Possibility of output object with named values?

[xsvato01]

Hi, I was wondering if it is possible in Nextflow to ouput named object from processes. For example:

process Foo {
	output:
	tuple path("file.txt"), ['word': env(SAY), 'something_else': val(8)]

	script:
	"""
        touch file.txt
	SAY=\$(echo whatever)
 	"""
}

This will not work, but something similar can be achieved with

process Foo {
	output:
	tuple path("file.txt"), env(SAY),  val(8)

	script:
	"""
        touch file.txt
	SAY=\$(echo whatever)
 	"""
}

workflow {
	Foo()
	.map{ it -> [ it[0], [word: it[1], something_else: it[2] ] }
	.view()
}

Perhaps there is any more elegant way without needing to map over the individual outputs...?

For now your example is the best you can do. Named outputs (record types) are on the roadmap, but there are a few moving pieces involved so I'm not yet sure when it will be ready

Lovely, thanks for the heads-up!
