Is it possible to split script block into several parts?

[lishengting]

Just like

process multi_script_block {
   script:
   """
   #block1
   """
   if (params.a) {
      """
      #block2
      """
   }else{
      """
      #block3
      """
   }
   """
   #block4
   """
}

Is this possible?

Thanks!

Yes, all you need to do is return a string at the end. In this case, you can build up the string piece by piece:

process multi_script_block {
   script:
   def cmd = """
   #block1
   """
   if (params.a) {
      cmd += """
      #block2
      """
   }else{
      cmd += """
      #block3
      """
   }
   cmd += """
   #block4
   """
   return cmd
}
