    46    Note to customizers: the body of the webrev is IDed as SUNWwebrev

    47    to allow easy overriding by users of webrev via the userContent.css

    48    mechanism available in some browsers.

    50    For example, to have all "removed" information be red instead of

    51    brown, set a rule in your userContent.css file like:

    53        body#SUNWwebrev span.removed { color: red ! important; }

   222 # This function takes two files as arguments, obtains their diff, and

   223 # processes the diff output to present the files as an HTML document with

   224 # the files displayed side-by-side, differences shown in color.  It also

   225 # takes a delta comment, rendered as an HTML snippet, as the third

   226 # argument.  The function takes two files as arguments, then the name of

   227 # file, the path, and the comment.  The HTML will be delivered on stdout,

   228 # e.g.

   229 #

   230 #   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \

   231 #         new/usr/src/tools/scripts/webrev.sh \

   232 #         webrev.sh usr/src/tools/scripts \

   233 #         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">

   234 #          1234567</a> my bugid' > <file>.html

   235 #

   236 # framed_sdiff() is then called which creates $2.frames.html

   237 # in the webrev tree.

   238 #

   239 # FYI: This function is rather unusual in its use of awk.  The initial

   240 # diff run produces conventional diff output showing changed lines mixed

   241 # with editing codes.  The changed lines are ignored - we're interested in

   242 # the editing codes, e.g.

   243 #

   244 #      8c8

   245 #      57a61

   246 #      63c66,76

   247 #      68,93d80

   248 #      106d90

   249 #      108,110d91

   250 #

   251 #  These editing codes are parsed by the awk script and used to generate

   252 #  another awk script that generates HTML, e.g the above lines would turn

   253 #  into something like this:

   254 #

   255 #      BEGIN { printf "<pre>\n" }

   256 #      function sp(n) {for (i=0;i<n;i++)printf "\n"}

   257 #      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}

   258 #      NR==8           {wl("#7A7ADD");next}

   259 #      NR==54          {wl("#7A7ADD");sp(3);next}

   260 #      NR==56          {wl("#7A7ADD");next}

   261 #      NR==57          {wl("black");printf "\n"; next}

   262 #        :               :

   263 #

   264 #  This script is then run on the original source file to generate the

   265 #  HTML that corresponds to the source file.

   266 #

   267 #  The two HTML files are then combined into a single piece of HTML that

   268 #  uses an HTML table construct to present the files side by side.  You'll

   269 #  notice that the changes are color-coded:

   270 #

   271 #   black     - unchanged lines

   272 #   blue      - changed lines

   273 #   bold blue - new lines

   274 #   brown     - deleted lines

   275 #

   276 #  Blank lines are inserted in each file to keep unchanged lines in sync

   277 #  (side-by-side).  This format is familiar to users of sdiff(1) or

   278 #  Teamware's filemerge tool.
