Re: Re[4]: [paragui-users] script language for Paragui

[Atani]

I have looked at this and I think this would be able to generate something 
that we can use easily.  Here is an example of it parsing some of the PG 
files:


bash-2.05a$ ctags -x pgmenubar.cpp
Add              function     13 pgmenubar.cpp    void PG_MenuBar::Add(const 
char* text, PG_PopupMenu* menu, Uint16 indent, Uint16 width) {
Cleanup          function     79 pgmenubar.cpp    void PG_MenuBar::Cleanup() {
PARAGUI_CALLBACK function     57 pgmenubar.cpp    
PARAGUI_CALLBACK(PG_MenuBar::handle_button) {
PG_MenuBar       function      3 pgmenubar.cpp    
PG_MenuBar::PG_MenuBar(PG_Widget* parent, const PG_Rect& rect, const char* 
style) : PG_ThemeWidget(parent, rect, style) {
~PG_MenuBar      function      9 pgmenubar.cpp    PG_MenuBar::~PG_MenuBar() {
bash-2.05a$ ctags -x pgmenubar.h
ItemList         member       81 pgmenubar.h      std::vector<MenuBarItem*> 
ItemList;
MenuBarItem      typedef      79 pgmenubar.h      } MenuBarItem;
PG_MENUBAR_H     macro        30 pgmenubar.h      #define PG_MENUBAR_H
PG_MenuBar       class        45 pgmenubar.h      class DECLSPEC PG_MenuBar : 
public PG_ThemeWidget, public PG_EventObject {
button           member       77 pgmenubar.h      PG_Button* button; //!< 
pointer to the PG_Button object showed in the bar
my_active        member       95 pgmenubar.h      PG_PopupMenu* my_active;
my_btnOffsetY    member       83 pgmenubar.h      Uint16 my_btnOffsetY;
my_style         member       94 pgmenubar.h      std::string my_style;
popupmenu        member       78 pgmenubar.h      PG_PopupMenu* popupmenu; 
//!< pointer to the linked PG_PopupMenu object

Using this info (piped to a file and then read in) I think that parsing of 
user data files will not be a problem...

This is just using the default options (with exception of -x which generates 
user readable output) it looks pretty good...
