fpdoc - The FPC Pascal unit documentation generator.
fpdoc --input=inputcommand [--output=output] [--format=fmt] [--descr=descriptionfile]
fpdoc scans a Free Pascal unit source file and generates documentation for it. The
documentation can be in various formats (currently HTML and LaTeX) It can read various
description files which contain the description for the various symbols found in the unit
You can invoke fpdoc with as the only required argument the 'input' and 'package'
arguments. It should at least contain the name of the unit file for which documentation
should be generated and the name of the package to which the unit belongs.
fpdoc has several options, most of them optional, defaults will be used in most cases.
This option tells fpdoc to generate a content file. A content file contains a list
of all the possible anchors (labels) in the generated documentation file, and can
be used to create cross-links in documentation for different units, using the
This option tells fpdoc for which CPU to generate documentation. This simply
defines the approriate CPU macros.
This option specifies the name of a description file descfile that contains the
actual documentation for the unit. This option can be given several times, for
several description files.
This option specifies the name of a directory with XML description files, named dir
This option can be given several times, for several description directories. This
option is equivalent to specifying all files in the directory with the --descr
This option tells fpdoc not to trim whitespace in the XML files. By default,
whitespace is trimmed from the input, which can have undesirable side-effects in
for instance PRE tags.
This option tells fpdoc not to generate any output, but just parse all input. This
can be used with the verbose option to check what errors remain in the
documentation, or what is still missing.
Specifies the format fmt in which the documentation will be generated. Currenly,
the following formats are known:
chm CHM with 8.3 conforming filenames, for windows mostly.
dxml Delphi compatible XML output.
htm HTML with 8.3 conforming filenames.
html HTML with long filenames.
ipf IPF output (OS/2 format, can be used with docview from fpGUI).
xhtml XHTML with long filesnames.
latex LaTex, which uses the fpc.sty style used by the Free Pascal documentation.
man man page output (unix manual pages, one page per identifier).
rtf RTF output.
txt Plain text output.
--help Show a command-line option summary.
By default, the documentation will include descriptions and listings of protected
fields and methods in classes or objects. This option changes this behaviour; if it
is specified, no documentation will be generated for these methods. Note that
public methods or properties that refer to these protected method will then have a
dangling (i.e. unavailable) link.
Adds an entry for an HTML search page at location link in the headers of the
generated HTML pages. There is no search page provided, this should be made and
provided by the user.
imports a content file impfile from another documentation set. This can be used to
resolve references to elements within this other documentation file;
This option tells fpdoc what input file should be used. The argument cmd can be
just a filename, but can also be a complete compiler command-line with options that
concern the scanning of the pascal source: defines, include files, syntax options,
as they would be specified to the free pascal compiler when compiling the file. If
a complete command is used, then it should be enclosed in single or double quotes,
so the shell will not break them in parts. It is possible to specify multiple
input commands; they will be treated one by one, and documentation will be
generated for each of them.
This option tells fpdoc to add all .pas and .pp files in the directory named cmd as
input files to the documenter. This is equivalend to specifying all files in the
directory with the --input command.
Sets the language for the output file. This will mainly set the strings used for
the headers in various parts of the documentation files (by default they're in
english). Currently, valid options are
Sets the extension to use for the LaTeX file to ext the default is .tex (with .
Switches on an internal latex syntax highlighter. This is not yet implemented. By
default, syntax highlighting is provided by the syntax package that comes with fpc.
This option tells fpdoc where to look for the translation files that can be used to
internationalize fpdoc's output.
This option tells fpdoc for which operating system to generate documentation. This
simply defines the approriate operating system macros.
This option tells fpdoc where the output file should be generated. How this option
is interpreted depends on the format that is used. For latex, name is interpreted
as the filename for the tex file. For all other formats, name is interpreted as the
directory where all documentation files will be written. The directory will be
created if it does not yet exist. Standard this equals the package name.
Specifies the package name. All units will be documented as part of packagename ,
which is also the default output filename or directory. Only documentation nodes
inside a package node with this name will be considered when documenting.
(Experimental) try to parse the implementation of a unit too, this can be used for
This option tells fpdoc to read all options from a project file. This is an XML
file, please see the documentation for more information about the format for this
By default, no documentation is generated for private methods or fields. This
option causes fpdoc to generate documentation for these methods as well.
By default, fpdoc is sparse with output. This tells fpdoc to generate some more
information about what it is doing.
If this option is specified, fpdoc will emit a warning if it does not find a
description node for an identifier it is documenting.
If this option is specified, fpdoc will write a fpdoc project file (to the
specified file name) that corresponds to the command-line options given.
