docb_gen Generate XML from EDoc comments in Erlang source code.

docb_gen contains functions for generating XML documentation source code according to the erlref or chapter DTD from EDoc comments in Erlang source code or an overview.edoc file, using EDoc.

 module(File) -> ok | {error, Reason} module(File, Options) -> ok | {error, Reason} Generate XML from EDoc comments in Erlang source code. File = string() Options = [Opt] Opt = {def,Defs} | {includes,Dirs} | {preprocess,Bool} | {sort_functions,Bool} Defs = [{atom(),string()}] Dirs = [string()] Bool = bool() Reason = badfile | {badopt,term()} | term()

Generates XML documentation source code according to the erlref DTD from EDoc comments File, using the EDoc application.

File is an Erlang source file, given with or without the .erl extension as Name.erl or Name. The resulting XML file is created in the current working directory and named Name.xml.

Options is a list of options, see below.

Returns ok if successful, and an error tuple otherwise.

 users_guide(File) -> ok | {error, Reason} users_guide(File, Options) -> ok | {error, Reason} Generate XML from EDoc comments in Erlang source code File -- see module/1,2 Options -- see module/1,2 Reason -- see module/1,2

Like module/1,2 but generates XML source code according to the chapter DTD from an overview.edoc or similar file.

The resulting file is named chapter.xml.
Options {def, [{Name,Text}]} Specifies EDoc macro definitions. See edoc:get_doc/2. {includes, [Dir]} Specifies directories where EDoc should search for include files. See edoc:read_source/2. {preprocess, true|false} Specifies if EDoc should read the source file via the Erlang preprocessor. Default is false. See edoc:read_source/2. {sort_functions, true|false} Specifies if the functions in the resulting XML file should be sorted alphabetically. Default is true.
Limitations

The mapping from the EDoc XHTML output to valid Erlang/OTP XML is not complete. An attempt has been made to cover the most commonly used XHTML constructs, but there will still be cases where XML generation fails or where the resulting XML is inadequate. This is especially true for users_guide/1,2.

Known limitations for some XHTML tags:

]]>

All attributes except the first href or name attribute are ignored.

A href attribute means the ]]> tag will be transformed to a ]]> or ]]> tag and an attempt is made to resolve the reference if necessary.

A name attribute means the ]]> tag will be transformed to a ]]> tag.

 , , 
]]>
      Cannot contain other tags in Erlang/OTP XML, content is
	converted to plain text.
      

      ]]>
      No corresponding Erlang/OTP XML tag, converted to plain
	text.
      

      ]]>
      No corresponding Erlang/OTP XML tag, converted to plain
	text.
      

      , 
, ...]]>
      There is no tag corresponding to a header in Erlang/OTP XML,
	so these are converted to plain text instead, with
	the exception of ]]> and
	]]> tags within overview.edoc, see
	part about "chapter DTD" below.
      

      ]]>
      There is no tag corresponding to superscript in Erlang/OTP
	XML, so this is converted to plain text within brackets "(..)".
      

      References
      The markers automatically inserted by EDoc at each heading
	and function will override the markers automatically inserted
	by DocBuilder, with the unfortunate result that the links in
	the left-hand frame of the User's Guide will not work, and
	also that cross referencing a function in a module the usual
	Erlang/OTP way
	"]]>" does
	not work. (But
	"]]>" does.)
      
    

    
erlref DTD

    
      Tables
      Tables are not allowed. The contents of a table is
	converted to text instead, each row corresponding to one line
	of text.
      
    

    
chapter DTD

    
      Sections
      Only two levels of sections. ]]>
	(equivalent to EDoc headings "== Heading ==") is
	interpreted as start of top-level section, or if there is no
	]]> tag, the entire document is made into
	one top-level section. ]]> (equivalent to
	EDoc sub-headings ("") is
	interpreted as start of second-level section.
      

      Tables
      Tables without borders are converted to text in the same
	manner as for the erlref DTD.
