remark-lint-mdash-style

A remark-lint rule to enforce a consistent style for em dashes (mdash) in Markdown files. Version 1.1.1 is the current stable release, with no fixed release cadence. It offers three style options: '―' (Unicode em dash, default), '-' (single hyphen), and '--' (double hyphen). Unlike general-purpose linters, this package specifically targets mdash usage, a common typographic inconsistency. It is a lightweight plugin for the remark-lint ecosystem, primarily used in Node.js environments for CI or text processing pipelines. The package has no dependencies and is ESM-compatible but requires a CommonJS or ESM project that uses remark-lint.
