NAME

Git::Class::Cmd

SYNOPSIS

use strict;
use warnings;
use Git::Class;

my $git = Git::Class::Cmd->new;
my $worktree = $git->clone('git://github.com/charsbar/git-class.git');

my $captured = $git->status; # as a whole
my @captured = $git->status; # split by "\n"

# other interface, mainly for internal use
my $cmd = Git::Class::Cmd->new( die_on_error => 1, verbose => 1 );
$cmd->git( commit => { message => 'a commit message', all => '' } );

DESCRIPTION

This is a simple wrapper of a git executable. The strength is that you can run a git command and capture the output in a simple and more portable way than using open to pipe (which is not always implemented fully).

As of this writing, most of the git commands (methods of this class) simply returns the output, but this will be changed in the near future, especially when called in the list context, where we may want sort of proccessed data like what files are affected etc.

METHODS

Most of the git commands are implemented as a role. See Git::Class::Role::* for details.

is_available

returns true if the git command exists (or specified explicitly).

git

takes a git command name (whatever git executable recognizes; it doesn't matter if it's implemented in this package (as a method/role) or not), and options/arguments for that.

Options may be in a hash reference (or hash references if you prefer). You don't need to care about the order and shell-quoting, and you don't need to prepend '--' to the key in this case, but you do need to set its value to a blank string("") (or undef) if the option doesn't take a value. Of course you can pass option strings merged in the argument list.

Note that if you want to pass options for git executable (instead of git command options), pass them as a hash reference first, before you pass a command string, and command parameters.

$cmd->git({ git_dir => '/path/to/repo/' }, 'command', ...);

Returns a captured text in the scalar context, or split lines in the list context. If some error (or warnings?) might occur, you can see it in $object->_error.

Note that if the $object->is_verbose, the captured output is printed as well. This may help if you want to issue interactive commands.

If you want to trace commands, set GIT_CLASS_TRACE environmental variable to true.
