hi, forks...

see this source

irb(main):015:0> puts "%*s" % [ "1", 2 ]
TypeError: can't convert String into Integer
from (irb):15:in `%'
from (irb):15
from :0
irb(main):016:0>

AIK, "%*s" is to use for concatenation of array.

but, I met the previous error message.

What's different ways I can take?

can you point me a link to that info?


afaik, "*" is used for field widths, eg,

> p "%*s" % [2,"1"]
" 1"

> p "%*s" % [2,1]
" 1"

> p "%.*s" % [2,"abcdef"]
"ab"

From: Pe=F1a, Botp [private.php?do=newpm&u=]=20
#
# afaik, "*" is used for field widths, eg,

or precisions

#=20
# > p "%*s" % [2,"1"]
# " 1"
#=20
# > p "%*s" % [2,1]
# " 1"
#=20
# > p "%.*s" % [2,"abcdef"]
# "ab"
#=20

also, if just plain concat, %s will do

> puts "%s" % [["1", 2]]

Maybe you meant "%*s" % [ 2, "1" ] if you expect " 1".
