:hp2.Welcome to DocView!:ehp2.
:p.
DocView is a program for reading fpGUI or OS/2 (aka eComStation) Help
Files. Both the INF and OS/2 HLP file formats can be read.
:p.:link reftype=hd refid='Support'.Support and Licensing:elink.
:p.:link reftype=hd refid='Using'.Using DocView:elink.
:p.:hp1.To stop this file appearing when you start DocView without specifying a
help file, see "Settings - Options - General" tab.:ehp1.
:p.
:hp2.History:ehp2.
:p.
DocView was originally based on the OS/2 NewView program. It was ported from
the Sibyl development environment, to the fpGUI Toolkit and the Free Pascal Compiler. Since then the code
and features of DocView has diverged.
:p.
It improves upon many aspects of the origin IBM View program, with a modern,
easy to use interface, more options, and new features that View simply
didn't have. And don't forget, DocVIew is also cross platform - currently available
as native executable for Linux, FreeBSD and Windows. DocView is also available in
32-bit or 64-bit.

:p.DocView is Copyright 2009-2010 by Graeme Geldenhuys. It is also licensed
under the GNU Public License v2, which means you have the right to obtain the
source code.
:p.
DocView is part of the fpGUI Toolkit project and is the default help viewer for
any fpGUI based applications. Source code for DocView is available in the fpGUI
git repository on SourceForge.net, inside the :hp1.docview:ehp1. directory.
:p.
If you find DocView helpful, please email me and/or make a
donation to support further development. It's nice to hear from
you!
:ul.
:li.Project is hosted on SourceForge.net at http://sourceforge.net/projects/fpgui/
:li.Suggestions, compliments or bug reports can be left on the fpGUI support newsgroups.
The news server is accessible via NNTP at news://opensoft.homeip.net/
.br
There is also a web interface to the NNTP news server for those behind company
firewalls. http://opensoft.homeip.net/webnews/
:li.Translate DocView to your language.
:li.A donation to fpGUI development. You can contact me via email at: graemeg@gmail.com
:eul.
:p.:hp2.Reporting Bugs:ehp2.
:p.If you need to report a crash or other problem, then be as specific as
possible about what files were being used, what you were doing,
etc. If at all possible, compile DocView with debug information and supply a
backtrace. This will greatly help me fix problems.
:p.
If it is specific to a particular help file, then send them to me via email.
:p.
It would be helpful if you could include the following information with your
bug report:
:ul.
:li.DocView version (Help - Product Information)
:li.The file names of the help files you have problems with.
:li.A screenshot may be useful, if the problem is an incorrect or corrupt
display.
:eul.
:p.:hp2.Why doesn't my help file work properly?:ehp2.
:p.Some of the less used features of the original View program are not
implemented. This is either because I have not got around to it, or
because they are simply not worth the time. Examples include
metafiles, index synonyms, application control API (like toolbar button customisation),
MDI style window management and so on.
:p.Unfortunately, IBM seems to have used every one of these features in there INF
documents, so you may find an occasional file that doesn't
load or doesn't work properly.
:p.:hp2.Features still planned?:ehp2.
:ul.
:li.Image support. The Ric Text View component can already handle images, I am only struggling
to decode the images inside INF help files. This should hopefully be fixed soon.
:li.Bookmark support
:li.Annotations of help files
:li.Printing support
:li.Cross-file linking. Clicking a hyperlink that automatically opens another
INF help file and goes to the correct topic. DocView already supports loading
multiple files, so this is almost complete.
:li.Some optimization of the Rich Text View component. Better startup time, improved
text wrapping and font substitution support.
:eul.

.* Using DocView
.* ************************************************************
:h1 res=2 id='Using'.Using DocView
:hp2.Using DocView:ehp2.
:p.
Once you have :link reftype=hd refid='OpeningFiles'.opened a
file:elink., you can read it in various ways.
:p.
You can read the :link reftype=hd refid='contents'.table of
contents:elink., use the :link reftype=hd refid='Index'.alphabetical
index:elink., or :link reftype=hd refid='search'.search:elink..
:p.
To simply read the help file like a paper book, use the "Previous"
.*  :artwork runin name='images\previous.bmp'.
 and "Next"
.*  :artwork runin name='images\next.bmp'.
 buttons to work your way through all the topics. They are the Up and Down arrow
 buttons on the toolbar.
:p.You can also use the help file like web pages, using "Back"
.*  :artwork runin name='images\back.bmp'.
 and "Forward"
.*  :artwork runin name='images\forward.bmp'.
 buttons to go back to wherever you were before, or to retrace your
steps. They are the Left and Right arrow buttons on the toolbar.
:p.
Colours and some of the behaviour of DocView can be adjusted from the "Tools
- Options" menu.
.* TODO
.* :p.You can also :link reftype=hd refid='notes'.annotate:elink. or :link
.*reftype=hd refid='bookmarks'.bookmark:elink. topics.


.* ************************************************************
.* Opening Help File
.* ************************************************************
:h1 res=3 id='OpeningFiles'.
Opening Files
:i1 id=30005.open
:p.:hp2.Opening Help Files:ehp2.
:p.
To open a help file, you can use any of the following:
:ul.
:li.Double-click a :link reftype=hd refid='HelpIcons'.help icon:elink. that is
already set up. The DocView executable needs to be associated with INF files in
your desktop environment.
:li.Type "docview :hp1.filename:ehp1." from the :link reftype=hd
refid='CommandLine'.command line:elink..
:li.Click the Open button
.*  :artwork runin name='images\open.bmp'.
 from within DocView, or the "File - Open" menu item.
:li.Click the "File - Open additional file" menu item to open more files, without
closing the already opened files.
:li.Click the "File - Open Special" to load help files based on an Environmnt Variable
that was previous set.
:li.Reload a recently viewed file from the "File - Open Recent" menu.
:eul.
:p.
Once the file is loaded, you should see the :link reftype=hd
refid='contents'.table of contents:elink. and the first help topic.
:p.
:hp2.Loading Multiple Files Together:ehp2.
:p.
DocView can load multiple files at once, presenting them as if they
were one book, and read environment variables for filenames.
:p.
For example, on my system I can do the following:
:xmp.
  docview FPCHELP
:exmp.
which loads the whole Free Pascal help library on my system. FPCHELP is an environment
variable set in ~/.profile (Linux) or config.sys (Windows) consisting of "rtl+fcl+ref"
which tells DocView to load the help files rtl.inf, fcl.inf and ref.inf. The
files are searched for in the path specified by two :link
reftype=hd refid='L_EnvironmentVariables'.environment
variables:elink..
:p.
The files are all loaded and effectively appended to each other.
:p.
Being able to load multiple files like this can be helpful for various
reasons. For example, I use this method to integrate DocView with the various IDE's
(Integrated Development Environments) I use. I can then easily search for help on
language keywords, source code classes or units etc.
:p.
You can also open additional help files by selecting the "File - Open additional file"
menu option.
.* TODO
.* :p.
.* When you click a link to a different help file&comma. DocView loads the other
.* file without closing your current files&per.
:p.
At any time, you can find out what files are open by using the "Help - Show help
file header info" menu option.
:p.
:hp2.Loading Additional Files:ehp2.
:p.
You can select the "File - Open additional file" menu option, and DocView will
open the file you have selected without closing the currently opened files.
.*  TODO
.*  :p.:hp2.Drag and Drop:ehp2.
.*  :p.You can drag and drop &per.INF or &per.HLP files onto DocView and they will
.*  be opened&per. If you hold down the Shift key&comma. they will be opened without
.*  closing the current files&per.
.*  :p.You can drop files onto any of the main content areas&comma. such as the
.*  Contents or Index windows&comma. or an existing topic window&per.
.*  :note text='Note:'.Some links that go across files&comma. will only work if the correct set of
.*  files is loaded&per.


.* ************************************************************
.* Help Icons
.* ************************************************************
:h2 res=17 id='HelpIcons'.Help Icons
:hp2.Help Icons:ehp2.
:p.
Help Icons on the desktop are usually "program shortcuts" or "filesystem objects".
Details on how to create a program shortcut for DocView, or how to associate INF
files to be opened with DocView, is beyond the scope of this document. Please see the
help of your operating system for more information.
:p.
Saying that, with the fpGUI source code, in the "docview/install" directory, there is some
information on how to setup a Gnome desktop with DocView. Unfortunately those
instructions don't seem to work on all Linux or FreeBSD systems, so you again need
to refer to your desktop system's help for guidance.
.*  :p.Some programs create these icons automatically at install time&per.
.*  :p.You can create these icons yourself by using the desktop program
.*  template&per. See desktop help for more information&per.
.*  :p.If you create icons by dragging help files to the desktop&comma. then you
.*  cannot give them a meaningful title&comma. because that would change the name of
.*  the file&comma. which might prevent programs from finding the help file&per.
.*  Therefore program objects are currently the recommended means of creating help
.*  icons&per.


.* ************************************************************
.* Navigation Panel Tabs
.* ************************************************************
:h1 res=200 id='NavigationPanel'.Navigation Panel Tabs
:hp2.Navigation Panel Tabs:ehp2.
:p.
The left hand panel contains several tabs for moving through the current help
file in different ways.
:ul.
:li.:link reftype=hd refid='contents'.Contents:elink.
:li.:link reftype=hd refid='index'.Index:elink.
:li.:link reftype=hd refid='search'.Search:elink.
:li.:link reftype=hd refid='notes'.Notes:elink.
:li.:link reftype=hd refid='history'.History:elink.
:eul.
:p.You can hide this panel to get more space, by draging the splitter bar
.*  :artwork runin name='images\navigator.bmp'. or by selecting View
to the left, or simply double-clicking on the splitter bar. To show the Left Panel
again, drag the splitter bar to the right.
:p.
The last location of the splitter bar (width of the Left Panel) is remembered
between DocView sessions. So when you open DocView, the Left Panel is the same
width as the last time you used DocView.
.*  TODO
.*  :p.You can stop the navigation panel from appearing when a help file is opened
.*  in Tools &endash. Options &endash. General tab&per.


.* ************************************************************
.* Contents View
.* ************************************************************
:h2 res=4 id='contents'.Contents View
:i1 id=30006.Table of Contents
:hp2.Table of Contents:ehp2.
:p.
Most help files have a table of contents that shows you the topics in the
file, in a hierarchy or "tree". This is usually the first view you see
when you open a file.
:p.
You can expand or collapse branches on the tree by clicking the [+] or
[-] buttons, or using the left and right arrow keys on the keyboard.
:p.
To view a topic from the contents, just click on it. You can also
move through the contents by using the arrow keys.
:p.
To move through :hp2.all:ehp2. topics in the contents tree, in
order, you can use the
.*  TODO
.*  Ctrl &plus. Up and Ctrl &plus. Down&comma. or the
"Previous"
.*  :artwork runin name='images\previous.bmp'.
 and "Next"
.*  :artwork runin name='images\next.bmp'.
 buttons on the toolbar. This is one way to treat the help file as a normal book, reading
through each page.
:p.
You can also review the whole table of contents by using "Expand All" in the
tree view's popup menu. This expands all the branches of the contents table so you can
quickly look through it. However, it's usually easier to use
:link reftype=hd refid='search'.Search:elink. or :link reftype=hd
refid='Index'.Index:elink. for this purpose.

.* ************************************************************
.* Index
.* ************************************************************
:h2 res=5 id='index'.Index
:hp2.About the Index:ehp2.
:p.
The Index tab contains an alphabetical listing of topics or keywords in the
help file. You can quickly search through it just by typing the first few
characters of the word you want to look up. DocView jumps to the first match
in the index automatically. To view the highlighted topic, press
enter.
:note text='Note:'.
Help files may or may not include an "official" index. The index is
manually created by the author, so (for the original OS/2 View program) it's
usefulness is strictly dependent on how much work the author put into it.
There may not even be Index information in the help file.
:p.
However, a useful index can be provided simply by listing the titles of
each topic alphabetically, and this is what DocView does. It then
merges the original index (if any) with the list of topic titles.
:p.
If for some reason you don't like this, you can change this behaviour in
"Settings - Options - General" tab. There are three options to choose from.
:dl tsize=16.
:dt.Alphabetical
:dd.All topics from the table of content are sorted and displayed as an Index.
:dt.File Only
:dd.Only the "official" index created by the author of the help file is used. Some
help files don't include an official index, so then the Index listbox will be empty.
:dt.Full
:dd.Both the topics and the official index are combined to display a larger and
more useful Index to the user. This is the default option.
:edl.

.* ************************************************************
.* Search
.* ************************************************************
:h2 res=6 id='search'.Search
:hp2.Searching:ehp2.
:p.
Searching is a quick way to find information, when you don't know
where to start. Simply go to the Search tab, type some related words
and press Enter, or click the Go button.
You'll see a listing of all topics containing that word, or words
like it, with the best matches at the top. The best match will be
displayed automatically.
:p.
Words that matches your search are highlighted in the topic.
.*  TODO
.*  :p.
.*  :hp2.Global search:ehp2.
.*  :p.You can also search all help files on your system using the :link reftype=hd
.*  refid='GlobalSearch'.global search:elink. in "Settings - Search all Help
.*  Files".
:p.
:hp2.Phrase search:ehp2.
:p.
If you want to search for a phrase made up of more than one word, put
double quotes around it, for example "os/2 warp".
:p.
:hp2.Matching features:ehp2.
:p.
DocView allows you finer control of searching. You can add either of the two symbols
directly infront of a word (no spaces between symbol and word), to narrow down
a search even more.
:dl compant tsize=15.
:dt.+ (plus sign)
:dd.indicates a word that :hp2.must:ehp2. be matched
:dt.- (minus sign)
:dd.indicates a word that must :hp2.not:ehp2. be matched
:edl.
:p.
To make searching even more useful, DocView implements a special search algorithm
which does partial word matches. That is, if you search for "win", DocView will
also find "window", "following", "showing" etc. However, the better the match is the higher
the rank will be. The search rank is displayed in square brackets behind each
search result. Searches are :hp2.not:ehp2. case-sensitive.
:p.
:hp2.How DocView ranks results:ehp2.
:p.DocView ranks matching topics by various means:
:ul.
:li.a closer match to a full word
:li.number of matching words in a topic
:li.matches within the title
:li.matches within an index entry
:eul.

Writing Help Files
:p.:hp2.Writing OS&slash.2 Help Files :ehp2.
:p.
:p.OS&slash.2 Help Files are produced using the IPF Compiler&per. IPF stands for
Information Presentation Facility&per.
:p.The IPF Compiler takes a text file written in a language that tells it about
things like headings&comma. links&comma. text and images&comma. and produces
either a &per.INF or &per.HLP file&per.
:p.The official way to obtain the IPF compiler &lpar.ipfc&per.exe&rpar. is from
the OS&slash.2 Developers Toolkit&per. This is included free with eComStation
&lpar.http&colon.&slash.&slash.www&per.ecomstation&per.com&rpar.&per.
:p.Since the language for IPFC is tedious &lpar.for example all punctuation must
be typed as special keywords&comma. like &amp.comma&per.&rpar. many people use
other tools besides the IPF compiler itself&per.
:p.I use Vyperhelp
&lpar.http&colon.&slash.&slash.www&per.vyperhelp&per.com&rpar. since it is
simple and graphical&per. It can also export to Windows Help&comma. HTML and
others&comma. though it only runs on OS&slash.2&per. Not free&per.
:p.Some other popular options are&colon.
:p.o HyperText&slash.2 IPF Preprocessor
&lpar.http&colon.&slash.&slash.www&per.clanganke&per.de&slash.os2&slash.sw&slash.htext&slash.

&rpar. &endash. preprocesses a simpler starting language into the very difficult
IPF format&per. Free&per.
:p.o HyperMake
&lpar.http&colon.&slash.&slash.www&per.hypermake&per.com&rpar.&per.
Similar&comma. but can also produce Windows Help and HTML&per.
:p.o Sibyl &lpar.which DocView was created with&rpar. comes with an IPF

&rpar.&per. Probably the most complete&comma. but significant cost&per.
