-
- Garnet is a comprehensive user interface development environment for
- Lisp. It has run on Unix and X/11 for about 6 years, and this release
- announces the availability on the Macintosh using the native Macintosh
- QuickDraw and operating system. The intention is to provide a free,
- portable toolkit for user interface development in Lisp. In
- particular, we expect that all current Garnet Unix applications should
- run on the Macintosh without change, and applications written on the
- Macintosh version should work on the Unix version. Note, however,
- that we have NOT created or interfaced to the Macintosh widgets so on
- the Macintosh you will still have to use Garnet or Motif look-and-feel
- widgets. We hope that some users will address this.
-
- For those unfamiliar with Garnet, it contains two complete widgets
- sets implemented in Lisp, and a full set of interactive tools
- including an interface builder. More details about Garnet are
- available in the Garnet FAQ:
- ftp://a.gp.cs.cmu.edu/usr/garnet/garnet/FAQ
- which is posted periodically.
-
- The primary change for version 3.0 is that Garnet now works on the
- Macintosh. Current Unix users of Garnet will not see much difference
- between version 2.2 and 3.0, but you will need to get the new version and
- recompile if you want to port your software to the Macintosh.
-
- To run the Macintosh version of Garnet, you need to have System 7.0 or
- later, Macintosh Common Lisp (MCL) version 2.0.1 or later, and at
- least 8Mb of RAM. The system takes about 10 megabytes of disk space
- on a Mac, not including the documentation (which takes an additional 8
- megabytes). We find that performance of Garnet on MCL is acceptable
- on Quadra's, and fine on a Quadra 840 A/V. It is really too slow on a
- Mac II. To do anything useful, you probably need 12mb of memory. A
- PowerPC Mac does not work well for Lisp (see discussion on
- comp.lang.lisp.mcl). With your help, we hope to improve the
- performance so it runs on smaller machines.
-
- For the current Unix users of Garnet 2.2, there are a few minor
- changes to the system for version 3.0, some of which are
- NOT BACKWARDS COMPATIBLE!
-
- * All Garnet files have been updated to adhere to the new lisp standards
- defined in Common Lisp the Language Second Edition. This involved changes
- to package definitions, export statements, and removal of Garnet's binding
- of excl::*cltl1-in-package-compatibility-p* and comp:*cltl1-compile-file-
- toplevel-compatibility-p* in Allegro lisp. If your lisp files used to
- rely on Garnet to set up a CLTL1-compatible environment, you may have
- to either bring your files up-to-date to the new standard or declare the
- old initializations yourself.
-
- * We removed support for "#\" specification of modified characters, and
- now support only keyword forms of modified characters. For example,
- all occurrences of #\control-c should be converted to :CONTROL-c, as
- specified in the Garnet 2.2 Interactors manual. The reason for this
- change is that the CHAR-BITS function which in some lisps (like
- Allegro) would report special properties of characters (like whether
- they are modified by a control key) has been explicitly removed from
- the CLTL2 specification.
-
- * The :face slot of font objects can now take a list of keywords.
- In previous versions of Garnet, the only allowed values for the :face
- slot were :roman, :bold, :italic, and :bold-italic. In Garnet 3.0, you
- can also supply the value '(:bold :italic) (independent of order). For
- the Mac version, you can supply any single element or any consistent
- combination of :roman, :bold, :italic, :bold-italic, :plain, :condense,
- :extend, :outline, :shadow, or :underline.
-
- * Now :omit-title-bar-p parameters are in both kinds of scrolling-windows.
-
- * The interface to declaring constant information about fonts and
- colors is incomplete in this release of Garnet 3.0 Alpha. Thus, many
- formulas that would have previously been eliminated in your system may
- not be eliminated by this version of Garnet, since display-dependent
- information is now stored in a new control schema named
- opal::DEVICE-INFO. At minimum, to eliminate font and color formulas,
- you will have to commit to not changing display of the lisp session in
- which the font and color information was obtained by declaring the
- :current-device slot of opal::DEVICE-INFO constant. In particular,
- you would not be able to make an executable lisp image of Garnet after
- declaring the display information constant, since restarting the
- Garnet image requires reinitializing the display to a new value.
-
- * Since the Mac limits the number of characters in file names, we had
- to change the names of seven gadget files, where the names of the
- duplicates have been truncated to 31 characters:
- motif-prop-sheet-win-loader.lis
- motif-scrolling-labeled-box-loa
- motif-scrolling-labeled-box.lis
- motif-scrolling-menu-loader.lis
- motif-scrolling-window-loader.l
- scrolling-input-string-loader.l
- scrolling-labeled-box-loader.li
- If you plan to run your application on the Mac, you should use the function
- user::garnet-load (described in the Garnet 2.2 Overview manual) whenever
- you are loading gadgets, instead of using LOAD directly. GARNET-LOAD will
- automatically map the standard Garnet file name that you supply into the
- list of truncated filenames for the Mac. GARNET-LOAD also does the
- correct thing under Unix.
-
- * The internal representation of opal:white-fill has been changed.
- Previously, opal:white-fill was considered one of the "gray stippled"
- bitmaps, and had a foreground-color of black, but was drawn entirely
- in its background-color of white. This confused some applications like
- color palettes that relied on the :foreground-color slot of filling-style
- objects for their color. To accommodate users' intuition, opal:white-fill
- is now considered to be a "solid color" filling-style, with a
- :foreground-color of white. Opal:white-fill is no longer associated with
- the halftone filling-styles.
-
- * Top-level loader files, including garnet-loader.lisp, are now loaded into
- the :COMMON-LISP-USER package. The CLTL2 standard and most lisps have one
- package named :COMMON-LISP-USER with a nickname of :USER, and one package
- named :COMMON-LISP with a nickname of :LISP. We have added Lucid-specific
- code at the top of garnet-loader.lisp and garnet-compiler.lisp that adjust
- the nicknames of Lucid's :USER and :LISP packages to accommodate the new
- CLTL2-compatible files.
-
- * The multi-selection now supports selections across multiple windows.
- As described in the comments at the top of the file, you should have a
- multi-graphics-selection gadget in each window, and each should have
- the :other-multi-graphics-selection slot set with a list of ALL the
- multi-graphics-selection gadgets. Then, each gadget's :value will
- reflect selections in all windows. This change should not affect
- current users (it is backwards compatible). A known bug is that the
- selection order is NOT preserved across multiple windows (you can't
- tell which object was selected first or last). Also, you cannot drag
- objects from one window to another.
