Re: [fpc-pascal] {$include %dateyear%}
I can put some more thought into it.. but I'm wondering how to properly submit a change request for this documentation. James ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] {$include %dateyear%}
Well, Writeln('{$I %DATEMONTH%}'+'/'); can be compiled, but the answer is...
{$I %DATEMONTH%} .
I think that my level of english is by far too low to make the correct sentence.
Cheers, James, Raoul

I see what you mean... I thought it was an Integer because If you do something
like:
Writeln({$I %DATEMONTH%}+'/'+{$I %DATEDAY%}+'/'+{$I %DATEYEAR%});
You get Error: Operator is not overloaded: "ShortInt" + "Char"
But that's not what it is it's just like typing in hard coded numbers
after it's compiled.. because you can do things like
Writeln('{$I %DATEMONTH%}'+'/');
And you wouldn't be able to do that with variables or any type... so it's
really not any variable type, it's just numeric text being inserted.
I don't really know what to call it, but integer seems to indicate it has a
type, so I agree it should be distinguished from any specific variable type.

Re: [fpc-pascal] {$include %dateyear%}
Helolo James,
Thank you for your comment and proposal. As there is no type associated with non-string results, would it
be better to say number instead of integer ? Or integer number ?
Season's greetings !
Cheers, Ched'

I would agree that the documentation actually states quite clearly that they
are ALL strings except %linenum% and the documentation should be improved to be
accurate.
Perhaps
{$INCLUDE %XXX%}
the {$INCLUDE} directive inserts a string or integer constant in the source
code.
Here XXX can be one of the following:
CURRENTROUTINE
Inserts a string containing the name of the current routine. Useful for debug
logging.
DATE
Inserts a string containing the current date. It will be formatted as
/MM/DD.
DATEYEAR
Inserts an integer containing the year part of the current date.
DATEMONTH
Inserts an integer containing the month part of the current date.
DATEDAY
Inserts an integer containing the day part of the current date.
FPCTARGET
Inserts a string containing the target CPU name. (deprecated, use FPCTARGETCPU)
FPCTARGETCPU
Inserts a string containing the target CPU name.
FPCTARGETOS
Inserts a string containing the target OS name.
FPCVERSION
Inserts a string containing the current compiler version number.
FILE
Inserts a string containing the filename in which the directive is found.
LINE
Inserts a string containing the line number on which the directive is found.
LINENUM
Inserts an integer containing the line number on which the directive is found.
TIME
Inserts a string containing the current time, formatted as HH:MM:SS
TIMEHOUR
Inserts an integer containing the hour part of the current time.
TIMEMINUTE
Inserts an integer containing the minutes part of the current time.
TIMESECOND
Inserts an integer containing the seconds part of the current time.
If XXX is none of the above, then it is assumed to be the name of an
environment variable. Its value will be fetched as a string from the
environment when compiled, if it exists, otherwise an empty string is inserted.
(we don't need to mention the integer exceptions here because we are only
talking about environment variables now)
I didn't know these directives existed, so thanks for the Christmas present,
these will be very useful!
James

Subject: [fpc-pascal] {$include %dateyear%}
Hello All,
I'm reading https://www.freepascal.org/docs-html/prog/progsu41.html
It seems to me that {$include %dateyear%} , {$include %datemonthr%} and
{$include %dateday%} are treated as numbers in the source code, not a string
as expected from the description (only linenum is supposed to be a number).
I'm really happy with numbers, but I think that the description could be
improved , isn't it ?
Best wishes and season's greetings to all Freepascalists.
Cheers, Ched'
