Date format in prompt

Bart et al -

I've used prompt bart for as long as I can remember.  But I'm an ISO date
kind of guy, and I'd like to use %D{%Y-%m-%d} to get a four-digit year.
I've grovelled through the source code, but I can't figure out how to make
the change.  Is there an easy way to do what I want?

Thanks,
  Vin

Nice to know somebody else does. :-)

It's this line in prompt_bart_ps1:

    date="%{$fg[%D]%}%D$rs"     # Prefer "%{$fg[%D]%}%W$rs" in the USA?

Just change to

    date="%{$fg[%D]%}%D{%Y-%m-%d}$rs"

If changing in real time in an interactive shell (e.g. with zed -f),
you then have to re-run prompt_bart_ps1

Excellent!  Thanks.  I copied prompt_bart_setup and changed the appropriate
line.

In the spirit of being greedy and improving the UX, how would you
parameterize this; how would you support US/normal/ISO date formats
(looking at the comment) in the same function?

Best,
  Vin

I suppose the right way would be to add additional zstyles within the
:prompt-theme context.  The command line for "prompt [name] ..." is
already overloaded in a way that is not easily extensible.
