Possible typo in documentation for mutate2

[Gavin-Holt]

Hi

The documentation for mutuate2 includes an example with named fields:

$ cat testdata/names.csv  \
    | csvtk mutate2 -n full_name -e ' $first_name + " " + $last_name '

Do these named fields need curly brackets?

$ cat testdata/names.csv  \
    | csvtk mutate2 -n full_name -e ' ${first_name} + " " + ${last_name} '

Kind Regards Gavin Holt

Thank you.

There's no need. Both works since csvtk v0.25.0.
