/** \file help.h
|
|
* \brief Header: hypertext file browser
|
|
*
|
|
* Implements the hypertext file viewer.
|
|
* The hypertext file is a file that may have one or more nodes. Each
|
|
* node ends with a ^D character and starts with a bracket, then the
|
|
* name of the node and then a closing bracket. Right after the closing
|
|
* bracket a newline is placed. This newline is not to be displayed by
|
|
* the help viewer and must be skipped - its sole purpose is to faciliate
|
|
* the work of the people managing the help file template (xnc.hlp) .
|
|
*
|
|
* Links in the hypertext file are specified like this: the text that
|
|
* will be highlighted should have a leading ^A, then it comes the
|
|
* text, then a ^B indicating that highlighting is done, then the name
|
|
* of the node you want to link to and then a ^C.
|
|
*
|
|
* The file must contain a ^D at the beginning and at the end of the
|
|
* file or the program will not be able to detect the end of file.
|
|
*
|
|
* Lazyness/widgeting attack: This file does use the dialog manager
|
|
* and uses mainly the dialog to achieve the help work. there is only
|
|
* one specialized widget and it's only used to forward the mouse messages
|
|
* to the appropiate routine.
|
|
*
|
|
* This file is included by help.c and man2hlp.c
