.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Gjdoc can be used in two ways: as a stand-alone documentation tool, or
as a driver for a user-specified Doclet.
.PP
In the default mode, Gjdoc will use the Standard Doclet
\&\fBHtmlDoclet\fR to generate a set of \s-1HTML\s0 pages.  The canonical
usage is:
.PP
.Vb 1
\&        gjdoc \-s src/java/ \-all \-d api\-docs/
.Ve
.PP
Here, \fBsrc/java/\fR is the root of your source code class
hierarchy, \fB\-all\fR means that all valid Java files found under
this root directory should be processed, and \fBapi\-docs/\fR is the
directory where the generated documentation should be placed.
.PP
To learn more about running Doclets other than the Standard Doclet,
refer to the manual.

.IX Item "-s pathlist"
.PD 0
.IP "\fB\-sourcepath\fR \fIpathlist\fR" 4
.IX Item "-sourcepath pathlist"
.PD
Look for source files in the specified directory or directories.
.Sp
\&\fIpathlist\fR should be one or more directory paths separated by your
platform's path separator (usually \fB:\fR or \fB;\fR).
.Sp
If this option is not given, \fBgjdoc\fR will look for source
files in the current directory.
.Sp
The directories specified should be root directories in terms of the
Java package system.  For example, if you want to generate
documentation for classes in package \fBfoo.bar\fR, you must specify
the directory containing the top-level \fB\f(BIfoo\fB\fR
sub-directory, not the directory \fB\f(BIfoo/bar/\fB\fR in which the
Java source files reside.
.Sp
The short-hand alias \fB\-s\fR is specific to \fBgjdoc\fR and
not compatible to Sun \fBjavadoc\fR.
.IP "\fB\-all\fR" 4
.IX Item "-all"
\&\fI[\s-1EXPERIMENTAL\s0]\fR
Process all valid Java source files found in the directories listed in
the source path and their sub-directories.
.Sp
This is an option specific to \fBgjdoc\fR and not compatible to
Sun \fBjavadoc\fR.
.IP "\fB\-subpackages\fR \fIpkg:pkg:...\fR" 4
.IX Item "-subpackages pkg:pkg:..."
Process the classes in the given Java packages and all sub-packages,
recursively.  Note that multiple package names must be separated with
colons instead of whitespace.
.IP "\fB\-exclude\fR \fIpkg:pkg:...\fR" 4
.IX Item "-exclude pkg:pkg:..."
Do not process classes in the given Java packages and all
sub-packages, recursively.  This option can be used in conjunction
with \fB\-all\fR or \fB\-subpackages\fR in order to exclude
individual packages or package sub-trees from the output.
.IP "\fIpackages\fR\fB...\fR" 4
.IX Item "packages..."
Process all classes in the given Java packages.
.IP "\fIsourcefiles\fR\fB...\fR" 4
.IX Item "sourcefiles..."
Process the classes in the given Java source files.
.SS "Specifying the Format of Input Files"
.IX Subsection "Specifying the Format of Input Files"
.IP "\fB\-source\fR \fIrelease\fR" 4
.IX Item "-source release"
Assume that the source files are targeted at the given release of the
Java platform.
.Sp
\&\fIrelease\fR should be the version number of a Java platform release
in the format \s-1MAJOR\s0.MINOR, for example \fB1.4\fR.
.Sp
This option is currently ignored except that an error is raised if a
release number other than \fB1.2\fR, \fB1.3\fR or \fB1.4\fR is
specified.
.IP "\fB\-encoding\fR \fIcharset\fR" 4
.IX Item "-encoding charset"
Assume that the source files are encoded using \fIcharset\fR.
.Sp
Examples for \fIcharset\fR are \fBUS-ASCII\fR, \fB\s-1ISO\-8859\-1\s0\fR or
\&\fB\s-1UTF\-8\s0\fR.
.Sp
The semantics of \fIcharset\fR are identical to those of \fBjava.nio.charset.Charset.forName(String)\fR.
.IP "\fB\-breakiterator\fR" 4
.IX Item "-breakiterator"
Use the locale's java.text.BreakIterator instead of the internal
first sentence detector.
.Sp
By default, \fBgjdoc\fR uses an internal algorithm to determine
where a sentence ends. When this option is given, it will instead use
the \fBjava.text.BreakIterator\fR instance for the locale given with
\&\fB\-locale\fR (or the default locale).
.Sp
This option should be specified when applying \fBgjdoc\fR to
source code commented in a non-latin language for which the default
first sentence detector does not work. For all other cases, the
default (do not use BreakIterator) produces better results at the time
of this writing.
.SS "Interlinking with other Documentation Sets"
.IX Subsection "Interlinking with other Documentation Sets"
.IP "\fB\-link\fR \fIurl\fR" 4
.IX Item "-link url"
Create hyperlinks to another documentation set.
.Sp
By default, \fBgjdoc\fR will only create hyperlinks to classes in
the source set.  Use this option to additionally create hyperlinks to
classes covered by the specified documentation set.
.Sp
\&\fIurl\fR should be the root \s-1URL\s0 of the other documentation set. For
example, to add hyperlinks to \s-1GNU\s0 Classpath, specify the following:
.Sp
.Vb 1
\&        \-link http://developer.classpath.org/doc/
.Ve
.Sp
The \fB\-link\fR option can be specified multiple times.
.Sp
Note that specifying the \fB\-link\fR option will cause an \s-1HTTP\s0
access every time gjdoc is invoked. You can use \fB\-linkoffline\fR
instead to avoid this access.
.IP "\fB\-linkoffline\fR \fIurl\fR\fB \fR\fIfile\fR" 4
.IX Item "-linkoffline url file"
Create hyperlinks to another documentation set which is also present
on the local file system.
.Sp
This option works exactly like \fB\-link\fR, except that it accesses
the local file system instead of the network for determining which
classes are covered by the linked documentation set.
.Sp
When using \fB\-linkoffline\fR the remote documentation set is not
accessed at all, which can significantly speed up generation time
depending on your network connection.  The generated hyperlinks to the
documentation set however refer to the remote set, not to the local
one, so that you can distribute the documentation without any further
dependencies.
.Sp
The \fB\-linkoffline\fR option can be specified multiple times.
.IP "\fB\-noqualifier\fR \fIpkg:pkg:...\fR" 4
.IX Item "-noqualifier pkg:pkg:..."
Do not qualify names of classes in the given packages with their
package name.
.Sp
By default, a class name is displayed unqualified only if the class is
part of the source set or a linked documentation set, and qualified
with the name of its containing package if it is not. You can use this
option to force unqualified names for classes even if they are not
part of the documentation set.
.Sp
For example, usually a reference to the String class is represented
fully-qualified as \fBjava.lang.String\fR (unless you link to the
appropriate documentation set using \fB\-link\fR) because it isn't
part of the documentation set.  You can specify \fB\-noqualifier
java.lang\fR to render the same references just as \fBString\fR.
.Sp
Note that for all unqualified class names, a tooltip is provided when
you place your mouse pointer over it in the \s-1HTML\s0 documentation.
.IP "\fB\-noqualifier\fR \fBall\fR" 4
.IX Item "-noqualifier all"
Omit package name qualifier from all class names.
.Sp
Specify this option to omit package name qualifiers altogether,
.SS "Selecting which Information to Generate"
.IX Subsection "Selecting which Information to Generate"
.IP "\fB\-public\fR" 4
.IX Item "-public"
Only include public members of public classes in the output.  By
default, protected class members are included as well.
.IP "\fB\-protected\fR" 4
.IX Item "-protected"
Include public or protected members of public classes in the output.
This is the default.
.IP "\fB\-package\fR" 4
.IX Item "-package"
Include public, protected and package-private members of public and
package-private classes.
.IP "\fB\-private\fR" 4
.IX Item "-private"
Include all classes and class members regardless of their access
level.
.IP "\fB\-splitindex\fR" 4
.IX Item "-splitindex"
Generate one index page per letter instead of a single, monolithic
index page.
.Sp
By default, the index created by the Standard Doclet contains all
entries on a single page.  This is fine for small documentation sets,
but for large sets you should specify this option.
.IP "\fB\-nosince\fR" 4
.IX Item "-nosince"
Ignore \fB\f(CB@since\fB\fR tags in javadoc comments.
.Sp
By default, the generated output contains sections listing the version
of your \s-1API\s0 since which the package, class or class member in question
exists when this tag is encountered.  Specify this option to omit this
information.
.IP "\fB\-notree\fR" 4
.IX Item "-notree"
Do not generate any tree pages.
.Sp
By default, the generated output includes one inheritance tree per
package, and \- if the documentation set consists of multiple packages
\&\- a page with the full inheritance tree.  Specify this option to omit
generation of these pages.
.IP "\fB\-noindex\fR" 4
.IX Item "-noindex"
Do not output the alphabetical index.
.Sp
By default, gjdoc generates an alphabetical index of all program
elements in the documentation set (packages, classes, inner classes,
constructors, methods, and fields).  Specify this option to omit this
information.
.IP "\fB\-nohelp\fR" 4
.IX Item "-nohelp"
Do not generate the help page.
.Sp
This option is currently ignored as the Standard Doclet doesn't
provide a help page.
.IP "\fB\-nodeprecated\fR" 4
.IX Item "-nodeprecated"
Do not output inline information about deprecated packages, classes or
class members.
.Sp
By default, the Standard Doclet adds a highlighted paragraph with
deprecation information to the description of each deprecated program
element.  Specify this option to omit this information.
.IP "\fB\-nodeprecatedlist\fR" 4
.IX Item "-nodeprecatedlist"
Do not output the summary page for deprecated \s-1API\s0 elements.
.Sp
By default, the Standard Doclet generates a page listing all
deprecated \s-1API\s0 elements along with a deprecation description which
usually includes the reason for deprecation and possible
alternatives.  Specify this option to omit this information.
.IP "\fB\-nonavbar\fR" 4
.IX Item "-nonavbar"
Do not output the navigation bar, header, and footer.
.Sp
By default, each output page is equipped with a top navigation bar
(which may include a user-specified header) and a bottom navigation
bar (which may include a user-specified footer).  Specify this option
to omit this decoration.
.IP "\fB\-nocomment\fR" 4
.IX Item "-nocomment"
Omit all documentation text from the generated files and output only
declarations and program element relationships.
.Sp
This option is here for compatibility with \fBjavadoc\fR.  If you
plan on extracting information about your project via \fBgjdoc\fR,
you should consider using a different Doclet for your purposes
instead, for example XmlDoclet.  You could also use the Doclet \s-1API\s0
directly by implementing a new Doclet.
.IP "\fB\-linksource\fR" 4
.IX Item "-linksource"
Generate a page with syntax-highlighted source code for each class.
By default, this page is not generated.
.Sp
The source code can be accessed by clicking on the button labelled
\&\*(L"Source\*(R" in the navigation bar, or by clicking on the name of a
constructor, field, method, or inner class in the detail section of a
class documentation page.
.IP "\fB\-use\fR" 4
.IX Item "-use"
Generate a page with cross-reference information. By default, this
page is not generated.
.Sp
The cross-reference information can be accessed by clicking on the
button labelled `Use' in the navigation bar.
.Sp
The `Use' page lists all classes/interfaces in the documentation set
that extend/implement the class (type) in question; fields of the
type; methods or constructors accepting a parameter of the type;
methods returning the type; and methods or constructors throwing the
type.
.IP "\fB\-author\fR" 4
.IX Item "-author"
Include author information in the output.
.Sp
When specified, author information as specified using the
\&\fB\f(CB@author\fB\fR tag in javadoc comments is incorporated into the
output. By default, \fB\f(CB@author\fB\fR tags are ignored.
.IP "\fB\-version\fR" 4
.IX Item "-version"
Include version information in the output.
.Sp
When specified, version information as specified using the
\&\fB\f(CB@version\fB\fR tag in javadoc comments is incorporated into the
output. By default, \fB\f(CB@version\fB\fR tags are ignored.
.IP "\fB\-licensetext\fR" 4
.IX Item "-licensetext"
Assume that the first comment in each source file contains the license
text, and add license information to the footer of each generated
class page.
.Sp
This is an option specific to \fBgjdoc\fR and not compatible to
Sun \fBjavadoc\fR.
.Sp
This option is intended for use with free and open source projects
where source code is typically prefixed with a boilerplate license
comment, when there are legal reasons for including the license in the
documentation.
.IP "\fB\-docfilessubdirs\fR" 4
.IX Item "-docfilessubdirs"
Recursively copy all files in the \fIdoc-files\fR sub-directory of each
package directory.
.Sp
Usually, only the files in the \fIdoc-files\fR sub-directory are copied
without descending recursively.
.IP "\fB\-excludedocfilessubdir\fR \fIname\fR\fB:\fR\fIname\fR\fB:...\fR" 4
.IX Item "-excludedocfilessubdir name:name:..."
Do not copy some directories directly under the \fIdoc-files\fR
sub-directories when descending recursively.
.Sp
The argument to this option should be a colon-separated list of
directory names.
.Sp
This option only makes sense if \fB\-docfilessubdirs\fR is also
specified.  In this case, any sub-directory located directly beneath a
\&\fIdoc-files\fR directory is omitted if listed.
.SS "Custom Documentation Tags"
.IX Subsection "Custom Documentation Tags"
.IP "\fB\-tagletpath\fR \fIpathlist\fR" 4
.IX Item "-tagletpath pathlist"
Search \fIpathlist\fR when loading subsequent Taglet classes specified
using \fB\-taglet\fR.
.Sp
\&\fIpathlist\fR should be one or more paths to a directory or jar file,
separated by your platform's path separator (usually \fB:\fR or
\&\fB;\fR).
.IP "\fB\-taglet\fR \fIclassname\fR" 4
.IX Item "-taglet classname"
Register a Taglet.
.Sp
\&\fIclassname\fR should be the fully-qualified name of a Java class
implementing \fBcom.sun.tools.doclets.Taglet\fR.
.Sp
The Taglet classes will be loaded from the classpath specified using
\&\fB\-tagletpath\fR, from the classpath specified using
\&\fB\-classpath\fR and from the default classpath.
.Sp
See the documentation of \fBcom.sun.tools.doclets.Taglet\fR for
further information.

\&\fItaghead\fR is the string to display in the header of the section
devoted to the tag in question.
.Sp
For example, to define a tag matching \fB\f(CB@cvsid\fB\fR which is to be
accepted in overview, package and type pages and which is labelled
with the header \fB\s-1CVS\s0 \s-1ID\s0\fR, you would specify:
.Sp
.Vb 1
\&        \-tag cvsid:tpo:"CVS ID"
.Ve
.Sp
Let's say that a class javadoc comment contains
.Sp
.Vb 1

The given stylesheet is simply loaded by each \s-1HTML\s0 page in addition to
the default ones, as the last stylesheet.
.Sp
Note that the \s-1CSS\s0 cascading rules apply.  That is, your style
properties will only be assigned if they have a higher cascading order

The first argument should be a short plain text which is used as the
title of the package group.  The second argument should be a
colon-separated list of package wildcards.  The group will consist of
all packages in the documentation set whose name matches any of the
given wildcards.
.Sp
There is only one wildcard character, \fB*\fR, which matches both
letters in package name components and the \fB.\fR separating package
name components.  For example, \fBj*regex\fR would match package
\&\fBjava.util.regex\fR.  A more useful example would be

This option can be used to supply a description of the documentation
set as a whole.

When specified, the first sentence of the fragment will be put above
the tables listing the documented packages, along with a link to the

\&\fIname\fR should be a locale specifier in the form \fBll_CC[_VAR]\fR
where \fBll\fR is a lowercase two-letter \s-1ISO\-639\s0 language code,
\&\fB\s-1CC\s0\fR is an optional uppercase two-letter \s-1ISO\-3166\s0 country code,
and \fB\s-1VAR\s0\fR is an optional variant code.  For example, \fBen\fR
specifies English, \fBen_US\fR specifies \s-1US\s0 English, and
\&\fBen_US_WIN\fR specifies a deviant variant of the \s-1US\s0 English locale.
.Sp
Note that the semantics of this option correspond exactly to those of
the constructors of class \fBjava.util.Locale\fR.

This option currently only determines which Collator is being used for
sorting output elements.  This means that the locale will only have an

If this option is not given, the encoding specification in output
\&\s-1XHTML\s0 is chosen to match the encoding used when writing the file (the
encoding given with \fB\-docencoding\fR, or your platform's default
encoding).
.Sp
The semantics for \fIcharset\fR are specified here:
<\fBhttp://www.w3.org/TR/2000/REC\-xml\-20001006#NT\-EncName\fR>.  For
all practical purposes, they are identical to those of the other
options accepting charset parameters.

This option is here for compatibility with \fBjavadoc\fR and
should be avoided.
.IP "\fB\-docencoding\fR \fIcharset\fR" 4
.IX Item "-docencoding charset"
Use the given charset encoding when writing output files instead of
your platform's default encoding.

Examples for \fIcharset\fR are \fBUS-ASCII\fR, \fB\s-1ISO\-8859\-1\s0\fR or
\&\fB\s-1UTF\-8\s0\fR.

The semantics of this option correspond exactly to those of the
constructors of class \fBjava.util.Locale\fR.
.IP "\fB\-validhtml\fR" 4
.IX Item "-validhtml"
Force generation of valid \s-1XHTML\s0 code.  This breaks compatibility to
the traditional Javadoc tool to some extent.
.Sp
If this option is specified, anchor names will be mangled so that they
are valid according to the \s-1XHTML\s0 1.1 specification.  However, a
documentation set generated with this option cannot be linked to
properly using the traditional Javadoc tool.  It can be linked to just
fine using Gjdoc, though.
.Sp
Without this option, anchor names for executable class members use the
traditional format, for example: \*(L"foo(String,int[])\*(R".  This is
compatible to the traditional Javadoc tool, but according to both the
\&\s-1HTML\s0 4.0 and \s-1XHTML\s0 1.0 and 1.1 specifications, this format includes
illegal characters.  Parentheses, square brackets, and the comma are
not allowed in anchor names.
.IP "\fB\-baseurl\fR \fIurl\fR" 4
.IX Item "-baseurl url"
Hardwire a page \s-1URL\s0 relative to \fIurl\fR into each generated page.
.Sp
If you are generating documentation which will exclusively be
available at a certain \s-1URL\s0, you should use this option to specify this
\&\s-1URL\s0.

This can help avoid certain redirect attacks used by spammers, and it
can be helpful for certain web clients.

Sun's \fBjavadoc\fR tool seems to be based on \fBjavac\fR and
as such it seems to operate on the \s-1VM\s0 level.  \fBgjdoc\fR, in
contrast, is a pure Java application.

Therefore, \fBgjdoc\fR can only fake, or simulate, the following
VM-level options.
.IP "\fB\-classpath\fR \fIpathlist\fR" 4
.IX Item "-classpath pathlist"
Set the Virtual Machine \fBclasspath\fR to \fIpathlist\fR.

In most cases you should use \fB\-docletpath\fR or
\&\fB\-tagletpath\fR instead of this option.
.Sp
\&\fIpathlist\fR should be one or more paths to a directory or jar file,
separated by your platform's path separator (usually \fB:\fR or
\&\fB;\fR).
.Sp
If this option is not intercepted at the wrapper level,
\&\fBgjdoc\fR currently fakes it by calling
\&\fBSystem.setProperty(\*(L"java.class.path\*(R",\fR \fIpathlist\fR\fB);\fR and
outputs a warning.
.IP "\fB\-bootclasspath\fR \fIpathlist\fR" 4
