@section Windowing System Events in Mac OS X
|
||||
|
||||
Nextstep applications receive a number of special events which have
|
||||
no X equivalent. These are sent as specially defined ``keys'', which
|
||||
do not correspond to any sequence of keystrokes. Under Emacs, these
|
||||
``key'' events can be bound to functions just like ordinary
|
||||
keystrokes. Here is a list of these events.
|
||||
@subsection Grabbing environment variables
|
||||
|
||||
@table @key
|
||||
@item ns-open-file
|
||||
@vindex ns-pop-up-frames
|
||||
This event occurs when another Nextstep application requests that
|
||||
Emacs open a file. A typical reason for this would be a user
|
||||
double-clicking a file in the Finder application. By default, Emacs
|
||||
responds to this event by opening a new frame and visiting the file in
|
||||
that frame (@code{ns-find-file}), As an exception, if the selected
|
||||
buffer is the @samp{*scratch*} buffer, Emacs visits the file in the
|
||||
the selected frame.
|
||||
Many programs which may run under Emacs like latex or man depend on the
|
||||
settings of environment variables. If Emacs is launched from the shell, it
|
||||
will automatically inherit these environment variables and its subprocesses
|
||||
will inherit them from it. But if Emacs.app is launched from the Finder it
|
||||
is not a descendant of any shell, so its environment variables haven't been
|
||||
set which often causes the subprocesses it launches to behave differently than
|
||||
they would when launched from the shell.
|
||||
|
||||
You can change how Emacs responds to @key{ns-open-file} by changing
|
||||
the variable @code{ns-pop-up-frames}. Its default value,
|
||||
@code{'fresh}, is what we have just described. A value of @code{t}
|
||||
means to always visit the file in a new frame. A value of @code{nil}
|
||||
means to always visit the file in an existing frame.
|
||||
To solve this problem for Emacs.app, there are two solutions. First is to
|
||||
run, from the command line:
|
||||
|
||||
@item ns-open-temp-file
|
||||
This event occurs when another application requests that Emacs open a
|
||||
temporary file. By default, this is handled by just generating a
|
||||
@code{ns-open-file} event, the results of which are described above.
|
||||
@example
|
||||
.../Emacs.app/Contents/MacOS/bin/mac-fix-env
|
||||
@end example
|
||||
|
||||
You can bind @key{ns-pop-up-frames} and @key{ns-open-temp-file} to
|
||||
other Lisp functions. When the event is registered, the name of the
|
||||
file to open is stored in the variable @code{ns-input-file}.
|
||||
This will pick up your environment settings and save them into a special file
|
||||
@file{~/.MacOSX/environment.plist}, which the desktop environment will use to
|
||||
set the environment for all launched applications. The drawback of this
|
||||
method is it needs to be run again whenever something changes.
|
||||
|
||||
@item ns-open-file-line
|
||||
Some applications, such as ProjectBuilder and gdb, request not only a
|
||||
particular file, but also a particular line or sequence of lines in
|
||||
the file. Emacs handles this by visiting that file and highlighting
|
||||
the requested line (@code{ns-open-file-select-line}).
|
||||
The other approach is to use the @code{ns-grabenv} command inside Emacs. This
|
||||
function will run a subshell and copy its environment variables into Emacs.
|
||||
|
||||
@item ns-drag-file
|
||||
This event occurs when a user drags files from another application
|
||||
into an Emacs frame. The default behavior is to insert the contents
|
||||
of all the dragged files into the current buffer
|
||||
(@code{ns-insert-files}). The list of dragged files is stored in the
|
||||
variable @code{ns-input-file}.
|
||||
Adding this line to your @file{~/.emacs} will grab the csh environment
|
||||
whenever emacs runs under a window system.
|
||||
|
||||
@item ns-drag-color
|
||||
This event occurs when a user drags a color from the color well (or
|
||||
some other source) into an Emacs frame. The default behavior is to
|
||||
alter the foreground color of the area the color was dragged onto
|
||||
(@code{ns-set-foreground-at-mouse}). If this event is issued with a
|
||||
@key{Shift} modifier, Emacs changes the background color instead
|
||||
(@code{ns-set-background-at-mouse}). The name of the dragged color is
|
||||
stored in the variable @code{ns-input-color}.
|
||||
@lisp
|
||||
(if window-system (ns-grabenv))
|
||||
@end lisp
|
||||
|
||||
@item ns-change-font
|
||||
This event occurs when the user selects a font in a Nextstep font
|
||||
panel (which can be opened with @kbd{Cmd-t}). The default behavior is
|
||||
to adjust the font of the selected frame
|
||||
(@code{ns-respond-to-changefont}). The name and size of the selected
|
||||
font are stored in the variables @code{ns-input-font} and
|
||||
@code{ns-input-fontsize} respectively.
|
||||
If you have a different shell you will have to give @code{ns-grabenv} some
|
||||
arguments. For zsh you would do this.
|
||||
|
||||
@item ns-power-off
|
||||
This event occurs when the user logs out and Emacs is still running.
|
||||
The default behavior is to save all file-visiting buffers without
|
||||
confirmation, and exit.
|
||||
@end table
|
||||
@lisp
|
||||
(if window-system (ns-grabenv "/usr/bin/zsh"
|
||||
"source /etc/zshenv"
|
||||
"source ~/.zshenv"))
|
||||
@end lisp
|
||||
|
||||
Emacs also allows users to make use of Nextstep services, via a set
|
||||
of commands whose names begin with @samp{ns-service-} and end with the
|
||||
name of the service. Type @kbd{M-x ns-service-@key{TAB}@key{TAB}} to
|
||||
see a list of these commands. These functions either operate on
|
||||
marked text (replacing it with the result) or take a string argument
|
||||
and return the result as a string. You can also use the Lisp function
|
||||
@code{ns-perform-service} to pass arbitrary strings to arbitrary
|
||||
services and receive the results back. Note that you may need to
|
||||
restart Emacs to access newly-available services.
|
||||
The reason that @code{ns-grabenv} is not done by default is that it adds up
|
||||
to a second or two to the Emacs startup time.

an Emacs frame. Holding down shift will change the background color
|
||||
instead of the foreground.
|
||||
The Color panel, brought up by the @samp{Colors...} button, allows setting of
|
||||
foreground or background of any face. Drag from the color bar to over the
|

@item
|
||||
To change the line height that text is displayed at drag the Expand

Line Spacing slider. When the slider is set to 0.0 Emacs will use the
|
||||
same line height as other Mac OS X applications. To increase the line
|
||||
height (and decrease the number of lines that can be displayed on the
|
||||
screen) drag the slider towards 1.0. To decrease the line height
|
||||
(increases the number of lines that can be displayed) drag the slider
|
||||
towards -1.0.
|
||||
The @samp{Expand Line Spacing} slider controls vertical spacing of text. The
|
||||
0.0 setting corresponds to the same height as other applications. Settings
|
||||
less than 0 compress the spacing, and greater than 0 expand it. Emacs must be
|
||||
restarted for the new setting to take effect.
|
||||
|
||||
After the line spacing setting has been changed Emacs must be restarted
|
||||
to take account of the change.

buffer is the @samp{*scratch*} buffer, Emacs visits the file in the
|
||||
the selected frame.
|
||||
|
||||
You can change how Emacs responds to @key{ns-open-file} by changing
|
||||
the variable @code{ns-pop-up-frames}. Its default value,
|
||||
@code{'fresh}, is what we have just described. A value of @code{t}
|
||||
means to always visit the file in a new frame. A value of @code{nil}
|
||||
means to always visit the file in an existing frame.
|
||||
|
||||
@item ns-open-temp-file
|
||||
This event occurs when another application requests that Emacs open a
|
||||
temporary file. By default, this is handled by just generating a
|
||||
@code{ns-open-file} event, the results of which are described above.
|
||||
|
||||
You can bind @key{ns-pop-up-frames} and @key{ns-open-temp-file} to
|
||||
other Lisp functions. When the event is registered, the name of the
|
||||
file to open is stored in the variable @code{ns-input-file}.
|
||||
|
||||
@item ns-open-file-line
|
||||
Some applications, such as ProjectBuilder and gdb, request not only a
|
||||
particular file, but also a particular line or sequence of lines in
|
||||
the file. Emacs handles this by visiting that file and highlighting
|
||||
the requested line (@code{ns-open-file-select-line}).
|
||||
|
||||
@item ns-drag-file
|
||||
This event occurs when a user drags files from another application
|
||||
into an Emacs frame. The default behavior is to insert the contents
|
||||
of all the dragged files into the current buffer
|
||||
(@code{ns-insert-files}). The list of dragged files is stored in the
|
||||
variable @code{ns-input-file}.
|
||||
|
||||
@item ns-drag-color
|
||||
This event occurs when a user drags a color from the color well (or
|
||||
some other source) into an Emacs frame. The default behavior is to
|
||||
alter the foreground color of the area the color was dragged onto
|
||||
(@code{ns-set-foreground-at-mouse}). If this event is issued with a
|
||||
@key{Shift} modifier, Emacs changes the background color instead
|
||||
(@code{ns-set-background-at-mouse}). The name of the dragged color is
|
||||
stored in the variable @code{ns-input-color}.
|
||||
|
||||
@item ns-change-font
|
||||
This event occurs when the user selects a font in a Nextstep font
|
||||
panel (which can be opened with @kbd{Cmd-t}). The default behavior is
|
||||
to adjust the font of the selected frame
|
||||
(@code{ns-respond-to-changefont}). The name and size of the selected
|
||||
font are stored in the variables @code{ns-input-font} and
|
||||
@code{ns-input-fontsize} respectively.
|
||||
|
||||
@item ns-power-off
|
||||
This event occurs when the user logs out and Emacs is still running.
|
||||
The default behavior is to save all file-visiting buffers without
|
||||
confirmation, and exit.
|
||||
@end table
|
||||
|
||||
Emacs also allows users to make use of Nextstep services, via a set
|
||||
of commands whose names begin with @samp{ns-service-} and end with the
|
||||
name of the service. Type @kbd{M-x ns-service-@key{TAB}@key{TAB}} to
|
||||
see a list of these commands. These functions either operate on
|
||||
marked text (replacing it with the result) or take a string argument
|
||||
and return the result as a string. You can also use the Lisp function
|
||||
@code{ns-perform-service} to pass arbitrary strings to arbitrary
|
||||
services and receive the results back. Note that you may need to
|
||||
restart Emacs to access newly-available services.
