search for alternatives providers with xbps-query? #499

Open classabbyamp opened 2 years ago

classabbyamp commented 2 years ago

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 https://github.com/void-linux/xbps/pull/340.

Lurking around I found this issue, and I remembered I have a patch for that https://github.com/dmarto/xbps/commit/90d28910dc4bd49c147bc6106028192fc166ca13

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.
