[SOLVED] How to check AUR packages in scripts?

duyinthee · 2022-12-04 01:27:39

I have a very childish script but that is helpful to me.
I know and used some AUR helper but I found they have many stuffs that I never use.
So I wrote my child play script.

#!/bin/dash

case $1 in 
    update)
        for i in $(pacman -Qm | awk '{print $1}'); do
            iv=$(pacman -Q $i | awk '{print $2}')
            cv=$(lynx -dump https://aur.archlinux.org/packages/$i | awk '/Package Details: / {print $4}')
            if [ $iv = $cv ]; then
                echo "$i ----------> UP To Date"
            else
                cdp=~/.mydir/scripts/myaurB
                [ -d $cdp ] && cd $cdp
                [ ! -d $cdp ] && mkdir $cdp && cd $cdp
                [ -d $i ] && rm -rf ./$i >> /dev/null 2>&1
                [ -e $i ] && rm -f ./$i.tar.gz >> /dev/null 2>&1
                wget https://aur.archlinux.org/cgit/aur.git/snapshot/$i.tar.gz
                tar -xzf ./$i.tar.gz
                cd ./$i
                makepkg -isc
                cd
            fi
        done
        ;;
    install)
        cdp=~/.mydir/scripts/myaurB
        [ -d $cdp ] && cd $cdp
        [ ! -d $cdp ] && mkdir $cdp && cd $cdp
        [ -d $2 ] && rm -rf ./$2 >> /dev/null 2>&1
        [ -e $2 ] && rm -f ./$2.tar.gz >> /dev/null 2>&1
        wget https://aur.archlinux.org/cgit/aur.git/snapshot/$2.tar.gz
        tar -xzf ./$2.tar.gz
        cd ./$2
        makepkg -isc
        cd
        ;;
    *)
        echo "  Do update or install <package-name> after this command."
        echo "  Eg. $ mshaur update"
        echo "  Eg. $ mshaur install pikaur"
        ;;
esac

In this script, using lynx to check the AUR package version on AUR website takes a bit time. If internet connection is slow and for 20-30 AUR packages, it takes more time.

cv=$(lynx -dump https://aur.archlinux.org/packages/$i | awk '/Package Details: / {print $4}')

So, is there any way faster and quicker to check my AUR packages' version on it AUR website page?
Thanks in advance.

Perhaps look at the code of another AUR helper and see how they do it.

Alad’s aurutils may be what you’re asking about. It’s designed in a way, that makes it suitable to be included in user’s own AUR workflow.

If writing your tools, do not download and parse pages. You’re causing unnecessary load on the service. There is an RPC interface for scripts.

Here's an excerpt of my own AUR script that checks for updates to currently installed packages. You should use the RPC interface, and you should not loop through packages, just use one call to get the info for all relevant packages:

#!/bin/sh

url='https://aur.archlinux.org/rpc?v=5&'
newer_fmt='\033[34m:: \033[0;1m%s \033[0;31m%s\033[0m -> \033[32m%s\033[0m\n'
older_fmt='\033[34m:: \033[0;1m%s \033[0m%s != %s\n'

pacman -Qm | sort >| /tmp/local.pkgs
curl -s "${url}type=info$(printf '&arg[]=%s' $(cut -f 1 /tmp/local.pkgs))" \
	| jq -r '.results[]|.Name+" "+.Version' \
	| sort | join /tmp/local.pkgs - \
	| while read pkg a b; do
			case "$(vercmp $a $b)" in
				-1) printf "$newer_fmt" "$pkg" "$a" "$b" ;;
				1)  printf "$older_fmt" "$pkg" "$a" "$b" ;;
			esac
		done

Note that most of this code is for comparing the available version to the currently installed and formatting for a colorized output. If you really just want the available versions of all your aur packages, the following would suffice:

#!/bin/sh

url='https://aur.archlinux.org/rpc?v=5&'

curl -s "${url}type=info$(printf '&arg[]=%s' $(pacman -Qmq))" \
	| jq -r '.results[]|.Name+" "+.Version'

Thank you all for replies and advice.
Yes, AUR RPC interface that is what I need.
And thanks Trilby for an excerpt of your own code. I have learnt a lot from it.
