Seed7 is a general purpose programming language designed by Thomas Mertes. Seed7 project is a higher level language compared to Ada, C/C and Java.
The Seed7 interpreter and the example programs are open-source software. An open-source Seed7 compiler is also under development.
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.
Although Seed7 contains several concepts of other programming languages it is generally not considered as a direct descendant of any other programming language.
Here are some key features of "Seed7":
· 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
· Strong typing
· exception handling
· overloading of procedures/functions/operators/statements
· Various predefined types like resizable arrays, hashes, bitsets, structs, color, time, duration, etc.
· Runs under linux and various unix versions. A windows version is under developent
· The interpreter and the example programs use the GPL license, while the runtime library uses the LGPL license.
What's New in This Release: [ read full changelog ]
· The compiler (comp.sd7) was improved to support the actions CMD_GET_CTIME and TIM_FROM_TIMESTAMP.
· The handling of the actions ARR_ARRLIT, ARR_IDX, and DRW_OPEN in the compiler was improved.
· The interpreter (hi) and the compiler were improved to support the actions STR_PUSH, TIM_SET_LOCAL_TZ, DRW_OPEN_SUB_WINDOW, DRW_SETPOS, DRW_XPOS, and DRW_YPOS.
· The bas7.sd7 (basic interpreter) example program was improved.
· The functions drwPointerXpos, drwPointerYpos, drwHeight, and drwWidth in the file drw_win.c were improved.
· The functions closedir and wclosedir in dir_win.c were improved to call FindClose.
