From d1a7fc5ad7d5bdb26c91b36742d33d83468875d3 Mon Sep 17 00:00:00 2001 From: drewc Date: Sun, 20 Sep 2009 12:39:47 -0700 Subject: [PATCH] New implementation (load "new-description.lisp") of LoL protocol based on Plists. No caching yet, so performance is likely not 100% what it could be, but it's simpler and easier to understand this way. darcs-hash:20090920193947-39164-dcd5c770fbb36b5849656523d8d102dbc4f8e6b1.gz --- src/display-test.lisp | 2 +- src/new-description.lisp | 215 +++++++++++++++++++++++ src/standard-descriptions/edit-test.lisp | 4 +- src/ucw/ucw-test.lisp | 108 ++++++------ 4 files changed, 272 insertions(+), 57 deletions(-) create mode 100644 src/new-description.lisp diff --git a/src/display-test.lisp b/src/display-test.lisp index 6b3f9c8..d076014 100644 --- a/src/display-test.lisp +++ b/src/display-test.lisp @@ -9,7 +9,7 @@ (define-display ((description test-display)) t "BRILLANT!") - (is (equalp "BRILLANT!"
