15:53 <orivej> Is there a function to print a systemtap aggregate variable in the same format it would be printed if I never read from it (@count=... @min=... @max=... @sum=... @avg=...)?

15:58 <fche> orivej, not a single function - just printf("") I guess, or if an array, a foreach/printf combo

15:59 <fche> we could grow a macro in the tapset that replicates the built-in auto-printer

15:59 <orivej> ok, thanks

16:00 <fche> if you'd like to try the tapset route, @define prints(s) %( printf("@count=%d @min=%d @max=%d ...", @count(%s), ... ) %)

16:00 <fche> kind of thing

16:00 <fche> %s -> @s actually at the end there

16:05 ravi_ has quit [Remote host closed the connection]

16:06 ego has quit [Ping timeout: 276 seconds]

16:07 <orivej> yes, this works:

16:07 <orivej> @define prints(s) %(

16:07 <orivej> printf("@count=%d @min=%d @max=%d @sum=%d @avg=%d\n",

16:07 <orivej> @count(@s), @min(@s), @max(@s), @sum(@s), @avg(@s))

16:07 <orivej> %)

16:08 <fche> neato. would you like us to include it in the distro for future versions ?

16:08 <orivej> i'm not experienced enough to decide

16:09 <fche> no problem, it looks good to me fwiw. do you mind if I put it into the repo under your name?

16:09 <orivej> ok

16:15 <fche> orivej, what email address shall we record for you?

16:15 <fche> (if you would like to share one)

16:16 <orivej> orivej@gmx.fr

16:16 <fche> ok

16:18 hchiramm has quit [Ping timeout: 276 seconds]

16:22 <orivej> fche, I submitted the issue about dash on Gentoo https://sourceware.org/bugzilla/show_bug.cgi?id=19700 , I can provide details here if you need any

16:24 <fche> ah right

16:24 <fche> that's on my queue shortly too

16:25 <fche> that last patch > $@ is cute

16:26 <orivej> I did not think of it until I saw ">> $@" in the generated Makefile

16:26 <fche> thanks for checking on the other uses of echo -n

17:28 <orivej> In fact I was surprised that "print" would not print a statistic variable, since it is documented to "print one or more values of any type". Would it be good to extend the family of print functions to support complex types?
