How to detect new line from std_in?

How to detect new line from std_in?

[Centaury]

I'm writing a program that reads text from std_in whether by keyboard entry
or file redirection.
If I have something that looks like this;

harlooo and welcome to
the greatest circus

my program would only recognise that there is 6 words, instead of 7. This is
because to and the are joined together and become tothe as the data in my
linked list.

What is the keyword to detect new line (or is it something else??)

Please reply

Regards,

Centaury

If you are using Ada.Text_IO, there is no "keyword" for the end of line.
Text_IO is a line-oriented view of a file; you have to read the file
with Get_Line, and keep track of line breaks yourself.

If you are reading the file with Stream_IO, then you should see some
character(s) representing the line break, but this is operating system
(and editor!) dependent.

    It sounds like you are reading the input a byte at a time with the
    "Get" procedure and, given its semantics, it bypasses the end of
    line marker and starts at the next line of input. You should take
    a serious look at the package Ada.Text_IO. It might suggest easier
    ways to do this, such as reading in a whole line at a time and
    concatenating lines if you want to process the input as a
    character at a time.

    But, given that you want to look at it a character at a time, you
    will want to look up these functions in Ada.Text_IO: End_Of_Line,
    End_Of_Page and End_Of_File. If you're reading a character at a
    time, you probably need to look at all these functions to know
    when to stop.
