Hi

I need a range of Dates.

So I tried this:

Begin_Date: Dates.Object; 
End_Date: Dates.Object;
-- Dates is a package from an earlier example in my Ada95 book. It is based on Ada.Calendars. I prefer to use
-- Dates because I actually need only the date, I don't care/ need the hour. I also find the name "Time" for 
-- something like "2015/10/31 21:00:00" confusing but that's just my opinion.

That doesn't work unfortunately and the compiler is right to complain:

subtype Period is range Begin_Date .. End_Date;

I naively thought that it could be so easy.

I could solve this problem with a few loops and filling an array or a list with the generated dates but the loop thing will be probably very ugly/complicated. 

For the array I also have to know how many dates I actually have between Begin_Date and End_Date. I have tried to 

I have found in Ada.Calendar a: function "-" (L,R:Time) return Duration

Is it possible to make a casting to convert my Date type in (Ada.Calendar) Time type:

Today : Ada.Calendar.Time:= Time(Date); -- or something like that.

I could of course use the Getters from Dates and then construct a new Time. More of curiosity than an actual problem.

Well of course I could simply use Ada.Calendar.

So is there an existing package which generates a range of Dates from .. to ?
Feels like cheating but causes less frustration. 

 Thanks

Laurent

PS: need this range of dates because the log files I want to read and extract informations from are all named like this: vba-yyyymmdd.log where obviously yyyymmdd is the date. The program generates a new file every date an stores the communication it treated in it.

I want to read this files and extract the messages which passed. Is more an exercise than actually a need to do it.
