The actual git binary to run. By default, it is just git.
In case the git to be run is actually a command with parameters (e.g. when using <B>sudoB> or another command executer), the option value should be an array reference with the command and parameters, like this:
The current working directory in which the git command will be run.
(chdir() will be called just before launching the command.)
If not provided, it will default to the root of the Git repository work tree (if the repository is bare, then no chdir() will be performed).
|env||A hashref containing key / values to add to the git command environment.|
An arrayref containing a list of exit codes that will be considered
fatal by final_output().
Prepending the value with - will make it non-fatal, which can be useful to override a default. The string "!0" can be used as a shortcut for [ 1 .. 255 ].
If several option hashes have the fatal key, the lists of exit codes will be combined, with the values provided last taking precedence (when using a combination of positive / negative values).
The generated list always contains 128 and 129; to make them non-fatal, just add -128 and -129 to the list provided to the fatal option.
A string that is send to the git command standard input, which is then closed.
Using the empty string as input will close the git command standard input without writing to it.
Using undef as input will not do anything. This behaviour provides a way to modify options inherited from new() or a hash populated by some other part of the program.
On some systems, some git commands may close standard input on startup, which will cause a SIGPIPE when trying to write to it. This will raise an exception.
Boolean option to control the output of warnings.
If true, methods such as final_output() will not warn when Git outputs messages on STDERR.
If several option hashes are passed to new(), they will all be merged, keys in later hashes taking precedence over keys in earlier hashes.
Close all pipes to the child process, and collects exit status, etc. and defines a number of attributes (see below).
$cmd->final_output( @callbacks );
Collect all the output, and terminate the command.
Returns the output as a string in scalar context, or as a list of lines in list context. Also accepts a hashref of options.
Lines are automatically chomped.
If @callbacks is provided, the code references will be applied successively to each line of output. The line being processed is in $_, but the coderef must still return the result string.
If the Git command printed anything on stderr, it will be printed as warnings. If the git sub-process exited with a status code listed in the fatal option, it will die(). The defaults fatal exit codes are 128 (fatal error), and 129 (usage message).
The attributes of a Git::Repository::Command object are also accessible through a number of accessors.
The object returned by new() will have the following attributes defined:
Regarding the handles to the child git process, note that in the following code:
cmdline Return the command-line actually executed, as a list of strings. pid The PID of the underlying <B>gitB> command. stdin A filehandle opened in write mode to the child process standard input. stdout A filehandle opened in read mode to the child process standard output. stderr A filehandle opened in read mode to the child process standard error output.
my $fh = Git::Repository::Command->new( @cmd )->stdout;
$fh is opened and points to the output of the git subcommand, while the anonymous Git::Repository::Command object has been destroyed.
After the call to close(), the following attributes will be defined:
exit The exit status of the underlying <B>gitB> command. core A boolean value indicating if the command dumped core. signal The signal, if any, that killed the command.

The core of Git::Repository::Command has been moved into its own distribution: System::Command. Proper Win32 support is now delegated to that module.
Before that, the Win32 implementation owed a lot to two people. First, Olivier Raginel (BABAR), who provided me with a test platform with Git and Strawberry Perl installed, which I could use at any time. Many thanks go also to Chris Williams (BINGOS) for pointing me towards perlmonks posts by ikegami that contained crucial elements to a working MSWin32 implementation.
In the end, it was Christian Walder (MITHALDU) who helped me finalize Win32 support for System::Command through a quick round of edit (on my Linux box) and testing (on his Windows box) during the Perl QA Hackathon 2013 in Lancaster.
