MODULE SUMMARY

EDoc documentation extraction.

DESCRIPTION

EDoc documentation extraction.

DATA TYPES

edoc_env() = edoc_env() (see module edoc_lib)
filename() = filename() (see module file)
proplist() = property() (see module proplists)
syntaxTree() = syntaxTree() (see module erl_syntax)
t() = t1(): Some docs of t/0; Further docs of t/0. The same thing using -type: -type t() :: t1(). % Some docs of t/0; Further docs of t/0.

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 or the atom 'invalid_unicode'.

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.

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() (see module edoc)], 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() (see module edoc)}

Types:

ModuleName = atom()

[term()]

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

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

Types:

Forms = syntaxTree() | [syntaxTree()]

ModuleName = atom()

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.

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

Types:

Forms = syntaxTree() | [syntaxTree()]

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.)

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.
