NAME

Git::Background::Future - use Future with Git::Background

VERSION

Version 0.007

SYNOPSIS

    use Git::Background 0.002;
    my $future = Git::Background->run(qw(status -s));

    my @stdout = $future->stdout;

    my ($stdout_ref, $stderr_ref, $exit_code) = $future->get;

DESCRIPTION

This is a subclass of Future. Please read the excellent documentation of Future to see what you can do with this module, this man page only describes the changes to Future specific to Git::Background.

UTF-8

The module assumes that gits output is UTF-8, which is the default. Before stdout and stderr from git are read, Git::Background turns on UTF-8 on the file handle with

    binmode($fh, ':encoding(UTF-8)');

The strings returned by the get, stderr, and stdout string can therefore contain wide characters. When you write this data to a file handle, you must ensure that the destination also uses a suitable encoding. This is necessary to correctly handle any wide characters in the data. You can do this by setting the encoding of the destination filehandle, e.g.:

    binmode(STDOUT, ':encoding(UTF-8)');

USAGE

new( RUN )

New Git::Background::Future objects should be constructed by using the run method of Git::Background.

await

Blocks and waits until the Git process finishes.

Returns the invocant future itself, so it is useful for chaining.

This method is called by get or failure.

See "await" in Future for more information.

exit_code

Calls get, then returns the exit code of the Git process.

failure

Waits for the running Git process to finish by calling await. Returns undef if the future finished successfully, otherwise it returns a list with

    $message, $category, @details

For the $category git, @details is a list of stdout_ref, stderr_ref, and exit_code.

get

Waits for the running Git process to finish by calling await. Throws a Future::Exception if the Future didn't finish successfully. Returns the stdout, stderr and exit code of the Git process.

    my $git = Git::Background->new($dir);
    my $future = $git->run('status', '-s');
    # waits for 'git status -s' to finish
    my ($stdout_ref, $stderr_ref, $rc) = $future->get;

is_done

"is_done" in Future

is_failed

"is_failed" in Future

is_ready

"is_ready" in Future

state

"state" in Future

stderr

Calls get, then returns all the lines written by the Git command to stderr.

Because this command calls get, the same exceptions can be thrown.

Note: get returns all the output lines as array reference, stderr returns a list.

stdout

Calls get, then returns all the lines written by the Git command to stdout.

Because this command calls get, the same exceptions can be thrown.

Note: get returns all the output lines as array reference, stdout returns a list.
