Subject [jira] [Reopened] (GROOVY-7935) Right side of assignment - remove parens or not?
Date Sun, 25 Sep 2016 21:29:20 GMT


tinne reopened GROOVY-7935:

Thank you for the rapid documentation update. I am however afraid that "{{def m = bar}} won't
work" may be a bit brief explanation, as indeed, the assignment does work, but not as one
might possibly expect: it defines {{m}} as an alternative variable to denote the closure the
name {{bar}} is currenly assigned to.

This is not explained in either the style guide or the semantics document.

>                 URL:
>             Project: Groovy
>          Issue Type: Bug
>          Components: Documentation
>         Environment:, release 2.4.7
>            Reporter: tinne
>            Assignee: John Wagenleitner
>            Priority: Minor
>             Fix For: 2.4.8
> The Groovy [style guide|] says, "...  Groovy doesn’t
allow you to remove parentheses. [...] for nested method calls or on the right-hand side of
an assignment, you can’t omit them there."
> Then, a code fragment is given, where just this works.
> {noformat}
> def foo(n) { n }
> println foo 1 // won't work, as documented
> def m = foo 1 // this works indeed!
> {noformat}
> Further more, I could not find any examples, where this would not work, neither with
comma separated parameter lists nor with infix computations nor closures.
> So I guess it is just a documentation bug and right-hand side parens removal support
has been added.
