erl_syntax_lib:annotate_bindings/1,2 will now properly annotate named functions and their arguments.
Own Id: OTP-18380 Aux Id: PR-6523, GH-4733
The erl_syntax_lib:analyze_attribute/1 function would return {Name, {Name, Value}} instead of {Name, Value} (which is the documented return value).

Own Id: OTP-17894 Aux Id: PR-5509
Added support for configurable features as described in EEP-60. Features can be enabled/disabled during compilation with options (-enable-feature Feature, -disable-feature Feature and +{feature, Feature, enable|disable}) to erlc as well as with directives (-feature(Feature, enable|disable).) in the file. Similar options can be used to erl for enabling/disabling features allowed at runtime. The new maybe expression (EEP-49) is fully supported as the feature maybe_expr. The features support is documented in the reference manual.
Own Id: OTP-17988
The type spec of erl_syntax:function_type/2 has been fixed.
Own Id: OTP-17302 Aux Id: PR-4705

Own Id: OTP-17180
epp_dodger was unable to handle a parameterized macro in a function head.
Own Id: OTP-17064 Aux Id: GH-4445, PR-2964
All functions in erl_tidy in syntax_tools have now been deprecated and are scheduled for removal in OTP 24. Users who still need it can find it at https://github.com/richcarl/erl_tidy.
Own Id: OTP-17167 Aux Id: OTP-17046
In the syntax_tools application, the igor module and all functions in erl_tidy except file/2 have been deprecated.

Own Id: OTP-13725 Aux Id: ERL-151, PR-1071
merl_transform could get into an infinite loop when syntactically incorrect text was passed to a merl:qquote/2,3 call.
Own Id: OTP-13755
Improve types and specs in OTP documentation generated from Erlang source files.
Own Id: OTP-13720 Aux Id: ERL-120
The abstract data type in erl_syntax is augmented with types and function specifications.
The module erl_prettypr pretty prints types and function specification, and the output can be parsed.
The types of record fields are no longer ignored. As a consequence erl_syntax_lib:analyze_record_field/1 returns {Default, Type} instead of Default. The functions analyze_record_attribute, analyze_attribute, analyze_form, and analyze_forms in the erl_syntax_lib module are also affected by this incompatible change.
*** POTENTIAL INCOMPATIBILITY ***
Own Id: OTP-12863
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
Fix bad format of error in epp_dodger:parse_file/3
Own Id: OTP-12406
Teach Maps to erl_syntax
Affected functions:
Own Id: OTP-12265
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
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
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
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
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
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
Fix transformation of implicit funs in igor (Thanks to Anthony Ramine)
Own Id: OTP-11506
Miscellaneous updates due to Unicode support.
Own Id: OTP-10820
Support for Unicode has been implemented.
Own Id: OTP-10302
Syntax Tools 1.6.9
Minor bugfixes, spec annotations and documentation cleanup. Thanks to Richard Carlsson
Own Id: OTP-10208
Minor suppressions and fixes of compilation warnings
Own Id: OTP-10016
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
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
Miscellaneous updates
Own Id: OTP-8976
Minor changes and clean-ups.
Own Id: OTP-8709
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
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.
