Seed7

The chapter explaining 'operating system access' in the manual was improved. The standard path representation was changed to forbid drive letters. The spacing between characters in the standard bitmap fonts was improved. The functions toStdPath and convDosPath were improved. The interpreter and compiler were improved to support for-until loops for the type 'ref_list'. The initialization of hash and string constants in the compiler was improved. The implementation of the function path(PROGRAM) in the interpreter was improved. The drawing functions for filled areas were improved in "drw_x11.c".

The function convDosPath was added to the "seed7_05.s7i" library. It converts a path with backslashes and drive letters to the standard path representation. Functions with path parameters or path result were improved to accept and return file paths with the standard path representation. The functions path(PROGRAM) and dir(PROGRAM) were added to the "seed7_05.s7i" library. The function path(PROGRAM) returns the absolute path of the program. The function dir(PROGRAM) returns the directory containing the program. The function getenv was improved to work with Unicode environment variables.

The handling of closures in the compiler ("comp.sd7") was improved. The compiler uses code inlining or C functions to implement closures. A new example program (make7.sd7), a make utility that can be used to manage the compilation process, was added. The "tar.s7i" library, which allows programs to deal with tar files without the need to call external programs, was added. The directory seed7/bin was introduced as a place for executables and runtime libraries. The performance of the str function (conversion to string), for integer and bigInteger values, was improved.

The interpreter and compiler were improved to support Unicode program arguments under Windows. The 'carddemo.sd7' program was improved to allow moving, raising, and lowering cards. The chapter explaining the file open function in the manual was improved. Bitmap fonts were improved to allow scaling. The handling of Expose events in the "drw_x11.c" driver was improved. The function 'getHttp' in "gethttp.s7i" was improved to handle several status codes. The file open function was improved to return STD_NULL on an attempt to open a directory. The makefiles were improved to use a generic "chkccomp.c".

The chapters explaining integer and bigInteger in the manual were improved. Several improvements were made in the "gzip.s7i" library. The tar archiving program (tar7.sd7) was improved. The compiler was improved to generate better code for the power operator. The compiler and the runtime library were improved to use string slices instead of copying, when possible. The compiler and the runtime library were improved to allow appending an element to an array with the &:= operator. String and array indexing functions in the compiler were improved. The file "read_me" was renamed to "read_me.txt".
