[Question] How to inject combination of variables in flag?

[OopsYao]

The doc describes how to use variable injection like ${--flag:key}, but how do I inject something like --lines 5-9 containing 2-more variables as a combination, where 5 is rowStart while 9 is rowEnd?

You can write your own shell script wrapper that can accept row start and row end and then pass it to the command you want to call

Oh yes, didn't realize it. And I guess we can use something like xargs if we don't want a standalone wrapper.

Here is an example of latexindent with range formatting if any one is interested:

latexindent $(echo ${--useless:rowStart} ${--useless:rowEnd} | xargs -n4 -r sh -c 'echo --lines $(($1+1))-$(($3+1))')
