MD013 - Line length
Tags: line_length
Aliases: line-length Parameters: linelength, codeblocks, tables (number; default 80, 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 and tables. To
do this, set the code_blocks
and/or tables
parameters to false.
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.

MD012 - Multiple consecutive blank lines

This rule is triggered when there are multiple consecutive blank lines in the document:

To fix this, delete the offending lines:
Some text here

Note: this rule will not be triggered if there are multiple consecutive blank lines inside code blocks.

MD026 - Trailing punctuation in header
Tags: headers
Aliases: no-trailing-punctuation
Parameters: punctuation (string; default ".,;:!?")
This rule is triggered on any header that has a punctuation character as the last character in the line:
# This is a header.
To fix this, remove any trailing punctuation:
# This is a header
Note: The punctuation parameter can be used to specify what characters class
as punctuation at the end of the header. For example, you can set it to
'.,;:!'
to allow headers with question marks in them, such as might be used
in an FAQ.

# Introduction
- Read upRead up
- Exclude checks
MD025 - Multiple top level headers in the same document
Tags: headers
Aliases: single-h1
Parameters: level (number; default 1)
This rule is triggered when a top level header is in use (the first line of the file is a h1 header), and more than one h1 header is in use in the document:
# Top level header
# Another top level header
To fix, structure your document so that there is a single h1 header that is the title for the document, and all later headers are h2 or lower level headers:
# Title
## Header
## Another header
Rationale: A top level header is a h1 on the first line of the file, and serves as the title for the document. If this convention is in use, then there can not be more than one title for the document, and the entire document should be contained within this header.
Note: The level
parameter can be used to change the top level (ex: to h2) in
cases where an h1 is added externally.

```python

MD031 - Fenced code blocks should be surrounded by blank lines
Tags: code, blank_lines
Aliases: blanks-around-fences
This rule is triggered when fenced code blocks are either not preceded or not followed by a blank line:
Some text
```
Code block

```
Another code block
```
Some more text
To fix this, ensure that all fenced code blocks have a blank line both before and after (except where the block is at the beginning or end of the document):

Trailing spaces Open
If you want to handle higher order model as follows:
- Read upRead up
- Exclude checks
MD009 - Trailing spaces
Tags: whitespace
Aliases: no-trailing-spaces
Parameters: br_spaces (number; default: 0)
This rule is triggered on any lines that end with whitespace. To fix this, find the line that is triggered and remove any trailing spaces from the end.
The brspaces parameter allows an exception to this rule for a specific amount of trailing spaces used to insert an explicit line break/br element. For example, set brspaces to 2 to allow exactly 2 spaces at the end of a line.
Note: you have to set brspaces to 2 or higher for this exception to take effect - you can't insert a br element with just a single trailing space, so if you set brspaces to 1, the exception will be disabled, just as if it was set to the default of 0.

MD014 - Dollar signs used before commands without showing output
Tags: code
Aliases: commands-show-output
This rule is triggered when there are code blocks showing shell commands to be typed, and the shell commands are preceded by dollar signs ($):
$ ls
$ cat foo
$ less bar
The dollar signs are unnecessary in the above situation, and should not be included:
ls
cat foo
less bar
However, an exception is made when there is a need to distinguish between typed commands and command output, as in the following example:
$ ls
foo bar
$ cat foo
Hello world
$ cat bar
baz
Rationale: it is easier to copy and paste and less noisy if the dollar signs are omitted when they are not needed. See http://www.cirosantilli.com/markdown-styleguide/#dollar-signs-in-shell-code for more information.
