Hi David,
OK, so we're normally after columnar output. How about `-columns
C', where the string is output, as measured by wcwidth(), until
either the string ends or C would be exceeded.
How about -outsize, to be consistent with fmttest(1):
The -outsize switch controls the maximum number of printable
characters that the format engine will produce. Characters marked
as non-printing by the format engine with `%(zputlit)', characters
with zero width, and extra bytes that are part of a multibyte
character are not counted against this total. Two special values
are supported: “max”, which will set the value to the size of the
output buffer, and “width”, which will set the value to the width
of the terminal.
I know there are few nmh programmers that haven't coded assember, but
-outsize is something only a programmer could like. :-)
The functionality sounds OK, though it needs to know `Ｆoo' is 2+1+1;
there's no mention of wider-than-one runes above AFAICS. Also, is
`width' the value of `tput cols' this time, or one less again?
Then pad with ASCII space until C is met.
I don't think that we should add trailing space. The output need not
be columnar.
No, you're right. I was confusing it with `%42(decode{subject})'.
Cheers, Ralph.
