Most computers running Linux, Unix and MAC have the Python interpreter language already installed, including the Raspberry Pi.
You can simply check if this is true by typing the command python3 in a terminal.
If it is installed you'll see the Python version printed followed by the Python prompt >>>.
You may exit the Python interpreter again by typing Ctrl-D.
If it is not installed you need to install the Python programming language first, before you continue installing the SB-Assembler version 3. The SB-Assembler needs at least Python version 3.2 in order to run. If yours is older than 3.2, try to upgrade first.
You may choose to install the SB-Assembler for the current user only (easiest), or system wide for all users. Usually it will be sufficient to install it for the current user only. Simply start by unpacking all files from the download package into a temporary directory.
Don't worry about the amount of text on this page. It's not difficult, as long as you follow the instructions. I'll direct you through the installation process, step by step.
For an installation for the current user only, copy the file sbasm and the entire directory sbapack into the directory ~/bin .
For the less experienced Linux users, the ~/bin directory is the directory /home/you/bin, where you is the user name you used during login.
If the directory ~/bin doesn't exist, create it before copying the files into it.
Ubuntu will automatically add the directory ~/bin to your PATH, the next time you start a new bash shell.
If your Linux/Unix version doesn't do that, include ~/bin yourself to the PATH variable in your ~/.profile file.
Different shells have different ways to add a directory to the PATH, Google is your friend if you use another shell than bash.
All remaining directories from the unpacked zip file can be copied into your projects directory. If you don't have one, create one in a convenient place, wherever you like.
You can throw away the one remaining file sbasm.py, which is only used by Microsoft users.
System wide installation of the SB-Assembler requires you to be able to become the super user, or root.
The process is much the same as for single user installations.
The main difference is the destination of the file sbasm and the directory sbapack.
They can be copied to the directory /usr/bin, which requires root privileges.
Make sure everyone has the right to execute the file sbasm and has read access to all the files in the directory sbapack.
All other directories from the distribution package go, like before into your project directory, wherever you like that to be. There's no need to do that as super user, or root. If all users are interested in having these files at hand you could copy these directories to a shared directory.
In order to speed up startup times, and hence execution times, it is also recommended to pre-compile all the files inside in the directory sbapack. Normally this process is done whenever you run a program for the first time. However this will fail on a system wide installation because a simple mortal doesn't have the rights to write the .pyc files to a system directory.
The following instructions will do that for you:
cd /usr/bin/sbapack sudo ./precompile.sh
Final note: On most systems the python interpreter can be found in the directory /usr/bin/.
However, on some systems (e.g. FreeBSD) the python interpreter is located in /usr/local/bin/.
In that case you will have to change the first line of the sbasm file so that it points to the proper directory.
The same is true for the first line of the precompile.sh script, if you need that for system wide installation.
If you don't know where the python interpreter is located on your system, simply type which python3 in a shell and the system will tell you where it is located.
Installing newer releases of the SB-Assembler requires you to overwrite existing files with the newer versions. And don't forget to run the pre-compile script if you've installed your copy to the /usr/bin directory.
Windows doesn't come standard with a Python interpreter.
You can simply download it from www.python.org/download/.
There you can download version 3.2 or higher for your Windows version, which is usually the first link you can click on on the download page.
After downloading the file you can start it. Simply accept all default settings the installer proposes, especially you'll want the "Install launcher for all users" option.
That way running the SB-Assembler will automatically invoke the proper Python version, just in case you have more than one version installed.
Now it's time to download the SB-Assembler package, if you haven't done so already.
After that you can unpack it all into a temporary directory of your choice.
Then you can move the file sbasm.py and the entire directories sbapack, headers and opcodes into a newly created directory placed wherever you prefer (e.g. C:\sbasm3). The remaining directories can be copied into your projects directory, wherever you like.
If you are upgrading from a previous install, simply overwrite all old files with the new ones by repeating the process above.
Remember where you've put the file sbasm.py. Now add the directory containing the sbasm.py file to your system's path. A step by step guide on how to do this for Windows 7, 8 and 10 can be found by following this link.
The SB-Assembler doesn't really require an installation process. All you need to do is copy some files into the right locations. But I can give you some tips to make life as comfortable as possible while working with the SB-Assembler.
Don't worry about your projects when updating the assembler after a previous installation. Only the original files from the download package will be overwritten by a new version or the same version. Your own work will be unaffected.
Please note that I am not suggesting that you don't have to make backup copies of your work!
