From e50842fdc6700c47ba4272fad7c7dc2085d1d6e0 Mon Sep 17 00:00:00 2001 From: Kato Kazuyoshi Date: Sat, 22 Oct 2011 15:10:46 +0200 Subject: [PATCH] gitweb: add a feature to show side-by-side diff gitweb currently has a feature to show diff but it doesn't support "side-by-side" style. This modification introduces: * The "ds" query parameter to specify the style of diff. * The format_diff_chunk() to reorganize an output of diff. * The diff_nav() for form. --- gitweb/gitweb.perl | 83 ++++++++++++++++++++++++++++++++++++++++++------ gitweb/static/gitweb.css | 15 +++++++++ 2 files changed, 89 insertions(+), 9 deletions(-) diff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl index 5e4f5a0a7d..3fe4319377 100755 --- a/gitweb/gitweb.perl +++ b/gitweb/gitweb.perl @@ -757,6 +757,7 @@ our @cgi_param_mapping = ( extra_options => "opt", search_use_regexp => "sr", ctag => "by_tag", + diff_style => "ds", # this must be last entry (for manipulation from JavaScript) javascript => "js" ); @@ -1072,6 +1073,8 @@ sub evaluate_and_validate_params { } $search_regexp = $search_use_regexp ? $searchtext : quotemeta $searchtext; } + + $input_params{diff_style} ||= 'inline'; } # path to the current git repository @@ -2253,7 +2256,7 @@ sub diff_line_class { } # format patch (diff) line (not to be used for diff headers) -sub format_diff_line { +sub process_diff_line { my $line = shift; my ($from, $to) = @_; @@ -2281,7 +2284,7 @@ sub format_diff_line { } $line = "@@ $from_text $to_text @@" .
