In advance of using this command, you must execute @xref{gtags,1} from the root directory of the source tree. Then you can execute @name{htags} from the same place. @name{Htags} makes an directory named @file{HTML} and generates hypertext in it. You can start browsing from @file{HTML/index.html}. Since @name{htags} generates static hypertext as long as the @option{-D} or @option{-f} option is not specified, you can move it anywhere and browse it with any browser without web server. You must use same parser for both @xref{gtags,1} and @name{htags}. If you use the default parser, it is not necessary to consider for it.@OPTIONS The following options are available: @begin_itemize @item{@option{-a}, @option{--alphabet}} Make an alphabetical function index which is suitable for a large project. @item{@option{--caution}} Include caution message to prohibit downloading. @item{@option{-c}, @option{--compact}} Compress html files by @xref{gzip,1}. You need to set up a web server so that @xref{gzip,1} is invoked for each compressed file. See @file{HTML/.htaccess} that is generated by htags. @item{@option{--cvsweb} @arg{url}} Include cvsweb URL. @arg{url} is used as base of URL. @item{@option{--cvsweb-cvsroot} @arg{cvsroot}} Specifies cvsroot in cvsweb URL. @item{@option{-D}, @option{--dynamic}} Generate object lists dynamically using CGI program. By default, object lists are generated statically. Though this option decrease both the size and the generation time of the hypertext, you need to set up a web server, and you cannot move the hypertext from the source directroy. @item{@option{-d}, @option{--dbpath} @arg{dbpath}} Specifies the directory in which @file{GTAGS} and @file{GRTAGS} exist. The default is the current directory. @item{@option{-f}, @option{--form}} Support search form using CGI program. You need to set up a web server, and you cannot move the hypertext from the source directroy. @item{@option{-F}, @option{--frame}} Use frame for each part of the contents. @item{@option{-g}, @option{--gtags}} Execute @xref{gtags,1} before creating hypertext. The @option{-v}, @option{-w} and @arg{dbpath} are passed to @name{gtags}. @item{@option{--gtagsconf} @arg{file}} Load user's configuration from @arg{file}. @item{@option{--gtagslabel} @arg{label}} @arg{label} is used for the label of configuration file. The default is @code{default}. @item{@option{--insert-header} @arg{file}} Insert custom header derived from @arg{file} after <body> tag. @item{@option{--insert-footer} @arg{file}} Insert custom footer derived from @arg{file} before </body> tag. @item{@option{-m}, @option{--main-func} @arg{name}} Specify the main function name. The default is @code{main}. @item{@option{-n}, @option{--line-number}} Print line numbers. By default, doesn't print them. @item{@option{--no-map-file}} Doesn't generate @file{MAP} and @file{FILEMAP} file.

If you use the @option{--xhtml} option, you should use @file{style.css} instead. @item{@option{-s}, @option{--symbol}} Make anchors not only for functions but also other symbols. @file{GSYMS} tag file needed. @item{@option{-S}, @option{--secure-cgi} @arg{cgidir}} Write CGI programs into the @arg{cgidir} to realize a centralised CGI program. Script alias is @file{/cgi-bin} by default. You can overwrite this value using config variable @code{script_alias} in @file{gtags.conf}. @item{@option{-t}, @option{--title} @arg{title}} The @arg{title} of this hypertext. The default is the last component of the current directory. @item{@option{-v}, @option{--verbose}} Verbose mode. @item{@option{-w}, @option{--warning}} Print warning messages. @item{@option{-x}, @option{--xhtml}} Generate XHTML hypertext instead of HTML. If the @option{--frame} option is specified then generate XHTML-1.0 Frameset for index.html and generate XHTML-1.0 Transitional for other files, else if config variable @code{xhtml_version} is set to @code{1.1} then generate XHTML-1.1 else XHTML 1.0 Transitional. @item{@arg{htmldir}} The directory in which hypertext is generated.
