How To Override FrontEnd/init.m Settings?
$Version = 5.0 for Microsoft Windows (November 18, 2003) $Host = Windows XP Pro, Version 5.1 Mathgroup: When a change is made to the OptionBrowser, it is stored in $UserBaseDirectory/FrontEnd/init.m. My normal Magnification = 1.66. To determine how $UserBaseDirectory/FrontEnd/init.m settings could be overridden by a new user's FrontEnd/init.m settings, I placed the override SetOptions[ $FrontEnd, Magnification->3 ] into an init.m file, and tried using it in all the FrontEnd/init.m and Kernel/init.m file initialization options described in MathBook's File Layout > Front End, Kernel, and Configuration sections. No matter where I put this new init.m file, Mathematica gives a load error beep, and prints SetOptions::optnf: Magnification is not a known option for $FrontEnd. However, if I move this init.m file to $InstallationDirectory, AND change its name from init.m to just "x" (no file extension), and relaunch Mathematica, I get a normal Untitled-1 notebook with my default font. Into this notebook I type << x and Mathematica accepts the one line "SetOptions[ $FrontEnd, Magnification->3 ]" without complaint, and instantly changes the system's font size to 300% magnification. This series of experiments brings me to the following conclusion. Suppose I have several Mathematica users on the same machine, each of whom wants a different set of FrontEnd settings overrides and Kernel customizations. For simplicity, I would like to tell them we need only put what they want into _one_ file in $InstallationDirectory, which we'll name with each user's unique 3 initials (say jmb). Then all they have to do when the Untitled-1 notebook appears is type << jmb <Num-Enter> and Mathematica will accept all their FrontEnd overrides and Kernel customizations. What really bothers me is that I've found no simple way to make Mathematica accept FrontEnd command overrides when I follow the FrontEnd/init.m directions given in the Mathematica 5.0 Book. Does anyone have some different or additional thoughts on this issue? - Harold
