Script to show extension dependency tree

[ixbrian]

Here is a script that shows a dependency tree for any given extension:

get_dependencies()
{
        app=${1//KERNEL/$kernel}

        if [ "$notree" == "TRUE" ]; then
                for x in $(seq  1 $(( ${#indent} / 2 )) ); do
                        printf " "
                done           
        else
                echo -n "${BLUE}"
                echo -n "$indent"
                echo -n "-----"
                echo -n "${NORMAL}"
        fi
       
        if [ -f "$localtce"/optional/"$app" ]; then
                echo -n "${GREEN}"
        fi
       
        echo "$app"
        echo -n "${NORMAL}"

        deplist=`wget -q -O - "$MIRROR"/"$app.dep" 2>/dev/null`
        for depapp in $deplist; do
                indent="${indent}     |"
                get_dependencies $depapp
        done
        indent=${indent%     |}
}

while getopts d opts
do
        case $opts in
                d) notree="TRUE" ;;
        esac
done

shift $(expr $OPTIND - 1)

app=$1

if [ -n "$app" ]; then
        app=${app%.tcz}
        app="$app.tcz"
       
        localtce=`cat /opt/.tce_dir`
        . /etc/init.d/tc-functions
        getMirror
       
        kernel=`uname -r`
        indent=""
        get_dependencies $app
else
        echo ""
        echo "Specify extension in command line:"
        echo "Example:   $0 [-d] firefox.tcz"
        echo ""
        echo "To disable '|' and '-' display, use -d parameter"
        echo ""
fi

Here is the output the script produces:

Code: [Select]

$ ./deptree.sh firefox.tcz
-----firefox.tcz
     |-----libasound.tcz
     |-----curl.tcz
     |     |-----openssl-0.9.8.tcz

Excellent!
I admit having made use of the intermediate version of depinfo.sh which included dep tree for this purpose. Not that it really was of any harm to see the extension sizes, once one would be aware that the total comes out wrong.

I updated the script in the original post with some of the improvements that Curaga added to the depinfo.sh script.

Would it be easy to show already installed extensions in green as in depinfo.sh ?

Good idea, I will add this in and post a new version tonight. 

[ixbrian]

Updated original message with new script with the following changes:

-Installed extensions are listed in green
-You can specify extensions on the command line with or without ".tcz" file extension
-It displays an actual tree layout using "|" and "-" characters.  If you don't like this, specify the "-d" parameter to the script and it will just use spaces instead.    I'm not sure which one should be the default, the new tree layout with "|" and "-", or just spaces?

Great tool, Brian. Thanks!

Thanks for the script, ixbrian

I realize this is an old thread but thanking someone doesn't go out of date!
