### Note
Currently very much a WIP effort.
This is currently very much a WIP effort with two branches to take note of. The first uses GtkSource.View widget to handle text edits and display. The second uses the Gtk Webkit2 widget along with Ace Editor to handle text editing. The first is more traditional in visual design and editing. While the second is more like Vi, Vim, NeoVim.
* Move respetive sub folder content under user_config to the same places in Linux. Though, /user/share/newton can go to ~/.config folder if prefered.
* In additiion, place the plugins folder in the same app folder you moved to /usr/share/newton or ~/.config/newton .
* release/newton-with-gtksource
* release/newton-with-webkit2

The initialize request is sent as the first request from the client to the server. If the server receives a request or notification
before the initialize request it should act as follows:
1. For a request the response should be an error with code: -32002. The message can be picked by the server.
2. Notifications should be dropped, except for the exit notification. This will allow the exit of a server without an initialize request.
Until the server has responded to the initialize request with an InitializeResult, the client must not send any additional requests or
notifications to the server. In addition the server is not allowed to send any requests or notifications to the client until it has responded
with an InitializeResult, with the exception that during the initialize request the server is allowed to send the notifications window/showMessage,
window/logMessage and telemetry/event as well as the window/showMessageRequest request to the client.

"""
Determine language of source code, and pass it on to the Pygments highlighter.
Usage:
```python
code = CodeHilite(src=some_code, lang='python')
html = code.hilite()
```
Arguments:
src: Source string or any object with a `.readline` attribute.
Keyword arguments:
lang (str): String name of Pygments lexer to use for highlighting. Default: `None`.
guess_lang (bool): Auto-detect which lexer to use.
Ignored if `lang` is set to a valid value. Default: `True`.
use_pygments (bool): Pass code to Pygments for code highlighting. If `False`, the code is
instead wrapped for highlighting by a JavaScript library. Default: `True`.
pygments_formatter (str): The name of a Pygments formatter or a formatter class used for
highlighting the code blocks. Default: `html`.
linenums (bool): An alias to Pygments `linenos` formatter option. Default: `None`.
css_class (str): An alias to Pygments `cssclass` formatter option. Default: 'codehilite'.
lang_prefix (str): Prefix prepended to the language. Default: "language-".
Other Options:
Any other options are accepted and passed on to the lexer and formatter. Therefore,
valid options include any options which are accepted by the `html` formatter or
whichever lexer the code's language uses. Note that most lexers do not have any
options. However, a few have very useful options, such as PHP's `startinline` option.
Any invalid options are ignored without error.
* **Formatter options**: <https://pygments.org/docs/formatters/#HtmlFormatter>
* **Lexer Options**: <https://pygments.org/docs/lexers/>
Additionally, when Pygments is enabled, the code's language is passed to the
formatter as an extra option `lang_str`, whose value being `{lang_prefix}{lang}`.
This option has no effect to the Pygments' builtin formatters.
Advanced Usage:
```python
code = CodeHilite(
src = some_code,
lang = 'php',
startinline = True, # Lexer option. Snippet does not start with `<?php`.
linenostart = 42, # Formatter option. Snippet starts on line 42.
hl_lines = [45, 49, 50], # Formatter option. Highlight lines 45, 49, and 50.

A compilation of various Python-Markdown extensions that imitates
[PHP Markdown Extra](http://michelf.com/projects/php-markdown/extra/).
Note that each of the individual extensions still need to be available
on your `PYTHONPATH`. This extension simply wraps them all up as a
convenience so that only one extension needs to be listed when
initiating Markdown. See the documentation for each individual
extension for specifics about that extension.
There may be additional extensions that are distributed with
Python-Markdown that are not included here in Extra. Those extensions
are not part of PHP Markdown Extra, and therefore, not part of
Python-Markdown Extra. If you really would like Extra to include
additional extensions, we suggest creating your own clone of Extra
under a different name. You could also edit the `extensions` global
variable defined below, but be aware that such changes may be lost
when you upgrade to any future version of Python-Markdown.

An extension to Python Markdown which implements legacy attributes.
Prior to Python-Markdown version 3.0, the Markdown class had an `enable_attributes`
keyword which was on by default and provided for attributes to be defined for elements
using the format `{@key=value}`. This extension is provided as a replacement for
backward compatibility. New documents should be authored using `attr_lists`. However,
numerous documents exist which have been using the old attribute format for many
years. This extension can be used to continue to render those documents correctly.

"""
In version 3.0, a new, more flexible inline processor was added, [`markdown.inlinepatterns.InlineProcessor`][]. The
original inline patterns, which inherit from [`markdown.inlinepatterns.Pattern`][] or one of its children are still
supported, though users are encouraged to migrate.
The new `InlineProcessor` provides two major enhancements to `Patterns`:
1. Inline Processors no longer need to match the entire block, so regular expressions no longer need to start with
`r'^(.*?)'` and end with `r'(.*?)%'`. This runs faster. The returned [`Match`][re.Match] object will only contain
what is explicitly matched in the pattern, and extension pattern groups now start with `m.group(1)`.
2. The `handleMatch` method now takes an additional input called `data`, which is the entire block under analysis,
not just what is matched with the specified pattern. The method now returns the element *and* the indexes relative
to `data` that the return element is replacing (usually `m.start(0)` and `m.end(0)`). If the boundaries are
returned as `None`, it is assumed that the match did not take place, and nothing will be altered in `data`.
This allows handling of more complex constructs than regular expressions can handle, e.g., matching nested
brackets, and explicit control of the span "consumed" by the processor.

The order in which processors and/or patterns are applied is very important - e.g. if we first replace

apply the expressions in the following order:
* backticks and escaped characters have to be handled before everything else so that we can preempt any markdown
patterns by escaping them;
* then we handle the various types of links (auto-links must be handled before inline HTML);

Base class that inline patterns subclass.
Inline patterns are handled by means of `Pattern` subclasses, one per regular expression.
Each pattern object uses a single regular expression and must support the following methods:
[`getCompiledRegExp`][markdown.inlinepatterns.Pattern.getCompiledRegExp] and
[`handleMatch`][markdown.inlinepatterns.Pattern.handleMatch].
All the regular expressions used by `Pattern` subclasses must capture the whole block. For this
reason, they all start with `^(.*)` and end with `(.*)!`. When passing a regular expression on
class initialization, the `^(.*)` and `(.*)!` are added automatically and the regular expression
is pre-compiled.
It is strongly suggested that the newer style [`markdown.inlinepatterns.InlineProcessor`][] that
use a more efficient and flexible search approach be used instead. However, the older style

A priority sorted registry.
A `Registry` instance provides two public methods to alter the data of the
registry: `register` and `deregister`. Use `register` to add items and
`deregister` to remove items. See each method for specifics.
When registering an item, a "name" and a "priority" must be provided. All
items are automatically sorted by "priority" from highest to lowest. The
"name" is used to remove ("deregister") and get items.
A `Registry` instance it like a list (which maintains order) when reading
data. You may iterate over the items, get an item and get a count (length)
of all items. You may also check that the registry contains an item.
When getting an item you may use either the index of the item or the
string-based "name". For example:
registry = Registry()
registry.register(SomeItem(), 'itemname', 20)
# Get the item by index
item = registry[0]
# Get the item by name
item = registry['itemname']
When checking that the registry contains an item, you may use either the
string-based "name", or a reference to the actual item. For example:
someitem = SomeItem()
registry.register(someitem, 'itemname', 20)
# Contains the name
assert 'itemname' in registry
# Contains the item instance
assert someitem in registry
The method `get_index_for_name` is also available to obtain the index of
an item using that item's assigned "name".

# Your snippets
#
# Atom snippets allow you to enter a simple prefix in the editor and hit tab to
# expand the prefix into a larger code block with templated values.
#
# You can create a new snippet in this file by typing "snip" and then hitting
# tab.
#
# An example CoffeeScript snippet to expand log to console.log:
#
# '.source.coffee':
# 'Console log':
# 'prefix': 'log'
# 'body': 'console.log $1'
#
# Each scope (e.g. '.source.coffee' above) can only be declared once.
#
# This file uses CoffeeScript Object Notation (CSON).
# If you are unfamiliar with CSON, you can read more about it in the
# Atom Flight Manual:
# http://flight-manual.atom.io/using-atom/sections/basic-customization/#_cson
