I am pretty sure that an horizontal iterator was recently implemented for the
format
used within mprintf(), but i am failing to find any information about how to
use it.
What do you mean by "horizontal iterator" ? Is it like the "argument_index$"
for Java [1] ?
I don't know much java, but as Fortran format allows it with "#(...)",
this one replicates at most #times the content of ()
(that may have other (...) patterns (recursive
replication/substitution))... Then, for all provided data, the format is
feed with
row-wise input data and builds the output with replicating the format as
many times as some input data remain
(for the current row), and then stop without error (even before the end
of the format).
Unfortunately, write() that could manage such a handy fortran format is
not well implemented:
* the write() format cannot mix input data types (bug 3798)
<http://bugzilla.scilab.org/3798>
* when the write() format meets a string (a), its parsing stops (bug
12476) <http://bugzilla.scilab.org/12476>
Being so handicaped, write() has not much interest wrt mprintf(), and
AFAIK, there is presently
no native Scilab function handling input data in this way. We are
compelled to use things
like this msprintf():
--> NL=4; NC=6; Nchar=5;
--> data =
matrix(strsplit(ascii(grand(NL*NC*Nchar,1,"uin",32,126)),(1:NL*NC-1)*Nchar),NL,NC)
data =
!/6QV0 L)3zw I<wxX l/u02 f(kAd #P8oI !
! !
!+`kUF !'{*` BE$d% q3WnC Ch:iP 3|fj^ !
! !
!FdBRS !Gsp" VkE<- ySYC< UNX-. Gbfb# !
! !
!xJZH3 W!(g" ~p9@z 3Df9 6CjU7 MDWnB !
--> mprintf(strcat(emptystr(1,size(data,2))+"%10s ")+"\n", data)
/6QV0 L)3zw I<wxX l/u02 f(kAd #P8oI
+`kUF !'{*` BE$d% q3WnC Ch:iP 3|fj^
FdBRS !Gsp" VkE<- ySYC< UNX-. Gbfb#
xJZH3 W!(g" ~p9@z 3Df9 6CjU7 MDWnB
since write() misworks:
--> write(%io(2), data, "((2x a))")
