使用Rugged / libgit2创建提交时如何更新工作目录?

我尝试使用以下测试脚本创建一个坚固的提交:

require "rugged"
r = Rugged::Repository.new(".")
index = r.index
index.read_tree(r.references["refs/heads/master"].target.tree)
blob = r.write("My test", :blob)
index.add(:oid => blob, :path => "test.md", :mode => 0100644)
tree = index.write_tree
parents = [r.references["refs/heads/master"].target].compact
actor = {:name => "Actor", :email => "actor@bla"}
options = {
    :tree => tree,
    :parents => parents,
    :committer => actor,
    :message => "message",
    :update_ref => "HEAD"
}
puts Rugged::Commit.create(r, options)

创建提交,脚本输出773d97f453a6df6e8bb5099dc0b3fc8aba5ebaa7(新提交的SHA)。生成的提交和树看起来像他们应该:

ludwig$ git cat-file commit 773d97f453a6df6e8bb5099dc0b3fc8aba5ebaa7
tree 253d0a2b8419e1eb89fd462ef6e0b478c4388ca3
parent bb1593b0534c8a5b506c5c7f2952e245f1fe75f1
author Actor <actor@bla> 1417735899 +0100
committer Actor <actor@bla> 1417735899 +0100

message
ludwig$ git ls-tree 253d0a2b8419e1eb89fd462ef6e0b478c4388ca3
100644 blob a7f8d9e5dcf3a68fdd2bfb727cde12029875260b    Initial file
100644 blob 7a76116e416ef56a6335b1cde531f34c9947f6b2    test.md

但是,工作目录未更新:

ludwig$ ls
Initial file   rugged_test.rb
ludwig$ git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    deleted:    test.md

我必须执行git reset --hard HEAD才能将丢失的文件test.md显示在工作目录中。我认为创建一个Rugged提交,并设置:update_ref => "HEAD",应该自动更新工作目录,但是必须出错,因为执行r.checkout_head也没有效果。但是,我想我正确地关注the rugged examples。我在这里缺少什么?

编辑:

ludwig$ gem list rugged

您正在采取的步骤是您不希望影响workdir或当前分支的步骤。您没有创建该文件,也没有将修改后的索引写入磁盘。

如果要将文件放在文件系统上,然后在新提交中跟踪它,请先创建文件

# Create the file and give it some content
f = open("test.md", "w")
f << "My test"
f.close

# The file from the workdir from to the index
# and write the changes out to disk
index = repo.index
index.add("test.md")
index.write

# Get the tree for the commit
tree = index.write_tree
...

然后像现在一样提交。
