+
+Lightweight JSON-RPC 2.0 protocol implementation and asynchronous server powered by asyncio. This library is a successor of json-rpc and written by the same team.
+
+Features:
+* Full JSON-RPC 2.0 Implementation.
+* Async request manager that handles the protocol.
+* Vanilla Python, no dependencies.
+* API server setup in 1 min.
+* Same development team as `json-rpc`, largely compatible code.
+
+## Installing
+```
+$ pip install ajsonrpc
+```
+
+## Quick Start
+This package contains core JSON-RPC 2.0 primitives (request, response, etc.) and convenient backend-independent abstractions on top of them: dispatcher and request manager. These modules mirror implementation in the original json-rpc package with minor changes and improvements. Below is a summary of each module.
+
+#### Core Module
+Consists of JSON-RPC 2.0 primitives: request, batch request, response, batch response, error. It also defines base classes for custom errors and exceptions.
+
+Development principles:
+* If python object is created or modified without exceptions, it contains valid data.
+* Private state `<object>._body` contains the single source of truth. It is accessible and modifiable via getters (properties) and setters that ensure validation.
+* `body` is always a dictionary with primitive keys and values (the only exception is `response.result` that could hold any value defined by the application).
+* Constructor, getters and setters operate with JSON-RPC defined types, e.g. `response.error` always has `JSONRPC20Error` type. Most of other types are strings and numbers.
+
+Unlike json-rpc package, core module does not deal with serialization/de-serialization, this logic was moved to manager.
+
+#### Dispatcher
+Dispatcher is a dict-like object that maps method names to executables. One can think of it as an inproved dictionary, in fact it is inherited from `MutableMapping`. Some of the ways to add methods to dispatcher:
+
+```python
+# init
+d = Dispatcher({"sum": lambda a, b: a + b})
+
+# set item
+d["max"] = lambda a, b: max(a, b)
+
+# function decorator
+@d.add_function
+def add(x, y):
+    return x + y
+
+# Add class or object
+class Math:
+    def sum(self, a, b):
+        return a + b
+
+    def diff(self, a, b):
+        return a - b
+
+d.add_class(Math)
+d.add_object(Math())
+d.add_dict({"min": lambda a, b: min(a, b)})
+
+# rename function
+d.add_function(add, name="my_add")
+
+# prefix methos
+d.add_class(Math, prefix="get_")
+```
+
+#### Manager
+Manager generates a response for a request. It handles common routines: request parsing, exception handling and error generation, parallel request execution for batch requests, serialization/de-serialization. Manager is asynchronous and dackend agnostic, it exposes following common methods:
+
+```python
+# Get a response object for a single request. Used by other methods.
+async def get_response_for_request(
+    self, request: JSONRPC20Request
+    ) -> Optional[JSONRPC20Response]
+
+# Get (batch) response for a string payload. Handles de-serialization and parse errors.
+async def get_response_for_payload(
+    self, payload: str
+    ) -> Optional[Union[JSONRPC20Response, JSONRPC20BatchResponse]]
+
+# Most high-level method, returns string json for a string payload.
+async def get_payload_for_payload(self, payload: str) -> str
+```
+
+#### Vanilla Server (Demo)
+This package comes with an asyncio [Protocol-based](https://docs.python.org/3/library/asyncio-protocol.html) minimalistic server script `async-json-rpc-server`. One could think of it as a bottle-py of API servers.
+
+This was an experiment turned prototype: unlike json-rpc that requires some "shell" like Django or Flask to work, this package relies on asyncio and therefore could build on top of its [TCP server](https://docs.python.org/3/library/asyncio-protocol.html#tcp-echo-server). Indeed, JSON-RPC 2.0 is intentionally simple: server does not require views, has only one endpoint (routing is not required), only deals with json. Hence, vanilla code would be not only sufficient but likely faster than any framework.
+
+This idea of self-sufficient server was extended further: what would be the minimum interface that allows to plug application code? What if zero integration is required? Likely, this was possible with runtime method introspection: `async-json-rpc-server` parses given file with methods and exposes all of them. Let's consider an example:
+
+```python
+# examples/methods.py
+import asyncio
+
+def echo(s='pong'):
+    return s
+
+def mul2(a, b):
+    return a * b
+
+async def say_after(delay, what):
+    await asyncio.sleep(delay)
+    return what
+```
+
+To launch a server based on above methods, simply run:
+
+```
+$ async-json-rpc-server examples/methods.py --port=8888
+```
+(Ctrl+C stops the server).
+
+Single request example:
+```
+$ curl -H 'Content-Type: application/json' \
+    -d '{"jsonrpc": "2.0", "method": "echo", "id": 0}' \
+    http://127.0.0.1:8888
+
+{"jsonrpc": "2.0", "id": 0, "result": "pong"}
+```
+
+Batch request example:
+![server-example-batch](https://raw.githubusercontent.com/pavlov99/ajsonrpc/master/docs/_static/server-example-postman.png)
+
+#### Backends
+Backend support is a syntactic sugar that wraps dispatcher and manager under one api class and provides convenient boilerplate, such as handler generation. Currently supported frameworks:
+* Tornado
+* Sanic
+* Quart
+
+

+    """JSON-RPC 2.0 Request object.
+
+    A rpc call is represented by sending a Request object to a Server.
+    The Request object has the following members:
+
+    jsonrpc
+        A String specifying the version of the JSON-RPC protocol. MUST be
+        exactly "2.0".
+    method
+        A String containing the name of the method to be invoked. Method names
+        that begin with the word rpc followed by a period character (U+002E or
+        ASCII 46) are reserved for rpc-internal methods and extensions and MUST
+        NOT be used for anything else.
+    params
+        A Structured value that holds the parameter values to be used during
+        the invocation of the method. This member MAY be omitted.
+    id
+        An identifier established by the Client that MUST contain a String,
+        Number, or NULL value if included. If it is not included it is assumed
+        to be a notification. The value SHOULD normally not be Null [1] and
+        Numbers SHOULD NOT contain fractional parts [2].
+
+        The Server MUST reply with the same value in the Response object if
+        included. This member is used to correlate the context between the two
+        objects.
+
+        [1] The use of Null as a value for the id member in a Request object
+        is discouraged, because this specification uses a value of Null for
+        Responses with an unknown id. Also, because JSON-RPC 1.0 uses an id
+        value of Null for Notifications this could cause confusion in handling.
+
+        [2] Fractional parts may be problematic, since many decimal fractions
+        cannot be represented exactly as binary fractions.
+
+    Notification
+        A Notification is a Request object without an "id" member. A Request
+        object that is a Notification signifies the Client's lack of interest
+        in the corresponding Response object, and as such no Response object
+        needs to be returned to the client. The Server MUST NOT reply to a
+        Notification, including those that are within a batch request.
+
+        Notifications are not confirmable by definition, since they do not have
+        a Response object to be returned. As such, the Client would not be
+        aware of any errors (like e.g. "Invalid params","Internal error").
+
+    Parameter Structures
+        If present, parameters for the rpc call MUST be provided as a
+        Structured value. Either by-position through an Array or by-name
+        through an Object.
+
+        by-position: params MUST be an Array, containing the values in the
+            Server expected order.
+        by-name: params MUST be an Object, with member names that match the
+            Server expected parameter names. The absence of expected names MAY
+            result in an error being generated. The names MUST match exactly,
+            including case, to the method's expected parameters.
+
+    Note:
+        Design principles:
+        * if an object is created or modified without exceptions, its state is
+        valid.
+        * There is a signle source of truth (see Attributes), modification should
+        be done via setters.
+
+    Args:
+        method (str):
+            method to call.
+        params (:obj:dict, optional):
+            a mapping of method argument values or a list of positional arguments.
+        id:
+            an id of the request. By default equals to None and raises warning.
+            For notifications set is_notification=True so id would not be
+            included in the body.
+        is_notification:
+            a boolean flag indicating whether to include id in the body or not.
+
+    Attributes:
+        _body (dict): body of the request. It should always contain valid data and
+        should be modified via setters to ensure validity.
+
+    Examples:
+        modification via self.body["method"] vs self.method
+        modifications via self._body

+
+AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio_ or
+Trio_. It implements Trio-like `structured concurrency`_ (SC) on top of asyncio and works in harmony
+with the native SC of Trio itself.
+
+Applications and libraries written against AnyIO's API will run unmodified on either asyncio_ or
+Trio_. AnyIO can also be adopted into a library or application incrementally – bit by bit, no full
+refactoring necessary. It will blend in with the native libraries of your chosen backend.
+
+To find out why you might want to use AnyIO's APIs instead of asyncio's, you can read about it
+`here <https://anyio.readthedocs.io/en/stable/why.html>`_.

+
+Features
+--------
+
+AnyIO offers the following functionality:
+
+* Task groups (nurseries_ in trio terminology)
+* High-level networking (TCP, UDP and UNIX sockets)
+
+  * `Happy eyeballs`_ algorithm for TCP connections (more robust than that of asyncio on Python
+    3.8)
+  * async/await style UDP sockets (unlike asyncio where you still have to use Transports and
+    Protocols)
+
+* A versatile API for byte streams and object streams
+* Inter-task synchronization and communication (locks, conditions, events, semaphores, object
+  streams)
+* Worker threads
+* Subprocesses
+* Subinterpreter support for code parallelization (on Python 3.13 and later)
+* Asynchronous file I/O (using worker threads)
+* Signal handling
+* Asynchronous version of the functools_ module
+
+AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures.
+It even works with the popular Hypothesis_ library.

+Certifi: Python SSL Certificates
+================================
+
+Certifi provides Mozilla's carefully curated collection of Root Certificates for
+validating the trustworthiness of SSL certificates while verifying the identity
+of TLS hosts. It has been extracted from the `Requests`_ project.
+
+Installation
+------------
+
+``certifi`` is available on PyPI. Simply install it with ``pip``::
+
+    $ pip install certifi
+
+Usage
+-----
+
+To reference the installed certificate authority (CA) bundle, you can use the
+built-in function::
+
+    >>> import certifi
+
+    >>> certifi.where()
+    '/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
+
+Or from the command line::
+
+    $ python -m certifi
+    /usr/local/lib/python3.7/site-packages/certifi/cacert.pem
+
+Enjoy!
+
+.. _`Requests`: https://requests.readthedocs.io/en/master/
+
+Addition/Removal of Certificates
+--------------------------------
+
+Certifi does not support any addition/removal or other modification of the
+CA trust store content. This project is intended to provide a reliable and
+highly portable root of trust to python deployments. Look to upstream projects
+for methods to use alternate trust.

+This package contains a modified version of ca-bundle.crt:

+ca-bundle.crt -- Bundle of CA Root Certificates
+
+This is a bundle of X.509 certificates of public Certificate Authorities
+(CA). These were automatically extracted from Mozilla's root certificates
+file (certdata.txt).  This file can be found in the mozilla source tree:
+https://hg.mozilla.org/mozilla-central/file/tip/security/nss/lib/ckfw/builtins/certdata.txt
+It contains the certificates in PEM format and therefore
+can be directly used with curl / libcurl / php_curl, or with
+an Apache+mod_ssl webserver for SSL client authentication.
+Just configure this file as the SSLCACertificateFile.#

+
+## ✨ Installation
+
+Using pip:
+
+```sh
+pip install charset-normalizer -U
+```
+
+## 🚀 Basic Usage
+
+### CLI
+This package comes with a CLI.
+
+```
+usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
+                  file [file ...]
+
+The Real First Universal Charset Detector. Discover originating encoding used
+on text file. Normalize text to unicode.
+
+positional arguments:
+  files                 File(s) to be analysed
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -v, --verbose         Display complementary information about file if any.
+                        Stdout will contain logs about the detection process.
+  -a, --with-alternative
+                        Output complementary possibilities if any. Top-level
+                        JSON WILL be a list.
+  -n, --normalize       Permit to normalize input file. If not set, program
+                        does not write anything.
+  -m, --minimal         Only output the charset detected to STDOUT. Disabling
+                        JSON output.
+  -r, --replace         Replace file when trying to normalize it instead of
+                        creating a new one.
+  -f, --force           Replace file without asking if you are sure, use this
+                        flag with caution.
+  -t THRESHOLD, --threshold THRESHOLD
+                        Define a custom maximum amount of chaos allowed in
+                        decoded content. 0. <= chaos <= 1.
+  --version             Show version information and exit.
+```
+
+```bash
+normalizer ./data/sample.1.fr.srt
+```
+
+or
+
+```bash
+python -m charset_normalizer ./data/sample.1.fr.srt
+```
+
+🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.
+
+```json
+{
+    "path": "/home/default/projects/charset_normalizer/data/sample.1.fr.srt",
+    "encoding": "cp1252",
+    "encoding_aliases": [
+        "1252",
+        "windows_1252"
+    ],
+    "alternative_encodings": [
+        "cp1254",
+        "cp1256",
+        "cp1258",
+        "iso8859_14",
+        "iso8859_15",
+        "iso8859_16",
+        "iso8859_3",
+        "iso8859_9",
+        "latin_1",
+        "mbcs"
+    ],
+    "language": "French",
+    "alphabets": [
+        "Basic Latin",
+        "Latin-1 Supplement"
+    ],
+    "has_sig_or_bom": false,
+    "chaos": 0.149,
+    "coherence": 97.152,
+    "unicode_path": null,
+    "is_preferred": true
+}
+```
+
+### Python
+*Just print out normalized text*
+```python
+from charset_normalizer import from_path
+
+results = from_path('./my_subtitle.srt')
+
+print(str(results.best()))
+```
+
+*Upgrade your code without effort*
+```python
+from charset_normalizer import detect
+```
+
+The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
+
+See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
+
+## 😇 Why
+
+When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
+reliable alternative using a completely different method. Also! I never back down on a good challenge!
+
+I **don't care** about the **originating charset** encoding, because **two different tables** can
+produce **two identical rendered string.**
+What I want is to get readable text, the best I can.
+
+In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
+
+Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
+
+## 🍰 How
+
+  - Discard all charset encoding table that could not fit the binary content.
+  - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
+  - Extract matches with the lowest mess detected.
+  - Additionally, we measure coherence / probe for a language.
+
+**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
+
+*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
+**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text).
+ I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
+ improve or rewrite it.
+
+*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
+that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
+
+## ⚡ Known limitations
+
+  - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
+  - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
+

+
+## [2.0.2](https://github.com/Ousret/charset_normalizer/compare/2.0.1...2.0.2) (2021-07-15)
+### Fixed

+
+### Changed
+- Don't inject unicodedata2 into sys.modules from [@akx](https://github.com/akx) (PR #57)
+
+## [2.0.1](https://github.com/Ousret/charset_normalizer/compare/2.0.0...2.0.1) (2021-07-13)
+### Fixed
+- Make it work where there isn't a filesystem available, dropping assets frequencies.json. Report from [@sethmlarson](https://github.com/sethmlarson). (PR #55)

+
+## [2.0.0](https://github.com/Ousret/charset_normalizer/compare/1.4.1...2.0.0) (2021-07-02)
+### Changed
+- 4x to 5 times faster than the previous 1.4.0 release. At least 2x faster than Chardet.
+- Accent has been made on UTF-8 detection, should perform rather instantaneous.
+- The backward compatibility with Chardet has been greatly improved. The legacy detect function returns an identical charset name whenever possible.
+- The detection mechanism has been slightly improved, now Turkish content is detected correctly (most of the time)
+- The program has been rewritten to ease the readability and maintainability. (+Using static typing)+
+- utf_7 detection has been reinstated.
+
+### Removed
+- This package no longer require anything when used with Python 3.5 (Dropped cached_property)

+
+### Deprecated
+- Methods coherence_non_latin, w_counter, chaos_secondary_pass of the class CharsetMatch are now deprecated and scheduled for removal in v3.0
+
+### Fixed
+- The CLI output used the relative path of the file(s). Should be absolute.
+
+## [1.4.1](https://github.com/Ousret/charset_normalizer/compare/1.4.0...1.4.1) (2021-05-28)
+### Fixed

+
+## [1.4.0](https://github.com/Ousret/charset_normalizer/compare/1.3.9...1.4.0) (2021-05-21)
+### Removed
+- Using standard logging instead of using the package loguru.
+- Dropping nose test framework in favor of the maintained pytest.
+- Choose to not use dragonmapper package to help with gibberish Chinese/CJK text.
+- Require cached_property only for Python 3.5 due to constraint. Dropping for every other interpreter version.
+- Stop support for UTF-7 that does not contain a SIG.
+- Dropping PrettyTable, replaced with pure JSON output in CLI.
+
+### Fixed
+- BOM marker in a CharsetNormalizerMatch instance could be False in rare cases even if obviously present. Due to the sub-match factoring process.
+- Not searching properly for the BOM when trying utf32/16 parent codec.
+
+### Changed
+- Improving the package final size by compressing frequencies.json.
+- Huge improvement over the larges payload.
+
+### Added
+- CLI now produces JSON consumable output.
+- Return ASCII if given sequences fit. Given reasonable confidence.
