WELCOME TO THE WORLD OF SEED7
=============================
This are the release notes to the Seed7 package. Read them
carefully, as they tell you what this is all about and in
which files the rest of the information is.
WHAT IS SEED7?
Seed7 is a general purpose programming language. It is a
higher level language compared to Ada, C++ and Java. In Seed7
new statements and operators can be defined easily. Functions
with type results and type parameters are more elegant than
the usual template or generics concept. Object orientation is
used when it brings advantages and not in places when other
solutions are more obvious. Although Seed7 contains several
concepts of other programming languages it cannot be seen as
direct descendant of another programming language. To get a
general overview over the language read: doc/manual.txt
(Chapter: Introduction).
WHAT IS CONTAINED IN THIS PACKAGE?
The Seed7 package contains the Seed7 interpreter in source
besides documentation files, include files and program
examples. The following subdirectories exist:
src The source of the interpreter
prg Program examples
lib Include files
doc Documentation files
bin Executables and runtime libraries
Using the extension several files can be distinguished:
*.txt Documentation files
*.sd7 Program example files
*.s7i Include files
*.dna Include file for the dna program
*.c C source file
*.h C include file
HOW TO COMPILE THE INTERPRETER?
For Linux this is quite simple (to compile under other
operating systems see 'seed7/src/read_me.txt'). The 'makefile'
is prepared for Linux. First make sure that gcc, make and the
development packages for X11 and ncurses are installed. Then
go to the 'src' directory and type:
make depend
make
After the compilation the interpreter is linked to the file
'seed7/prg/s7'. The Seed7 compiler (s7c) is compiled with:
make s7c
The file 'seed7/src/read_me.txt' contains a detailed
explanation of the compilation process.
HOW TO COMPILE UNDER OTHER OPERATING SYSTEMS?
Seed7 supports several operating systems such as Windows,
Mac OS X and various Unix variants. How to compile under
this operating systems is explained in the file
'seed7/src/read_me.txt'.
HOW TO EXECUTE A PROGRAM?
After compiling the interpreter you can make the first test.
Switch to the 'prg' directory and type:
./s7 hello
This executes the hello world program which is in the
'hello.sd7' file. Every file with the '.sd7' extension can be
executed with the 's7' interpreter.
A list of the program files with a short description can be
found in the file: prg/files.
WHAT TO DO WHEN THERE ARE PROBLEMS WITH THE COMPILATION?
There is a read_me.txt file in the seed7/src directory which
discusses the compilation process with more detail.
HOW TO SEND A PATCH?
If you want to participate, you are always welcome.
I would be glad to receive patches in the unified diff format:
diff -urN oldseed7dir/ newseed7dir/ > patch.diff
If you send a patch, it is assumed that this patch is released
under the GPL (or LGPL for libraries) license.
Greetings Thomas Mertes
