Changelog History

Page 1

• v0.5.1 Changes

  🚀 To be released.

• v0.5.0 Changes

  🚀 Released on August 24, 2018.

  Language

  • The uri type has completly gone; use url instead. [#126, #281 by Jonghun Park]
  • Added [@numeric-constraints](docs/annotation.md#numeric-constraints) annotation to constraint the range of unboxed types' values. [#206, #271 by Seunghun Lee]

  📄 Docs target

  • Docs target became to support manual pages besides reference docs extracted from Nirum source codes. It scans all CommonMark (i.e., *.md) files and transforms them to HTML pages.
  • CommonMark in docstrings became to support table syntax extension.
  • CommonMark in docstrings became to have a limited subset of special attributes extension. It's only allowed to heading elements and only anchor identifiers are supported (e.g., {#header-id}).
  • style, header, and footer options were added. These options purpose to customize the look and feel of the result pages.
  • Fixed an incorrect processing of CommonMark thight list items: it had crashed when a thight list item contains blocks other than paragraphs.
  • Package's version became shown on the generated docs. [#297, #304 by Jeong Ukjae]
  • Added opengraphs option for OpenGraph objects on docs. [#283, #305 by GyuYong Jung]
  • Added syntax highlighting including Nirum. [#310, #311, #313, #324 by MinJune Kim]
  • Added anchor links to types. [#225, #321 by Park Hyunwoo]

  Python target

  • Python 3.7 support. [#298, #300 by Alan D.J. Synn]
  • Fixed a bug that an uncaught NameError raises (instead of following the standardized way to handle validation errors through on_error) when a serialized value of a mapping lacks "key" or "value" field and a type/union tag/service named key-error is defined in the same module at the same time. [#318 by Dongwook Kim]
  • Fixed a bug that an uncaught NameError raises (instead of following the standardized way to handle validation errors through on_error) when a serialized value of a bigint is not an integral decimal string and a type/union tag/service named value-error is defined in the same module at the same time. [#318 by Dongwook Kim]

  Et cetera

  • Dropped 32-bit Windows support.

• v0.4.2 Changes

  🚀 Released on Aug 24, 2018.

  Language

  • Fixed a bug that package.toml file had been failed to load when the system locale does not use UTF-8. It's now independent from the system locale settings. [#290, #322 by Seunghun Lee]

  Et cetera

  • The official Docker image repository was moved to nirumlang/nirum (from spoqa/nirum).

• v0.4.1 Changes

  🚀 Released on June 8, 2018.

  Et cetera

  • The official Docker images became to have netbase pacakage. See the related issue on Haskell Stack as well.

• v0.4.0 Changes

  🚀 Released on May 25, 2018.

  Language

  • Union tags became possible to have default keyword. It's useful for migrating a record type to a union type. [#13, #227]

  • Enum members and union tags became disallowed to shadow an other type name in a module. It's because in some target languages we compile both types and members/tags into objects that share the same namespace. In Python, both types and union tags are compiled into classes.

    For example, the following definitions had been allowed, but now became disallowed:

    unboxed foo (text);
    //      ^~~
    enum bar = foo | baz;
    //         ^~~
    

    record foo (text a);
    //     ^~~
    union bar = foo (text b) | baz (text c);
    //          ^~~
    

    This rule is applied even between a member/tag and its belonging enum/union type as well. The following definitions are disallowed:

    enum foo = foo | bar;
         ^~~   ^~~
    

    union bar = foo (text a) | bar (text b);
          ^~~                  ^~~
    

    If you already have used the same name for a type and a tag, you can avoid breaking backward compatibility of serialization by specifying a different behind name. For example, if you've had a definition like:

    enum foo = foo | bar;
    //   ^~~   ^~~
    

    It can be changed like the following:

    enum foo = foo-renamed/foo | bar;
    //         ^~~~~~~~~~~ ^~~
    

    [#254, #255]

  • Enum members and union tags became disallowed to shadow other enum members and union tags even if they belong to an other type. It's because in some target language we compile them into objects that share the same namespace, regardless of their belonging type.

    For example, the following definitions had been allowed, but now became disallowed:

    enum foo = bar | baz;
    //         ^~~
    enum qux = quux | bar;
    //                ^~~
    

    union foo = bar (text a) | baz (text b);
    //          ^~~
    enum qux = quux | bar;
    //                ^~~
    

    union foo = bar (text a) | baz (text b);
    //                         ^~~
    union qux = quux (text c) | baz (text d);
    //                          ^~~
    

    If you already have used the same name for members/tags of different enum/union types, you can avoid breaking backward compatibility of serialization by specifying a different behind name. For example, if you've had a definition like:

    enum foo = bar | baz;
    //         ^~~
    union qux = bar (text a) | quux (text b);
    //          ^~~
    

    It can be changed like the following:

    enum foo = bar-renamed/bar | baz;
    //         ^~~~~~~~~~~ ^~~
    union qux = bar (text a) | quux (text b);
    

    [#254, #255]

  • Fixed a compiler bug that an error message on name duplicates had referred to a wrong line/column number. [#255]

  • Added aliased import. It's handy to avoid a name shadowing. [#217, #258]

    import iso (country as iso-country);
    import types (country);
    

  • Added support for integer type annotation argument. [#178, #267]

    service foo-service (
        @bar(baz=1)
        int32 qux (int32 quux),
    );
    

  • Deprecated uri and url type is added. [#126, #277 by Jonghun Park]

  📄 Docs target

  • A new required configuration targets.docs.title was added. It's rendered in generated HTML documents' <title> element. [#253]

  • Docs now have a sidebar which contains table of contents. [#257]

  • Fixed a bug that a module-level docs hadn't been rendered. Now it's shown in the right below the module name. [#259]

  Python target

  • Generated Python packages became to have two [entry points] (a feature provided by setuptools):

    • nirum.modules: It maps Nirum modules to Python modules. Nirum module paths are normalized to avoid underscores and upper letters and use hyphens and lower letters instead, e.g., foo-bar.baz. The table works well with renames settings as well.
    • nirum.classes: It maps Nirum types (including services) to Python classes. Nirum type names are qualified and their leading module paths are also normalized (the same rule to nirum.modules applies here).

  • Generated deserializers became independent from nirum-python runtime library. [[#160], #272]

    • Error messages made during deserialization became more standardized. Every error now consists of two fields: one represents a path to the value having an error, and other one is a human-readable message.

      For example, suppose there's types like:

      record user (dob date);
      record user-group ([user] users);
      

      and the following payload for user-group type is given:

      [
        {"_type": "user", "dob": "2000-06-30"},
        {"_type": "user", "dob": "2000-13-32"}
      ]
      

      An error is reported with a path like [1].dob.

    • Added an optional on_error callback parameter to generated __nirum_deserialize__() methods.

      It has to be a callable which has two parameters (and no return value). An on_error callback is called every time any validation/parsing error happens during deserialization, and it can be called multiple times at a single call of __nirum_deserialize__().

      The callback function's first parameter takes a string referring a path to the value having an error (e.g., '.users[0].dob'). The second parameter takes an error message string (e.g., 'Expected a string of RFC 3339 date, but the date is invalid.').

      When it's omitted or None, a ValueError is raised with a multiline message that consists of all error messages made during deserialization, as it has been.

  • Fixed a bug that record/union deserializers refuses payloads without "_type" field. It is only for humans and can be omitted according to the [specification](./docs/serialization.md).

  • All integral types (int32, int64, and bigint) became represented as [numbers.Integral][python2-numbers-integral] instead of [int][python2-int].

    There's no change to Python 3.

  • The uri type became represented as [basestring][python2-basestring] instead of [unicode][python2-unicode] in Python 2, since URI (unlike IRI) is limited to a subset of ASCII character set.

    There's no change to Python 3.

  • Generated type constructors became to validate field value's range or format besides class checks: range checks for int32/int64, time zone (tzinfo) awareness check for datetime, and basic format check for uri.

  • Generated service methods became to have its own serialization and deserialization functions. Each method object now has these attributes:

    • __nirum_serialize_arguments__ takes the same keywords to the method parameters and serialize them into a mapping object (which can be directly translated to a JSON object). It can raise a TypeError or ValueError if any invalid values are passed.
    • __nirum_deserialize_arguments__ takes a mapping object returned by json.load()/json.loads() (and an optional on_error callable) and deserialize it into a mapping object of pairs from parameter's facial name string to its corresponding Python object.

    • __nirum_argument_serializers__ is a mapping object that keys are a string of method's parameter facial name and values are its serializer.

      A serializer function takes an argument value and returns its corresponding value which can be passed to json.dump()/json.dumps(). It can raise a TypeError or ValueError if an argument is invalid.

    • __nirum_argument_deserializers__ is a mapping object that keys are a string of method's parameter behind name and values are its deserializer.

      A deserializer function takes an argument value preprocessed by json.load()/json.loads() with an optional on_error callback, and returns its corresponding Python object.

    • __nirum_serialize_result__ takes a method's return value and serialize it into a corresponding value which can be passed to json.dump()/json.dumps().

      If the given value does not match to method's return type it raises TypeError, or ValueError if the value is invalid.

      This attribute is None if the method has no return type.

    • __nirum_deserialize_result__ takes a result value preprocessed by json.load()/json.loads() with an optional on_error callback, and deserialize it into its corresponding Python object.

      This attribute is None if the method has no return type.

    • __nirum_serialize_error__ takes a method's error object and serialize it into a corresponding value which can be passed to json.dump()/json.dumps().

      If the given error object does not match to method's return type it raises TypeError, or ValueError if the error object is invalid.

      This attribute is None if the method has no error type.

    • __nirum_deserialize_error__ takes an error value preprocessed by json.load()/json.loads() with an optional on_error callback, and deserialize it into its corresponding Python object.

      This attribute is None if the method has no error type.

  • Removed __nirum_get_inner_type__() class methods from generated unboxed type classes.

  • Removed __nirum_record_behind_name__ static fields and __nirum_field_types__() class methods from generated record type classes.

  • Removed __nirum_tag_names__, __nirum_union_behind_name__, and __nirum_field_names__ static fields from generated union type classes.

  • Removed __nirum_tag_types__ static fields from generated union tag classes.

  • Removed __nirum_schema_version__ static field from generated service classes.

  • Fixed a bug that generated service methods hadn't checked its arguments before its transport sends a payload. [#220]

  • Fixed a bug that field/parameter names that use a module name of the Python standard library cause runtime TypeErrors (due to name shadowing). Under the hood, all generated imports are now aliased with a name prefixed an underscore.

  • Added Python classifier metadata field. [#100, #269]

  Et cetera

  • The officially distributed executable binaries for Linux became dependent on glibc again.
  • The official Docker images became based on Debian ([minideb]) instead of Alpine Linux. It's because Alpine Linux doesn't provide GHC 8.2 as of March 2018.

• v0.3.0 Changes

  🚀 Released on February 18, 2018.

  Language

  • [Package](./docs/package.md) is now a new compilation unit of Nirum. Every Nirum package needs package.toml manifest file. [#83, #99]
  • Since a Nirum package can be compiled to more than one target languages, the nirum command became to have -t/--target required parameter. [#106, #111, #114]
  • Added -w/--watch mode. [#91, #104, #218]
  • Annotations became able to have multiple arguments and every parameter became necessary to having its name (keyword). [#178, #190, #197]
  • Service methods became able to omit their return types. [#179, #199 by Yang Chun Ung]
  • Added @error annotation to make a type to subclass an exception base class (e.g., [Exception][python-exception] in Python) when it's compiled to OO languages. [#38, #127]
  • Union tag docstrings in parentheses became allowed. [#153, #154]
  • Fixed a parser bug that a bare identifier (i.e., unquoted identifier) cannot start with a reserved keyword, e.g., types (type is reserved), enumeration (enum is reserved). [#184, #189]
  • Fixed a parser bug that import names had been disallowing to have a trailing comma or newlines. [#202]
  • Fixed the nirum command bug that it had always terminated with exit code 0 even when it errored. [#97, #108]

  📄 Docs target

  • A new target, docs is now available. To generate docs for a Nirum package, specify --target docs option to the nirum command. [#10, #113, #116, #125, #131, #152, #170, #223]

  Python target

  • Now supports Python 2.7 besides Python 3.4 or later. [#50, #85, #93, #117, nirum-python #22]
  • Now requires nirum-python 0.6.0 or later. [#119, #141, #146]
  • From now on, in order to compile a Nirum package to Python, package.toml manifest need [targets.python][targets.python] section and targets.python.name field. [#99]
  • Added targets.python.minimum_runtime option to specify the minimum version of nirum-python runtime library. [#118, #119]
  • Added targets.python.renames option to rename module names when they are compiled to a Python module. [#121]
  • More package metadata became configurable. [#100]
    • targets.python.description [#174 by Seunghun Lee]
    • targets.python.license [#180 by Seunghun Lee]

    • Generated constructors of service clients became to take a nirum.transport.Transport instance.
    • Followed renamed/moved import paths of the runtime classes (e.g., nirum.rpc.Service became to nirum.service.Service).
    • The way to avoid name collision between generated types and runtime classes is changed. The runtime library had provided alternative names like service_type for Service and generated imports had been like from nirum.rpc import service_type, but it's now from nirum.service import Service as service_type.
  • Record/union tag fields of an optional type can be omitted when the constructor is called. [#70, #165 by Seunghun Lee]
  • Generated tag classes became qualified under its union class (e.g., Shape.Rectangle instead of Rectangle). Deprecated the old style and it is going to be obsolete in the near future. [#68, #193]
  • Generated service clients became qualified under its service class (e.g., FooService.Client instead of FooService_Client). Deprecated the old style and it is going to be obsolete in the near future. [#167, #222].

  • Fixed a bug that a generated Python enum code had became broken when an enum type has a member named mro. [#185, #188]

  Et cetera

  • The officially distributed executable binaries for Linux became independent from glibc; instead statically linked to musl. #216
  • The Docker image now has nirum command in PATH. [#155]
