// Name: HelpGen.cpp

// Author: Vadim Zeitlin <zeitlin@dptmaths.ens-cachan.fr>
// Modified by:
// Created: 06/01/99

/*
BUGS
1. wx/string.h confuses C++ parser terribly
2. C++ parser doesn't know about virtual functions, nor static ones
3. param checking is not done for vararg functions
4. type comparison is dumb: it doesn't know that "char *" is the same
that "char []" nor that "const char *" is the same as "char const *"
TODO (+ means fixed), see also the change log at the end of the file.
(i) small fixes in the current version
+1. Quote special TeX characters like '&' and '_' (=> derive from wxFile)
2. Document typedefs
3. Document global variables
4. Document #defines
+5. Program options
6. Include file name/line number in the "diff" messages?
+7. Support for vararg functions
(ii) plans for version 2
1. Use wxTextFile for direct file access to avoid one scan method problems
2. Use command line parser class for the options
3. support for overloaded functions in diff mode (search for OVER)
(iii) plans for version 3
1. Merging with existing files
2. GUI

Now adds 'include file' heading
Revision 1.21 2002/01/04 11:06:09 JS
Fixed missing membersections bug and also bug with functions not being written
in the right class
Revision 1.20 2002/01/03 14:23:33 JS
Added code to make it not duplicate membersections for overloaded functions
Revision 1.19 2002/01/03 13:34:12 JS

Added main() and corrected VC++ project settings
Revision 1.17 2001/11/30 21:43:35 VZ
now the methods are sorted in the correct order in the generated docs
Revision 1.16 2001/11/28 19:27:33 VZ
HelpGen doesn't work in GUI mode
Revision 1.15 2001/11/22 21:59:58 GD
use "..." instead of <...> for wx headers
Revision 1.14 2001/07/19 13:51:29 VZ
fixes to version string
Revision 1.13 2001/07/19 13:44:57 VZ
1. compilation fixes
2. don't quote special characters inside verbatim environment
Revision 1.12 2000/10/09 13:53:33 juliansmart
Doc corrections; added HelpGen project files
Revision 1.11 2000/07/15 19:50:42 cvsuser
merged 2.2 branch
Revision 1.10.2.2 2000/03/27 15:33:10 VZ
don't trasnform output dir name to lower case
Revision 1.10 2000/03/11 10:05:23 VS
now compiles with wxBase
Revision 1.9 2000/01/16 13:25:21 VS
compilation fixes (gcc)
Revision 1.8 1999/09/13 14:29:39 JS
Made HelpGen into a wxWin app (still uses command-line args); moved includes
into src for simplicity; added VC++ 5 project file
Revision 1.7 1999/02/21 22:32:32 VZ
1. more C++ parser fixes - now it almost parses wx/string.h
a) #if/#ifdef/#else (very) limited support
b) param type fix - now indirection chars are correctly handled
c) class/struct/union distinction
d) public/private fixes
e) Dump() function added - very useful for debugging
2. option to ignore parameter names during 'diff' (in fact, they're ignored
by default, and this option switches it on)
Revision 1.6 1999/02/20 23:00:26 VZ
1. new 'diff' mode which seems to work
2. output files are not overwritten in 'dmup' mode
3. fixes for better handling of const functions and operators
----------------------------
revision 1.5
date: 1999/02/15 23:07:25; author: VZ; state: Exp; lines: +106 -45
1. Parser improvements
a) const and virtual methods are parsed correctly (not static yet)
b) "const" which is part of the return type is not swallowed
2. HelpGen improvements: -o outputdir parameter added to the cmd line,
"//---------" kind comments discarded now.
----------------------------
revision 1.4
date: 1999/01/13 14:23:31; author: JS; state: Exp; lines: +4 -4
some tweaks to HelpGen
----------------------------
revision 1.3
date: 1999/01/09 20:18:03; author: JS; state: Exp; lines: +7 -2
HelpGen starting to compile with VC++
----------------------------
revision 1.2
date: 1999/01/08 19:46:22; author: VZ; state: Exp; lines: +208 -35
supports typedefs, generates "See also:" and adds "virtual " for virtual
functions
----------------------------
revision 1.1
date: 1999/01/08 17:45:55; author: VZ; state: Exp;
HelpGen is a prototype of the tool for automatic generation of the .tex files
for wxWindows documentation from C++ headers
