Name Text::Diff::HTML - XHTML 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 the appropriate XHTML elements. The elements used are 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. * "" Inserted content, each line starting with "+". * "" Deleted content, each 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 elements and 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.
