Framed Document

------------------------------------------------------------------------------- One method of doing Frames (aka Netscape v2). The inital frame document needs to have a default non-frames document while most of this information is also stored in various sub-frame documents used. The problem is ensuring all these documents line up, so they contain the same indexing and data, as appropriate. EG: Frames document... =======8<--------CUT HERE----------axes/crowbars permitted--------------- Framed Document   =======8<--------CUT HERE----------axes/crowbars permitted--------------- Rather than duplicate the information in multiple places, and asking for trouble... Wirth's Rule: Never store data in more than one place, sooner or later you will update one and not the other. I created a C Perprocessed file and use #ifdef lines to mark out to what file information should be placed. Then I use CPP commands like the following to generate the various documents. /usr/lib/cpp -undef -P -DFRAME Doc.cpp | sed '/^$/d' Document.html /usr/lib/cpp -undef -P -DINDEX Doc.cpp | sed '/^$/d' Index.html /usr/lib/cpp -undef -P -DTOP Doc.cpp | sed '/^$/d' Top.html The sed part about is not needed but included to remove extra blank lines generated by cpp. Other documents types can be generated from a common source. I could have used m4 for this putpose, but found that m4 is more suited to full marco applications and has troublesome quoting. It is especially annoying to have a marco expanded when no marco was intended, particular m4's builtin marcos. Cpp is clean, and line based making it quick and simple to block out various parts.. Here is a Cpp Example for the above... This was cut down from the Frames method I use for the WWW AIcons section.
