API

This module exports the identifier factoryWhitespaceapi-factory-whitespace. There is no default export.

• line endings or spaces in markdown are often optional, in which case this

factory can be used and `ok` will be switched to whether spaces were found
or not

• one line ending or space can be detected with

[`markdownLineEndingOrSpace(code)`][ws] right before using
`factoryWhitespace`

Parameters

• effects (Effects)

— context

• ok (State)

— state switched to when successful

Returns

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, micromark-factory-whitespace@^2, compatible with Node.js 16. This package works with micromark@^3.

Security

This package is safe. See security.mdsecuritymd in micromark/.githubhealth for how to submit a security report.
