Seed7 05.20141019

An open source and free programming language that enables users to transform programs from Seed 7 to C++ programs and subsequently transformed compiled to machine code.
Seed7 is a general purpose programming language designed by Thomas Mertes. The Seed7 interpreter and the example programs are open-source software. There is also an open-source Seed7 compiler. The compiler compiles 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.

Main features:

  • 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 declared in the language itself.
  • Object orientation with interfaces and multiple dispatch.
  • Static type checking and no automatic casts.
  • Support for bigInteger and bigRational numbers which have unlimited size.
  • exception handling
  • overloading of procedures/functions/operators/statements
  • Various predefined types like resizable arrays, hashes, bitsets, structs, color, time, duration, etc.
  • 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.

What's New in This Release:
  • The compiler s7c has been improved to process the semicolon operator with reduced stack usage. Thanks go to Pietro Cerutti for pointing out problems with the available stack size under FreeBSD.
  • In drw_x11.c the function redraw has been improved to ignore expose events when backing store is active. Thanks go to Brian Callahan for reporting problems with activated backing store under OpenBSD.
  • The library makedata.s7i has been improved. Now conditional makefile parts with ifdef and ifndef are allowed. Now it is possible to use the ?= operator to assign a value to a variable. Now the value of a variable is taken from the environment, when it has not been defined in the makefile.
  • The function setupStack has been moved from cmd_rtl.c to heaputl.c.
