do not ANSI color --version, especially if output is not interactive TTY

[yarikoptic]

since I might use it in filename but

and I end up with

$> bvv=$(bids-validator-deno --version | awk '{{print $2;}}'); mkdir derivatives/; bids-validator-deno --json -o derivatives/bids-validator-$bvv.json .

$> ls -l derivatives/
total 84

That's supposed to be detected automatically. You can force it with NO_COLOR=1.

Looks like we can use Deno.stdout.isTerminal() to make sure that colors are turned off.

󰅂 echo 'Deno.stdout.isTerminal()' | deno -q | cat
false
󰅂 echo 'Deno.stdout.isTerminal()' | deno -q      
true

It's silly but using the short form of the flag should produce what you're looking for.

$ ./local-run -V
2.1.1

Version flag is currently handled automatically by the library Cliffy.

ha, cool @rwblair , I will try to remember . Comes a little unexpected since no such difference is noted in

-V, --version                          - Show the version number for this program.
