我可以使用Rugged或其他Ruby库创建孤立标记吗？

Question

I am trying to emulate the following in Ruby: object=$1 tag_name=$2 message=$3 user_name= git config user.name user_email= git config user.email date= date +%s

tag="object ${object}
type commit
tag ${tag_name}
tagger ${user_name} <${user_email}> ${date} +0000

${message}"

echo "${tag}" | git mktag

I have tried the following using Rugged: repo = Rugged::Repository.new(@full_path) tag_collection = Rugged::TagCollection.new(repo) annotated_tag_sha = tag_collection.create(tag_name, sha, {:message => msg, :time => Time.now}) repo.close

However the two are not equivalent. Any suggestions would be appreciated.

I did get it working locally using:

repo = Rugged::Config.global
type = "commit"
tagname = "v99.99.2"
username = repo["user.name"]
email = repo["user.email"]
message = "this is the message for the annotated tag"
tag_contents = "object f849f9e28c7f36a826d4b451efb16516c0c3acc2\ntype #    {type}\ntag #{tagname}\ntagger #{username} <#{email}> #{Time.new.to_i}     +0000\n\n#{message}"
executecommand = "printf \"#{tag_contents}\" | git mktag"
Open3.popen3(executecommand) do |stdin, stdout, stderr, wait_thr|
exit_stats = wait_thr.value
errors = stderr.readlines
puts "Errors are #{errors}"
unless exit_stats.success?
  raise Exception, 'There was an error encountered'
end
signature_file_sha = stdout.readline.chomp
puts "signature sha is #{signature_file_sha}"

end

using git 1.9 but it is throwing an error now in git 2.0.4 unable to verify object with id

Yes, you can:

# Get the repo
repo = Rugged::Repository.open("...")

# Lookup the target object
target = repo.lookup("$object")

# Create the tag annotation object
repo.tags.create_annotation("$tag_name", target, {
  tagger: {
    name: "$user_name"
    email: "$user_email",
    time: Date.parse("$date")
  },
  message: "$message"
})

I did not test this, but this should give you at least enough pointers on how to do this with rugged.
