> Follow-up of CAMEL-26465, named in its description.
> CAMEL-26465 keeps an empty argument in its place, and does not split at a
> comma inside a nested function, for the functions that use
> {{SimpleFunctionHelper.splitArguments}} ({{replace}}, {{substring}},
> {{substringBefore}}, {{substringAfter}}, {{substringBetween}}, {{contains}},
> the collection functions with arguments) and {{join}}. The other functions
> with arguments split their own way ({{StringQuoteHelper.splitSafeQuote}}, or
> {{String.split}}) and still have both problems: {{concat}}, {{pad}},
> {{convertTo}}, {{iif}}, {{hash}}, {{assert}}, {{throwException}},
> {{function(...)}}, {{range}}, {{random}} and the math functions {{sum}},
> {{max}}, {{min}}, {{average}}. An empty argument is dropped so the next one
> takes its place (for example {{$\{hash(,SHA3-256)\}}} hashes the text
> {{SHA3-256}}, {{$\{concat(,x)\}}} concats {{x}} with the body only by
> accident of the order), and a comma inside a nested function such as
> {{$\{header.s.substring(1,3)\}}} splits the argument, so
> {{$\{iif($\{header.foo\} > 0,$\{header.s.substring(1,3)\},no)\}}} and
> {{$\{random($\{header.min.substring(0,2)\},50)\}}} fail to parse.
> *Proposal*
> Split the arguments of these functions with the same rules
> ({{SimpleFunctionHelper.splitArgumentsAsWritten}}), with the same rule for an
> empty argument (the default where the function has one: the body for an
> expression the function otherwise reads from the body, 0 for the min of
> {{range}} and {{random}}, SHA-256 for the algorithm of {{hash}}, a space for
> the separator of {{pad}}, the default exception type; refused where it has
> none), tests per function, and an upgrade guide entry next to the one of
> CAMEL-26465. The values of {{sum}}, {{max}}, {{min}} and {{average}} are a
> list, where an empty value stays no value, as for {{list}} and {{map}}.
