+Metadata-Version: 1.1
+Name: py-ubjson
+Version: 0.8.5
+Summary: Universal Binary JSON encoder/decoder
+Home-page: https://github.com/Iotic-Labs/py-ubjson
+Author: Iotic Labs Ltd
+Author-email: vilnis.termanis at iotic-labs.com
+License: Apache License 2.0
+Description: Overview
+ ========
+
+ This is a Python v3.2+ (and 2.7+) `Universal Binary
+ JSON <http://ubjson.org>`__ encoder/decoder based on the
+ `draft-12 <UBJSON-Specification.md>`__ specification.
+
+ Installing / packaging
+ ======================
+
+ .. code:: shell
+
+ # To get from PyPI
+ pip3 install py-ubjson
+
+ # To only build extension modules inline (e.g. in repository)
+ python3 setup.py build_ext -i
+
+ # To build & install globally
+ python3 setup.py install
+
+ # To skip building of extensions when installing (or building)
+ PYUBJSON_NO_EXTENSION=1 python3 setup.py install
+
+ **Notes**
+
+ - The (`cython <http://cython.org>`__-generated) extension modules are
+ not required but provide a significant speed boost.
+ - The above can also be run with v2.7+
+ - PyPI releases are signed with the `Iotic Labs Software release
+ signing key <https://iotic-labs.com/iotic-labs.com.asc>`__
+ - If any *.py* or *.pxd* has been modified, *cython*\ generate.sh\_ has
+ to be run first
+ - At run time, one can check whether compiled version is in use via the
+ *ubjson.EXTENSION*\ ENABLED\_ boolean
+
+ Usage
+ =====
+
+ It's meant to behave very much like Python's built-in `JSON
+ module <https://docs.python.org/3/library/json.html>`__, e.g.:
+
+ .. code:: python
+
+ import ubjson
+
+ encoded = ubjson.dumpb({u'a': 1})
+
+ decoded = ubjson.loadb(encoded)
+
+ **Note**: Only unicode strings in Python 2 will be encoded as strings,
+ plain *str* will be encoded as a byte array.
+
+ Documentation
+ =============
+
+ .. code:: python
+
+ import ubsjon
+ help(ubjson.dump)
+ help(ubjson.load)
+
+ Command-line utility
+ ====================
+
+ This converts between JSON and UBJSON formats:
+
+ .. code:: shell
+
+ python3 -mubjson
+ USAGE: ubjson (fromjson|tojson) (INFILE|-) [OUTFILE]
+
+ Tests
+ =====
+
+ Static
+ ------
+
+ This library has been checked using
+ `flake8 <https://pypi.python.org/pypi/flake8>`__ and
+ `pylint <http://www.pylint.org>`__, using a modified configuration - see
+ *pylint.rc* and *flake8.cfg*.
+
+ Unit
+ ----
+
+ .. code:: shell
+
+ ./coverage_test.sh
+
+ **Note**: This requires
+ `coverage <https://pypi.python.org/pypi/coverage>`__.
+
+ Limitations
+ ===========
+
+ - The **No-Op** type is not supported. (This should arguably be a
+ protocol-level rather than serialisation-level option.)
+ - Strongly-typed containers are only supported by the decoder (apart
+ from for **bytes**/**bytearray**).
+ - Encoder/decoder extensions are not supported at this time.
+ - cython optimizations could be improved.
+
+ Why?
+ ====
+
+ The only existing implementation I was aware of at the time of writing
+ (`simpleubjson <https://github.com/brainwater/simpleubjson>`__) had the
+ following limitations:
+
+ - Does not support efficient binary encoding
+ - Only supports draft-9
+ - Only supports individual Python types rather than anything
+ implementing an interface (e.g. *Mapping*)
+ - Does not decode nested arrays or objects in expected form
+ - Lacks C extension speed-up

+# <a name="introduction"/>Introduction
+For the official, most up-to-date, more verbose specification (with discussion and examples) of Universal Binary JSON please visit [ubjson.org](http://ubjson.org). Since at the time of writing (6th August 2015) neither said website nor the [community workspace git repository](https://github.com/thebuzzmedia/universal-binary-json) indicated what version the specification applies to, I made the decision to produce this minimal document to act as a reference in case the specification on ubj [...]

+
+
+# <a name="draft12"/>Draft 12 specification
+
+
+## <a name="data_format"/>Data Format
+
+A single construct with two optional segments (length and data) is used for all types:
+```
+[type, 1 byte char]([integer numeric length])([data])
+```
+Each element in the tuple is defined as:
+- **type** - A 1 byte ASCII char (**_Marker_**) used to indicate the type of the data following it.
+
+- **length** (_optional_) - A positive, integer numeric type (uint8, int16, int32, int64) specifying the length of the following data payload.
+
+- **data** (_optional_) - A run of bytes representing the actual binary data for this type of value.
+
+### Notes
+- Some values are simple enough that just writing the 1 byte ASCII marker into the stream is enough to represent the value (e.g. null) while others have a type that is specific enough that no length is needed as the length is implied by the type (e.g. int32) while others still require both a type and a length to communicate their value (e.g. string). Additionally some values (e.g. array) have additional (_optional_) parameters to improve decoding efficiency and/or to reduce size of the e [...]
+
+- The UBJSON specification requires that all numeric values be written in Big-Endian order.
+
+- To store binary data, use a [strongly-typed](#container_optimized) array of uint8 values.
+
+- _application/ubjson_ should be used as the mime type
+
+- _.ubj_ should be used a the file extension when storing UBJSON-encoded data is saved to a file

+
+## <a name="value_types"/>Value Types
+
+### <a name="value_null"/>Null
+The null value in is equivalent to the null value from the JSON specification.
+
+#### Example
+In JSON:
+```json
+{
+ "passcode": null
+}
+```
+
+In UBJSON (using block-notation):
+```
+[{]
+ [i][8][passcode][Z]
+[}]
+```
+
+---
+### <a name="value_noop"/>No-Op
+There is no equivalent to no-op value in the original JSON specification. When decoding, No-Op values should be skipped. Also, they can only occur as elements of a container.
+
+---
+### <a name="value_bool"/>Boolean
+A boolean type is is equivalent to the boolean value from the JSON specification.
+
+#### Example
+In JSON:
+```json
+{
+ "authorized": true,
+ "verified": false
+}
+```
+
+In UBJSON (using block-notation):
+```
+[{]
+ [i][10][authorized][T]
+ [i][8][verified][F]
+[}]
+```
+
+---
+### <a name="value_numeric"/>Numeric
+Unlike in JSON whith has a single _Number_ type (used for both integers and floating point numbers), UBJSON defines multiple types for integers. The minimum/maximum of values (inclusive) for each integer type are as follows:
+
+Type | Signed | Minimum | Maximum
+---|---|---|---
+int8 | Yes | -128 | 127
+uint8 | No | 0 | 255
+int16 | Yes | -32,768 | 32,767
+int32 | Yes | -2,147,483,648 | 2,147,483,647

+
+**Notes**:
+- Numeric values of infinity (and NaN) are to be encoded as a [null](#value_null) in all cases
+- It is advisable to use the smallest applicable type when encoding a number.
+
+#### Integer
+All integer types are written in Big-Endian order.
+
+#### Float
+- float32 values are written in [IEEE 754 single precision floating point format](http://en.wikipedia.org/wiki/IEEE_754-1985), which has the following structure:
+ - Bit 31 (1 bit) - sign
+ - Bit 30-23 (8 bits) - exponent
+ - Bit 22-0 (23 bits) - fraction (significant)
+
+- float64 values are written in [IEEE 754 double precision floating point format](http://en.wikipedia.org/wiki/IEEE_754-1985), which has the following structure:
+ - Bit 63 (1 bit) - sign
+ - Bit 62-52 (11 bits) - exponent
+ - Bit 51-0 (52 bits) - fraction (significant)
+
+#### High-Precision
+These are encoded as a string and thus are only limited by the maximum string size. Values **must** be written out in accordance with the original [JSON number type specification](http://json.org). Infinity (and NaN) are to be encoded as a [null](#value_null) value.
+
+#### Examples
+Numeric values in JSON:
+```json
+{
+ "int8": 16,
+ "uint8": 255,
+ "int16": 32767,
+ "int32": 2147483647,
+ "int64": 9223372036854775807,
+ "float32": 3.14,
+ "float64": 113243.7863123,
+ "huge1": "3.14159265358979323846",
+ "huge2": "-1.93+E190",
+ "huge3": "719..."
+}
+```
+
+In UBJSON (using block-notation):
+```
+[{]
+ [i][4][int8][i][16]
+ [i][5][uint8][U][255]
+ [i][5][int16][I]32767]
+ [i][5][int32][l][2147483647]
+ [i][5][int64][L][9223372036854775807]
+ [i][7][float32][d][3.14]
+ [i][7][float64][D][113243.7863123]
+ [i][5][huge1][H][i][22][3.14159265358979323846]
+ [i][5][huge2][H][i][10][-1.93+E190]
+ [i][5][huge3][H][U][200][719...]
+[}]
+```
+
+---
+### <a name="value_char"/>Char
+The char type in UBJSON is an unsigned byte meant to represent a single printable ASCII character (decimal values 0-127). It **must not** have a decimal value larger than 127. It is functionally identical to the uint8 type, but semantically is meant to represent a character and not a numeric value.
+
+#### Example
+Char values in JSON:
+```json
+{
+ "rolecode": "a",
+ "delim": ";",
+}
+```
+
+UBJSON (using block-notation):
+```
+[{]
+ [i][8][rolecode][C][a]
+ [i][5][delim][C][;]
+[}]
+```
+
+---
+### <a name="value_string"/>String
+The string type in UBJSON is equivalent to the string type from the JSON specification apart from that the UBJSON string value **requires** UTF-8 encoding.
+
+#### Example
+String values in JSON:
+```json
+{
+ "username": "rkalla",
+ "imagedata": "...huge string payload..."
+}
+```
+
+UBJSON (using block-notation):
+```
+[{]
+ [i][8][username][S][i][5][rkalla]
+ [i][9][imagedata][S][l][2097152][...huge string payload...]
+[}]
+```
+
+
+## <a name="container_types"/>Container types
+See also [optimized format](#container_optimized) below.
+
+### <a name="container_array"/>Array
+The array type in UBJSON is equivalent to the array type from the JSON specification.
+
+#### Example
+Array in JSON:
+```json
+[
+ null,
+ true,
+ false,
+ 4782345193,
+ 153.132,
+ "ham"
+]
+```
+
+UBJSON (using block-notation):
+```
+[[]
+ [Z]
+ [T]
+ [F]
+ [l][4782345193]
+ [d][153.132]
+ [S][i][3][ham]
+[]]
+```
+
+---
+### <a name="container_object"/>Object
+The object type in UBJSON is equivalent to the object type from the JSON specification. Since value names can only be strings, the *S* (string) marker **must not** be included since it is redundant.
+
+#### Example
+
+Object in JSON:
+```json
+{
+ "post": {
+ "id": 1137,
+ "author": "rkalla",
+ "timestamp": 1364482090592,
+ "body": "I totally agree!"
+ }
+}
+```
+
+UBJSON (using block-notation):
+```
+[{]
+ [i][4][post][{]
+ [i][2][id][I][1137]
+ [i][6][author][S][i][5][rkalla]
+ [i][9][timestamp][L][1364482090592]
+ [i][4][body][S][i][16][I totally agree!]
+ [}]
+[}]
+```
+
+## <a name="container_optimized"/>Optimized Format
+Both container types support optional parameters that can help optimize the container for better parsing performance and smaller size.
+
+### Type - *$*
+When a _type_ is specified, all value types stored in the container (either array or object) are considered to be of that singular _type_ and as a result, _type_ markers are omitted for each value within the container. This can be thought of providing the ability to create a strongly typed container in UBJSON.
+- If a _type_ is specified, it **must** be done so before a _count_.
+- If a _type_ is specified, a _count_ **must** be specified as well. (Otherwise it is impossible to tell when a container is ending, e.g. did you just parse *]* or the int8 value of 93?)
+
+#### Example (string type):
+```
+[$][S]
+```
+
+---
+### Count - *\#*
+When a _count_ is specified, the parser is able to know ahead of time how many child elements will be parsed. This allows the parser to pre-size any internal construct used for parsing, verify that the promised number of child values were found and avoid scanning for any terminating bytes while parsing.
+- A _count_ can be specified without a type.
+
+#### Example (count of 64):
+```
+[#][i][64]
+```
+
+### Additional rules
+- A _count_ **must** be >= 0.
+- A _count_ can be specified by itself.
+- If a _count_ is specified the container **must not** specify an end-marker.
+- A container that specifies a _count_ **must** contain the specified number of child elements.
+- If a _type_ is specified, it **must** be done so before count.
+- If a _type_ is specified, a _count_ **must** also be specified. A _type_ cannot be specified by itself.
+- A container that specifies a _type_ **must not** contain any additional _type_ markers for any contained value.
+
+---
+### Array Examples
+Optimized with count
+```
+[[][#][i][5] // An array of 5 elements.
+ [d][29.97]
+ [d][31.13]
+ [d][67.0]
+ [d][2.113]
+ [d][23.8889]
+// No end marker since a count was specified.
+```
+Optimized with type & count
+```
+[[][$][d][#][i][5] // An array of 5 float32 elements.
+ [29.97] // Value type is known, so type markers are omitted.
+ [31.13]
+ [67.0]
+ [2.113]
+ [23.8889]
+// No end marker since a count was specified.
+```
+
+---
+### Object Examples
+Optimized with count
+```
+[{][#][i][3] // An object of 3 name:value pairs.
+ [i][3][lat][d][29.976]
+ [i][4][long][d][31.131]
+ [i][3][alt][d][67.0]
+// No end marker since a count was specified.
+```
+Optimized with type & count
+```
+[{][$][d][#][i][3] // An object of 3 name:float32-value pairs.
+ [i][3][lat][29.976] // Value type is known, so type markers are omitted.
+ [i][4][long][31.131]
+ [i][3][alt][67.0]
+// No end marker since a count was specified.
+```
+
+---
+### Special case: Marker-only types (null, no-op & boolean)
+If using both _count_ and _type_ optimisations, the marker itself represent the value thus saving repetition (since these types to not have a payload). Additional requirements are:
+
+Strongly typed array of type no-op and with a count of 512:
+```
+[[][$][N][#][I][512]
+```
+
+Strongly typed object of type null and with a count of 3:
+```
+[{][$][Z][#][i][3]
+ [i][4][name] // name only, no value specified.
+ [i][8][password]
+ [i][5][email]
+```
