umkay 1d077d1a4f bugdown: Remove safe_mode dependencies.
Now that we have updated python-markdown, we remove the deprecated
safe_mode. We used safe_mode to escape raw html, so now instead we
pass in an EscapeHtml markdown extension to the markdown engine.

See https://pythonhosted.org/Markdown/release-2.6.html for details on
the deprecation.

Fixes: #2037 (also addresses the remaining piece of #2043).

K.Kanakhin 7bc0c7f0d5 bugdown: Fix patterns ordering in Markdown extension.

  to correct applying them to parsed text.

Brock Whittaker 77233c7e3b bugdown: Distinguish between YouTube Videos and Image Previews.
This distinguishes between YouTube Videos and Image Previews by adding
a particular “youtube-video” class to the preview along with changing
the title to the video ID rather than the link. This serves to allow
the lightbox to ID when a lightbox preview should be treated like a
YouTube video rather than an image preview.

This also modifies the tests in bug down to expect a youtube-video class
along with the title to just be the video ID on YouTube rather than the
entire URL link.

Mohsen Ibrahim e9899e4dc9 bugdown: Fix some Python-Markdown deprecation warnings.

Tim Abbott e37b6488b8 Bugdown: Remove checked-in CodeHilite extension.
The changes that required us to fork this extension had been merged
into upstream CodeHilite, so we can remove it and switch to using the
version that comes with python-markdown.
2016-10-16 00:40:08 -07:00
umkay c028815385 bugdown: Update python-markdown to version 2.6.7.
This updates Bugdown to reflect the changes in the updated
markdown. In particular, we now pass a default config object in the
__init__ for the Bugdown extension, update the make_md_engine function
to take kwargs as opposed to a config list, and have UListProcessor
inherit from ulist as opposed to olist (which no longer works).

We update the (forked from upstream) fenced_code extension's
makeExtension to take args and kwargs, and update
FencedBlockPreprocessor __init__ method with updated Codehilite
arguments.

We update the (forked from upstream) Codehilite extension to
mirror the logic with the latest upstream Codehilite:
	Add parse_hl_lines function
	update makeExtension to take args and kwarfs instead of config
	list
	Add regex for highlight lines
	use linenums instead of linenos
	use get_formatter_by_name instead of HtmlFormatter
	user get_lexer_by_name instead of TextLexer
	add hl_lines and use_pygments arguments to the codehlite
	constructor

Eklavya Sharma 41587edd2e bugdown: Change parameter name.
Change the parameter name of some functions from 'md' to 'content',
since the name 'md' seems to be the reason why this parameter was
wrongly annotated.

Brock Whittaker 98937ac539 bugdown: Set "title" attribute to actual image title when available.
This sets the “title” attribute on the image to the actual title of
the image specified by the user in their markdown, rather than just
the URL of the full link to it.

Steve Howell 40b18094ec alert words: Refactor alert word detection.
The bugdown parser no longer has a concept of which users need which
alert words, since it can't really do anything actionable with that info
from a rendering standpoint.

Instead, our calling code passes in a set of search words to the parser.
The parser returns the list of words it finds in the message.
Then the model method builds up the list of user ids that should be
flagged as having alert words in the message.

This refactoring is a little more involved than I'd like, but there are
still some circular dependency issues with rendering code, so I need to
pass in the rather complicated realm_alert_words data structure all the way
from the action through the model to the renderer.

This change shouldn't change the overall behavior of the system, except
that it does remove some duplicate regex checks that were occurring when
multiple users may have had the same alert word.

Steve Howell a036a72db6 bugdown: Raise BugdownRenderingException.

Eklavya Sharma 05046d9288 bugdown's codehilite.py: Fix annotations in python 3 mode.
Many stubs in xml.etree.ElementTree use Union[str, bytes] as

is correct, but not useful for us since we know that we'll always
get str.  So force the return value to text_type, to supress mypy
errors.

This also requires updating the required version of oauthlib; previously an

Steve Howell ace12bcab6 Support arbitrarily nested fenced quote/code blocks.
Now we can nest fenced code/quote blocks inside of quote
blocks down to arbitrary depths.  Code blocks are always leafs.
Fenced blocks start with at least three tildes or backticks,
and the clump of punctuation then becomes the terminator for
the block.  If the user ends their message without terminators,
all blocks are automatically closed.

When inside a quote block, you can start another fenced block
with any header that doesn't match the end-string of the outer
block.  (If you don't want to specify a language, then you
can change the number of backticks/tildes to avoid amiguity.)

Most of the heavy lifting happens in FencedBlockPreprocessor.run().
The parser works by pushing handlers on to a stack and popping
them off when the ends of blocks are encountered. Parents communicate
with their children by passing in a simple Python list of strings
for the child to append to.  Handlers also maintain their own
lists for their own content, and when their done() method is called,
they render their data as needed.

The handlers are objects returned by functions, and the handler
functions close on variables push, pop, and processor.  The closure
style here makes the handlers pretty tightly coupled to the outer
run() method.  If we wanted to move to a class-based style, the
tradeoff would be that the class instances would have to marshall
push/pop/processor etc., but we could test the components more
easily in isolation.

Dealing with blank lines is very fiddly inside of bugdown.

The new functionality here is captured in the test
BugdownTest.test_complexly_nested_quote().

m.group(0) is always incorrect because python-markdown modifies your regex

duplicated).
