Then you can execute \fBhtags\fP from the same place. \fBHtags\fP makes an directory named \'HTML\' and generates hypertext in it. You can start browsing from \'HTML/index.html\'. .PP Since \fBhtags\fP generates static hypertext as long as the \fB-D\fP or \fB-f\fP option is not specified, you can move it anywhere and browse it by any browser without web server. .PP You must use same parser for both \fBgtags\fP(1) and \fBhtags\fP. If you use the default parser, it is not necessary to consider for it. .PP .SH OPTIONS If you are new on htags, it is recommended to invoke with the \fB--suggest\fP option. With the option, \fBhtags\fP use popular options instead of you. .br The following options are available: .TP \fB-a\fP, \fB--alphabet\fP Make an alphabetical function index which is suitable for a large project. .TP \fB--caution\fP Include caution message to prohibit downloading. .TP \fB-c\fP, \fB--compact\fP Compress html files by \fBgzip\fP(1). You need to set up a web server so that \fBgzip\fP(1) is invoked for each compressed file. See \'HTML/.htaccess\' that is generated by htags. .TP \fB-C\fP Make compressed html files with a \fIhtml.gz\fP suffix. Debian systems can usually uncompress these transparently without the need for a CGI helper. .TP \fB--cvsweb\fP \fIurl\fP Include cvsweb URL. \fIurl\fP is used as base of URL. When directory \'CVS\' exists in the root directory of source project, the content of \'CVS/Repository\' is used as the relative path from the base. .TP \fB--cvsweb-cvsroot\fP \fIcvsroot\fP Specifies cvsroot in cvsweb URL. .TP \fB-D\fP, \fB--dynamic\fP 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 directory. .TP \fB-d\fP, \fB--dbpath\fP \fIdbpath\fP Specifies the directory in which \'GTAGS\' and \'GRTAGS\' exist. The default is the current directory. .TP \fB--disable-grep\fP Disable grep in the search form(-f,--form). .TP \fB-F\fP, \fB--frame\fP Use frame for each part of the contents. .TP \fB-f\fP, \fB--form\fP Support search form using CGI program. You need to set up a web server, and you cannot move the hypertext from the source directory. .TP \fB--full-path\fP List file names with full path in the file index. By default, list just the last component of a path. .TP \fB-g\fP, \fB--gtags\fP Execute \fBgtags\fP(1) before creating hypertext. The \fB-v\fP, \fB-w\fP and \fIdbpath\fP are passed to \fBgtags\fP. .TP \fB--gtagsconf\fP \fIfile\fP Load user's configuration from \fIfile\fP. .TP \fB--gtagslabel\fP \fIlabel\fP \fIlabel\fP is used for the label of configuration file. The default is default. .TP \fB-h\fP, \fB--func-header\fP[=\fIposition\fP] Insert function header for each function. By default, \fBhtags\fP doesn't generates it. You can specify the position using \fIposition\fP argument, which allows one of before, right and after. The default position is after. .TP \fB-I\fP, \fB--icon\fP Use icons instead of text for some links. .TP \fB--insert-footer\fP \fIfile\fP Insert custom footer derived from \fIfile\fP before tag. .TP \fB--insert-header\fP \fIfile\fP Insert custom header derived from \fIfile\fP after tag. .TP \fB--item-order\fP \fIspec\fP Specify order of items in the top page. The \fIspec\fP is a string consists of item signs in order. Each sign means as follows: \fBc\fP: caution, \fBs\fP: search form, \fBm\fP: mains, \fBd\fP: definition, \fBf\fP: files. The default is \fIcsmdf\fP. .TP \fB-m\fP, \fB--main-func\fP \fIname\fP Specify the main function name. The default is main. .TP \fB-n\fP, \fB--line-number\fP[=\fIcolumns\fP] Print line numbers. By default, doesn't print line numbers. The default value of \fIcolumns\fP is 4. .TP \fB--no-map-file\fP Doesn't generate \'MAP\' and \'FILEMAP\' file. By default, \fBhtags\fP generates them. .TP \fB-o\fP, \fB--other\fP Pick up not only source files but also other files except for binary files. .TP \fB-S\fP, \fB--secure-cgi\fP \fIcgidir\fP Write CGI programs into the \fIcgidir\fP to realize a centralised CGI program. Script alias is \'/cgi-bin\' by default. You can overwrite this value using config variable script_alias in \'gtags.conf\'. .TP \fB-s\fP, \fB--symbol\fP Make anchors not only for object definitions and references but also other symbols. .TP \fB--statistics\fP Print statistics information. .TP \fB--suggest\fP \fBHtags\fP selects popular options instead of beginners. It is equivalent to '-afghInosTxv --show-position' now. .TP \fB-T\fP, \fB--table-flist\fP[=\fIfields\fP] Generate file list using tag. The \fIfields\fP is used for field number in a line. The default is 5. .TP \fB-t\fP, \fB--title\fP \fItitle\fP The \fItitle\fP of this hypertext. The default is the last component of the current directory. .TP \fB--table-list\fP List tags using

tag. .TP \fB--tabs \fInumber\fP\fP Tab stop. The default is 8. .TP \fB-v\fP, \fB--verbose\fP Verbose mode. .TP \fB-w\fP, \fB--warning\fP Print warning messages. .TP \fB-x\fP, \fB--xhtml\fP[=\fIversion\fP] Generate XHTML hypertext instead of HTML. If the \fB--frame\fP option is specified then generate XHTML-1.0 Frameset for index.html and generate XHTML-1.0 Transitional for other files, else if \fIversion\fP is 1\.1 or config variable xhtml_version is set to 1\.1 then generate XHTML-1.1 else XHTML 1.0 Transitional. .TP \fIdir\fP The directory in which hypertext is generated. The default is the current directory. .SH EXAMPLES .nf $ gtags -v $ htags -sanohITvt 'Welcome to XXX source tour!' $ firefox HTML/index.html .PP $ htags --suggest .PP .fi .SH FILES .TP \'GTAGS\' Tag file for object definitions. .TP \'GRTAGS\' Tag file for object references. .TP \'GSYMS\' Tag file for other symbols. .TP \'GPATH\' Tag file for path of source files. .TP \'/etc/gtags.conf\', \'$HOME/.globalrc\' Configuration file. .TP \'HTML/index.html\' Index file for hypertext. .TP \'HTML/MAP\' Mapping file for converting tag into path of hypertext.
