Welcome to the Seed7 Homepage

Seed7 is a general purpose programming language designed by Thomas
Mertes. It is a higher level language compared to Ada, C/C++ and
Java. The Seed7 interpreter and the example programs are open-source
software. There is also an open-source Seed7 compiler. The compiler
translates Seed7 programs to C programs which are subsequently
compiled to machine code.

In Seed7 new statements and operators can be declared easily.
Functions with type results and type parameters are more elegant than
a template or generics concept. Object orientation is used where it
brings advantages and not in places where other solutions are more
obvious. Seed7 contains several concepts from Pascal, Ada, C, C++ and
Java.

Features of Seed7

  * As an extensible programming language it supports user defined
    statements and operators.
  * Types are first class objects (Templates and generics can be
    defined easily without special syntax).
  * Predefined constructs like arrays or for-loops are defined in
    libraries.
  * Object orientation supports interfaces and multiple dispatch.
  * Static type checking and the absence of automatic casts help to
    find errors at compile-time.
  * There is an automatic memory management that works without a
    garbage collection process.
  * Exception handling and source code debugging are supported.
  * If an integer computation overflows the exception OVERFLOW_ERROR
    is raised.
  * Numbers which have unlimited size are provided with the types
    bigInteger and bigRational.
  * Functions, operators and statements can be overloaded.
  * There are various predefined types like array, hash, set, struct,
    color, time, duration, etc.
  * Seed7 programs are source code portable without any need to
    change the code.
  * Seed7 provides a database independent API, which can connect to
    MySQL, MariaDB, SQLLite, PostgreSQL, Oracle, ODBC, Firebird,
    Interbase, Db2, Informix and SQL Server databases.
  * Seed7 runs under Linux, various Unix versions and Windows.
  * The interpreter and the example programs use the GPL license,
    while the runtime library uses the LGPL license.
