prettier-plugin-sentences-per-line

library0.2.3jsnpmunverified

A Prettier plugin that enforces a maximum of one sentence per line in Markdown files. Current stable version is 0.2.3, with frequent releases. It uses the sentences-per-line core to parse sentence boundaries and supports custom abbreviations. Unlike the ESLint or markdownlint counterparts, this plugin integrates directly into the Prettier formatting pipeline, automatically fixing line breaks. It requires Prettier 3 and ships with TypeScript declarations.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import prettierPluginSentencesPerLine from 'prettier-plugin-sentences-per-line'

✗ const prettierPlugin = require('prettier-plugin-sentences-per-line')

CommonJS require is not supported; the plugin is ESM-only. Use import statement.

plugin

✓ plugins: ['prettier-plugin-sentences-per-line']

✗ plugins: ['./node_modules/prettier-plugin-sentences-per-line']

Use the bare package name in Prettier config – Prettier resolves it automatically.

sentencesPerLineAdditionalAbbreviations

✓ sentencesPerLineAdditionalAbbreviations: ['I.M.']

✗ additionalAbbreviations: ['I.M.']

The option key must be exactly 'sentencesPerLineAdditionalAbbreviations'. Misspelling or using a different key will be ignored.

Configures Prettier with the plugin and an additional abbreviation, then shows formatting result splitting multi-sentence lines.

// .prettierrc.json { "plugins": ["prettier-plugin-sentences-per-line"], "sentencesPerLineAdditionalAbbreviations": ["e.g.", "i.e."] } // Input Markdown: // First sentence. Second sentence. // Third sentence. // // After formatting via `npx prettier --write input.md`: // First sentence. // Second sentence. // Third sentence.
