Nextflow scripting¶ The Nextflow scripting language is an extension of the Groovy programming language. Dynamic typing means that unlike in Java and other statically-type languages where a variable has a specific type such as String and only takes values of that type, Groovy allows you to change the type as well as value of the variable simply by assigning it a value or object reference of a different type. This example will show how to convert a string to a double or float in groovy. In the Groovy programming language it is possible to define variables in a typed or untyped fashion. You write Groovy scripts using Application Composer's expression builder, which appears in many places as you modify existing objects or create new custom ones. The Nextflow syntax has been specialized to ease the writing of computational pipelines in a declarative manner. A nested anonymous code block defines another scope as in the following Groovy script that declares two variables called "a", each in a different block. String normal = "Good in java" normal = 1 //very bad--statically typed def groovy = "groovy" groovy = 1 // in a variable of dynamic type (Object-esce) Since Groovy is a scripting language, it's important to note that it handles variables like a script does as well.
