Can anyone explain why lines 1a and 2a do not print out the entire range but lines 1b, 1c, 2b and 2c do?
Script
println GroovySystem.version
def range = 1..5
printf "1a: range %s %n", range
printf "1b: range %s %n", range.toString()
printf "1c: range %s %n", range, ""
printf "2a: range %s %n", range.asList()
printf "2b: range %s %n", range.asList().toString()
printf "2c: range %s %n", range.asList(), ""
Output
3.0.9
1a: range 1
1b: range 1..5
1c: range 1..5
2a: range 1
2b: range 1..5
2c: range 1..5
I am new to groovy but I would expect 1a and 1c to be the same (likewise for 2a and 2c).
def range = 1..5
printf "1a: range %s %n", range
printf "1b: range %s %n", 1,2,3,4,5 //same as 1a
printf "1c: range %s %n", *range, "" //same as 1,2,3,4,5,""
printf "2a: range %s %n", range, ""
printf "2b: range %s %n", [range, ""] //same as 2a
printf "2c: range %s %n", [range]
result
1a: range 1
1b: range 1
1c: range 1
2a: range 1..5
2b: range 1..5
2c: range 1..5
all parameters to printf passed as a list.
so, if you passing just one parameter that is a list then every element of list considered as a separate parameter.
it means that 1a and 1b are equivalent
that's why all 1* examples giving just a first element of a list (range)
2c shows a workaround for this
