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
Implement support for starting ordered lists at an arbitrary number
Closes#377
BREAKING CHANGE: Since showdown now supports starting ordered lists
at an arbitrary number, list output may differ.
Wrapping base64 strings, which are usually extremely long lines of text, is now supported.
Newlines can be added arbitrarily, as long as they appear after the comma (,) character.
Closes#429
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.
Previously, `<code>` tags were not escaped. This was counter intuitive since ´<pre><code>` tags
were being escaped. Now both pre code and code are escaped.
Closes#339
Empty lines should not be parsed as paragraphs. This was happening
in determined circumstances.
For instance, when stripping reference style links, `\n\n` was left being,
creating an undesired empty paragraph. This commit fixes the issue.
Closes#334
The way showdown parsed cases suchs as this:
```
**foo **bar
__foo __bar
*foo *bar
_foo _bar
```
was inconsistent. This established that `__` or `**` preceeding a word
would not be parsed as em or strong.
Closes#332
This option enables users to define the generated links in @mentions.
For instance, with ghMentionsOption set to `//mysite.com/{u}/profile`
this text
`@tivie`
will result in this link
`<a href="//mysite.com/tivie/profile">@tivie</a>`
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
Horizontal rule syntax allows up to 3 spaces preceding dashes or
asterisks. Commit da8fb53 wrongfully removed that. This commit
puts that back.
Closes#317
This input: `- - - a` causes trouble for the parser,
since it interprets it as multiple sublists, where it should
only interpert it as a list with a single list item.
This commit fixes this behavior.
Closes#312
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
Acording to the spec, multi paragraph (or block) list item requires subblocks
to be indented 4 spaces (or 1 tab). Although, this is mentioned in the documentation,
Showdown didn't enforce this rule in sublists because other implementations,
such as GFM also didn't. However, in some edge cases, this led to inconsistent behavior,
as shown in issue #299. This commit makes 4 space indentation in sublists
mandatory.
BREAKING CHANGE: syntax for sublists is more restrictive. Before, sublists SHOULD be
indented by 4 spaces, but indenting 2 spaces would work. Now, sublists MUST be
indented 4 spaces or they won't work.
With this input:
```md
* one
* two
* three
```
Before (ouput):
```html
<ul>
<li>one
<ul>
<li>two
<ul><li>three</li></ul>
<li>
</ul>
</li>
<ul>
```
After (output):
```html
<ul>
<li>one</li>
<li>two
<ul><li>three</li></ul>
</li>
</ul>
```
To migrate either fix source md files or activate the option `disableForced4SpacesIndentedSublists` (coming in v1.5.0):
```md
showdown.setOption('disableForced4SpacesIndentedSublists', true);
```
Nested ul and ol lists behave inconsistently in the requirement
of having 3 spaces to be considered a nested list.
This fix changes the requirement to only one space in
both cases.
Closes#299
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
