[Question] What is the meaning of "it" inside "any" closure?

[Abu3safeer]

Hello, I read this viewtopic.php?t=12369
in the example

Code: Select all

{languages.any{ audioLanguages =~ it } ? "[Original Language]" : "[Dubbed]"}

What is the meaning of "it", also what does "=~" mean?

[rednoah]

it is the parameter that is passed as argument to the closure: Groovy Language Documentation › Implicit parameter

=~ is the regex-find operator: Groovy Language Documentation › Find operator



tl;dr this is short:

Groovy: Select all

languages.any{ audioLanguages =~ it }

for this:

Groovy: Select all

languages.any{ language -> java.util.regex.Pattern.compile(language.toString()).matcher(audioLanguages.toString()).find()  }
