+1, definitely!
If it is possible, the dateFormat method should also accept an optional
Locale parameter (as mentioned in TODO comment in the source), with a
default value of Locale.US.
Cheers,

Groovy Json users,
I recently worked on a project where it would have been helpful if
JsonOutput/JsonBuilder/StreamingJsonBuilder had options for
controlling the output. I noticed there were some open tickets [1]
for feature requests around this so decided to try to add some options
to control the serialization and have proposed a pull request
(https://github.com/apache/groovy/pull/371).
Just wanted to poll those that use the Json generating features in
Groovy to see if you think these options would be useful and would
welcome any code review for those that would be interested in
reviewing the PR. For a quick overview I've included a sample below [2].
[1]
GROOVY-6699: JSON slurper ability to ignore propertie/field names (at
least the serializing part)
GROOVY-6854: JsonOutput should be configurable with ISO 8601 UTC time
zone instead of GMT
GROOVY-7682: JsonBuilder or JsonOutput incompatible with JodaTime (for
now via a closure converter)
GROOVY-7780: JSONBuilder/JSONSlurper: Option to Only Include NonNull
values
GROOVY-7858: Make JsonBuilder configurable to not write entries with
null values
[2]
import groovy.json.*
def options = JsonOutput.options()
.excludeNulls()
.excludeFieldsByName('make','country','record')
.excludeFieldsByType(Number)
.addConverter(URL) { url ->'"http://groovy-lang.org";' }
StringWriter writer =new StringWriter()
StreamingJsonBuilder builder =new StreamingJsonBuilder(writer, options)
builder.records {
car {
name'HSV Maloo' make'Holden' year2006 country'Australia' homepagenew
URL('http://example.org')
record {
type'speed' description'production pickup truck with speed of
271kph' }
}
}
assert writer.toString() =='{"records":{"car":{"name":"HSV
Maloo","homepage":"http://groovy-lang.org"}}}'
