58   Note to customizers: the body of the webrev is IDed as SUNWwebrev
59   to allow easy overriding by users of webrev via the userContent.css
60   mechanism available in some browsers.
61
62   For example, to have all "removed" information be red instead of
63   brown, set a rule in your userContent.css file like:
64
65       body#SUNWwebrev span.removed { color: red ! important; }

592# sdiff_to_html
593#
594# This function takes two files as arguments, obtains their diff, and
595# processes the diff output to present the files as an HTML document with
596# the files displayed side-by-side, differences shown in color.  It also
597# takes a delta comment, rendered as an HTML snippet, as the third
598# argument.  The function takes two files as arguments, then the name of
599# file, the path, and the comment.  The HTML will be delivered on stdout,
600# e.g.
601#
602#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
603#         new/usr/src/tools/scripts/webrev.sh \
604#         webrev.sh usr/src/tools/scripts \
605#         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">
606#          1234567</a> my bugid' > <file>.html
607#
608# framed_sdiff() is then called which creates $2.frames.html
609# in the webrev tree.
610#
611# FYI: This function is rather unusual in its use of awk.  The initial
612# diff run produces conventional diff output showing changed lines mixed
613# with editing codes.  The changed lines are ignored - we're interested in
614# the editing codes, e.g.
615#
616#      8c8
617#      57a61
618#      63c66,76
619#      68,93d80
620#      106d90
621#      108,110d91
622#
623#  These editing codes are parsed by the awk script and used to generate
624#  another awk script that generates HTML, e.g the above lines would turn
625#  into something like this:
626#
627#      BEGIN { printf "<pre>\n" }
628#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
629#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
630#      NR==8           {wl("#7A7ADD");next}
631#      NR==54          {wl("#7A7ADD");sp(3);next}
632#      NR==56          {wl("#7A7ADD");next}
633#      NR==57          {wl("black");printf "\n"; next}
634#        :               :
635#
636#  This script is then run on the original source file to generate the
637#  HTML that corresponds to the source file.
638#
639#  The two HTML files are then combined into a single piece of HTML that
640#  uses an HTML table construct to present the files side by side.  You'll
641#  notice that the changes are color-coded:
642#
643#   black     - unchanged lines
644#   blue      - changed lines
645#   bold blue - new lines
646#   brown     - deleted lines
647#
648#  Blank lines are inserted in each file to keep unchanged lines in sync
649#  (side-by-side).  This format is familiar to users of sdiff(1) or
650#  Teamware's filemerge tool.
