search for alternatives providers with xbps-query?

[classabbyamp]

xbps-query -Rp alternatives -s vi returns nothing currently (exits 2). perhaps it should search for all packages that provide the vi alternative set.

Yeah, that would be handy.

The way the packages alternatives property is setup and how we print properties would require special handling for this case.

I added a repository mode to xbps-alternatives, which provides the same functionality and fits better imho #340.

Lurking around I found this issue, and I remembered I have a patch for that dmarto@90d2891

My use case is the following script (that I use in combo with another one to find files that are not created/managed/owned by a package).

#!/bin/bash
# xalts [STRING]
#  alternatives search, prints results in xbps-query -o compatible way

while read alt; do
    [ -z "${alt}" ] && continue

    alt=${alt% (*)}

    pkg=${alt%%:*}

    real=${alt##*:}

    dir=$(dirname "$real")

    link=${alt#*: }
    link=${link%:*}
    [ "$(dirname "$link")" = "." ] && link="$dir/$link"

    echo "$pkg: $link -> $real (link)"

done <<< $(x xbps-query -R -p alternatives --search="$1")

If it is of intereset, I could open a PR.
