# 1 Syntax_Tools Release Notes

This document describes the changes made to the Syntax_Tools application.

### 1.1 Syntax_Tools 1.7

#### Improvements and New Features

- Use the new erl_anno module.

  Own Id: OTP-12732

- The merl module has been added to the syntax_tools application. The Merl library is a simpler way to work with erl_syntax parse trees.

  Own Id: OTP-12769

### 1.2 Syntax_Tools 1.6.18

#### Fixed Bugs and Malfunctions

- Fix bad format of error in epp_dodger:parse_file/3

  Own Id: OTP-12406

### 1.3 Syntax_Tools 1.6.17

#### Fixed Bugs and Malfunctions

- Teach Maps to erl_syntax

  Affected functions:

  - erl_syntax:abstract/1
  - erl_syntax:concrete/1
  - erl_syntax:is_leaf/1
  - erl_syntax:is_literal/1

  Own Id: OTP-12265

### 1.4 Syntax_Tools 1.6.16

#### 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

### 1.5 Syntax_Tools 1.6.15

#### Fixed Bugs and Malfunctions

- Fix reverting map in syntax_tools

  There was a bug in erl_syntax when running e.g. erl_syntax:revert_forms, affecting maps. Instead of getting Key/Value you got Key/Key in the resulting abstract form.

  Own Id: OTP-11930

### 1.6 Syntax_Tools 1.6.14

#### 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

#### Improvements and New Features

- Add implementation of having erl_tidy print to screen instead of writing to the file provided. (Thanks to Aaron France)

  Own Id: OTP-11632

- Support Maps syntax in syntax_tools (Thanks to Anthony Ramine).

  Own Id: OTP-11663

### 1.7 Syntax_Tools 1.6.13

#### Fixed Bugs and Malfunctions

- In syntax_tools-1.6.12 (OTP R16B03) a bug was introduced which broke reverting of local implicit funs. Implicit funs were mistakenly thought to be using abstract terms for their name and arity. This has now been corrected. (Thanks to Anthony Ramine)

  Own Id: OTP-11576

#### Improvements and New Features

- The default encoding of Erlang files has been changed from ISO-8859-1 to UTF-8.

  The encoding of XML files has also been changed to UTF-8.

  Own Id: OTP-10907

### 1.8 Syntax_Tools 1.6.12

#### Fixed Bugs and Malfunctions

- Fix transformation of implicit funs in igor (Thanks to Anthony Ramine)

  Own Id: OTP-11506

### 1.9 Syntax_Tools 1.6.11

#### Improvements and New Features

- Miscellaneous updates due to Unicode support.

  Own Id: OTP-10820

### 1.10 Syntax_Tools 1.6.10

#### Improvements and New Features

- Support for Unicode has been implemented.

  Own Id: OTP-10302

### 1.11 Syntax_Tools 1.6.9

#### Fixed Bugs and Malfunctions

- Syntax Tools 1.6.9

  Minor bugfixes, spec annotations and documentation cleanup. Thanks to Richard Carlsson

  Own Id: OTP-10208

### 1.12 Syntax_Tools 1.6.8

#### Fixed Bugs and Malfunctions

- Minor suppressions and fixes of compilation warnings

  Own Id: OTP-10016

### 1.13 Syntax_Tools 1.6.7.2

#### Improvements and New Features

- Variables are now now allowed in 'fun M:F/A' as suggested by Richard O'Keefe in EEP-23.

  The representation of 'fun M:F/A' in the abstract format has been changed in an incompatible way. Tools that directly read or manipulate the abstract format (such as parse transforms) may need to be updated. The compiler can handle both the new and the old format (i.e. extracting the abstract format from a pre-R15 BEAM file and compiling it using compile:forms/1,2 will work). The syntax_tools application can also handle both formats.

  *** POTENTIAL INCOMPATIBILITY ***

  Own Id: OTP-9643

- Eliminate use of deprecated regexp module

  Own Id: OTP-9810

### 1.14 Syntax_Tools 1.6.7.1

#### Fixed Bugs and Malfunctions

- In a file containing declarations and comments without any empty lines between them, the recomment_forms() function would associate a multi-line comment with the declaration above it rather than the one following it. (Thanks to Richard Carlsson and Kostis Sagonas.)

  Own Id: OTP-9180

### 1.15 Syntax_Tools 1.6.7

#### Improvements and New Features

- Miscellaneous updates

  Own Id: OTP-8976

### 1.16 Syntax_Tools 1.6.6

#### Improvements and New Features

- Minor changes and clean-ups.

  Own Id: OTP-8709

### 1.17 Syntax_Tools 1.6.5

#### 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

### 1.18 Syntax_Tools 1.6.4

#### Improvements and New Features

- The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.
