Few months ago, I wrote a bash script for an open-source project.

I created a small awk util that I used throughout the script to style the output. I found it very convenient. I wonder if something similar already exists.

Some screenshots in the PR: https://github.com/ricomariani/CG-SQL-author/pull/18

Let me know guys if you like it. Any comments appreciated.

    function theme() {
        ! $IS_TTY && cat || awk '

    /^([[:space:]]*)SUCCESS:/   { sub("SUCCESS:", " \033[1;32m&"); print; printf "\033[0m"; next }
    /^([[:space:]]*)ERROR:/     { sub("ERROR:", " \033[1;31m&"); print; printf "\033[0m"; next }

    /^        / { print; next }
    /^    /     { print "\033[1m" $0 "\033[0m"; next }
    /^./        { print "\033[4m" $0 "\033[0m"; next }
                { print }

    END { printf "\033[0;0m" }'
    }
