class TDocParser: public TObject

 Parse C++ source or header, and extract documentation.

 Also handles special macros like

   TGMainFrame* f = new TGMainFrame(0, 100, 100);
   f->SetName("testMainFrame"); // that's part of the name of the image
   TGButton* b = new TGTextButton(f, "Test Button");

   return f; // *HIDE*
 or multiline Latex aligned at =:

C = d #sqrt{#frac{2}{#lambdaD}} #int^{x}_{0}cos(#frac{#pi}{2}t^{2})dt 
 even without alignment:
x=sin^2(y) and what about running an external macro?

TObject* testmacro()

   TH1* h = new TH1F("h", "h", 100, 0., 1.);
   TCanvas* c=new TCanvas("c","c");

   return c;

and some nested stuff which doesn't work yet:

Function documentation

TDocParser(TClassDocOutput& docOutput, TClass* cl)
 Constructor called for parsing class sources
TDocParser(TDocOutput& docOutput)
 constructor called for parsing text files with Convert()
 destructor, checking whether all methods have been found for gDebug > 3
void AddClassMethodsRecursively(TBaseClass* bc)
 Add accessible (i.e. non-private) methods of base class bc
 and its base classes' methods to methodNames.
 If bc==0, we add fCurrentClass's methods (and also private functions).
void AddClassDataMembersRecursively(TBaseClass* bc)
 Add data members of fCurrentClass and of bc to datamembers, recursively.
 Real data members are in idx 0..2 (public, protected, private access),
 enum constants in idx 3..5.
void AnchorFromLine(const TString& line, TString& anchor)
 Create an anchor from the given line, by hashing it and
 convertig the hash into a custom base64 string.
void Convert(ostream& out, istream& in, const char* relpath, Bool_t isCode, Bool_t interpretDirectives)
 Parse text file "in", add links etc, and write output to "out".
 If "isCode", "in" is assumed to be C++ code.
void DecorateKeywords(ostream& out, const char* text)
 Expand keywords in text, writing to out.
void DecorateKeywords(TString& text)
 Find keywords in line and create URLs around them. Escape characters with a
 special meaning for HTML. Protect "Begin_Html"/"End_Html" pairs, and set the
 parsing context. Evaluate sequences like a::b->c.
 Skip regions where directives are active.
void DecrementMethodCount(const char* name)
 reduce method count for method called name,
 removing it from fMethodCounts once the count reaches 0.
void DeleteDirectiveOutput() const
 Delete output generated by prior runs of all known directives;
 the output file names might have changes.
void ExpandCPPLine(TString& line, Ssiz_t& pos)
 Expand preprocessor statements

 Input: line - line containing the CPP statement,
        pos  - position of '#'

  NOTE: Looks for the #include statements and
        creates link to the corresponding file
        if such file exists

void GetCurrentModule(TString& out_module) const
 Return the name of module for which sources are currently parsed.
Bool_t HandleDirective(TString& keyword, Ssiz_t& pos, TString& word, Ssiz_t& copiedToCommentUpTo)
 Process directives to the documentation engine, like "Begin_Html" / "End_Html",
 "Begin_Macro" / "End_Macro", and "Begin_Latex" / "End_Latex".
UInt_t InContext(Int_t context) const
 checks whether we are in a parse context, return the entry closest
 to the current context.
 If context is a EParseContextFlag just look for the first match in
 the flags
void InitKeywords() const
 fill C++ keywords into fgKeywords
TClass* IsDirective(const TString& line, Ssiz_t pos, const TString& word, Bool_t& begin) const
 return whether word at line's pos is a valid directive, and returns its
 TDocDirective's TClass object, or 0 if it's not a directive. Set begin
 to kTRUE for "Begin_..."
 You can implement your own handlers by implementing a class deriving
 from TDocHandler, and calling it TDocTagDirective for "BEGIN_TAG",
 "END_TAG" blocks.
Bool_t IsName(UChar_t c)
 Check if c is a valid C++ name character

  Input: c - a single character

 Output: TRUE if c is a valid C++ name character
         and FALSE if it's not.

   NOTE: Valid name characters are [a..zA..Z0..9_~],

Bool_t IsWord(UChar_t c)
 Check if c is a valid first character for C++ name

  Input: c - a single character

 Output: TRUE if c is a valid first character for C++ name,
         and FALSE if it's not.

   NOTE: Valid first characters are [a..zA..Z_~]

TMethod* LocateMethodInCurrentLine(Ssiz_t& posMethodName, TString& ret, TString& name, TString& params, Bool_t& isconst, ostream& srcOut, TString& anchor, ifstream& sourcefile, Bool_t allowPureVirtual)
 Search for a method starting at posMethodName, and return its return type,
 its name, and its arguments. If the end of arguments is not found in the
 current line, get a new line from sourceFile, beautify it to srcOut, creating
 an anchor as necessary. When this function returns, posMethodName points to the
 end of the function declaration, i.e. right after the arguments' closing bracket.
 If posMethodName == kNPOS, we look for the first matching method in fMethodCounts.
void Parse(ostream& out)
 Locate methods, starting in the source file, then inline, then
 immediately inside the class declaration. While doing that also
 find the class description and special tags like the macro tag etc.
void LocateMethods(ostream& out, const char* filename, Bool_t lookForSourceInfo = kTRUE, Bool_t useDocxxStyle = kFALSE, Bool_t allowPureVirtual = kFALSE, const char* methodPattern = 0, const char* sourceExt = 0)
 Collect methods from the source or header file called filename.
 It generates a beautified version of the source file on the fly;
 the output file is given by the fCurrentClass's name, and sourceExt.
 Documentation is extracted to out.
   lookForSourceInfo: if set, author, lastUpdate, and copyright are
     extracted (i.e. the values contained in fSourceInfo)
   useDocxxStyle: if set, documentation can be in front of the method
     name, not only inside the method. Useful doc Doc++/Doxygen style,
     and inline methods.
   lookForClassDescr: if set, the first line matching the class description
     rules is assumed to be the class description for fCurrentClass; the
     description is written to out.
   methodPattern: if set, methods have to be prepended by this tag. Usually
     the class name + "::". In header files, looking for in-place function
     definitions, this should be 0. In that case, only functions in
     fMethodCounts are searched for.
void LocateMethodsInSource(ostream& out)
 Given fCurrentClass, look for methods in its source file,
 and extract documentation to out, while beautifying the source
 file in parallel.
void LocateMethodsInHeaderInline(ostream& out)
 Given fCurrentClass, look for methods in its header file,
 and extract documentation to out.
void LocateMethodsInHeaderClassDecl(ostream& out)
 Given fCurrentClass, look for methods in its header file's
 class declaration block, and extract documentation to out,
 while beautifying the header file in parallel.
Bool_t ProcessComment()
 Parse the current line as a comment, handling directives and re-formatting
 the comment: remove "/*", "*/", "//", similar characters surrounding lines,

 Return kFALSE if the line is not a comment.
void RemoveCommentContext(Bool_t cxxcomment)
 remove the top-most comment context that matches cxxcomment,
Bool_t Strip(TString& s)
 strips ' ', tabs, and newlines from both sides of str
void WriteClassDoc(ostream& out, Bool_t first = kTRUE)
 Write the class description depending (among others) on fClassDocState.
void WriteMethod(ostream& out, TString& ret, TString& name, TString& params, Bool_t isconst, const char* file, TString& anchor, TString& codeOneLiner)
 Write a method, forwarding to TClassDocOutput
void WriteSourceLine(ostream& out)
 Write fLineSource to out.
 Adjust relative paths first.
