revision 1.8
date: 1996/02/07 15:32:31; author: connolly; state: Exp; lines: +25 -14
* SGML_lexCase -> SGML_lexNorm, which covers whitespace etc.
as well as case conversion. This allows pass-thru filtering.
This involved changing the way whitespace is handled in the lexer.
Also, tag close tokens (>) are explicitly reported.
sgml_lex -c becomes sgml_lex -n
@@ problem remaining: erroneous markup is reported out
of order
* added filter test
* changed excerpt.pl to work with flex 2.5.2
* everything is compiled with -ansi -pedantic-errors -Werror
* @@ grumble... navipress is putting in
* Fixed a bug in main.c reported in:

revision 1.6
date: 1995/11/16 00:59:17; author: connolly; state: Exp; lines: +66 -9
* Added some error recovery and warnings regarding
attribute value literal syntax.
* Added line-number tracking
* SGML_Lexer is passed to the callbacks (so the callback can
get the current line number)
* More markup is passed explicitly to the lexer client
to support "Stream editors" and such.
* Comments aren't separated out from markup declarations
any more -- they're passed in the same event.
* a little more documentation (README, etc.)
* added python stuff to the distribution
* added comments in the tests to resync the lexer between tests
----------------------------
revision 1.5

* Added ATTR vs. ATTRVAL distinction for smarter attribute scanning.

name can be null

* changed * to + in {number}
* fixed termination bug in character reference handling
==sgml_lex.c

revision 1.2
date: 1995/10/07 05:31:20; author: connolly; state: Exp; lines: +179 -44
OK... easy parts work: I have C code that interprets the
scanner data and implements an SGML lexer. But it can
only be called once! I need to work on the buffering stuff.
