Name Text::Diff::HTML - HTML format for Text::Diff::Unified Synopsis use Text::Diff; my $diff = diff "file1.txt", "file2.txt", { STYLE => 'Text::Diff::HTML' }; my $diff = diff \$string1, \$string2, { STYLE => 'Text::Diff::HTML' }; my $diff = diff \*FH1, \*FH2, { STYLE => 'Text::Diff::HTML' }; my $diff = diff \&reader1, \&reader2, { STYLE => 'Text::Diff::HTML' }; my $diff = diff \@records1, \@records2, { STYLE => 'Text::Diff::HTML' }; my $diff = diff \@records1, "file.txt", { STYLE => 'Text::Diff::HTML' }; Description This class subclasses Text::Diff::Unified, a formatting class provided by the Text::Diff module, to add XHTML markup to the unified diff format. For details on the interface of the "diff()" function, see the Text::Diff documentation. In the XHTML formatted by this module, the contents of the diff returned by "diff()" are wrapped in a "
" element, as is each hunk of the diff. Within each hunk, all content is properly HTML encoded using HTML::Entities, and the various sections of the diff are marked up with "" elements. Each "
" and "" element has a class, defined as follows: "
" This element contains the entire contents of the diff "file" returned by "diff()". All of the following elements are subsumed by this one. "" The header section for the files being "diff"ed, usually something like: --- in.txt Thu Sep 1 12:51:03 2005 +++ out.txt Thu Sep 1 12:52:12 2005 This element immediately follows the opening "file" "
" element. "
" This element contains a single diff "hunk". Each hunk may contain the following "" elements: "" Header for a diff hunk. The hunk header is usually something like: @@ -1,5 +1,7 @@ This element immediately follows the opening "hunk" "
" element. "" Context around the important part of a "diff" hunk. These are contents that have *not* changed between the files being "diff"ed. "" An insertion line, starting with "+". "" A deletion line, starting with "-". "" The footer section of a hunk; contains no contents. "" The footer section of a file; contains no contents. You may do whatever you like with these classes; I highly recommend that you style them using CSS. You'll find an example CSS file in the eg directory in the Text-Diff-HTML distribution. You will also likely want to wrap the output of your diff a "
" element.
