Direzione di ricerca

Start with the xbps-query modes described in the issue and the xbps-query(1) documentation, comparing the output behavior of -l, -s, -m, -O, -X, and -x. Review the related issues and pull request before defining the scope. Done should mean the package-listing modes have predictable default and secondary output formats, with the chosen flags documented.

Descrizione

enhancement

Right now, xbps-query has different default output formats (or even only one output format) for some commands.

Multiple columns:

[root@rootfs /]# xbps-query -l
ii acl-2.3.1_1                     Access Control List filesystem support
ii acpid-2.0.33_2                  ACPI Daemon (acpid) With Netlink Support
...

[root@rootfs /]# xbps-query -s ab
[*] bash-completion-2.11_2         Programmable completion for the GNU Bash shell
[*] bzip2-1.0.8_1                  Freely available, patent free, high-quality data compressor
...

Single column:

[root@rootfs /]# xbps-query -m  # same for -O and -X
acpid-2.0.33_2
base-voidstrap-0.11_1
...

[root@rootfs /]# xbps-query -x sway
swaybg>=0
xorg-server-xwayland>=0
...

I think it would be nice if the first two examples (-l and -s) had the same output format. Maybe we can introduce a new "package state descriptor" like nn or -- for "currently not installed" packages? Right now we have, according to xbps-query(1):

         ii Package is installed.
         uu Package is unpacked but must be configured with xbps-reconfigure(1).
         hr Package is half-removed, and can be fully removed with xbps-remove(1).
         ?? Package state is unknown.

Overall, I think it would be useful to have two different easily reachable output formats (by easily reachable I mean e.g. a simple flag, not a complete --format=... specifier). Often, e.g. when searching packages via -s, additional information like the short description and package version is useful. But often it is also useful to just have a list of package names (without any version string etc.) for batch processing, e.g. saving a list of all manually installed packages to be later fed into xbps-install on another system. I think these are two common scenarios, and having only two default output formats for the various package listing options of xbps-query will make it easier (because more predictable) to use. The flags could be named -v|--verbose (already exists, but maybe it could be used for this) and -q|--quiet. Some modes, like -s, are verbose by default and can be made shorter using -q. And some modes, like -m, are short by default and can be made more verbose using -v.

There was also the (IMO great) idea of adding a --format=... option, however I'm talking about the default output format and perhaps an easily reachable secondary one, for the most common cases.
