# 1 EDoc Release Notes

This document describes the changes made to the EDoc application.

###
1.1 Edoc 1.1

####
Improvements and New Features

- Add option link_predefined_types that is used to create links to erlang predefined types. This is mainly to be used by erl_docgen when creating the Erlang/OTP documentation.

  Own Id: OTP-17743 Aux Id: PR-5292

###
1.2 Edoc 1.0.1

####
Fixed Bugs and Malfunctions

- Fix broken documentation link in edoc_extract:file/4.

  Own Id: OTP-17552 Aux Id: GH-5058

###
1.3 Edoc 1.0

####
Fixed Bugs and Malfunctions

- Fix so that the edoc_doclet option file_suffix also effects the links emitted into the module index.

  Own Id: OTP-17092

####
Improvements and New Features

- EDoc, the Erlang documentation engine, hits version 1.0 with this release, which means a few changes.

  EDoc is now capable of emitting EEP-48 doc chunks. This means that, with some configuration, community projects can now provide documentation for shell_docs the same way that OTP libraries did since OTP 23.0.

  The @spec and @type EDoc tags have been deprecated. These are not supported with the new chunk-generating doclet and layout. Moreover, previously when there was a redundant @spec tag and -spec attribute defined for the same function, the @spec tag would take precedence. Now, the -spec attribute takes precedence and is more important. The same is true for redundant @type tags and -type attributes. Warnings are now emitted when such redundant entries are found.

  The ?NO_APP macro in edoc_doclet.hrl has been deprecated. Use the atom no_app instead.

  See the Doc chunks chapter in the Edoc User's Guide for more details.

  *** POTENTIAL INCOMPATIBILITY ***

  Own Id: OTP-16949 Aux Id: PR-2803 OTP-17192

- Edoc has been updated to use -spec to document its own interface instead of @doc@ tags.

  Own Id: OTP-12058

###
1.19 Edoc 0.7.14

####
Fixed Bugs and Malfunctions

- The default encoding for Erlang source files is now UTF-8. As a temporary measure to ease the transition from the old default of Latin-1, if EDoc encounters byte sequences that are not valid UTF-8 sequences, EDoc will re-try in Latin-1 mode. This workaround will be removed in a future release.

  Own Id: OTP-12008

###
1.20 Edoc 0.7.13

####
Fixed Bugs and Malfunctions

- Application upgrade (appup) files are corrected for the following applications:

  asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl

  A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

  (Thanks to Tobias Schlager)

  Own Id: OTP-11744

###
1.21 Edoc 0.7.12.1

####
Improvements and New Features

- The encoding of the notes.xml file has been changed from latin1 to utf-8 to avoid future merge problems.

  Own Id: OTP-11310

###
1.22 Edoc 0.7.12

####
Fixed Bugs and Malfunctions

- EDoc sometimes failed to associate a comment with the preceding type declaration. This bug has been fixed. (Thanks to Serge Aleynikov for reporting the bug.)

  Own Id: OTP-10866

####
Improvements and New Features

- Miscellaneous updates due to Unicode support.

  Own Id: OTP-10820

###
1.23 Edoc 0.7.11

####
Improvements and New Features

- Since EDoc 0.7.7 (R14B02) separate values of union types can be annotated. However, the parser has hitherto chosen not to add the necessary parentheses due to backwards compatibility.

  From this release on code traversing the output of edoc_parser needs to take care of parentheses around separate values of union types. Examples of such code are layout modules and doclet modules.

  *** POTENTIAL INCOMPATIBILITY ***

  Own Id: OTP-10195

- Support for Unicode has been implemented.

  Own Id: OTP-10302

- Where necessary a comment stating encoding has been added to Erlang files. The comment is meant to be removed in Erlang/OTP R17B when UTF-8 becomes the default encoding.

  Own Id: OTP-10630

###
1.24 Edoc 0.7.10

####
Fixed Bugs and Malfunctions

- List behaviour callbacks in Edoc when using -callback attribute. (Thanks to Magnus Henoch.)

  Added special case for file names under Windows. (Thanks to Beads Land-Trujillo.)

  Own Id: OTP-10174

###
1.25 Edoc 0.7.9.1

####
Improvements and New Features

- Miscellaneous documentation build updates

  Own Id: OTP-9813

###
1.26 Edoc 0.7.9

####
Fixed Bugs and Malfunctions

- no_return is a new built-in type.

  Own Id: OTP-9350

- synchronized with edoc development version

  forgot to ensure that xmerl is found in path for include_lib to work

  fix -spec declaration that doesn't work in R13B04

  eliminate warnings about unused imports

  removed CVS-keywords from source files (Thanks to Richard Carlsson )

  Own Id: OTP-9463

- Add a proplist() type

  Recently I was adding specs to an API and found that there is no canonical proplist() type defined. (Thanks to Ryan Zezeski)

  Own Id: OTP-9499

- Removed some never-matching clauses reported by dialyzer Fix macro expansion in comments following Erlang types URI-escape bytes as two hex digits always (reported by Alfonso De Gregorio) Updated author e-mail Recognize some more URI schemas in wiki text, in particular https (Thanks to Richard Carlsson)

  Own Id: OTP-9590

###
1.27 Edoc 0.7.8

####
Fixed Bugs and Malfunctions

- Fix infinite loop for malformed edoc input

  When processing an edoc comment with ``` in it, if the comment ends without a matching ''' then an infinite loop occurs in the function edoc_wiki:strip_empty_lines/2. This change fixes that by adding a clause to return from the function upon the end of the comment input. This allows an error to be thrown to indicate the problem, which is the same behaviour as leaving either `` or ` unmatched. (Thanks to Taylor Venable)

  Own Id: OTP-9165

- Bugs concerning the option report_missing_types that was added in EDoc-0.7.7 have been corrected: the option was misspelled in the source, and local definitions as well as the function tags @private and @hidden were not handled correctly. (Thanks to Manolis Papadakis.)

  Own Id: OTP-9301

###
1.28 Edoc 0.7.7

####
Fixed Bugs and Malfunctions

- Add encoding when parsing Wiki text. EDoc used to fail on strings such as "äåö". (Thanks to Richard Carlsson.)

  Own Id: OTP-9109

####
Improvements and New Features

- It is now possible to use Erlang specifications and types in EDoc documentation. Erlang specifications and types will be used unless there is also a function specification (@spec) or a type alias (@type) with the same name. In the current implementation the placement of -spec matters: it should be placed where the @spec would otherwise have been placed.

  Not all Erlang types are included in the documentation, but only those exported by some export_type declaration or used by some documented Erlang specification (-spec).

  There is currently no support for overloaded Erlang specifications.

  The syntax definitions of EDoc have been augmented to cope with most of the Erlang types. (But we recommend that Erlang types should be used instead.)

  edoc:read_source() takes one new option, report_missing_types. edoc_layout:module() takes one new option, pretty_printer.

  Own Id: OTP-8525

- The edoc_lib module is meant to be private, but since it is referred to from other man pages it has been included in the OTP documentation. The modifications introduced in this ticket make all functions private except those referred to from other pages.

###
1.29 Edoc 0.7.6.8

  Own Id: OTP-8749

###
1.31 Edoc 0.7.6.6

####
Improvements and New Features

- The documentation is now possible to build in an open source environment after a number of bugs are fixed and some features are added in the documentation build process.

  - The arity calculation is updated.

  - The module prefix used in the function names for bif's are removed in the generated links so the links will look like "http://www.erlang.org/doc/man/erlang.html#append_element-2" instead of "http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".

  - Enhanced the menu positioning in the html documentation when a new page is loaded.

  - A number of corrections in the generation of man pages (thanks to Sergei Golovan)

  - The legal notice is taken from the xml book file so OTP's build process can be used for non OTP applications.

  Own Id: OTP-8343

###
1.32 Edoc 0.7.6.5

####
Improvements and New Features

  Own Id: OTP-6457

####
Improvements and New Features

  - New, built-in @version macro.

  - Added recognition of "TODO:" as a wiki equivalent for @todo tags.
  - Added documentation about overview pages.
