Specifying & searching of package flavors

[parv/freebsd]

Hi there,

1- How does one search for available flavors of a package by partial
or full package origin?

For example, given origin of "devel/lua-stdlib" would install the packages
for all available versions of lua (5.1--5.4). Only way I found that that
would be the case is during the actual install.

Issues here ...
- "pkg search lua-stdlib" does not show any results;
- "pkg install lua-***@lua54" fails to find any available packages.
Only
thing that would work is "lua54-stdlib";
- to be able to "-x" option, I would need to have prior knowledge to use
"lua.+?stdlib" ( "lua.+?-stdlib" does not work) to give to
pkg-{info,search}.


2- How do specify the "flavor"s for various packages in a file so that I
would
not need to search or specifically have to specify them to pkg tools?

For example, something installed gcc-{9,10} as dependency, which brought in
binutils
for various platforms. If installed from devel/binutils port, it would have
installed
only "native" flavor instead of multitude of other extraneous versions.

So I would have listed "flavor" in some file (ideally suitable for both pkg
& make) so
that when "binutils" would be installed again, only one version^Wflavor of
it would
have been installed.

Not the answer that you want, but I guess that from multiple lines of
output it's possible to (at least) tell that there _exist_ flavours for
a port:

% pkg rquery --regex '%o %v %R' lua.+stdlib$ | sort
devel/lua-stdlib 41.2.2_1 FreeBSD
devel/lua-stdlib 41.2.2_1 FreeBSD
devel/lua-stdlib 41.2.2_1 FreeBSD
devel/lua-stdlib 41.2.2_1 FreeBSD
%

– then <https://www.freshports.org/devel/lua-stdlib/#flavors>.

(<https://www.freshports.org/faq.php#anchors> lists the in-page anchors
that are now available in FreshPorts.)

Old, but maybe relevant:

… can't use pkg-query(8) or pkg-rquery(8) or similar to select
and display packages according to the new metadata items like
flavor. …

(My knowledge of flavours is minimal so if that's no longer relevant,
sorry.)

Heh, you are right on both accounts.

The pkg-rquery syntax is much appreciated.

I was thinking few days ago that I should ask Dan L if he would have an API
for FreshPorts or if I would need to scrape the web pages.

Oh man! I was identifying the last quoted response in the email from
Stefan E. Thank you for the link to the past discussion.

No worries. I am with you, as I have started learning about "flavor" of a
port earnestly around middle-end of the Mar 2021 with bug 254650.

I think I might have given up on using packages largely as I had installed
poudriere earlier to build ports with options that I want, and requires too
much effort to avoid cruft.
