A deficu whose function the loaded ICU lacks still declaims its ftype,
so it leaves a trace; what it leaves out is the entry load-icu would
look up again.
Follow cl-icu 259ee67: no global nickname, BIDI-DIRECTION, load errors
The examples are written in a package that gives cl-icu the local
nickname icu, and cl-harfbuzz hb, which Home, Getting started and
Installation show, since the packages have no global nicknames now.
Loading uses asdf:load-system. The type bidi-direction joins the API
index and the page on bidirectional text. The errors of an ICU that
cannot be loaded or lacks a function are icu-errors, with their new
messages and hints, and a constant argument of the wrong type is a
compiler warning. Development describes the new file layout, the form
of %checked and the new tests.
Home and Installation name SBCL as the Lisp. ICU versions and saved
images, whose section "Saved images and implementations" becomes "Saved
images", and Development no longer set SBCL against CCL, and
Development's test command and CI description no longer name CCL.
Follows cl-icu 06d1f63: cl-ffi loads libicuuc again when a saved image
starts and runs load-icu as one of its image-start hooks, so cl-icu/sys
is gone; the examples use cl-ffi's operators, loading libicui18n from a
file name as cl-ffi's load-foreign-library takes one, and a Homebrew ICU
is found through DYLD_FALLBACK_LIBRARY_PATH.
