NAME

Git::Wrapper::Plus::Branches - Extract branches from Git

VERSION

version 0.001000

SYNOPSIS

This module aims to do what you want when you think you want to parse the output of

git branch

Except it works the right way, and uses

git for-each-ref

So

use Git::Wrapper::Plus::Branches;

my $branches = Git::Wrapper::Plus::Branches->new(
    git => $git_wrapper
);
# Show details of every local branch
for my $branch ( $branches->branches ) {
    printf "%s %s", $branch->name, $branch->sha1;
}
# Show details of all branches starting with master
for my $branch ( $branches->get_branch("master*") ) {
    printf "%s %s", $branch->name, $branch->sha1;
}
# Show details of current branch
for my $branch ( $branches->current_branch ) {
    printf "%s %s", $branch->name, $branch->sha1;
}

METHODS

branches

Returns a ::Branch object for each local branch.

for my $branch ( $b->branches ) {
    $branch # isa Git::Wrapper::Plus::Branch
}

get_branch

Get branch info about master

my ($branch,) = $branches->get_branch('master');

Note: This can easily return multiple values.

For instance, branches is implemented as

my ( @branches ) = $branches->get_branch('**');

Mostly, because the underlying mechanism is implemented in terms of fnmatch(3)

If the branch does not exist, or no branches match the expression, get_branch will return an empty list.

So in the top example, $branch is undef if master does not exist.

current_branch

Returns a ::Branch object if currently on a branch, undef otherwise.

my $b = $branches->current_branch;
if ( defined $b ) {
    printf "Currently on: %s", $b->name;
} else {
    print "Detached HEAD";
}
