#makemenu.awk -- Makes simple menu for HTML files, based on each file's , # and can make simple table of contents based on <h1>-<h6> headings. # #Typical use: # # awk -f makemenu.awk [options] infiles.html > menu.html # # Where command-line options have the form "option=value". The possible # options are title="...", toc=1, and dirprefix="..." and should appear on the # command line _before_ the names of files to be processed. # # The menu contains a list of <A HREF="file.html">....</A> elements: the # content of each of these menu items is taken from that of the # <TITLE>... element of the corresponding file. # # The title="..." option specifies the title of the menu itself: # # awk -f makemenu.awk title="Menu for HTML files" *.html > menu.html # # To make a menu of all the files in one's personal hierarchy under Unix: # # cd $HOME/public_html # awk -f makemenu.awk title="My Files" `find . -name \*.html -print` > menu.html # # The toc=1 command-line option attempts to construct a table of contents # for each file as part of the menu, based on the

If there are links inside headings, then makemenu.awk will attempt to # preserve the validity of references, and transform an # into an link to the heading from the menu file; # however, makemenu.awk is limited by the fact that it does not examine each # tag in a heading individually, but only does global search-and-replace # operations on the whole ... element (for this reason, the values # of and are only operated on if they are quoted). # # A dirprefix="..." option can also be specified on the command line; this # specifies a string which is prefixed to filenames, and which can be used to # convert local filesystem references (relative URL's) to absolute URL's. # An example: # # awk -f makemenu.awk dirprefix=http://myhost.edu/~myself/ *.html > menu.html # # This program is rather simple-minded; if an HTML file does not have a # ... element, it will not appear in the menu. If the closing # tag is not present, it will try to stuff the whole remaining text of # the file into the menu. The closing `>' character of the , , #

tags should not be on a different line from the # rest of the tag. Also, multiple headings should not be contained on a single # line. This is not an error-checking program, and illegal HTML input may # result in incorrect HTML output. # # On some systems, non-archaic awk may actually be named ``nawk''. The # ``gawk'' interpreter freely-available from the FSF GNU project is more robust # than some vendor-supplied awk/nawk interpreters. # # Copyright 1995 by H.
