------------------------------------------
Summary: Parrot can't parse closure
Key: GROOVY-10152
URL: https://issues.apache.org/jira/browse/GROOVY-10152
Project: Groovy
Issue Type: Bug
Components: parser-antlr4
Affects Versions: 3.0.8
Reporter: Christopher Smith
I have this "cleanup" method in an ETL project. The intent is to call a static
method returning {{Try<String>}} that attempts to normalize a phone number,
then check whether we had an error processing any of them; if so, return a
failure, but if success, replace the existing phone numbers with the normalized
ones and return the record.
{code:groovy}
static Try<IdentityRecord> normalizePhones(IdentityRecord record) {
Map<String, Try<String>> normalized = record.phones.collectEntries {
ctx, number ->
[ctx, PhoneRules.normalize(number)]
}
return normalized.entrySet().stream()
.filter { it.value.failure }
.findFirst()
.map { Try.failure(new ValidationException("${it.key}:
${it.value.cause.message}")) }
.orElseGet {
record.phones = normalized.collectEntries { ctx, tr -> ctx,
tr.value }
Try.success(record)
}
}
{code}
Parrot is giving me a generic parse error on the closure for the {{orElseGet}}
call, and I can't figure out why. Commenting out the assignment statement
removes the error (but of course prevents the intended modification). Adding
{{_ ->}} does not change the error, and neither does inserting semicolons in
various places.
