EDoc documentation extraction.
EDoc documentation extraction.
Functions
file(File::filename(), Context, Env::edoc_env(), Options::proplist()) -> {ok, Tags} | {error, Reason}
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}
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}
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}
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)}
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() (see module edoc)}
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)}
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.)
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
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.
