Orphan Non Home Pages

It's interesting on occasion to see a list of all pages that are not pointed to by anything other than a ChangesInXXX page, and which themselves do not point to CategoryHomePage.

Obtained by a simple gawk script to process links.txt ...

    BEGIN {
        print "<html><head></head><body>"
        print "Orphan pages other than home pages. Specifically, pages<br>"
        print "on the C2 wiki that are not pointing to CategoryHomePage,<br>"
        print "and are not pointed to by anything other than ChangesInXXX.<p>"
        print "<ol>"

/CategoryHomePage/ { for (i=2;i<=NF;i++) tgts[$i] = 1 ; next } /^ChangesIn/ { next }

{ pages[$1] = $1 for (i=2;i<=NF;i++) tgts[$i] = 1 }

END { n = asort(pages) c = 0 for (i=1;i<=n;i++) { p = pages[i] if (!(p in tgts)) { print "<li><a href=\"http://c2.com/cgi/wiki?" p "\">" p "</a></li>" c++ } } print "</ol>" print c " pages, generated automatically at" system("date") print "</body></head>" }
