feat: add awk formatter

[trevarj]

Add formatter for awk programs. Surprise! It's awk!

Hi guys,

I know this has been closed, but would it be possible to add an additional formatter for awk, likely being prettier-plugin-awk?

Two main reasons why I'm asking this.

1. Not everyone will be using gawk (gnu awk), other versions (like mawk) come installed as the default on a lot of systems such as Debian and Ubuntu, it would be nice for there to be an option for these systems without installing gawk
2. Gawk pretty printing (as you have here) uses profiling behind the scenes, the output of which can differ a lot from what you're trying to write.. Especially in the case where you're using @include to import functions from another awk file, which gawk pretty-print does not like at all. prettier-plugin-awk does a much better job of this. (I can provide examples if you like).

I hope this is considered as I believe that prettier-plugin-awk is a better formatter than using gawk's pretty-print feature. It's more universal across all awk versions and also does a better job in general.

Regards,
Joel

@Givo29 maybe you can just add a separate "awk-prettier" formatter. Seems better since people may not be using prettier and have this extension installed.

I have done that for now @trevarj, I just thought I'd also make the suggestion here.

You make a valid point though, not everyone will have prettier installed either.

What I've done:

formatters = {
    awk_prettier = {
        command = "~/.nvm/versions/node/v20.17.0/bin/prettier",
        args = { "--stdin-filepath", "$FILENAME" }
    }
},

The only unfortunate part is I have to globally install prettier and prettier-plugin-awk as it won't work using the mason installed prettier instance...
