edoc_extract(3erl) Erlang Module Definition edoc_extract(3erl)
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) :
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 environ-
ment 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(3erl) , header/5 .
header(Forms, Comments::[comment() (see module edoc)], File::filename(), Env::edoc_env(), Options::proplist()) -> {ok, Tags} | {error, Rea-
son}
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 infor-
mation. (Cf. edoc:read_comments/2 .)
See also: erl_recomment(3erl) , 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.
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)}
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.
See also: erl_recomment(3erl) , source/5 , edoc:read_comments/2 , edoc:read_source/2 .
source(Forms, Comments::[comment() (see module edoc)], File::filename(), Env::edoc_env(), Options::proplist()) -> {ModuleName, edoc_mod-
ule() (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 .)
See also: erl_recomment(3erl) , 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.
