[opam-devel] [ocaml-infra] Wireframe demo of OCaml.og

[Louis Gesbert]

Here is a quick & dirty shell/sed script that I used to put links to the github pages, for our projects hosted on github. Better than nothing for now.

If anyone may find it useful:

for f in **/url; do          
    homepage=$(sed \
        's#archive: *"\(http.\?://.\+\.github\.com/[^/]\+\)/.*"#\1#; t ok; s#archive: *"\(http.\?://github.com/[^/]\+/[^/]\+\)/.*"#\1#; t ok; d; :ok' $f)
    if [ -n "$homepage" ]; then
        echo -en "\e[32m$f\e[m... "
        if \! grep -q 'ocamlpro.com' ${f%url}opam; then
            echo '\e[31mNot ours\e[m'
        elif grep -q 'homepage' ${f%url}opam; then
            echo -e '\e[32mAlready there\e[m'
        else
            echo "\e[33mAdding $homepage\e[m"
            echo "homepage: \"$homepage\"" >> ${f%url}opam
        fi
    fi
done
