Jan 5, 2016 · The following code examples all produce the same results where x evaluates to true according to Groovy Truth // These three code snippets mean the same thing. // If x is true according to groovy truth return x else return y x ?: y x ? x : y // Standard ternary operator.

In Groovy you also have to be aware that in addition to ==~, alias "Match operator", there is also =~, alias "Find Operator" and ~, alias "Pattern operator". All are explained here. ==~ result type: Boolean/boolean (there are no primitives in Groovy, all is not what it seems!) =~ result type: java.util.regex.Matcher ~ result type: java.util ...

Sep 20, 2018 · Add Groovy bin to PATH variable. Just add the bin folder of the unzipped Groovy pack to the environment variable PATH. Install the Code Runner extension for Visual Studio Code. This extension can be downloaded from the VS marketplace. If this is done, then you can at least run the groovy script already.

In groovy, the bitwise operators can be overridden with the leftShift (<<) and rightShift (>>) methods defined on the class. It's idiomatic groovy to use the leftShift method for append actions on strings, buffers, streams, arrays, etc and thats what you're seeing here.

The following works for me in Gradle / Groovy for build.gradle for an Android project, without having to import groovy.io.FileType (NOTE: Does not recurse subdirectories, but when I found this solution I no longer cared about recursion, so you may not either):

Aug 14, 2017 · In a GString (groovy string), any valid Groovy expression can be enclosed in the ${...} including method calls etc. This is detailed in the following page . Share

"this" in a block mean in Groovy always (be it a normal Java-like block or a Closure) the surrounding class (instance). "owner" is a property of the Closure and points to the embedding object, which is either a class (instance), and then then same as "this", or another Closure. I would forget about the scope thing totally for this part.

Jan 25, 2014 · .equals() does not behave the same in Groovy as it does in Java. Example here-- scroll down to 'GString and String'. Basically both items have to be of the same type of String class. Since the String class is implicit in the assignment -- GString is a Groovy language construct and String is an inline definition, something like def foo = "foo"...

Feb 16, 2012 · In Groovy you must always provide the class of an object being created, so there is no equivalent in Groovy to JavaScript's object-literal syntax. However, Groovy does have a literal syntax for a Map, which is conceptually very similar to a JavaScript object, i.e. both are a collection of properties or name-value pairs.

I want to use the following string literal inside my groovy program without having to escape the backslashes: C:\dev\username. Here is what I have tried so far: String (Single Quotes) & GStrings (Double Quotes) def aString = 'C:\dev\username' def aGString = "C:\dev\username"
