Legacy ROOT documentation system.
- Deprecated:
- We keep THtml for those who still need it for legacy use cases. ROOT has since several years moved to doxygen as documentation generator. THtml is not developed nor supported anymore; please migrate to doxygen instead.
The THtml class is designed to easily document classes, code, and code related text files (like change logs). It generates HTML pages conforming to the XHTML 1.0 transitional specifications; an example of these pages is ROOT's own reference guide. This page was verified to be valid XHTML 1.0 transitional, which proves that all pages generated by THtml can be valid, as long as the user provided XHTML (documentation, header, etc) is valid. You can check the current THtml by clicking this icon:

Behind the scenes
I. Usage
These are typical things people do with THtml:
root[] THtml html; // create a THtml object
root[] html.LoadAllLibs(); // Load all rootmap'ed libraries
root[] html.MakeAll(); // generate documentation for all changed classes
or to run on just a few classes:
root[] THtml html; // create a THtml object
root[] html.MakeIndex(); // create auxiliary files (style sheet etc) and indices
root[] html.MakeClass("TMyClass"); // create documentation for TMyClass only
To "beautify" (i.e. create links to documentation for class names etc) some text file or macro, use:
root[] html.Convert( "hsimple.C", "Histogram example" )
Most configuration options can be set as a call to THtml, or as a TEnv variable, which you can set in your .rootrc.
II.1 Input files
In your .rootrc, define Root.Html.SourceDir to point to directories containing .cxx and .h files (see: TEnv) of the classes you want to document, or call THtml::SetInputDir()
Example:
Root.Html.SourceDir: .:src:include
Root.Html.Root: http://root.cern.ch/root/html
II.2 Output directory
The output directory can be specified using the Root.Html.OutputDir configuration variable (default value: "htmldoc"). If that directory doesn't exist THtml will create it.
Example:
Root.Html.OutputDir: htmldoc
II.3 Linking other documentation
When trying to document a class, THtml searches for a source file in the directories set via SetInputDir(). If it cannot find it, it assumes that this class must have been documented before. Based on the library this class is defined in, it checks the configuration variable Root.Html.LibName, and creates a link using its value. Alternatively, you can set these URLs via THtml::SetLibURL().
Example:
If a class MyClass is defined in class mylibs/libMyLib.so, and .rootrc contains
Root.Html.MyLib: ../mylib/
THtml will create a link to "../mylib/MyClass.html".
The library name association can be set up using the rootmap facility. For the library in the example above, which contains a dictionary generated from the linkdef MyLinkdef.h, the command to generate the rootmap file is
$ rlibmap -f -r rootmap -l mylib/libMyLib.so -d libCore.so -c MyLinkdef.h
Here, -r specifies that the entries for libMyLib should be updated, -l specifies the library we're dealing with, -d its dependencies, and -c its linkdef. The rootmap file must be within one of the LD_LIBRARY_PATH (or PATH for Windows) directories when ROOT is started, otherwise ROOT will not use it.
II.4 Recognizing class documentation
The class documentation has to appear in the header file containing the class, right in front of its declaration. It is introduced by a string defined by Root.Html.Description or SetClassDocTag(). See the section on documentation syntax for further details.
Example:
Root.Html.Description: //____________________
The class documentation will show which include statement is to be used and which library needs to be linked to access it. The include file name is determined via TClass::GetDeclFileName(); leading parts are removed if they match any of the ':' separated entries in THtml::GetIncludePath().
II.5 Author, copyright, etc.
During the conversion, THtml will look for some strings ("tags") in the source file, which have to appear right in front of e.g. the author's name, copyright notice, etc. These tags can be defined with the following environment variables: Root.Html.Author, Root.Html.LastUpdate and Root.Html.Copyright, or with SetAuthorTag(), SetLastUpdateTag(), SetCopyrightTag().
If the LastUpdate tag is not found, the current date and time are used. This is useful when using THtml::MakeAll()'s default option force=kFALSE, in which case THtml generates documentation only for changed classes.
Authors can be a comma separated list of author entries. Each entry has one of the following two formats
-
Name (non-alpha).
THtml will generate an HTML link for Name, taking the Root.Html.XWho configuration variable (defaults to "http://consult.cern.ch/xwho/people?") and adding all parts of the name with spaces replaces by '+'. Non-alphanumerical characters are printed out behind Name.
Example:
// Author: Enrico Fermi appears in the source file. THtml will generate the link http://consult.cern.ch/xwho/people?Enrico+Fermi. This works well for people at CERN.
-
Name <link> Info.
THtml will generate an HTML link for Name as specified by link and print Info behind Name.
Example:
// Author: Enrico Fermi <http://www.enricos-home.it> or
// Author: Enrico Fermi <enric.nosp@m.o@fn.nosp@m.al.go.nosp@m.v> in the source file. That's world compatible.
Example (with defaults given):
Root.Html.Author: // Author:
Root.Html.LastUpdate: // @(#)
Root.Html.Copyright: * Copyright
Root.Html.XWho: http://consult.cern.ch/xwho/people?II.6 Header and footer
THtml generates a default header and footer for all pages. You can specify your own versions with the configuration variables Root.Html.Header and Root.Html.Footer, or by calling SetHeader(), SetFooter(). Both variables default to "", using the standard Root versions. If it has a "+" appended, THtml will write both versions (user and root) to a file, for the header in the order 1st root, 2nd user, and for the footer 1st user, 2nd root (the root versions containing "<html>" and </html> tags, resp).
If you want to replace root's header you have to write a file containing all HTML elements necessary starting with the <doctype> tag and ending with (and including) the <body> tag. If you add your header it will be added directly after Root's <body> tag. Any occurrence of the string TITLE% in the user's header file will be replaced by a sensible, automatically generated title. If the header is generated for a class, occurrences of CLASS% will be replaced by the current class's name, SRCFILE% and INCFILE% by the name of the source and header file, resp. (as given by TClass::GetImplFileName(), TClass::GetDeclFileName()). If the header is not generated for a class, they will be replaced by "".
Root's footer starts with the tag <!–SIGNATURE–>. It includes the author(s), last update, copyright, the links to the Root home page, to the user home page, to the index file (ClassIndex.html), to the top of the page and this page is automatically generated information. It ends with the tags </body></html>. If you want to replace it, THtml will search for some tags in your footer: Occurrences of the strings AUTHOR%, UPDATE%, and COPYRIGHT% are replaced by their corresponding values before writing the html file. The AUTHOR% tag will be replaced by the exact string that follows Root.Html.Author, no link generation will occur.
II.7 Links to searches, home page, ViewVC
Additional parameters can be set by Root.Html.Homepage (address of the user's home page), Root.Html.SearchEngine (search engine for the class documentation), Root.Html.Search (search URL, where u is replaced by the referer and s by the escaped search expression), and a ViewVC base URL Root.Html.ViewCVS. For the latter, the file name is appended or, if the URL contains f, f is replaced by the file name. All values default to "".
Examples:
Root.Html.Homepage: http://www.enricos-home.it
Root.Html.SearchEngine: http://root.cern.ch/root/Search.phtml
Root.Html.Search: http://www.google.com/search?q=%s+site%3A%uII.8 HTML Charset
XHTML 1.0 transitional recommends the specification of the charset in the content type meta tag, see e.g. http://www.w3.org/TR/2002/REC-xhtml1-20020801/ THtml generates it for the HTML output files. It defaults to ISO-8859-1, and can be changed using Root.Html.Charset.
Example:
Root.Html.Charset: EUC-JPIII. Documentation syntax
III.1 Class description
A class description block, which must be placed before the first member function, has a following form:
////////////////////////////////////////////////////////////////
// //
// TMyClass //
// //
// This is the description block. //
// //
////////////////////////////////////////////////////////////////
The environment variable Root.Html.Description (see: TEnv) contains the delimiter string (default value: //_________________). It means that you can also write your class description block like this:
//_____________________________________________________________
// A description of the class starts with the line above, and
// will take place here !
//
Note that everything until the first non-commented line is considered as a valid class description block.
III.2 Class index
All classes to be documented will have an entry in the ClassIndex.html, showing their name with a link to their documentation page and a miniature description. This description for e.g. the class MyClass has to be given in MyClass's header as a comment right after ClassDef(MyClass, n).
III.3 Method documentation
A member function description block starts immediately after '{' and looks like this:
void TWorld::HelloWorldFunc(string *text)
{
// This is an example of description for the
// TWorld member function
helloWorld.Print( text );
}
Like in a class description block, everything until the first non-commented line is considered as a valid member function description block.
If the rootrc variable Root.Html.DescriptionStyle is set to Doc++ THtml will also look for method documentation in front of the function implementation. This feature is not recommended; source code making use of this does not comply to the ROOT documentation standards, which means future versions of THtml might not support it anymore.
III.4 Data member documentation
Data members are documented by putting a C++ comment behind their declaration in the header file, e.g.
int fIAmADataMember; // this is a data member
IV. Documentation directives
NOTE that THtml does not yet support nested directives (i.e. latex inside html etc)!
IV.1 BEGIN_HTML END_HTML: include 'raw' HTML
You can insert pure html code into your documentation comments. During the generation of the documentation, this code will be inserted as is into the html file.
Pure html code must be surrounded by the keywords BEGIN_HTML and END_HTML, where the case is ignored. An example of pure html code is this class description you are reading right now. THtml uses a TDocHtmlDirective object to process this directive.
IV.2 BEGIN_MACRO END_MACRO: include a picture generated by a macro
THtml can create images from scripts. You can either call an external script by surrounding it by "begin_macro"/"end_macro", or include an unnamed macro within these keywords. The macro should return a pointer to an object; this object will then be saved as a GIF file.
Objects deriving from TGObject (GUI elements) will need to run in graphics mode (non-batch). You must specify this as a parameter: "Begin_macro(GUI)...". To create a second tab that displays the source of the macro you can specify the argument "Begin_macro(source)...". Of course you can combine them, e.g. as "Begin_macro(source,gui)...". THtml uses a TDocMacroDirective object to process this directive.
This is an example:
END_HTML BEGIN_MACRO(source) { TCanvas* macro_example_canvas = new TCanvas("macro_example_canvas", "", 150, 150); macro_example_canvas->SetBorderSize(0); macro_example_canvas->SetFillStyle(1001); macro_example_canvas->SetFillColor(kWhite); macro_example_canvas->cd(); TArc* macro_example_arc = new TArc(0.5,0.32,0.11,180,360); macro_example_arc->Draw(); TEllipse* macro_example_ellipsis = new TEllipse(0.42,0.58,0.014,0.014,0,360,0); macro_example_ellipsis->SetFillStyle(0); macro_example_ellipsis->Draw(); macro_example_ellipsis = new TEllipse(0.58,0.58,0.014,0.014,0,360,0); macro_example_ellipsis->SetFillStyle(0); macro_example_ellipsis->Draw(); macro_example_ellipsis = new TEllipse(0.50,0.48,0.22,0.32,0,360,0); macro_example_ellipsis->SetFillStyle(0); macro_example_ellipsis->Draw(); TLine* macro_example_line = new TLine(0.48,0.53,0.52,0.41); macro_example_line->Draw(); return macro_example_canvas; } END_MACRO
BEGIN_HTML
IV.3 BEGIN_LATEX END_LATEX: include a latex picture
You can specify TLatex style text and let THtml convert it into an image by surrounding it by "Begin_Latex", "End_Latex". You can have multiple lines, and e.g. align each line at the '=' sign by passing the argument separator='='. You can also specify how to align these parts; if you want the part left of the separator to be right aligned, and the right part to be left aligned, you could specify align='rl'. THtml uses a <a href="http://root.cern.ch/root/html/TDocLatexDirective.html">TDocLatexDirective</a> object to process the directive. This is an example output with arguments ‘separator=’=', align='rl':
‘ END_HTML BEGIN_LATEX(separator=’=', align='rl')#kappa(x)^{2}=sin(x)^{x} x=#chi^{2} END_LATEX
BEGIN_HTML
V. Product and module index
THtml::MakeIndex() will generate index files for classes and types, all modules, and the product which you can set by THtml::SetProductName(). THtml will make use of external documentation in the module and product index, either by linking it or by including it. The files for modules are searched based on the source file directory of the module's classes.
A filename starting with "index." will be included in the index page; all other files will be linked. Only files ending on .html or .txt will be taken into account; the text files will first be run through THtml::Convert(). You can see an example here; the part between "Index of HIST classes" and "Jump to" is created by parsing the module's doc directory.
VI. Auxiliary files: style sheet, JavaScript, help page
The documentation pages share a common set of javascript and CSS files. They are generated automatically when running MakeAll(); they can be generated on demand by calling CreateAuxiliaryFiles().
VII. Class Charts
THtml can generate a number of graphical representations for a class, which are displayed as a tabbed set of imaged on-top of the class description. It can show the inheritance, inherited and hidden members, directly and indirectly included files, and library dependencies.
These graphs are generated using the Graphviz package. You can install it from http://www.graphviz.org. You can either put it into your $PATH, or tell THtml where to find it by calling SetDotDir().
Here is a list of all configuration variables that are known to THtml. You can set them in your .rootrc file, see TEnv.
Root.Html.OutputDir (default: htmldoc)
Root.Html.SourceDir (default: .:src/:include/)
Root.Html.Author (default: // Author:) - start tag for authors
Root.Html.LastUpdate (default: // @(#)) - start tag for last update
Root.Html.Copyright (default: * Copyright) - start tag for copyright notice
Root.Html.Description (default: //____________________ ) - start tag for class descr
Root.Html.HomePage (default: ) - URL to the user defined home page
Root.Html.Header (default: ) - location of user defined header
Root.Html.Footer (default: ) - location of user defined footer
Root.Html.Root (default: ) - URL of Root's class documentation
Root.Html.SearchEngine (default: ) - link to the search engine
Root.Html.Search (default: ) - link to search by replacing "%s" with user input
Root.Html.ViewCVS (default: ) - URL of ViewCVS base
Root.Html.XWho (default: http://consult.cern.ch/xwho/people?) - URL of CERN's xWho
Root.Html.Charset (default: ISO-8859-1) - HTML character set
IX. Behind the scene
Internally, THtml is just an API class that sets up the list of known classes, and forwards API invocations to the "work horses". TDocOutput generates the output by letting a TDocParser object parse the sources, which in turn invokes objects deriving from TDocDirective to process directives.
