5.2 Redefining functions in initialization files

To redefine a function you must replace the corresponding funtion reference with a reference on your function. Thus you should write your function, give it a name you are certain it is unique in the Texi2HTML::Config namespace, and override the value of the function reference with your own function reference. When another function from the main program (or from another functions of an initialization file) calls the reference, your function will be used.

For example the function reference corresponding with the function called when doing an anchor is called $anchor. Thus if you want to override the corresponding function you could write:

# override the function reference
$anchor = \&my_own_function;

# the function reference now refers to
sub my_own_function {
# process arguments and return an html anchor
}
