4.2.1

Usage: rdoc2.3 [options] [names...] Files are parsed, and the information they contain collected, before any output is produced. This allows cross references between all files to be resolved. If a name is a directory, it is traversed. If no names are specified, all Ruby files in the current directory (and subdirectories) are processed. How RDoc generates output depends on the output formatter being used, and on the options you give. Options can be specified via the RDOCOPT environment variable, which functions similar to the RUBYOPT environment variable for ruby. $ export RDOCOPT="--show-hash" will make rdoc show hashes in method links by default. Command-line options always will override those in RDOCOPT. Available formatters: darkfish - HTML generator, written by Michael Granger pot - creates .pot file ri - creates ri data files RDoc understands the following file formats: - C: \.(?:([CcHh])\1?|c([+xp])\2|y)\z - ChangeLog: (/|\\|\A)ChangeLog[^/\\]*\z - Markdown: \.(md|markdown)(?:\.[^.]+)?$ - RD: \.rd(?:\.[^.]+)?$ - Ruby: \.rbw?$ - Simple: - TomDoc: Only in ruby files The following options are deprecated: --accessor support discontinued --diagram support discontinued --help-output support discontinued --image-format was an option for --diagram --inline-source source code is now always inlined --merge ri now always merges class information --one-file support discontinued --op-name support discontinued --opname support discontinued --promiscuous files always only document their content --ri-system Ruby installers use other techniques Parsing options: -e is preferred over --charset, Specifies the output encoding. All files --encoding read will be converted to this encoding. The default encoding is UTF-8. --locale=NAME Specifies the output locale. --locale-data-dir=DIR Specifies the directory where locale data live. -a, --all Synonym for --visibility=private. -x, --exclude=PATTERN Do not process files or directories matching PATTERN. -E, --extension=NEW=OLD Treat files ending with .new as if they ended with .old. Using '-E cgi=rb' will cause xxx.cgi to be parsed as a Ruby file. -U, --[no-]force-update Forces rdoc to scan all sources even if newer than the flag file. -p, --pipe Convert RDoc on stdin to HTML -w, --tab-width=WIDTH Set the width of tab characters. --visibility=VISIBILITY Minimum visibility to document a method. One of 'public', 'protected' (the default), 'private' or 'nodoc' (show everything) --markup=MARKUP The markup format for the named files. The default is rdoc. Valid values are: markdown, rd, rdoc, tomdoc --root=ROOT Root of the source tree documentation will be generated for. Set this when building documentation outside the source directory. Default is the current directory. --page-dir=DIR Directory where guides, your FAQ or other pages not associated with a class live. Set this when you don't store such files at your project root. NOTE: Do not use the same file name in the page dir and the root of your project Common generator options: -O, --force-output Forces rdoc to write the output files, even if the output directory exists and does not seem to have been created by rdoc. -f, --fmt, --format=FORMAT Set the output formatter. One of: darkfish pot ri -i, --include=DIRECTORIES Set (or add to) the list of directories to be searched when satisfying :include: requests. Can be used more than once. -C[LEVEL], Prints a report on undocumented items. --[no-]coverage-report Does not generate files. --[no-]dcov -o, --output, --op=DIR Set the output directory. -d Deprecated --diagram option. Prevents firing debug mode with legacy invocation. HTML generator options: -c, --charset=CHARSET Specifies the output HTML character-set. Use --encoding instead of --charset if available. -A, --hyperlink-all Generate hyperlinks for all words that correspond to known methods, even if they do not start with '#' or '::' (legacy behavior). -m, --main=NAME NAME will be the initial page displayed. -N, --[no-]line-numbers Include line numbers in the source code. By default, only the number of the first line is displayed, in a leading comment. -H, --show-hash A name of the form #name in a comment is a possible hyperlink to an instance method name. When displayed, the '#' is removed unless this option is specified. -T, --template=NAME Set the template used when generating output. The default depends on the formatter used. --template-stylesheets=FILES Set (or add to) the list of files to include with the html template. -t, --title=TITLE Set TITLE as the title for HTML output. --copy-files=PATH Specify a file or directory to copy static files from. If a file is given it will be copied into the output dir. If a directory is given the entire directory will be copied. You can use this multiple times -W, --webcvs=URL Specify a URL for linking to a web frontend to CVS. If the URL contains a '%s', the name of the current file will be substituted; if the URL doesn't contain a '%s', the filename will be appended to it. ri generator options: -r, --ri Generate output for use by `ri`. The files are stored in the '.rdoc' directory under your home directory unless overridden by a subsequent --op parameter, so no special privileges are needed. -R, --ri-site Generate output for use by `ri`. The files are stored in a site-wide directory, making them accessible to others, so special privileges are needed. Generic options: --write-options Write .rdoc_options to the current directory with the given options. Not all options will be used. See RDoc::Options for details. --[no-]dry-run Don't write any files -D, --[no-]debug Displays lots on internal stuff. --[no-]ignore-invalid Ignore invalid options and continue (default true). -q, --quiet Don't show progress as we parse. -V, --verbose Display extra progress as RDoc parses -v, --version print the version -h, --help Display this help
