)heading_line_length
: Number of characters for headings (integer

)headings

, defaulttrue

: Number of characters (integer

If
headings
is not provided,headers
(deprecated) will be used.
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. To set a different maximum length for headings, use
heading_line_length
. To set a different maximum length for code blocks, use
code_block_line_length
This rule has an exception when 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. To disable this exception, set the
strict
parameter to true
to report an issue when any line is too long.
To warn for lines that are too long and could be fixed but allow lines without
spaces, set the stern
parameter to true
.
For example (assuming normal behavior):
IF THIS LINE IS THE MAXIMUM LENGTH
This line is okay because there are-no-spaces-beyond-that-length
And this line is a violation because there are
This-line-is-also-okay-because-there-are-no-spaces
In strict
or stern
modes, the two middle lines above are a violation. The
third line is a violation in strict
mode but allowed in stern
mode.
You have the option to exclude this rule for code blocks, tables, or headings.
To do so, set the code_blocks
, tables
, or headings
parameter(s) 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.
Rationale: Extremely long lines can be difficult to work with in some editors. More information: https://cirosantilli.com/markdown-style-guide#line-wrapping.
