(init_display) [macintosh]: initialization for window system. * emacs.c (main) [macintosh]: Call syms_of_textprop, syms_of_macfns, syms_of_ccl, syms_of_fontset, syms_of_xterm, syms_of_search, x_term_init, and init_keyboard before calling init_window_once. Also, call syms_of_xmenu. * fontset.c (syms_of_fontset) [macintosh]: Set ASCII font of default fontset to Monaco. * frame.c [macintosh]: Include macterm.h. Remove declarations of NewMacWindow and DisposeMacWindow. (make_terminal_frame) [macintosh]: Call make_mac_terminal_frame instead of calling NewMacWindow and setting fields of f->output_data.mac directly. Call init_frame_faces. (Fdelete_frame) [macintosh]: Remove unused code. (Fmodify_frame_parameters) [macintosh]: Call x_set_frame_parameters instead of mac_set_frame_parameters. * frame.h [macintosh]: Define menu_bar_lines field in struct frame. Define FRAME_EXTERNAL_MENU_BAR macro. * keyboard.c [macintosh]: Include macterm.h. (kbd_buffer_get_event) [macintosh]: Generate delete_window_event and menu_bar_activate_event type events as for X and NT. (make_lispy_event) [macintosh]: Construct lisp events of type MENU_BAR_EVENT as for X and NT. * sysdep.c [macintosh]: Remove declaration for sys_signal. Include stdlib.h. Remove definition of Vx_bitmap_file_path. (sys_subshell) [macintosh]: Remove definition entirely. (init_sys_modes) [macintosh]: Do not initialize Vwindow_system and Vwindow_system_version here. Remove initialization of Vx_bitmap_file_path. (read_input_waiting): Correct the number of parameters passed to read_socket_hook. Move all Macintosh functions to mac/mac.c. * term.c [macintosh]: Include macterm.h. * window.c [macintosh]: Include macterm.h. * xdisp.c [macintosh]: Include macterm.h. Declare set_frame_menubar and pending_menu_activation. (echo_area_display) [macintosh]: Do not return if terminal frame is the selected frame. (update_menu_bar) [macintosh]: Check FRAME_EXTERNAL_MENU_BAR (f). Allow only the selected frame to set menu bar. (redisplay_window) [macintosh]: Obtain menu bar to redisplay by calling FRAME_EXTERNAL_MENU_BAR (f). (display_menu_bar) [macintosh]: Check FRAME_MAC_P (f). * xfaces.c [macintosh]: Include macterm.h. Define x_display_info and check_x. Declare XCreateGC. Define x_create_gc and x_free_gc. Initialize font_sort_order. (x_face_list_fonts) [macintosh]: Use the same code as WINDOWSNT, but call x_list_fonts instead of w32_list_fonts. (Finternal_face_x_get_resource) [macintosh]: Do not call display_x_get_resource. (prepare_face_for_display) [macintosh]: Set xgcv.font. (realize_x_face) [macintosh]: Load the font if it is specified in ATTRS. (syms_of_xfaces) [macintosh]: Initialize Vscalable_fonts_allowed to Qt. * cus-edit.el (custom-button-face): Use 3D look for mac. (custom-button-pressed-face): Likewise. * faces.el (set-face-attributes-from-resources): Handle mac frames in the same way as x and w32 frames. (face-valid-attribute-values): Likewise. (read-face-attribute): Likewise. (defined-colors): Likewise. (color-defined-p): Likewise. (color-values): Likewise. (display-grayscale-p): Likewise. (face-set-after-frame-default): Likewise. (mode-line): Same default face as for x and w32. (tool-bar): Likewise. * frame.el: Remove call to frame-notice-user-settings at end of the file. * info.el (Info-fontify-node): make underlines invisible for mac as for x, pc, and w32 frame types. * term/mac-win.el: New file. --- lisp/ChangeLog | 25 + lisp/cus-edit.el | 6 + lisp/faces.el | 18 +- lisp/frame.el | 1 - lisp/info.el | 2 +- lisp/term/mac-win.el | 1075 +++ mac/.emacs | 10 + mac/ChangeLog | 67 + mac/INSTALL | 105 + mac/README | 33 + mac/emacs-cw5.mcp.xml | 2053 ++++++ mac/emacs-cw6.mcp.xml | 2309 +++++++ mac/inc/alloca.h | 8 + mac/inc/cmdline-defs-cw5.h | 2 + mac/inc/cmdline-defs-cw6.h | 4 + mac/inc/config.h | 570 ++ mac/inc/dirent.h | 48 + mac/inc/epaths.h | 61 + mac/inc/m-mac.h | 140 + mac/inc/macgui.h | 155 + mac/inc/macterm.h | 665 ++ mac/inc/pwd.h | 37 + mac/inc/s-mac.h | 320 + mac/inc/sys/file.h | 59 + mac/inc/sys/ioctl.h | 31 + mac/inc/sys/param.h | 28 + mac/inc/sys/stat.h | 86 + mac/inc/sys/time.h | 31 + mac/inc/sys/types.h | 40 + mac/inc/termio.h | 68 + mac/inc/utime.h | 37 + mac/inc/utsname.h | 32 + mac/makefile.MPW | 1127 ++++ mac/src/Emacs.r | 700 ++ mac/src/EmacsMPW.r | 47 + mac/src/chdir.c | 43 + mac/src/mac.c | 2637 ++++++++ mac/src/macfns.c | 9913 ++++++++++++++++++++++++++++ mac/src/macmenu.c | 2206 +++++++ mac/src/macterm.c | 12446 +++++++++++++++++++++++++++++++++++ src/ChangeLog | 70 + src/dispextern.h | 2 +- src/dispnew.c | 14 + src/emacs.c | 37 +- src/fontset.c | 6 + src/frame.c | 39 +- src/frame.h | 4 +- src/keyboard.c | 14 +- src/sysdep.c | 1574 +---- src/term.c | 3 + src/window.c | 3 + src/xdisp.c | 28 +- src/xfaces.c | 60 +- 53 files changed, 37472 insertions(+), 1627 deletions(-) create mode 100644 lisp/term/mac-win.el create mode 100644 mac/.emacs create mode 100644 mac/ChangeLog create mode 100644 mac/INSTALL create mode 100644 mac/README create mode 100644 mac/emacs-cw5.mcp.xml create mode 100644 mac/emacs-cw6.mcp.xml create mode 100644 mac/inc/alloca.h create mode 100644 mac/inc/cmdline-defs-cw5.h create mode 100644 mac/inc/cmdline-defs-cw6.h create mode 100644 mac/inc/config.h create mode 100644 mac/inc/dirent.h create mode 100644 mac/inc/epaths.h create mode 100644 mac/inc/m-mac.h create mode 100644 mac/inc/macgui.h create mode 100644 mac/inc/macterm.h create mode 100644 mac/inc/pwd.h create mode 100644 mac/inc/s-mac.h create mode 100644 mac/inc/sys/file.h create mode 100644 mac/inc/sys/ioctl.h create mode 100644 mac/inc/sys/param.h create mode 100644 mac/inc/sys/stat.h create mode 100644 mac/inc/sys/time.h create mode 100644 mac/inc/sys/types.h create mode 100644 mac/inc/termio.h create mode 100644 mac/inc/utime.h create mode 100644 mac/inc/utsname.h create mode 100644 mac/makefile.MPW create mode 100644 mac/src/Emacs.r create mode 100644 mac/src/EmacsMPW.r create mode 100644 mac/src/chdir.c create mode 100644 mac/src/mac.c create mode 100644 mac/src/macfns.c create mode 100644 mac/src/macmenu.c create mode 100644 mac/src/macterm.c diff --git a/lisp/ChangeLog b/lisp/ChangeLog index 0e2b2b2a62..2531ef0de1 100644 --- a/lisp/ChangeLog +++ b/lisp/ChangeLog @@ -1,3 +1,28 @@ +2000-10-23 Andrew Choi + + * cus-edit.el (custom-button-face): Use 3D look for mac. + (custom-button-pressed-face): Likewise. + + * faces.el (set-face-attributes-from-resources): Handle mac frames + in the same way as x and w32 frames. + (face-valid-attribute-values): Likewise. + (read-face-attribute): Likewise. + (defined-colors): Likewise. + (color-defined-p): Likewise. + (color-values): Likewise. + (display-grayscale-p): Likewise. + (face-set-after-frame-default): Likewise. + (mode-line): Same default face as for x and w32. + (tool-bar): Likewise. + + * frame.el: Remove call to frame-notice-user-settings at end of + the file. + + * info.el (Info-fontify-node): make underlines invisible for mac + as for x, pc, and w32 frame types. + + * term/mac-win.el: New file. + 2000-10-22 Dave Love * textmodes/refill.el: New file. diff --git a/lisp/cus-edit.el b/lisp/cus-edit.el index a88fe81ba5..9dc8ef02a1 100644 --- a/lisp/cus-edit.el +++ b/lisp/cus-edit.el @@ -1711,6 +1711,9 @@ and `face'."

Then choose Project->Make. Note that this does not +build the DOC file. To do so, use MPW and build the target "Doc" in +makefile.MPW. + +Once built, the Emacs application (Emacs CW or Emacs MPW) can be +launched where it is created. + +To build an optimized version of Emacs in CodeWarrior, change the +value in the Emacs Settings->Code Generation->Global Optimization +dialog. To build a version for profiling, check the Profiler +Information box in the Emacs Settings->Code Generation->PPC Processor +dialog and include the Profiler PPC.Lib library. + +To build optimized or debugging version of Emacs in MPW, follow the +comment in makefile.MPW to enable the -opt speed or -sym on option +(see note below). + +The Mac version requires compiled Lisp files to be present in the lisp +directory to run properly. It is cumbersome to bootstrap from only +the Lisp source files. One way of getting the compiled Lisp files is +to build Emacs once on, say, a Unix system and transfer that directory +to the Mac. Note that linefeed conversion must be disabled when +transferring compiled Lisp files. + +An alternative is to unzip and untar the archive lisp-elc.tgz. An +older version of frame.elc in the archive may cause a problem when the +Mac version starts up. If this is the case, simply remove or rename +that file. Then once Emacs runs, you can invoke +byte-recompile-directory on the lisp directory to byte-compile all +out-of-date Lisp files. + +You may also need to run update-autoloads-from-directories on the lisp +directory to bring loaddefs.el up-to-date. + +* NOTES + +Emacs should build and run on a PowerMac running Mac OS 8.1 - 9.0. + +You will need around 100 MB of disk space for the source files and +intermediate files. + +It will not run on machines with more than 256 MB of physical or +virtual memory. + +Currently there is no support for building the LEIM directory on the +Mac.
