import est from '@frantic1048/Est'

// directly render rST into HTML string
const html = est.rst2html('reStructuredText string...')


// or...?
// welcome to the dark side...

// generate parsing tree
// which is an ASTy instance
const parse_t = est.parse('reStructuredText string...')

// transfrom parsing tree into doc tree
// which is an ASTy instance
const doc_t = est.transfrom(parse_t)

// render the doc tree into HTML string
const html_the_harder_way = est.render(doc_t)

All node types of the parsed tree can be found from est.TokenTypes .
