Brian Ray created GROOVY-8026:
---------------------------------
Summary: Matcher indexed via IntRange with startIdx..-1 does not
return "intermediate" range matches
Key: GROOVY-8026
URL: https://issues.apache.org/jira/browse/GROOVY-8026
Project: Groovy
Issue Type: Bug
Components: groovy-jdk
Affects Versions: 2.4.7
Environment: Zulu OpenJDK 1.8.0_102-b14
Windows 7 Pro
Reporter: Brian Ray
Priority: Minor
Maybe this isn't a bug, and I realize that a {{Matcher}} is not exactly a
{{List}} or any other {{Collection}}, but the inconsistency is a little
mysterious. Here's a simple Groovysh script with several comparative indexes:
{code:java}
txt = 'abcd 1 efgh 2 ijkl 3 mnop'
m = txt =~ /\d/
println m.collect { it } // as expected: [1, 2, 3]
println m[ 0..2 ] // as expected: [1, 2, 3]
println m[ 0..m.size()-1 ] // as expected: [1, 2, 3]
println m[ 0..<m.size() ] // as expected: [1, 2, 3]
println m[ 0..-1 ] // bug?: [1, 3]
//for comparison
a = [ 1, 2, 3 ]
println a.collect { it } // [1, 2, 3]
println a[ 0..2 ] // [1, 2, 3]
println a[ 0..a.size()-1 ] // [1, 2, 3]
println a[ 0..<a.size() ] // [1, 2, 3]
println a[ 0..-1 ] // [1, 2, 3]
{code}
