-----------------------------------
This appears fixed in the Parrot parser.
> CLONE - Enum constructor with value throws "unexpected token" error
> -------------------------------------------------------------------
>
> Key: GROOVY-7778
> URL: https://issues.apache.org/jira/browse/GROOVY-7778
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.4.6
> Environment: Windows 7 Professional
> JDK 1.8.0_45
> Reporter: Brian Ray
> Priority: Minor
>
> First time submitter to this JIRA so let me know if I've specified anything
> incorrectly. I just upgraded from 2.4.4 to 2.4.6 and now declaring an enum
> constructor accepting a value as follows:
> {code:title=UsStates.groovy}
> enum UsState {
>
> ID('Idaho'),
> IL('Illinois'),
> IN('Indiana'),
>
> UsState( String value ) { this.value = value }
> private final String value
>
> String toString() { return value }
> }
> println UsState.ID //Idaho
> {code}
> throws the following compile error:
> {code}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> C:\svn_qa\jenkins_trunk\scripts\UsStates.groovy: 7: unexpected token: this @
> line 7, column 29.
> UsState( String value ) { this.value = value }
> ^
> 1 error
> {code}
> No such error occurred in 2.4.4, nor does it happen in 2.4.5. Here are a few
> contrasting things that do seem to work in 2.4.6:
> {code:title=UsStatesBoring.groovy}
> enum UsState {
>
> ID,
> IL,
> IN,
> }
> println UsState.ID //ID
> {code}
> {code:title=UsStatesNoEnum.groovy}
> class UsState {
>
> UsState( String value ) { this.value = value }
> private final String value
>
> String toString() { return value }
> }
> final idaho = new UsState('Idaho')
> println idaho //Idaho
> {code}
> Though this seems higher priority than Minor, I can work around it by simply
> downgrading to 2.4.5. I wish there was a Medium priority.
