3. Getting Started

This chapter describes what the hardware and software requirements are to run MUIbase on your computer, the procedure for installing and updating MUIbase, and how to start and quit MUIbase.

3.1 Installing MUIbase on Windows

MUIbase 3.x for Windows runs on Intel compatible computers that use the Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10 operating system. Starting with MUIbase version 4.0, Windows 7 or better is required.

The MUIbase installer is distributed as a Windows executable, e.g. `MUIbase-4.0-setup.exe' which you can download from the MUIbase home page When running the installer, you will be asked several options about where to install MUIbase and which configuration to use. In case you have a previous MUIbase version installed on your computer, the installation procedure allows to update it to the new version.

After a successful installation your Windows `Start' menu should contain a new entry for launching MUIbase. You can now remove the MUIbase installer as it is no longer needed.

3.2 Installing MUIbase on Mac OS

MUIbase for Mac OS supports Mac OS X Lion (10.7) and later versions of the Mac OS X operating system. The software is distributed as a 64bit Intel binary.

A disk image of MUIbase, e.g. `MUIbase-4.0-Lion.dmg' can be downloaded from the MUIbase home page After downloading and opening the image, drag and drop `' into your computer's `Applications' folder.

3.3 Installing MUIbase on Linux

You can install and run MUIbase on an Intel-compatible computer running the Linux operating system.

MUIbase for Linux is distributed both, as a Debian package (e.g. `muibase_4.0_ubuntu_trusty_amd64.deb' for Ubuntu or Debian) and as an RPM archive (e.g. `MUIbase-4.0-fc21.x86_64.rpm' for Fedora).

There are separate versions for the 32bit architecture, e.g. `muibase_4.0_ubuntu_trusty_i386.deb' and `MUIbase-4.0-fc21.i686.rpm'. All versions can be downloaded from the MUIbase home page

Usually MUIbase installs or updates itself automatically after downloading it on your computer. In case the installation process does not start automatically, the following commands executed as super user (root) in a command shell install or update MUIbase on a Debian-based Linux computer:

dpkg --install muibase.deb
apt-mark hold muibase.deb

where muibase.deb is the downloaded MUIbase Debian package.

On a Redhat-based system (RPM), the commands are:

rpm -Uvh MUIbase.rpm

where MUIbase.rpm is the downloaded RPM archive.

After a successful installation you should see a new menu item in the `Applications - Office' menu tree of your (Gnome or KDE) desktop. At this time the downloaded archive is no longer necessary and can be removed.

NB: On Debian-based systems you need to hold the package otherwise the next update of your system will remove it because it's not installed from a source defined in the repository list `/etc/apt/source.list'.

3.4 Installing MUIbase on Amiga

MUIbase for Amiga runs on Amiga OS version 3.0 or higher and requires an 68020 processor or better. Furthermore, MUI version 3.8 or higher must be present on your system. A minimum of 4MB RAM and 10MB of free hard disk space are needed. The m68k binary of MUIbase for Amiga has been reported to run stable on UAE, MorphOS and Amiga OS4. PowerPC binaries for MorphOS and Amiga OS4 are also available as part of the distributed archive. A separate distribution contains an AROS version.

MUIbase is distributed as an lha archive, e.g. `MUIbase-3.0.lha' and can be downloaded from the MUIbase home page In order to install MUIbase on your computer unpack this archive to a temporary directory. Do not unpack it to the target directory!

Double click the MUIbase installer script `Install-MUIbase' and follow its instructions. The script asks for a directory where the software should be copied to. Do not enter the directory where you have unpacked the MUIbase archive to. The script is also capable of updating an existing MUIbase installation by entering the directory where you previously installed MUIbase.

After successful installation you will find a (new) drawer on your system containing the MUIbase program along with all necessary files and some sample projects. In addition an assign `MUIbase:' referring to this drawer has been added to your system file `S:User-Startup'. It is safe to remove the lha archive and the temporary files as they are no longer needed.

3.5 Updating from a Previous Version

When installing MUIbase, you can upgrade from a previous version of MUIbase or reinstall it as described above. During the new installation, all necessary files are replaced by new ones. This includes the sample projects in the `Demos' directory. It is therefore not recommended to place your own projects into this directory nor to use any of the sample projects for managing your own data as they are overwritten when reinstalling or upgrading MUIbase.

The recommended way to manage your own projects is to place them into a separate directory independent of the MUIbase installation directory.

3.6 Starting MUIbase

MUIbase can be started either from your graphical environment or from a command shell. On Windows you find MUIbase under the `Start' menu. On Mac OS, you launch MUIbase using `Finder' from the `Applications' directory. If you are running Gnome or KDE on Linux, you can start MUIbase by choosing the corresponding item from the `Applications - Office' menu. On the Workbench (Amiga) you double click the MUIbase icon or the icon of a MUIbase project which is then automatically loaded after starting MUIbase (you can also select several MUIbase projects by shift clicking them and double clicking the last one).

When starting MUIbase from a command shell on Windows, Linux or Amiga you can include command line arguments and optional projects to load. There are two basic ways to start MUIbase from a command shell:

MUIbase [project1 ...]
MUIbase -n

The first form starts MUIbase and loads the optional projects specified by their filenames project1 .... The second form starts MUIbase without graphical user interface. This can be useful for running MUIbase as a server in the background and accessing it through its external interface (e.g. ARexx on Amiga, see ARexx interface).

3.7 Quitting MUIbase

To quit MUIbase select menu item `Project - Quit' or close all opened projects.

3.8 Filename Conventions on Windows, Mac OS and Linux

MUIbase for Windows, Mac OS and Linux has a few special conventions for filenames that are usually not found in other software on those systems.

When MUIbase is starting, an environment variable `MUIbase' is set referring to the installation directory of MUIbase. On Windows this is the directory specified during the software installation. On Mac OS, it is directory `/Applications/'. On Linux, it is directory `/usr/share/MUIbase'.

When interpreting filenames (either entered by the user or the filenames present in this documentation) a filename is examined for the occurrence of environment variables. If a filename contains a dollar sign `$' then the characters following it until the first non-alpha-numeric character are interpreted as an environment variable and, if the environment variable is set, the part of the filename is replaced by the contents of the environment variable (otherwise the part of the filename is left unchanged including the `$' sign). You can use parentheses around the environment variable if it contains non-alpha-numeric characters. For example `$HOME/data' expands to the path where `$HOME' has been replaced with the path name of your home directory.

Furthermore, Amiga-style `assign names' are handled in the following way. If a filename contains a colon `:' then everything before the colon is treated like an environment variable (called `assign name') and is replaced by its contents if the environment variable is set. `Assign names' should be at least 2 characters in length, in order to distinguish them from drive letters on Windows.

These conventions allow, for example, to refer to the movie sample database inside the MUIbase installation directory as `MUIbase:demos/Movie.mb'.

Another example is when you set an environment variable, say `EXTERNAL_DATA', referring to the directory where you store external data like images, etc. of one of your projects. You can then access data inside this directory through `EXTERNAL_DATA:some-file' and store such filenames in the database project.
