------------------------------
> Slightly expanded error messages

>
> Key: GROOVY-11690
> URL: https://issues.apache.org/jira/browse/GROOVY-11690
> Project: Groovy
> Issue Type: Improvement
> Reporter: Paul King
> Assignee: Paul King
> Priority: Major
> Fix For: 5.0.0-beta-2
>
>
> Consider the following script (with intentional errors since we can't
> multiply strings):
> {code:groovy}
> @TypeChecked
> def method() {
> def alphabet = 'abcdefghijklmnopqrstuvwxyz0123456789'
> def alphabet2 = 'abcdefghijklmnopqrstuvwxyz0123456789' *
> 'abcdefghijklmnopqrstuvwxyz'
> def alphabet3 = 'abcdefghijklmnopqrstuvwxyz0123456789' + '' *
> 'abcdefghijklmnopqrstuvwxyz'
> }
> {code}
> When reporting on the first error we don't truncate at all:
> {noformat}
> [Static type checking] - Cannot find matching method
> java.lang.String#multiply(java.lang.String). Please check...
> @ line 4, column 21.
> def alphabet2 = 'abcdefghijklmnopqrstuvwxyz0123456789' *
> 'abcdefghijklmnopqrstuvwxyz'
> ^
> {noformat}
> For the second, since the error position is above position 40, we shrink the
> output taking 30 chars before and (up to) 10 after the position where the
> error occurs. It becomes quite minimal context and seems a quite drastic
> truncation given we don't care how long the above non-truncated string may be:
> {noformat}
> [Static type checking] - Cannot find matching method
> java.lang.String#multiply(java.lang.String). Please check...
> @ line 5, column 62.
> klmnopqrstuvwxyz0123456789' + '' * 'abcd
> ^
> {noformat}
> This kind of truncation was possibly justified when we were thinking of 80 x
> 24 terminals as our lowest common denominator for screen real estate, but
> seems a little excessive these days.
> Instead of 40, 30 and 10, I propose we use 60, 45 and 25, a very modest
> increase. This then gives a little more context:
> {noformat}
> [Static type checking] - Cannot find matching method
> java.lang.String#multiply(java.lang.String). Please check...
> @ line 5, column 62.
> 3 = 'abcdefghijklmnopqrstuvwxyz0123456789' + '' * 'abcdefghijklmnopqrs
> ^
> {noformat}
> I am open to further discussion about what the correct numbers should be but
> the above suggestion seemed to be a "no-brainer" as a little improvement.
