:
	[...] patch fixes a bug in sorcerer where the "actions" in the
	input file which appeared between the second set of << >>'s (i.e.,
	the user's main routine) would format poorly in the output file.

1.00B8:
changed the STreeTry() macro (it's much better now)
added -transform option (double pointers now needed in tree structure)
added ``!'' operator to indicate what is not to be included in tree copy
	from input to output tree in transform mode.
Added _result parameter for transform mode
Changed sorcerer.c to errsupport.c; sorcerer.c is now regular support code.
function sorcerer_panic() was added
Added all of the libraries for tree rewrite support
	(ast.c slist.c sint.c hash.c sstack.c)
	Added a very cool function ast_scan(); check it out
Added @-variables; e.g., @(int i = 3) ... @i = 4;
Added __USE_PROTOS definition in sorcerer.h
SORCERER now reads the config.h file used by ANTLR/DLG.
Uses ast_right(rw) and ast_down(rw) so C/C++ compatible -- also means
	C/C++ can have different tree layout and use these as functions to
	simulate child-sibling trees.
Fixed: Bad error messages:
	a : A | (b)? b;
	b : B;
	error: infinite recursion from rule a to rule b
Fixed a bug:
    Sorcerer  a simple tree-parser generator  Version 1.00B3  1992-1994

           )*
           )
           ;

1.00B9:
Fixed support/ast.c so K&R C would compile it.

1.00B13:
Totally new, cool, simple tree rewriting mechanism.  Not many bug fixes

Made enum def ignore #ifdef #else #endif etc... in #tokdefs

Added C++ support

Made h and lib directory

Changed name: AST_NONTRANSFORM_FIELDS -> AST_REQD_FIELDS

-def-tokens and -proto-file are not valid in C++ mode.

Changed name: AST -> SORAST in C and C++.

When you -def-tokens, it generates them ast consts inside class def.
	Ref with classname::def.

All #[] constructor calls must be done in class A { ... } def of grammar
	so it knows which to call.  Else, put Classname:: on front manually.

1.00B14

[Not completed yet]

#label -> label; #label is no longer valid.  Just use label to access
output node in transform mode.  label_in is the input node (for token
references only).

ast_node, ast_dup -> shallowCopy() (user must define for transform
mode), deepCopy().

Fixed the C support functions for ASTs

#[] -> new SORAST

token() -> type()  (sorry, but had to make more consistent)
setToken() -> setType() (you can just add type() { token(); } if you want).

Remove guessing gate on actions if no (...)?

Wildcard as root of tree made SOR bomb

All the token field refs in PCCTSAST.C -> type()

ASTBase::double_link didn't check for NULL pointers.

#if in action caused trouble.

made action buffer bigger (8k bytes)

SORCERER had a bug in that it did not update the tree result before
returning sometimes.

PCCTS_AST::ast_scan() is now non-virtual

C++ support functions like tail(), bottom(), etc... now use 'this'
pointer rather a passed argument.

Sorcerer spun when it found identifier+ instead of (identifier)+ in a
tree rule.

This version corresponds pretty to the state of the book.

1.00B15

All .C files are changed to .cpp.

ASTBase::dup() and ASTDoublyLinkedBase::dup() now call shallowCopy()
to actually duplicate a node.  shallowCopy() can either call a copy
constructor or can just duplicate things right there.

C++ keyword "template" was used as a variable in some SORCERER files.

1.00b20  (2-Oct-1998)

Minor changes as reported in CHANGES_FROM_1.33 of the main pccts
distribution kit.  Main reason for change in version number is to
indicate that it matches the new release of pccts 1.33MR15.
