- 1. INTRODUCTION.
-
- This is the README file from the distribution of Ada/Ed version
- 1.11.0a, an Ada interpreter for Unix-based machines. The distribution
- consists of one directory packaged into a compressed tar file available
- through anonymous ftp on cs.nyu.edu (128.122.140.24) in the directory
- pub/adaed. The distribution contains all sources, documentation, the
- Makefile, and some shell scripts used in building Ada/Ed. The ftp
- directory contains another distribution for 386/DOS machines.

-
- Ada/Ed is a translator-interpreter for Ada. It is intended as a teaching
- tool, and does not have the capacity, performance, or robustness of
- commercial Ada compilers. Ada/Ed was developed at New York University, as
- part of a long-range project in language definition and software prototyping.
- The project produced the first validated translator for Ada, in the form of
- an executable definition of the language written in SETL. The SETL system
- served as design document and prototype for the C version being released today.
-
- Ada/Ed was last validated under version 1.7 of the ACVC tests. Therefore it is
- not currently a validated Ada system, and users can expect to find small
- discrepancies between Ada/Ed and currently validated compilers.
-
- Apart from the 100-odd tests of ACVC 1.11 that Ada/Ed currently fails, the
- major deficiency of the system is that, being an interpreter, it does not
- implement most representation clauses, and thus does not support systems
- programming close to the machine level.
-
- We trust that even with these limitations, Ada/Ed will be of use to the
- Ada community at large: students, educators, user, and implementors. The
- sources of the system should be of interest to compiler writers, and we hope
- that they will encourage the construction of software tools to make the system
- more usable and polished. The NYUADA project does not have the resources to
- promise regular new maintenance releases of the software, but will do its
- best to keep track of reported errors, workarounds, and fixes. We will also
- produce at irregular intervals design notes and additional documentation on
- the front-end of the system. We urge users to send comments, corrections
- and bug reports (reduced to their simplest form!) to: adaed@cs.nyu.edu
-
-
- All users of Ada/Ed are urged to register themselves by
- sending email to the above address, or to the NYUADA project, New
- York University, 251 Mercer Street, New York, NY 10012. This will allow us to
- notify users of updates and new releases of the system.

- 3. INSTALLATION
-
-
- The directory contains C language source files, a Makefile, shell scripts
- used in building the system, and documentation.
-
- To install:
-
- 1. Edit the Makefile. The installation of Ada/Ed puts top level
- executables in a directory that should be on users' PATH, and
- other executables called by the driver plus predefined ada
- library files are placed into a library directory. The makefile
- macros BINDIR and LIBDIR should be defined to name these
- directories. The makefile comes with gcc specified as the
- C compiler, which is the only one that it has actually been
- built with. An ANSI C compiler is certainly needed. Edit
- MANDIR for the location of man pages.
-
- 2. Look at the file config.h and determine if the symbols specifying
- word length and alignment will be set properly.
-
- 3. Build it. 'make install' will do everything; otherwise do
- 'make', 'make predef', and 'make install'.
-
- 4. Read the man pages for adaed and enjoy it.
