NAME

Git::Annex - Perl interface to git-annex repositories

VERSION

version 0.004

SYNOPSIS

my $annex = Git::Annex->new("/home/spwhitton/annex");

# run `git annex unused` and then `git log` to get information about
# unused git annex keys
my $unused_files
  = $self->unused(used_refspec => "+refs/heads/master", log => 1);
for my $unused_file (@$unused_files) {
    say "unused file " . $unused_file->{key} . ":";
    say "";
    say "  $_" for $unused_file->{log_lines};
    say "";
    say "you can drop it with: `git annex dropunused "
      . $unused_file->{number} . "`";
    say "";
}

# embedded Git::Wrapper instance with shortcut to access annex subcommands
say for $annex->annex->find(qw(--not --in here));
$annex->annex->copy(qw(-t cloud --in here --and --lackingcopies=1));

DESCRIPTION

An instance of the Git::Annex class represents a git repository in which git annex init has been run. This module provides some useful methods for working with such repositories from Perl. See https://git-annex.branchable.com/ for more information on git-annex.

ATTRIBUTES

toplevel

The root of the repository.

git

An instance of Git::Wrapper initialised in the repository.

annex

Gives access to git-annex subcommands in the same way that Git::Annex::git gives access to git subcommands. So

$self->git->annex("contentlocation", $key);

may be written

$self->annex->contentlocation($key);

METHODS

new($dir)

Instantiate an object representing a git-annex located in $dir.

unused(%opts)

Runs git annex unused and returns a hashref containing information on unused files.

The information is cached inside the .git/annex directory. This means that a user can keep running your script without repeatedly executing expensive git annex and git log commands.

Optional arguments:

log

If true, run git log --stat -S on each unused file, to see what filenames the unused data had if and when it was used data in the annex.

Defaults to false, but if there is log data in the cache it will always be returned.

from

Corresponds to the --from option to git annex unused.

used_refspec

Corresponds to the --used-refspec option to git annex unused.

Defaults to the annex.used-refspec git config key if set, or +refs/heads/*:-refs/heads/synced/*.

abs_contentlocation($key)

Returns an absolute path to the content for git-annex key $key.

batch($cmd, @args)

Instantiate a Git::Annex::BatchCommand object by starting up a git-annex --batch command.

my $batch = $annex->batch("find", "--in=here");
say "foo/bar annexed content is present in this repo"
  if $batch->say("foo/bar");

# kill the batch process:
undef $batch;
