the Dartmouth Environment Elementary Renderer
the Dartmouth Environment Elementary Renderer, a set of
programs for emulating the original Dartmouth DCTS system, the same on
which the first BASIC compiler was written in 1964. deer at present is composed of two programs:
The ALGOL interpreter is under conception.
- the DCTS Operating System Emulator, written in
bash and thus
working on any UNIX or UNIX-like modern system. This engine is named deer, of course.
- the BASIC interpreter (yes, interpreter, I cannot write a
compiler yet), written in C, and emulating version III of the Original
Dartmouth BASIC language of 1966. The interpreter is named dib (which
means Dib Is Basic) and, as a standalone executable, may be used even
outside of the deer
Available documentation (which is contained into the downloadable
package and is linked here for your convenience):
- The deer manual
(written with gvim in text form, notes upon the Operating System: how to
write, save, execute and manage your files and programs)
- The dib manual
(written with gvim in text form, notes about the dib BASIC
Dartmouth BASIC versions and The dib BASIC
'concise' (a pdf written with NeoOffice; at page 1 all the BASIC versions are drafted, each one with
its specific features, and at page 2 dib's standard and extended features are summarized)
- The BASIC primer (written with gvim in text form, notes about BASIC programming) [not yet ready]
bash script may be executed anywhere, provided you put it
into a directory contained into the PATH; the dib executable,
before use, must be compiled and installed. I suggest the following
(easy) procedure in 4 steps:
1) Copy the package somewhere, and unpack it using tar:
$ tar zxvf deer.1.0.beta.tgz
$ cd distrib/
now, choose a directory into your path, where executables will be saved; let's assume it's ~/bin (that is subdirectory /bin in your Home directory, but you can choose any).
2) edit the
Makefile to customize addresses for dib (e.g., among the rest, change the install directory to ~/bin, commenting the undesired destinations and leaving uncommented ONE ONLY valid destination).
3) type the following (be sure to have gcc
installed - Note:
I compiled dib under gcc 4.X, I believe all 3.X versions will work, and
I hope even version 2.95 will work, but I don't guarantee it):
(the latter may require root privileges
if you try to install dib into system directories).
For Mac Users:
in case you want to install dib into some system directory (e.g. /user/local/bin), remember that
privileges are not required, as long as you can access an
administrative login: in this case, after make, login as an administrator with
(being <name> the username
of the administrator) - you will be requested of a password - and then
install the software with
$ sudo make install
4) now type the following (if you want):
$ deer --help
$ dib --help
to learn the basic facts, and you're done! If you please, copy the USER
directory (contained in the distrib/ directory) to your home deer directory (which is located under $HOME/.deer). There you will find many examples, ready to be run.
wrote both programs on Mac OS X 10.4.X, so I expect some
differences with Linux and/or Unix machines.
Version 1.0.beta (Dec. 06, 2008)
Download it here.
- This is the first uploaded version.
I wait for your impressions and bugs. Version 1.0 final
will be the version you and I will build together from this beta
version. Send me your suggestions, your considerations, your
corrections; even send me your working BASIC programs for dib,
all commented and completed with your own name and data (and six
characters per name): they will be part of the next package, of course.
It's GPL! Enjoy!
