NAME

VCI::Abstract::Diff - An object representing a "diff" or "patch" from a Version-Control System

SYNOPSIS

 my $diff = $commit->as_diff;

 my $file_changes = $diff->files;
 foreach my $file (@$files) {
     my $changes = $file->changes;
     my $path    = $file->path;
 }

 my $text = $diff->raw;

DESCRIPTION

Every VCS can generate a patch in "diff" format that can be applied to re-create the changes in a particular commit.

This class represents the actual changes made to each file in a commit, and can also be represented in "diff" format.

METHODS

Accessors

All accessors are read-only.

files

An arrayref of VCI::Abstract::Diff::File objects, which each represent the changes made to that particular file.

Files that were added but have no contents aren't tracked in the Diff.

Note that changes to binary files aren't tracked.

raw

The exact text of the diff, as it would be returned by the version-control system. If will be in unified diff format, but other details of the format of the patch may be specific to the VCS.

project

The VCI::Abstract::Project that this Diff is from.

For Subclass Implementors

If you are just a user of VCI::Abstract::Diff, you don't need to read about these.

_transform_filename: To make implementing this class easier, you can override this function to transform the filenames that appear in the patch into filenames relative to the root of your Project.

CLASS METHODS

Constructor

Usually you won't construct an instance of this class directly, but instead, use "as_diff" in VCI::Abstract::Commit.

new: Takes all "Accessors" as named parameters. The following fields are required: "raw", and "project".
