Correct the documentation of the error tuple returned by Yecc and Leex.

The new -dialyzer() attribute is used for suppressing Dialyzer warnings in generated code.

Own Id: OTP-12271

The line counter becomes invalid when rules with linewrap are used. This issue appears because the parsing FSM does not roll back the line counter after attempting such a rule.

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.

A bug causing Yecc to generate badly formed parsers when encountering very simple recursive rules has been fixed. (Thanks to Eric Pailleau.)

Own Id: OTP-11269

A bug where Unicode filenames combined with Latin-1 encoding could crash Yecc and Leex has been fixed.

Own Id: OTP-11286

Fix leex module`s inability to build unicode-aware lexers. Thanks to Pierre Fenoll.

Support for Unicode has been implemented.

Own Id: OTP-10302

The file esyntax.yrl has been removed.

Own Id: OTP-10660

Tuple funs (a two-element tuple with a module name and a function) are now officially deprecated and will be removed in R16. Use 'fun M:F/A' instead. To make you aware that your system uses tuple funs, the very first time a tuple fun is applied, a warning will be sent to the error logger.

Own Id: OTP-9649

Dialyzer warnings have been removed.

yecc: add warnings_as_errors option(Thanks to Tuncer ayaz)

Own Id: OTP-9376

Fix incorrect order of pseudo variables in yecc example

The example is for converting from infix to prefix. This change uses to correct ordering of the triplet. (Thanks to Garret Smith)

Own Id: OTP-9484

Implement or fix -Werror option

If -Werror is enabled and there are warnings no output file is written. Also make sure that error/warning reporting is consistent. (Thanks to Tuncer Ayaz)

Own Id: OTP-9536

XML files have been corrected.

Own Id: OTP-9550 Aux Id: OTP-9541

The formating of Yecc's error messages has been improved. (Thanks to Joe Armstrong.)

Own Id: OTP-8919

Running HiPE-compiled Yecc parsers no longer results in a function_clause error.

Own Id: OTP-8771

Yecc failed to report reduce/reduce conflicts where one of the reductions involved the root symbol. This bug has been fixed. (Thanks to Manolis Papadakis.)

Own Id: OTP-8483

A bug introduced in Parsetools 1.4.4 (R12B-2) has been fixed. (Thanks to Manolis Papadakis.)

Own Id: OTP-8486

Cleanups suggested by tidier and modernization of types and specs.

Own Id: OTP-8455

Leex no longer uses the deprecated regexp module. (Thanks to Robert Virding.).

Own Id: OTP-8231

A minor bug in leex(3) has been fixed.

Own Id: OTP-8197

Leex, a lexical analyzer generator for Erlang, has been added to Parsetools. This initial version should be considered experimental; it is known that there will be changes and additions. (Thanks to Robert Virding.).

Own Id: OTP-8013

The parsers generated by Yecc now report correct error lines when possible.

Own Id: OTP-7969

A bug in yeccpre.hrl introduced in R13A has been fixed.

Own Id: OTP-7945

Updated file headers.

Own Id: OTP-7798

The yecc grammar has been augmented with an optional header section. (Thanks to Richard Carlsson.)

Own Id: OTP-7292

The size of the code generated by Yecc has been reduced. The code is also faster.

Macros can now be used in actions.

Own Id: OTP-7224

tuple_size/1 and byte_size/1 have been substituted for size/1.

Own Id: OTP-7009

The size of the code generated by yecc has been reduced.

A note regarding the includefile option: although yecc can cope with includefiles based on some earlier yeccpre.hrl it is recommended for efficiency reasons to update includefiles as to follow the pattern in the latest yeccpre.hrl.

Own Id: OTP-6851

Minor Makefile changes.

Own Id: OTP-6689

A bug concerning precedence declarations of non-terminals "one level up" has been fixed in yecc.

Own Id: OTP-6362

The new functions file/1,2 take the role of the old functions yecc/2,3,4. The latter functions are no longer documented but are kept for backward compatibility.

More checks of the grammar file have been implemented. Examples are warnings for unused non-terminals and duplicated declarations.

Invalid pseudo variables are no longer replaced by '$undefined' but cause a failure.

Reserved words no longer need to be quoted when used as terminals or non-terminals.

When compiling the generated parser file errors and warnings concerning user code refer to the grammar file, not the parser file.

Yecc emits a warning if there are conflicts in the grammar. The new declaration Expect can be used to suppress this warning.

The new operator precedence declaration Nonassoc can be used to declare operators with no associativity.

Precedence can be given to more than one operator with one single operator precedence declaration.

The function parse_and_scan/1 in the default includefile accepts {Function, A} as well as {{M,F}, A} as tokenizer function. Exceptions in the tokenizer are never caught.

The functions yecc:file/1,2 can be accessed from the Erlang shell via the new functions c:y/1,2 in STDLIB.

A bug in Yecc that was introduced in R9B has been removed. Another bug concerning precedence declaration "one level up" has been fixed.

Own Id: OTP-5461

A bug in the file parsetools/include/yeccpre.hrl caused yecc:parse_and_scan/1 to always report a parse failure when the lexer reported end-of-file. This problem has been fixed.
