6.5 Preparing the output

After the texinfo file has been parsed, some information is available which can be used to modify some variables and prepare the outputting. For example the document language, the document encoding, values set with @set or @setfilename and other similar @-commands are not known before the texinfo parsing.

The following function reference may be redefined to be called after texinfo processing and before document generation:

Function Reference: init_out

This function perform the initialization of variables and any other task before document outputting.

In the default case the $BODYTEXT (see section Customizing the page header) and the hashes %NAVIGATION_TEXT, %BUTTONS_NAME (see section Specifying the buttons formatting), %BUTTONS_GOTO (see section Formatting of about text) are initialized. Indeed the initialization of these variables is dependent upon the document language selection. Similarly the encoding variables are set based on the information now available (see section Setting the encodings).

To perform the default initializations and also add more code, you could do as in the following example (save the default function reference and call it in your own function) :

my $default_init_out = $init_out;
$init_out = \&makeinfo_like_init_out;
sub makeinfo_like_init_out() 
{
   &$default_init_out();
   $NAVIGATION_TEXT{'Following'} = ' > ';
}
