Groovy GStrings and numberformat -


i'm writing script in groovy process files , have following method create resulting filename

static string formatfilename(string prefix, int counter, string extension) {     string counters = string.format('%04d', counter)     return "$prefix-$counters$extension" }

is there more elegant way of formatting counter in gstring?

frankly, there's not can here. making shorter nitpicking.

as mentioned in tim_yates' comment, make one-liner

return "$prefix-${string.format('%04d', counter)}$extension"

i can think of 1 way make shorter, give on gstrings , use sprintf instead, example of groovy goodness. namely, extension method of object class. personally, find easier read braces mashup.

return sprintf("%s-%04d%s", prefix, counter, extension)
