[Question] Multiple arg pairs

[fxwiegand]

Hello,
I want to create a subcommand that would look somehow like this:
mytool subcommand my.vcf my.bam my_other.vcf another.bam ...
where the number of vcf/bam pairs are not limited. I struggle to find a way to parse these multiple alternating arguments without throwing my vcf and bam files together and making them one multiple arg. Thanks for your help!

Um, probably Arg::new("pairs").multiple(true).number_of_values(2)? Then you can iterate through the pairs using values_of("pairs")

This might do the trick thank you! Although I'd still have to name one argument something like vcf-bam-pair so I couldn't give a separate description for vcf and bam in the help section right?

Something like that

Thanks a lot!
