Paul King commented on GROOVY-9925:
-----------------------------------
We can no doubt improve those examples. All string forms are supported but will
require the appropriate escaping of backslashes or dollars as required, e.g.:
{code}
assert ' ' ==~ "^\\s+\$"
assert ' ' ==~ '^\\s+$'
{code}
> Groovy match operator documentation should contain real examples and slashy
> strings reminder

> Key: GROOVY-9925
> URL: https://issues.apache.org/jira/browse/GROOVY-9925
> Project: Groovy
> Issue Type: Documentation
> Affects Versions: 3.0.7
> Reporter: Alex Fredrickson
> Priority: Minor
>
> The [3.0.7 Groovy
> documentation|[https://docs.groovy-lang.org/latest/html/documentation/#_match_operator]]
> could be more clear on regex usage with match operators, particularly:
> # It would be helpful to note here that slashy strings are *required* for
> the match operator to work. `foo ==~ "^\s+$"` will never work. I know
> there's a section dedicated to slashy strings; it would be helpful to have a
> footnote here.
> # This section could benefit from a better example than `{{m = text ==~
> /match/}}`.
