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\t2005-02-26\n+++ f2.c\t2005-02-28\n...");
    # prints "f1.c, f2.c"
    printf "%s, %s\n", $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 CWArch::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.
