[CEDET-devel] New check-ins

[David P. <dav...@wa...>]

Hi Eric,

I finally checked-in my experimental wisent C code, plus some minor
enhancements to the grammar framework.  Here is the change log:

2003-07-07  David Ponce  <da...@dp...>

	* semantic/doc/C99-gram.texi
	* semantic/wisent/wisent-c.el:
	* semantic/wisent/wisent-c.wy

	New file.

	* semantic/semantic-ast.el

	New library.
	
	* semantic/semantic-grammar.el

	(semantic-grammar-builtin-names)
	(semantic-grammar-builtin-names-regexp): New variables.
	(semantic-grammar-builtin-names-matcher): New function.
	(semantic-grammar-mode-keywords-1): Use it.

	* semantic/wisent/wisent-grammar.el

	(wisent-grammar-AST-ADD, wisent-grammar-AST-PUT)
	(wisent-grammar-AST-GET, wisent-grammar-AST-GET1)
	(wisent-grammar-AST-GET-STRING)
	(wisent-grammar-AST-MERGE): New functions.
	(wisent-grammar-builtins): Add above new AST built-ins.
	(wisent-grammar-builtin-names): New function.
	(wisent-grammar-expand-builtins): Expand car of expression too.
	(semantic-grammar-mode): Set built-in names.

The wisent-c.wy grammar now uses AST built-in functions in place of
previous wisent-ast function calls.  wisent-ast is now a more general
semantic-ast library.

I improved the way built-in function names are highlighted in grammar
files.  Mainly to facilitate addition of new built-ins.

I introduced a new variable `semantic-grammar-builtin-names' whose
value is the list of built-in function names to highlight.

The new font-lock "matcher": `semantic-grammar-builtin-names-matcher'
uses that variable to search for the built-in names to highlight.

Another advantage is that `semantic-grammar-builtin-names' can be set
based on grammar mode.  So it is possible now to have a different set
of built-ins in `bovine-grammar-mode' and `wisent-grammar-mode'.  For
example, only the latter implements (and highlights) the new AST
built-ins.

Finally, I followed your recommendation and wrote a C99-gram.texi
file that documents the ISO C99 context free grammar wisent-c.wy is
based on.  I put that file in the doc subdirectory.

Enjoy!
David
