NAME
edoc_extract - EDoc documentation extraction.

DESCRIPTION

EDoc documentation extraction.

DATA TYPES

    edoc_env() = edoc_env() (see module edoc_lib) :

    filename() = filename() (see module file) :

EXPORTS

file(File::filename(), Context, Env::edoc_env(), Options::proplist()) -> {ok, Tags} | {error, Reason}

    Types
        Context = overview | package
        Tags = [term()]
        Reason = term()

    Reads a text file and returns the list of tags in the file. Any lines of text before the first tag are ignored. Env is an environment created by edoc_lib:get_doc_env/4 . Upon error, Reason is an atom returned from the call to file:read_file/1 .

    See text/4 for options.

header(File::filename(), Env::edoc_env(), Options::proplist()) -> {ok, Tags} | {error, Reason}

    Types
        Tags = [term()]
        Reason = term()

    Similar to header/5 , but reads the syntax tree and the comments from the specified file.

    See also: header/4 , edoc:read_comments/2 , edoc:read_source/2 .

header(Forms, File::filename(), Env::edoc_env(), Options::proplist()) -> {ok, Tags} | {error, Reason}

    Types
        Forms = syntaxTree() | [syntaxTree()]
        Tags = [term()]
        Reason = term()

    Extracts EDoc documentation from commented header file syntax trees. Similar to source/5 , but ignores any documentation that occurs before a module declaration or a function definition. (Warning messages are printed if content may be ignored.) Env is assumed to already be set up with a suitable module context.

    See also: erl_recomment(3) , header/5 .

header(Forms, Comments::[comment()], File::filename(), Env::edoc_env(), Options::proplist()) -> {ok, Tags} | {error, Reason}

    Types
        Forms = syntaxTree() | [syntaxTree()]
        Tags = [term()]
        Reason = term()

    Similar to header/4 , but first inserts the given comments in the syntax trees. The syntax trees must contain valid position information. (Cf. edoc:read_comments/2 .)

    See also: erl_recomment(3) , header/3 , header/4 .

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

    Types
        ModuleName = atom()
        [term()]

    Like source/5 , but reads the syntax tree and the comments from the specified file.

    See also: source/4 , edoc:read_comments/2 , edoc:read_source/2 .

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

    Types
        Forms = syntaxTree() | [syntaxTree()]
        ModuleName = atom()
        edoc_module() (see module edoc)

    Extracts EDoc documentation from commented source code syntax trees. The given Forms must be a single syntax tree of type form_list , or a list of syntax trees representing "program forms" (cf. edoc:read_source/2 . Env is an environment created by edoc_lib:get_doc_env/4 . The File argument is used for error reporting and output file name generation only.

    See edoc:get_doc/2 for descriptions of the def , hidden , private , and todo options.

    See also: erl_recomment(3) , source/5 , edoc:read_comments/2 , edoc:read_source/2 .

source(Forms, Comments::[comment()], File::filename(), Env::edoc_env(), Options::proplist()) -> {ModuleName, edoc_module()}

    Types
        Forms = syntaxTree() | [syntaxTree()]
        {Line, Column, Indentation, Text}
        Line = integer()
        Column = integer()
        Indentation = integer()
        Text = [string()]
        ModuleName = atom()

    Like source/4 , but first inserts the given comments in the syntax trees. The syntax trees must contain valid position information. (Cf. edoc:read_comments/2 .)

    See also: erl_recomment(3) , source/3 , source/4 , edoc:read_comments/2 , edoc:read_source/2 .

text(Text::string(), Context, Env::edoc_env(), Options::proplist()) -> Tags

    Types
        Context = overview | package
        Tags = [term()]

    Returns the list of tags in the text. Any lines of text before the first tag are ignored. Env is an environment created by edoc_lib:get_doc_env/4 .

    See source/4 for a description of the def option.
