grit - trying to add files to git repo with out writing them to the file system

mkdir /tmp/scratch
cd /tmp/scratch
git init .

--*-- xx.rb:

SCRATCH = '/tmp/scratch'
repo = Repo.new(SCRATCH)

def add_multiple_commits_same_file_different_content(repo)
  previous_commit = repo.commits.first && repo.commits.first.id
  dir = "./"
  (0...5).each do |count|
    i1 = repo.index
    i1.read_tree('master')
    i1.add("#{dir}foo.txt", "hello foo, count is #{count}.\n")
    dir += "sd#{count}/"
    previous_commit =  i1.commit("my commit - #{count}",
                             previous_commit,
                             Actor.new("j#{count}", "e@e#{count}.zz"),
                             previous_commit.nil? ? nil : repo.commits(previous_commit).first.tree)
  end
end

add_multiple_commits_same_file_different_content(repo)

---* ---

git status:
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       deleted:    ./foo.txt
#       deleted:    ./sd0/foo.txt
#       deleted:    ./sd0/sd1/foo.txt
#       deleted:    ./sd0/sd1/sd2/foo.txt
#       deleted:    ./sd0/sd1/sd2/sd3/foo.txt
#       deleted:    ./sd0/sd1/sd2/sd3/sd4/foo.txt

---*----

Thanks John

In my opinion grit is not really following POLA so here is why how to add all changed files. My learning curve here was that Grit returned files (e.g. repo.status.files ) will not work if passed to repo.add. Instead you need to use file names. I needed to go into source code to figure this out.

location = '/foo/bar/my_repo'
repo = Grit::Repo.new(location)
# modified, added, un-tracked files
changed_files = repo.status.files.select { |k,v| (v.type =~ /(M|A)/ || v.untracked) }

Dir.chdir(location) {
  changed_files.each do |changed_file|
    # changed_file here is array, which first element is name of file 
    # e.g. changed_file.first => "example.txt."
    repo.add(changed_file.first)
  end
}

repo.commit_index("Successful commit! yeeeee! ")

I know this is an old post, but I was having the same problem and found it when searching for a solution. Looks like you need to be in the repo directory when adding the file(s). Here's what I did to make it work...

repo = Grit::Repo.init('repo/test.git')

File.open('repo/test.git/foo.txt', 'w') { |f| f.puts 'Hello World!' }

Dir.chdir('repo/test.git') { repo.add('foo.txt') }

repo.commit_index('This commit worked!')

The key step is the Dir.chdir block. Hopefully it will work for you too!
