module OhlohScm
# A +Diff+ represents a change to a single file. It can represent the addition or
# deletion of a file, or it can represent a modification of the file contents.
#
# Ohloh does not track filename changes. If a file is renamed, Ohloh treats this
# as the deletion of one file and the creation of another.
#
# Ohloh does not track directories, only the files within directories.
#
# Don't confuse our use of the word "Diff" with a patch file or the output of the
# console tool 'diff'. This object doesn't have anything to do the actual contents
# of the file; it's better to think of this object as representing a single line
# item from a source control log.
class Diff
# The filename of the changed file, relative to the root of the repository.
attr_accessor :path
# An action code describing the type of change made to the file.
# Action codes are copied directly from the Git standard.
# The action code can be...
# 'A' added
# 'M' modified
# 'D' deleted
attr_accessor :action
# The SHA1 hash of the file contents both before and after the change.
# These must be computed using the same method as Git.
attr_accessor :parent_sha1, :sha1
# For Subversion only, a path may be reported as copied from another location.
# These attributes store the path and revision number of the source of the copy.
attr_accessor :from_path, :from_revision
