NAME

       edoc - EDoc - the Erlang program documentation generator.

DESCRIPTION

       EDoc - the Erlang program documentation generator.

       This module provides the main user interface to EDoc.

         * EDoc User Manual

         * Running EDoc

DATA TYPES

         comment() = {Line, Column, Indentation, Text}:

           * Line = integer()

           * Column = integer()

           * Indentation = integer()

           * Text = [string()]

         edoc_module():

           The  EDoc documentation data for a module, expressed as an XML document in XMerL format. See the file
           edoc.dtd for details.

         filename() = file:filename():

         proplist() = [term()]:

         syntaxTree() = erl_syntax:syntaxTree():

EXPORTS

       application(Application::atom()) -> ok

              Equivalent to application(Application, []).

       application(Application::atom(), Options::proplist()) -> ok

              Run EDoc on an application in its default app-directory. See application/3 for details.

              See also: application/1.

       application(Application::atom(), Dir::filename(), Options::proplist()) -> ok

              Run EDoc on an application located in the specified directory. Tries to automatically set up  good
              defaults. Unless the user specifies otherwise:

                * The  doc  subdirectory  will  be  used  as  the  target directory, if it exists; otherwise the
                  application directory is used.

                * The source code is assumed to be located in the src subdirectory, if it exists,  or  otherwise
                  in the application directory itself.

                * The subpackages option is turned on. All found source files will be processed.

                * The  include  subdirectory  is  automatically  added  to  the include path. (Only important if
                  preprocessing is turned on.)

              See run/2 for details, including options.

              See also: application/2.

       file(Name::filename()) -> ok

              This function is deprecated: See file/2 for details.

              Equivalent to file(Name, []).

       file(Name::filename(), Options::proplist()) -> ok

              This function is deprecated: This is part of the old interface to EDoc  and  is  mainly  kept  for
              backwards  compatibility.  The  preferred  way  of  generating documentation is through one of the
              functions application/2 and files/2.

              Reads a source code file and outputs formatted documentation to a corresponding file.

              Options:

                {dir, filename()}:
                  Specifies the output directory for the created file. (By default, the output is written to the
                  directory of the source file.)

                {source_suffix, string()}:
                  Specifies the expected suffix of the input file. The default value is ".erl".

                {file_suffix, string()}:
                  Specifies the suffix for the created file. The default value is ".html".

              See get_doc/2 and layout/2 for further options.

              For running EDoc from a Makefile or similar, see edoc_run:file/1.

              See also: read/2.

       files(Files::[filename()]) -> ok

       files(Files::[filename()], Options::proplist()) -> ok

              Runs EDoc on a given set of source files. See run/2 for details, including options.

       get_doc(File::filename()) -> {ModuleName, edoc_module()}

              Equivalent to get_doc(File, []).

       get_doc(File::filename(), Options::proplist()) -> {ModuleName, edoc_module()}

              Types:

                 ModuleName = atom()

              Reads  a  source  code file and extracts EDoc documentation data. Note that without an environment
              parameter (see get_doc/3), hypertext links may not be correct.

              Options:

                {def, Macros}:

                  * Macros = Macro | [Macro]

                  * Macro = {Name::atom(), Text::string()}

                  Specifies a set of EDoc macro definitions. See Inline macro expansion for details.

                {hidden, boolean()}:
                  If the value is true, documentation of hidden functions will also  be  included.  The  default
                  value is false.

                {private, boolean()}:
                  If  the  value  is true, documentation of private functions will also be included. The default
                  value is false.

                {todo, boolean()}:
                  If the value is true, To-Do notes written using @todo or @TODO tags will be  included  in  the
                  documentation. The default value is false.

              See read_source/2, read_comments/2 and edoc_lib:get_doc_env/3 for further options.

              See also: get_doc/3, layout/2, read/2, run/2, edoc_extract:source/5.

       get_doc(File::filename(), Env::edoc_lib:edoc_env(), Options::proplist()) -> {ModuleName, edoc_module()}

              Types:

                 ModuleName = atom()

              Like  get_doc/2,  but  for  a  given  environment  parameter.  Env  is  an  environment created by
              edoc_lib:get_doc_env/3.

       layout(Doc::edoc_module()) -> string()

              Equivalent to layout(Doc, []).

       layout(Doc::edoc_module(), Options::proplist()) -> string()

              Transforms EDoc module documentation data to text. The default layout creates an HTML document.

              Options:

                {layout, Module::atom()}:
                  Specifies a callback module to be used for formatting.  The  module  must  export  a  function
                  module(Doc, Options). The default callback module is edoc_layout; see edoc_layout:module/2 for
                  layout-specific options.

              See also: file/2, layout/1, read/2, run/2.

       read(File::filename()) -> string()

              Equivalent to read(File, []).

       read(File::filename(), Options::proplist()) -> string()

              Reads and processes a source file and returns the resulting EDoc-text as a string.  See  get_doc/2
              and layout/2 for options.

              See also: file/2.

       read_comments(File) -> [comment()]

              Equivalent to read_comments(File, []).

       read_comments(File::filename(), Options::proplist()) -> [comment()]

              Extracts  comments  from  an  Erlang  source  code file. See the module erl_comment_scan(3erl) for
              details on the representation of comments. Currently, no options are avaliable.

       read_source(Name::File) -> [syntaxTree()]

              Equivalent to read_source(File, []).

       read_source(File::filename(), Options::proplist()) -> [syntaxTree()]

              Reads an Erlang source file and returns the list of "source code form" syntax trees.

              Options:

                {preprocess, boolean()}:
                  If the value is true, the source file will be read via  the  Erlang  preprocessor  (epp).  The
                  default value is false. no_preprocess is an alias for {preprocess, false}.

                  Normally,  preprocessing  is not necessary for EDoc to work, but if a file contains too exotic
                  definitions or uses of macros, it will not be possible to read it without preprocessing. Note:
                  comments in included files will not be available to EDoc, even with this option enabled.

                {includes, Path::[string()]}:
                  Specifies a list of directory names to be searched for include files, if the preprocess option
                  is turned on. Also used with the @headerfile tag. The default value is  the  empty  list.  The
                  directory of the source file is always automatically appended to the search path.

                {macros, [{atom(), term()}]}:
                  Specifies  a  list  of  pre-defined  Erlang  preprocessor (epp) macro definitions, used if the
                  preprocess option is turned on. The default value is the empty list.

                {report_missing_types, boolean()}:
                  If the value is true, warnings are issued for missing  types.  The  default  value  is  false.
                  no_report_missing_types is an alias for {report_missing_types, false}.

              See also: erl_syntax(3erl), get_doc/2.

       run(Files::[filename()], Options::proplist()) -> ok

              Runs  EDoc  on  a  given  set  of  source  files.  Note  that the doclet plugin module has its own
              particular options; see the doclet option below.

              Also see layout/2 for layout-related options, and get_doc/2 for options related to reading  source
              files.

              Options:

                {app_default, string()}:
                  Specifies the default base URI for unknown applications.

                {application, App::atom()}:
                  Specifies  that the generated documentation describes the application App. This mainly affects
                  generated references.

                {dir, filename()}:
                  Specifies the target directory for the generated documentation.

                {doc_path, [string()]}:
                  Specifies a list of URI:s pointing to directories that contain  EDoc-generated  documentation.
                  URI  without a scheme:// part are taken as relative to file://. (Note that such paths must use
                  / as separator, regardless of the host operating system.)

                {doclet, Module::atom()}:
                  Specifies a callback module to be used for creating the documentation. The module must  export
                  a function run(Cmd, Ctxt). The default doclet module is edoc_doclet; see edoc_doclet:run/2 for
                  doclet-specific options.

                {file_suffix, string()}:
                  Specifies the suffix used for output files. The default value is ".html". Note that this  also
                  affects generated references.

                {new, boolean()}:
                  If  the value is true, any existing edoc-info file in the target directory will be ignored and
                  overwritten. The default value is false.

                {source_path, [filename()]}:
                  Specifies a list of file system paths used to locate the source code for packages.

                {source_suffix, string()}:
                  Specifies the expected suffix of input files. The default value is ".erl".

                {subpackages, boolean()}:
                  If the value is true, all subpackages of specified packages  will  also  be  included  in  the
                  documentation.  The  default  value  is  false.  no_subpackages  is an alias for {subpackages,
                  false}.

                  Subpackage source  files  are  found  by  recursively  searching  for  source  code  files  in
                  subdirectories  of  the known source code root directories. (Also see the source_path option.)
                  Directory names must begin with a lowercase letter and contain  only  alphanumeric  characters
                  and  underscore,  or  they will be ignored. (For example, a subdirectory named test-files will
                  not be searched.)
