[Monotone-devel] Small add-on for git_export

[Yury Polyanskiy]

Hello everyone!

I thought to contribute this smallish interactive script, which I use to
manually commit signed tags after "mtn git_export".

Note: if run as "tag-script auto" it will non-interactively recommit all
of the existing lightweight tags w/o changing names. Also, best use
with gpg-agent or the analog (e.g., seahorse in gnome).

#!/bin/sh
#
# iterates over all tags in the repo and readds them as tag-objects 
#
# run as "tag-script auto" to automatically recommit lightweight tags as 
tag-objects

AUTO_NAME=0

if [ "x$1" == "xauto" ]; then
        AUTO_NAME=1
        echo "Note: automatically recomitting tags"
fi

# give this environment variable a value if you have a broken repository with 
null-names
DEFAULT_NAME=""

for CUR_TAG in `git tag`; do
        TAG_TYPE=`git cat-file -t $CUR_TAG`
        if [ "$TAG_TYPE" != "commit" ]; then
                echo ">>> tag $CUR_TAG: points to objtype $TAG_TYPE, skipping "
                continue;
        fi

        GIT_COMMITTER_NAME=`git log -1 --pretty=format:%cn $CUR_TAG`
        GIT_COMMITTER_EMAIL=`git log -1 --pretty=format:%ce $CUR_TAG`
        GIT_COMMITTER_DATE=`git log -1 --pretty=format:%ci $CUR_TAG`
        commit_id=`git log -1 --pretty=format:%H $CUR_TAG`
#       subject=`git log -1 --pretty=format:%b $CUR_TAG`
        refnames=`git log -1 --pretty=format:%d $CUR_TAG`


        if [ -z "$GIT_COMMITTER_NAME" ]; then
                GIT_COMMITTER_NAME="$DEFAULT_NAME"
        fi

        export GIT_COMMITTER_NAME GIT_COMMITTER_EMAIL GIT_COMMITTER_DATE
        echo ""
        echo ">>> tag $CUR_TAG -> commit $commit_id"
        echo "    commitref: $refnames"
#       echo "    subject  : $subject"
        echo "    committer: $GIT_COMMITTER_NAME <$GIT_COMMITTER_EMAIL>"
        echo "    date     : $GIT_COMMITTER_DATE"

        if [ "$AUTO_NAME" == "1" ]; then
                NEW_TAG="$CUR_TAG"
        else
                read -er -p "    enter new tag name (enter to skip): " NEW_TAG

                if [ -z "$NEW_TAG" ]; then
                        echo "    skipping tag-object creation";
                        continue;
                fi
        fi
        echo "    committing new tag: git tag $NEW_TAG $commit_id"
        git tag -s -m "" $NEW_TAG $commit_id
done


Best,
Yury
