Re: Emacs 23 Mac port

[YAMAMOTO Mitsuharu]

The twelfth update of the Mac port, which is experimental/hackers-only,
is now available from

    ftp://ftp.math.s.chiba-u.ac.jp/emacs/emacs-23.1.97-mac-1.992.tar.gz

This version is based on Emacs 23.1.97 pretest.

** Fixed bugs

*** Tooltips don't respect customized `tooltip' face font setting.

*** Font specs specified for non-ASCII characters in a non-default
fontset are not used in new frames.  Reported by Ichiro Enoki.

** Improvements

*** New function `mac-file-alias-p', which is parallel to
`file-symlink-p'.


Being a port of upcoming Emacs 23.2, the Mac port supports the
following features:

  * The `fullscreen' frame parameter, with all values supported:
    `fullboth', `fullwidth', `fullheight', and 'maximized'.  The
    fullboth frames, which don't have the title bar, still allow us to
    access the menu bar, the Dock (Mac OS X 10.3 and later), and the
    tool bars.  The menu bar can also be activated via
    `menu-bar-open', `Control-F2' (if full keyboard access enabled),
    or `Command-Shift-/' (on Mac OS X 10.5 and later) even for
    fullboth frames where the menu bar is usually hidden.  Changing
    fonts or internal-border-width in fullscreen frames does not
    clutter display.  On multiple monitor environments, one can move
    fullscreen frames to another monitor by setting the `left' and
    `top' frame parameters accordingly.  Attaching/detaching external
    monitors should work even with fullscreen frames.

  * The `sticky' frame parameter, which allows us to keep particular
    frames visible for all Spaces on Mac OS X 10.5 and later.

  * The function `system-move-file-to-trash', which can be specified
    as a value of `delete-by-moving-to-trash'.

  * SVG image display.  This can be done via the WebKit framework on
    Mac OS X 10.4 and later, so you don't need librsvg.

  * Multi-page TIFF images.

  * The function `x-select-font' that provides modal font selection
    dialog in a compatible way with GTK+ and W32 ones.  Note that a
    nonmodal counterpart has been available since Emacs 22 Carbon port
    via `mac-font-panel-mode'.

  * Unicode character display including non-BMP ones.

  * Complex text layout (left-to-right only) and text shaping.  They
    are implemented using the Core Text or NS Text layout engine, so
    you don't need libotf.

  * Glyph selection with variation selectors.  Most of Adobe-Japan1
    ideographic glyphs are accessible via IVSes (Ideographic Variation
    Sequences) even for the OS-bundled Hiragino fonts, which do not
    contain the UVS subtable in their cmap table as of Mac OS X 10.6.
