[Chicken-hackers] [PATCH] chicken-status: add -eggs command line option

[Mario Domenech Goulart]

Hi,

Currently, chicken-status lists information about extensions. As far as
I understand, eggs can contain one or more programs/extensions.  It
would be handy if chicken-status could list eggs only, so we could use
its output to feed chicken-install, for example.  It can be useful when
you update Chicken and want to install all eggs installed for the old
Chicken.

Example:

  $ <new-prefix>/bin/chicken-install `<old-prefix>/bin/chicken-status -eggs`

Attached is a patch to add a -eggs (or -e) command line option to
chicken-status.

It is possible (although not usual and probably not recommended) to make
eggs install multiple extensions with different versions.
chicken-install only stores versions of extensions in the local repo.
It does not store information about egg versions. Thus, this patch does
not address egg versions, since chicken-status is unable to determine
them.  It simply lists egg names.  Making it list names and versions
would be much better, but I don't know an easy way to do that (maybe
chicken-install should add an egg-version tag to .setup-info files? Or
maybe eggs that install different extension versions should be
considered broken?)

Best wishes.
Mario
