NAME

       Arch::DiffParser - parse file's diff and perform some manipulations

SYNOPSIS

	   use Arch::DiffParser;
	   my $dp = Arch::DiffParser->new;

	   # usable for "annotate" functionality
	   my $changes = $dp->parse_file("f.diff")->changes;

	   $dp->parse($diff_content);
	   $dp->parse("--- f1.c	2005-02-26
+++ f2.c	2005-02-28
...");
	   # prints "f1.c, f2.c"
	   printf "%s, %s
", $dp->filename1, $dp->filename2;

	   # enclose lines in <span class="patch_{mod,orig,line,add,del}">
	   my $html = $dp->markup_content;

DESCRIPTION

       This class provides a limited functionality to parse a single file diff in unified format. Multiple diffs may be parsed sequentially. The
       parsed data is stored for the last diff, and is replaced on the following parse.

METHODS

       The following class methods are available:

       new, parse, parse_file, content, lines, filename1, filename2, mtime1, mtime2, hunks, changes.

       new Construct the "Arch::DiffParser" instanse.

       parse diff_content
	   Parse the diff_content and store its parsed data.

       parse_file diff_filename
	   Like parse, but read the diff_content from diff_filename.

       diff_data
	   Return hashref containing certain parsed data. Die if called before any parse methods. The keys are: "lines", "filename1", "filename2",
	   "mtime1", "mtime2", "hunks", "changes".

	   The value of "hunks" and "changes" is arrayref of arrayrefs with 5 elements: [ line-number-1, num-lines-1, line-number-2, num-lines-2,
	   "lines"-index ].

	   A "hunk" describes a set of lines containing some combination of unmodified, deleted and added lines, a "change" describes an inter-
	   hunk atom that only contains zero or more deleted lines and zero or more added lines.

       lines
       filename1
       filename2
       mtime1
       mtime2
       hunks
       changes
	   These methods are just shortcuts for diff_data->{method}.

       content [%args]
	   Return content of the last diff.

	   %args keys are "fileroot1" and "fileroot2"; if given, these will replace the subdirs "orig" and "mod" that arch usually uses in the
	   filepaths.

       markup_content [%args]
	   Like content, but every non-context line is enclosed into markup <span class="patch_name">line</span>, where name is one of "orig"
	   (filename1), "mod" (filename2), "line" (hunk linenums), "add" (added), del (deleted).

	   Not implemented yet.

BUGS

       No support for newlines in source file names yet.
