Released Json-Type v0.11.1

Mon Apr  9 14:02:42 EEST 2018

Work done in the front-end program and only very minimally in the library:

* improve speed of processing long command line options by using Trie-Gen's
  version 0.6 new feature of generating unique prefix trie lookup functions;
* update the documenting text 'doc/gen-func.txt' to reflect Trie-Gen's first
  source code tarball release (no longer need to clone Trie-Gen's 'git' repo
  for to be able to use the program as meta-tool of Json-Type);
* fix bogus I/O error handling within API function 'json_file_is_shared_obj';

--------------------------------------------------------------------------------

Released Json-Type v0.11.0

Sun Feb 11 18:49:57 EET 2018

Work done both in the library and in the front-end program:

* found and fixed minor bug (#39) in the library (see BUGS file);
* removed obsoleted command line options `-q|--[no-]quote-control'; new options
  replace the deleted ones -- `-c|--[no-]escape-utf8' --, providing an extended
  and better functionality;
* added a few more useful command line options `-y|--[no-]empty-input' and
  `-p|--sigpipe-action=NAME';
* improved the information produced by command line option `--version';
* make 'json.so' a true shared library (build with `-shared') and runnable by
  itself (producing version numbers and build date time as before did);
* all compiled type libraries are by now runnable by themselves, printing out
  the version numbers of 'json.so' that generated them in the first place (see
  the newly added subsection 4.e of the README file);
* lots of refactoring of code both in the library and in the front-end program;
* extended the test suite with new test-cases for improved code coverage.

Note that the library version changed from '0.10.1' to '0.11.0'. This means that
all user's compiled type libraries must be rebuilt. (The newly added subsection
4.e of the README file puts in plain words this rule that was in place since the
inception of Json-Type).

--------------------------------------------------------------------------------

Released Json-Type v0.10.1

Tue Nov 14 17:18:21 EET 2017

Work done both in the library and in the front-end program:

* found and fixed a bug (#38) in the library (see the latest entry in BUGS);
* removed the CONFIG_PTR_* parameters in 'config.h' relating to non-standard
  pointer operations; also removed the library code under the control of these
  configuration parameters;
* adjusted the source code for it to be consumed cleanly by GCC 7.2.0 (that is
  build Json-Type with `-Wall -Wextra' getting no warnings);
* built and ran the front-end program and the library with GCC's 7.2.0 ASAN and,
  respectively, UBSAN instrumentation enabled: these instrumented binaries pass
  the entire test suite of Json-Type;
* several minor code corrections and clean-ups in the library, in the front-end
  program and also in the test suite.

Added a new documentation file 'doc/clang-build.txt' which describes briefly
patching the source tree (with the attached patch file 'doc/clang-build.patch')
for to be able to obtain a clean build from Clang 3.4 or newer.

--------------------------------------------------------------------------------

Released Json-Type v0.10.0

Sun 15 Oct 2017 02:59:19 PM EEST

Work done both in the library and in the front-end program:

* implemented surrogate pair escape parsing and generating;

* minor code clean-up.

--------------------------------------------------------------------------------

Released Json-Type v0.9.2

Mon 19 Jun 2017 11:46:06 AM EEST

Work done in the library:

* found and fixed a minor bug (#37) in "dict" expressions parser (see the
  latest entry in BUGS);
* simplified a bit the tokenizer of "dict" expression parser (function
  'json_type_ruler_dict_expr_next_token').

--------------------------------------------------------------------------------

Released Json-Type v0.9.1

Fri 16 Jun 2017 10:37:45 AM EEST

Work done almost only in the library:

* fix wrong wording defining "dict" expression constraints in doc/type-spec.txt;
* fix minor issues in the library code (no impact to the outside world).

--------------------------------------------------------------------------------

Released Json-Type v0.9.0

Tue 06 Jun 2017 04:50:33 PM EEST

Work done in the library:

* implementation and tests for "dict" expressions (for details see
  doc/type-spec.txt and doc/type-samples.txt);
* a few minute corrections (no impact to the outside world).

--------------------------------------------------------------------------------

Released Json-Type v0.8.1

Mon 08 May 2017 12:23:35 PM EEST

Work done both in the library and in the front-end program:

* new library API class and front-end class for JSON-escaping of UTF-8 text;
* new command line options `-S|--escape-json' and `-r|--trim-spaces' in the
  front-end program exposing the newly added functionality;
* reviewed the UTF-8 processing in the library and trimmed off the code a bit
  (also added and fixed bug #36).

--------------------------------------------------------------------------------

Released Json-Type v0.8.0

Mon 10 Apr 2017 11:45:10 PM EEST

Work done for the most part in the library:

* implementation and tests for basic "dict" type objects ("dict"s are not
  yet supported as elements of "list" type objects);
* re-balancing of attribute tries prior to generating the type def code of
  a given type library.

--------------------------------------------------------------------------------

Released Json-Type v0.7.5

Mon 20 Feb 2017 12:06:15 PM EET

Fixed yet another bugs (#33 and #34) in lib/json.c:json_validate_utf8 in the library.

Also fixed a few minor typos in 'doc/type-spec.txt' and 'doc/gen-func.txt'.

--------------------------------------------------------------------------------

Released Json-Type v0.7.4

Sun 18 Sep 2016 08:55:02 PM EEST

Fixed an embarrassing bug in the library (lib/json.c:json_validate_utf8):

* Invalid UTF8 string "\xf4\xbf\xbf\xbf" wasn't rejected as erroneous;
* Related invalid UTF8 strings "\xf4\xbf" and "\xf4\xbf\xbf" correctly rejected
  but with improper error position.

Also included two more documentation files:

* 'doc/gen-func.txt': accounts for the usage of Trie-Gen
  (http://www.nongnu.org/trie-gen/) as a meta-tool;
* 'doc/trie-impl.txt': describes to a certain extent the trie data structure
  and its algorithms implemented in the header file 'lib/trie-impl.h'.

--------------------------------------------------------------------------------

Initial announcement of Json-Type (v0.7.0)

Sun 12 Jun 2016 05:27:27 PM EEST

This is the initial announcement of Json-Type project:

  http://www.nongnu.org/json-type/

Json-Type is a fully-compliant RFC 7159 and ECMA 404 push parser -- validating
UTF8 as per the Unicode Standard 8.0.0 -- and an on-the-fly type checker of
JSON text. It has a two-tiered structure: the core of its functionality is
enclosed in a dynamic library, while the front-end, the main program assembles
the variety of use-cases of the library into a convenient and comprehensive
command line interface.

Json-Type was first and foremost designed for employing its main service --
the type checking of JSON texts -- in shell scripts that call in Web services
programmatically. The program and the library are able to handle gracefully,
securely and very efficiently such scenarios as when Web services are sending
back huge amounts of JSON data.

The type checker of Json-Type is kind of unconventional: it does not build
any kind of a DOM tree nor an AST of its JSON input prior to proceed with
type validation. Alternatively, the type checker runs alongside the parser,
obeying the very logic of the push-parsing itself: while consuming given
chunks of input text one at a time, it stops as soon as it is detecting a
type error occurrence in the input given.

The author of this software is Stefan Vargyas <stvar@yahoo.com>.
