tipograph/src/presets/spaces.js

A little javascript library and command line tool that makes your written content more typographically correct.

/// #### spaces
///
/// Even that they are not visible, spaces play important role in typography. Only one word space should be used at a
/// time. Also, in some cases, there should be non-breaking space instead of normal one (for example after some special
/// symbols).
