Passing an array of Strings from Groovy to Javascript

Question

I am building an array of Strings in my Groovy code and want to pass the array to a JavaScript script contained in my code. However, Groovy doesn't put the strings in the array into quotes as Javascript expects. I'm passing the array using GStrings:

var strains = ${strainNames};

JavaScript evaluates it to this:

var strains = [pseudomonas_aeruginosa_D421, pseudomonas_aeruginosa_OC2E, pseudomonas_aeruginosa_EA0A, pseudomonas_aeruginosa_0812];

Is there a way to add quotes to each element or do I already have to add them in my Groovy code?

You could change:

var strains = ${strainNames};

to

var strains = ${strainNames.inspect()};

That gives me the same array without quotes.

FWIW, for me, @tim_yates' answer works as expected (adding quotes to the array elements), using Groovy v3.0.11. From the .inspect docs, .inspect() returns a String that matches what would be typed into a terminal to create this object, e.g. [1, 'hello'].inspect() -> [1, 'hello']

You could try to include it as a string and transform it to an array:

var strains = "${strainNames}"
  .slice(1, -1)  // Remove brackets
  .split(", ");   // Split at separators
