Exporting __DATE__ and __TIME__
PostPosted: Tue Aug 11, 2015 9:39 am     Reply with quote

I am currently exporting the HEX file with the date compiled in the filename. The problem that I currently face is that I need to define the date manually. If I attempt to define the date as:

#define DATE __DATE__

it throws the quotation marks into the mix and Windows hates quotation marks in filenames.

So here is my current operational code:
Code:
#define DATE   11_AUG_2015

#define EXPNAME(a,b,c) a ##b ##c

#export (HEX, FILE = EXPNAME(MY_FILENAME_,DATE,.hex))


What I would like to use is the following:
Code:
#define DATE   __DATE__

#define EXPNAME(a,b,c) a ##b ##c

#export (HEX, FILE = EXPNAME(MY_FILENAME_,DATE,.hex))


Is there a way to remove the quotation marks from the date using the macro #define or any other method so that I can put the date automatically into the filename?

I'd say 'no'. Hopefully somebody will prove me wrong now!...

The value returned by __DATE__, is a string. Hence easy to use in things like printf. Now a macro argument can be converted to a string (# does this), hence it is sometimes referred to as the 'stringifying' operator. You'd need a 'de-stringifying' operator, but I don't think one exists.

Thanks for the info. I can't say that I was very positive in finding a solution as I didn't expect a solution to be available. My cohort and I were trying to find a method but we became stumped. But if anyone else can think of something, it would be welcome and appreciated.

What I do is stick to a numeric version:
Filename_YYYYMMDD.hex

I know it isn't exactly what you want but I like how it sorts alphabetically.
