[jira] [Created] (GROOVY-7625) Slashy string in groovy allows brackets but double quoted string does not. Why?
Aseem Bansal created GROOVY-7625:
Summary: Slashy string in groovy allows brackets but double quoted
string does not. Why?
Key: GROOVY-7625
URL: https://issues.apache.org/jira/browse/GROOVY-7625
Project: Groovy
Issue Type: Documentation
Reporter: Aseem Bansal
Priority: Minor
This
println("$()")
gives me a compiler error "Either escape a dollar sign or bracket the value
expression"
But this
println(/$()/)
prints `$()` fine. No errors
Why is there a difference? The only documented difference is that slashy
strings make working with backslashes easier. I understand that a variable name
cannot start with a bracket so it should be possible to make that special case.
Is that the case for the slashy strings?
Just came across this when doing something with regex.

Did you fix the docs? Because I remember that there is another place where that
is written. Don't remember exactly where.

I mean there is an image present but the flow is wrong. It has a block "Method exists in MetaClass or Class" two times. One after GroovyInterceptable and other after the first "Method exists in MetaClass or Class" .

It is invoked when methodMissing is not present. This statement is as per the diagram. Also as per the answer at this is not an appropriate example http://stackoverflow.com/questions/19220370/what-is-the-difference-between-invokemethod-and-methodmissing Saying this because the answer by blackdrag (who I understand is a core committer to groovy) says that methodMissing should be used instead. Also the same page mentions "overhead of invokeMethod". It would be nic e to have a better explanation in the section of invokeMethod itself. I am not knowledgeable about this so cannot suggest what can be added. But it would be better to have the explanation in the official docs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

Issue Type: Bug
Reporter: Aseem Bansal
I was reading the docs when I came across "Note that the left shift operator is
used to append a new method. If the method already exists an exception will be
thrown."
I decided to try it via the below program. There was no exception. I am using
groovy 2.3.8
{noformat}
class A {
}
A.metaClass.hello = {
"hello superclass"
}
class B extends A {
}
B.metaClass.hello << {
"hello subclass"
}
B.metaClass.hello << {
"hello subclass"
}
new B().hello()
