prettier-plugin-sentences-per-line allows you to enforce that no line in your Markdown files contains more than one sentence.

This is useful because:

• Shorter lines result in simpler, easier-to-understand Git diffs
• Longer lines are harder to read in source code

- First sentence. Second sentence.
+ First sentence.
+ Second sentence.

Usage

First install this package as a devDependency:

npm i -D prettier-plugin-sentences-per-line

Then add it to your Prettier config's plugins:

{
	"plugins": ["prettier-plugin-sentences-per-line"]
}

Sentences within Markdown table rows are left alone, as splitting a row across lines would break the table.

Options

These will be added to the standard list of abbreviations below.

["eg.", "e.g.", "etc.", "ex.", "ie.", "i.e.", "vs."]

{
	"plugins": ["prettier-plugin-sentences-per-line"],
	"sentencesPerLineAdditionalAbbreviations": ["I.M."]
}
