Syntax is:
```
__double underscores__
or
___triple unserscores___
```
Keep in mind that, with this option enabled, underscore no longer
parses as `<em>` or `<strong>`
Closes#450
Setting this option to true will prevent showdown from modifying the
prefix. This might result in malformed IDs (if, for instance, the " char is
used in the prefix). Has no effect if prefixHeaderId is set to false.
Closes#409
In code, the option appeared both as 'tableHeaderId' and 'tablesHeaderId',
although only the first form had effect. In documentation was referenced
as 'tablesHeaderId'.
Option is now fixed in code to reflex the documentation and table parser
accepts both forms, with and without an s.
Closes#412
It’s useful for non-Latin texts, where header might be, for example, in Russian, but user wants id to be in English. This feature allows user to set id for header manually, using curly braces:
## Привет, мир {hello-world}
Closes#383
correctly
When a user enters a URL with emphasis or strikethrough, the html output
were incorrect.
Now, URLs inside emphasis or strikethrough are parsed corerctly
Closes#347
If an invalid prefix was passed (a string with spaces, for instance),
the string would be added as is. This ould generate invalid ids.
Also, this makes `prefixHeaderId` option play nicely with `ghCompatibleHeaderId`, since they will
follow the same escaping rules when both options are enabled.
The option simpleLineBreaks was not working with non-ASCII characters such as chinese characters and
when lines started or ended with markdown delimiters such as `*` or `~`
Closes#318, #323
style
Github replaces spaces with dashes and removes a bunch of characters
from generated header ids ][&~$!@#*()=:/,;?+'.\
This feature implements this.
Closes # 320, closes#321
When option was enabled, `<br />` tags where being added wrongfully
between `<li>` tags, which resulted in malformed html. This commit
prevents this behavior.
Closes#316
This option enables linebreaks to always be treated as `<br />` tags
without needing to add spaces in front of the line, the same way GitHub does.
Closes#206
Using the simplifiedAutoLink option does not return the expected GFM behaviour when parsing links without a http prefix.
Previously, `www.google.com` would be parsed into `<a href="www.google.com">www.google.com</a>`.
With this fix, showdown behaves like GFM, and the result is `<a href="http://www.google.com">www.google.com</a>`
Closes#284, closes#285
