BREAKING CHANGE:
CLI tool now uses the same option defaults as showdown main library. This mean
the default flavor is vanilla and ghCodeBlocks options is enabled by default.
To update, add `--ghCodeBlocks="false"` to the command.
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
