NAME

DESCRIPTION

EDoc documentation extraction.

DATA TYPES

edoc_env() = edoc_lib:edoc_env():
filename() = file:filename():
proplist() = proplists:property():
syntaxTree() = erl_syntax:syntaxTree():

EXPORTS

file(File::filename(), Context, Env::edoc_env(), Options::proplist()) -> {ok, Tags} | {error, Reason}
 
Types:
Context = overview
 
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::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::[edoc: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(3erl), header/3, header/4.
source(File::filename(), Env::edoc_env(), Options::proplist()) -> {ModuleName, edoc:edoc_module()}
 
Types:
ModuleName = atom()
 
proplist() = [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:edoc_module()}
 
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/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.
See also: erl_recomment(3erl), source/5, edoc:read_comments/2, edoc:read_source/2.
source(Forms, Comments::[edoc:comment()], File::filename(), Env:: edoc_env(), Options::proplist()) -> {ModuleName, edoc:edoc_module()}
 
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
 
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.
