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

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.

MD007 - Unordered list indentation

Tags: bullet, ul, indentation

Aliases: ul-indent

Parameters: indent (number; default 3)

This rule is triggered when list items are not indented by the configured number of spaces (default: 2).

Example:

* List item
   * Nested list item indented by 3 spaces

Corrected Example:

* List item
  * Nested list item indented by 2 spaces

Rationale (3 space indent): This matches the minimum possible indentation for ordered lists (i.e Kramdown won't parse anything less than 3 spaces as a sublist on OLs), and since MD005 requires consistent indentation across lists, anything less than three on this rule will cause a violation of MD005 if you have both kinds of lists in the same document.

This means if you want to set this to 2, you'll need to disable MD005.

Rationale (4 space indent): Same indent as code blocks, simpler for editors to implement. See https://cirosantilli.com/markdown-style-guide#spaces-before-list-marker for more information.

In addition, this is a compatibility issue with multi-markdown parsers, which require a 4 space indents. See http://support.markedapp.com/discussions/problems/21-sub-lists-not-indenting for a description of the problem.
