MD013 - Line length

Tags: line_length

Aliases: line-length

Parameters: linelength, ignorecodeblocks, codeblocks, tables (number; default 80, boolean; default false, boolean; default true, boolean; default true)

This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.

This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.

You also have the option to exclude this rule for code blocks. To do this, set the ignore_code_blocks parameter to true. To exclude this rule for tables set the tables parameters to false. Setting the parameter code_blocks to false to exclude the rule for code blocks is deprecated and will be removed in a future release.

Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

MD001 - Header levels should only increment by one level at a time

Tags: headers

Aliases: header-increment

This rule is triggered when you skip header levels in a markdown document, for example:

# Header 1

### Header 3

We skipped out a 2nd level header in this document

When using multiple header levels, nested headers should increase by only one level at a time:

# Header 1

## Header 2

### Header 3

#### Header 4

## Another Header 2

### Another Header 3

MD013 - Line length

Tags: line_length

Aliases: line-length

Parameters: linelength, ignorecodeblocks, codeblocks, tables (number; default 80, boolean; default false, boolean; default true, boolean; default true)

This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.

This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.

You also have the option to exclude this rule for code blocks. To do this, set the ignore_code_blocks parameter to true. To exclude this rule for tables set the tables parameters to false. Setting the parameter code_blocks to false to exclude the rule for code blocks is deprecated and will be removed in a future release.

Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

MD032 - Lists should be surrounded by blank lines

Tags: bullet, ul, ol, blank_lines

Aliases: blanks-around-lists

This rule is triggered when lists (of any kind) are either not preceded or not followed by a blank line:

Some text
* Some
* List

1. Some
2. List
Some text

To fix this, ensure that all lists have a blank line both before and after (except where the block is at the beginning or end of the document):

Some text

* Some
* List

1. Some
2. List

Some text

Rationale: Aside from aesthetic reasons, some parsers, including kramdown, will not parse lists that don't have blank lines before and after them.

Note: List items without hanging indents are a violation of this rule; list items with hanging indents are okay:

* This is
not okay

* This is
  okay
