Contains the Ada 95 sources, on-line documentation in HTML format and the sources of some test programs. Includes a Makefile.

Last update of the Util library: Dec 01, 2002; Library version 1.1.

Description

The Util subsystem contains:

Time and Calendar handling not limited to the narrow range of the standard package Ada.Calendar. Both Julian and Gregorian calendars as well as a "universal" calendar using both are implemented.

Version 1.0 of the library also includes simple calendar additions such as UTC time operations, Image operations for Ada.Calendar.Time or a Day_Of_Week operation.
Access to the system environment including parsers for symbolic environment variable replacement.
Directory path manipulation operations. (V1.0 supports Windows and Unix style path syntaxes.)
A thick binding to the popen and pclose routines of C (works at least on Win NT/2k and Linux).
Some useful string operations, such as wildcard matching or finding strings (sequences delimited by a certain character such as ") within Ada strings, with optional handling of embedded string delimiter characters.
A simple generic reflection package giving the name of the construct where the instantiation occurs.
Some useful operations simplifying text file handling, such as a Get_Line that always returns a full line from the file, or a similar operation that also can skip blank lines and comments and even handle line continuations (like e.g. the "\" in Unix shell scripts or the "-" in DCL scripts).
A replacement for Ada.Strings.Unbounded with additional operations for slices of unbounded strings. (Util.Text)
And then some more...
