Sure!

First of all, you need to set up you PATH so that it is available to
graphical programs too, otherwise your TeXmacs won't even start.

Paste the following lines into a terminal:

mkdir ~/.MacOSX && cat > ~/.MacOSX/environment.plist << EOF
<plist version="1.0">
  <dict>
    <key>PATH</key>
    <string>$PATH</string>
  </dict>
</plist>
EOF

If it fails, complaining that the file already exists, then you should
manually merge your current PATH into it by means of a text editor.

In any case you need to log out and log back in for it to take effect.


Then create the application wrapper:

- Download Platypus http://www.sveinbjorn.org/platypus/
- Open it and type TeXmacs as the Application Name
- Open www.texmacs.org in Safari (other browsers won't work here) and
  drag the Gnu image into Platypus' icon drop box
- Make sure the script type is set to Shell and click New
- Paste the following and click Save:

------------------------------------------------------------------------
#!/bin/sh

CWD="`dirname \"$0\"`"
TMP=/tmp/$UID/TemporaryItems

mkdir -p $TMP
cat >"$TMP/getdisplay.sh" <<EOF
#!/bin/sh

if [ "$DISPLAY"x == "x" ]; then
    echo :0 > /tmp/$UID/TemporaryItems/display
else
    echo $DISPLAY > /tmp/$UID/TemporaryItems/display
fi
EOF
chmod 755 "$TMP/getdisplay.sh"

rm -f $TMP/display
open-x11 $TMP/getdisplay.sh || \
open -a XDarwin $TMP/getdisplay.sh || \
echo ":0" > $TMP/display

while [ "$?" == "0" -a ! -f $TMP/display ]; do sleep 1; done
export "DISPLAY=`cat $TMP/display`"

ps -wx -ocommand | grep -e '[X]11' > /dev/null || exit 11

cd ~/
exec texmacs
------------------------------------------------------------------------

(borrowed from Gimp.app by the way)

- Click Create and save as "TeXmacs"

Now you can double-click it to launch TeXmacs (opening X11 if needed),
put it in the dock, click-and-hold it and choose Quit, and the black
triangle in the dock will tell you if TeXmacs is currently running!

Alas, other things won't work, such as hiding it or bringing it to the
foreground, because TeXmacs's window itself belongs to the X11 app.
(Therefore you can do those things on the X11 icon.)


If your X11 spawns a spurious XTerm every time it starts and you don't
like it, you can paste the following lines into a terminal:

cat > ~/.xinitrc << EOF
xrdb -merge /etc/X11/xinit/.Xresources
xmodmap /etc/X11/xinit/.Xmodmap
xrdb -merge ~/.Xresources
xmodmap ~/.Xmodmap
exec quartz-wm
EOF

Of course! Just change the last line of the Platypus script above to:

exec xterm -e texmacs
