edoc

Equivalent to application(Application, []).

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

See also: application/1.

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.

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

Equivalent to file(Name, []).

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.

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

Equivalent to get_doc(File, []).

Types

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.

Types

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

Equivalent to layout(Doc, []).

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.

Equivalent to read(File, []).

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.

Equivalent to read_comments(File, []).

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

Equivalent to read_source(File, []).

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(3), get_doc/2.

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.)
