file(File, Context, Env, Opts) -> {ok, Tags} | {error, Reason}

Types

File = filename()

Context = edoc_tags:tag_flag()

Env = edoc:env()

Opts = proplist()

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/3. 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, Env, Opts) -> edoc:entry_data()

Types

File = filename()

Env = edoc:env()

Opts = proplist()

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

header(Forms, File, Env, Opts) -> edoc:entry_data()

Types

Forms = erl_syntax:forms()

File = filename()

Env = edoc:env()

Opts = proplist()

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, File, Env, Opts) -> edoc:entry_data()

Types

Forms = erl_syntax:forms()

Comments = [edoc:comment()]

File = filename()

Env = edoc:env()

Opts = proplist()

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, Env, Opts) -> R

Types

File = filename()

Env = edoc:env()

Opts = proplist()

R = {module(), edoc:edoc_module()} | {module(), edoc:edoc_module(), [edoc:entry()]}

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

source(Forms, File, Env, Opts) -> R

Types

Forms = erl_syntax:forms()

File = filename()

Env = edoc:env()

Opts = proplist()

R = {module(), edoc:edoc_module()} | {module(), edoc:edoc_module(), [edoc:entry()]}

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/3. 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, File, Env, Opts) -> R

Types

Forms = erl_syntax:forms()

Comments = [edoc:comment()]

File = filename()

Env = edoc:env()

Opts = proplist()

R = {module(), edoc:edoc_module()} | {module(), edoc:edoc_module(), [edoc:entry()]}

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, Context, Env, Opts) -> Tags

Types

Text = string()

Context = overview

Env = edoc:env()

Opts = proplist()

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/3.

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