Description:
There are many times I find myself having to cast variables directly inside an
{{instanceof Class}} check.
In addition, I have found a specific problem with a generic {{}} where a method in the class that returns {{T}}, Groovy believes a
collection is being returned. This is the line in question:

The goal of this issue is to have the following codebase compile without
changes.

Paul King edited comment on GROOVY-8258 at 7/17/17 5:54 AM:
LINQ works across collections, XML documents (when parsing) and relational
databases using a stream-like API underneath. I'd be keen for us to work on
stream-based versions of SQL, XML and collection processing capabilities and
then think about the DSL sugar on top of that at a later stage. If it was
indeed a syntactic sugar layer on top of a well thought out API (as in C#) then
I think it would belong in the language.

[GitHub] groovy pull request #575: cache GroovyRunnerRegistry values
GitHub user jwagenleitner opened a pull request: https://github.com/apache/groovy/pull/575 cache GroovyRunnerRegistry values The registry should be read heavy and most use made of the iterator. Few writes/loads should occur, so values should be cached in order to optimize iteration. Benchmarked the change against using a read lock but `volatile` was significantly faster. You can merge this pull request into a Git repository by running: $ git pull https://github.com/jwagenleitner/groovy runner-values Alternatively you can review and apply these changes as the patch at: https://github.com/apache/groovy/pull/575.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #575 commit 28576c8da816a970d3a1151744f6b073f374e9a4 Author: John Wagenleitner Date: 2017-07-15T14:00:29Z cache GroovyRunnerRegistry values The registry should be read heavy and most use made of the iterator.

The DSL looks like it could be useful in certain situations. But my opinion is
that something like this would be best provided as an external library and not
included (from the start anyway) as part of Groovy itself or one of its
subprojects.

Just noting here that GROOVY-8251 is proposing that the method be renamed to
{{withCloseable}} to be consistent with the existing
{{withCloseable(java.io.Closeable...)}} method that exists in
{{IOGroovyMethods}}. See [PR 572|https://github.com/apache/groovy/pull/572].

[jira] [Created] (GROOVY-8259) add suppressed exceptions for with[Auto]Closeable methods
John Wagenleitner created GROOVY-8259:
-
Summary: add suppressed exceptions for with[Auto]Closeable methods
Key: GROOVY-8259
URL: https://issues.apache.org/jira/browse/GROOVY-8259
Project: Groovy
Issue Type: Improvement
Components: groovy-runtime
Affects Versions: 2.5.0-beta-1
Reporter: John Wagenleitner
Assignee: John Wagenleitner
Priority: Minor
As with the try-with-resources statement, if multiple exceptions are thrown the
exception from the closure should be returned and the exception from closing
should be added as a suppressed exception.
Currently the withCloseable/withAutoCloseable method return the closure
exception and log a warning if an exception is thrown on the call to
{{close()}}. With this improvement the exception from {{close()}} would also
be added as a suppressed exception to the exception thrown from the closure.
