htmlex.C File Reference

Detailed Description

This file demonstrates how THtml can document sources.

See the Users Guide chapter Automatic HTML Documentation, and THtml's class documentation.

To see this demo script in action start up ROOT and run

root [0] .x $(ROOTSYS)/tutorials/htmlex.C+

and check the output in ./htmldoc.

and of course we can put HTML code into comments, too.

 
#include "THtml.h"
 
class THtmlDemo: public TObject {
public:
   THtmlDemo(): fHtml(0)
   {
      printf("This class is for demonstration purposes only!\n");
   }
   ~THtmlDemo() { if (fHtml) delete fHtml; }
 
   // inline methods can have their documentation in front
   // of the declaration. DontDoMuch is so short - where
   // else would one put it?
   void DontDoMuch() {}
 
   void Convert()
   {
      // Create a "beautified" version of this source file.
      // It will be called htmldoc/htmlex.C.html.
 
      GetHtml()->SetSourceDir("$(ROOTSYS)/tutorials");
      GetHtml()->Convert("htmlex.C", "Example of THtml", "./htmldoc/", "./");
   }
 
   void ReferenceDoc()
   {
      // This function documents THtmlDemo.
      // It will create THtmlDemo.html and src/THtmlDemo.cxx.html
      // - the beautified version of the source file
 
      GetHtml()->SetSourceDir("$(ROOTSYS)/tutorials");
      GetHtml()->SetOutputDir("./htmldoc");
      GetHtml()->MakeIndex("THtmlDemo"); // create ClassIndex.html and the javascript and CSS files
      GetHtml()->MakeClass("THtmlDemo"); // update the class doc
   }
 
   void MakeDocForAllClasses(Bool_t evenForROOT = kFALSE)
   {

      // been loaded, and that are accessible from "./".
      // If evenForROOT is set, we'll try to document ROOT's classes,
      // too - you will end up with a copy of ROOT's class reference.
      // The documentation will end up in the subdirectory htmldoc/.
 
      if (evenForROOT)
         GetHtml()->SetSourceDir(".:$(ROOTSYS)");
