Usage: rdoc [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
