Fixes a critical issue with macOS [NEWS](https://bitbucket.org/mituharu/emacs-mac/raw/master/NEWS-mac) * emacs-26.1-mac-7.2 (2018-09-09) ** Fixed bugs *** Buffer contents are not displayed on macOS 10.14. This is mainly because now NSViews are backed by Core Animation Layer (layer-backed) by default and non-deferred drawing into views no longer works. Instead of switching to deferred drawing (i.e., draw only inside -[NSView drawRect:]), we draw into our own backing bitmap in a non-deferred way as before, and update the view contents with the resulting image via -[NSView updateLayer]. This "application-side double buffering" is also available on OS X 10.8 - macOS 10.13 if you set the frame parameter `inhibit-double-buffering' to nil when creating a frame. Just like on macOS 10.14, such a frame does not do LCD smoothing. *** Screenshot grabbed via Services is displayed in wrong size when we have display mirroring between Retina and non-Retina displays. *** Cursor movement just after frame resize sometimes leaves garbage. *** Crash by the Fall_threads call from the GUI thread at the select emulation when there are multiple Lisp threads. *** Info title has ASCII underline unlike other window systems. *** Vertical scroll bar is created as horizontal if frame font height is short. ** Improvements *** macOS 10.14 adds property :appearance to (mac-application-state). The value may be "NSAppearanceNameAqua" or "NSAppearanceNameDarkAqua". *** Add new color format "mac:COLOR-LIST-NAME:COLOR-NAME" and "mac:COLOR-NAME" (shorthand for "mac:System:COLOR-NAME"). The actual color may be different depending on the global appearance setting on macOS 10.14. For example, "mac:textColor" is black on the Light Mode but is white on the Dark Mode. *** Default frame colors respect appearance setting on macOS 10.14. Now the default frame foreground/background color is "mac:textColor"/"mac:textBackgroundColor", respectively. Changes of the system setting of the global appearance are dynamically reflected. *** New function `mac-color-list-alist' to get the available combinations of COLOR-LIST-NAMEs and COLOR-NAMEs. Note that this value is dependent on user environment and OS version. Also, some combinations may represent image patterns rather than colors. For the former cases, `(color-values "mac:COLOR-LIST-NAME:COLOR-NAME")' returns nil. |
