Hi,
I'm curious about how you are using string. I think string are quite
useful, but how they are fixed size, I'm often defining them in the
declare part.
I don't know if it's a good practice, but I got code like this:
urio: constant AWS.URL.Object := AWS.Status.URI(request);
host_raw: constant String := AWS.Status.Host(request);
host: constant String := host_raw(host_raw'First ..
First_Index(host_raw, ':'));
www: constant String := SCMAL.Httpd.Servers.GetWWW(host);
Filename: constant String := AWS.URL.Abs_Path(urio);
and so on.
So the main problem is error management. If one function raise
exception, the exception can't be catch except with the following trick:
procedure Patati_Patata is
begin
declare
s: String := A_Function_Raising_Constraint_Error;
begin
-- some code
null;
end;
exception
when Constraint_Error =>
Put_Line("I got an error");
end;
Is there nicer way to do that? I'm trying to avoid Unbounded_String
because of the conversion when mixing Unbounded_String and String.
