These function operate on or generate slices of strings. In Go, a slice is a
growable array. In Sprig, it's a special case of a list.
Join a list of strings into a single string, with the given separator.
list "hello" "world" | join "_"
The above will produce hello_world
join will try to convert non-strings to a string value:
list 1 2 3 | join "+"
The above will produce 1+2+3
Split a string into a list of strings:
splitList "$" "foo$bar$baz"
The above will return [foo bar baz]
The older split function splits a string into a dict. It is designed to make
it easy to use template dot notation for accessing members:
$a := split "$" "foo$bar$baz"
The above produces a map with index keys. {_0: foo, _1: bar, _2: baz}
$a._0
The above produces foo
splitn function splits a string into a dict. It is designed to make
it easy to use template dot notation for accessing members:
$a := splitn "$" 2 "foo$bar$baz"
The above produces a map with index keys. {_0: foo, _1: bar$baz}
$a._0
The above produces foo
The sortAlpha function sorts a list of strings into alphabetical (lexicographical)
order.
It does not sort in place, but returns a sorted copy of the list, in keeping with the immutability of lists.
