Dear mailing list member,

The past week, I have concentrated my effort on the HTML syntax module, not because HTML is particularly interesting to the Climacs project, but because it is the syntax module that I currently use to determine what parsing-related functionality can be generalized, abstracted out, and used to implement other syntax modules. We are particularly interested in seeing how these generalizations can be used to implement the Common Lisp syntax module.

Aleksandar Bakic continues to work on persistent buffer implementations. He has now started working on a line-oriented persistent buffer implementation that we hope will improve overall performance of Climacs buffer operations.

Christophe Rhodes has been very helpful by pointing out potential problems with buffer delegation and with problems in the interaction between Climacs display functions and McCLIM cut-and-paste functionality.

Here is an itemized list of what happened the past week:

* Made html-syntax display from the sequence of lexemes as opposed to from the buffer itself

* Split off html-syntax into a separate package.

* Fixes of typos and minor problems in the documentation, and updates to the documentation related to delegating-buffer. (thanks to Aleksandar Bakic)

* Performance improvements to the persistent buffer implementation (thanks to Aleksandar Bakic)

* Introduced functions to traverse a parse stack encoded in the sequence of parser states that the Earley parser generates.

* Modified the html-syntax to display from the parse states as long as a valid parse of the buffer exists, and from the sequence of lexemes when no valid parse exists.
