Update of /project/climacs/cvsroot/climacs In directory common-lisp.net:/tmp/cvs-serv12579 Modified Files: climacs.asd gui.lisp packages.lisp syntax.lisp Added Files: lisp-syntax.lisp Log Message: Alternative syntax for editing common lisp (called "Lisp"). I have not completely lost hope of making the Earley-based syntax module fast enough, but as of now I don't know how. This syntax module provides an incremental resynchronizing LR parser for Common Lisp. It is fast enough the parse tree for the entire buffer is kept updated, as opposed to just for what is visible in the CLIM pane. Ultimately, I hope to factor out the parts that are not specific to Lisp into a different module, perhaps the existing syntax.lisp file. I'll be interested in your opinions.
