I'm trying to right-pad a string up to 9 characters, for example "12345"
should become "12345 ", and the only idea I've come up with so far is to
use clojure.core/format which states: "Formats a string using
java.lang.String.format, see java.util.Formatter for format string syntax".
However,
there seems to be a discrepancy in what the Clojure format function returns
compared with the Java formatter.
In Java, new Formatter().format("'%-9s'", "12345") correctly returns '12345
' - the ' are there for legibility. String.format("'%-9s'", "12345")also
returns the correctly padded string.
However, in Clojure (format "'%-9s'" "12345") returns '12345 ' - it has
only padded the string by 1 space, and not 4 as with the Java version.
Also, (String/format "'%-9s'" (to-array "12345")) - taken from the
clojure.core/format source and substituting parameters directly- returns '1
', and (String/format "'%-9s'" (to-array '(\1 \2 \3 \4 \5))) returns '1
'.
The one thing that works correctly is (String/format "'%-9s'" (to-array
["12345"])) which returns '12345 '.
I'm not really clear on what's going wrong here, but clojure.core/format
doesn't appear to be working as described - at least for a single string
argument.
I'll continue to investigate, but if anyone can offer some comments to
help? ...
